Strange light descends near the Popocatépetl Volcano (Video)
Strange light descends near the Popocatépetl Volcano (Video)
On January 18, 2021 the Popocatépet Volcano live webcam recorded an eerie light apparently descending near the volcano.
The Popocatépetl volcano area located in the states of Puebla, Mexico is well known for its UFO Sightings and eerie lights moving above and near the volcano and now with this strange descending light we can add a new mystery to the many unexplained events happening in this area.

Richard Dolan: The astonishing 1961 Abduction Case
Everyone knows about the 1961 UFO encounter of Betty and Barney Hill. But three months prior to that, another (mostly unknown) event took place involving two young people on Long Island, Peter Robbins and his sister Helen.
While Peter went on years later to become a well-known UFO researcher, Helen became a famous Punk Rock star. Here, in a well-illustrated video interview, Peter describes what happened to Helen, and how it affected both of their lives in a powerful way.
The Lonnie Zamora incident was an alleged UFO sighting that occurred on April 24, 1964 near Socorro, New Mexico when Socorro police officer Lonnie Zamora claimed he saw two people beside a shiny object that later rose into the air accompanied by a roaring flame.
The six-wheeled robotic explorer, which remains on track to touch down on Mars on Feb. 18, has been reproduced by Mattel as a Hot Wheels toy. The release of the 1:64th-scale vehicle has been timed to precede the real rover's landing on the red planet so fans of both the mission and the miniatures can reenact the event as it happens.
"We want the car to be out there so kids have it in their hands when the actual rover lands in February," said Manson Cheung, staff sculptor and lead 3D modeler for Mattel Hot Wheels. "We want kids to be like, 'Oh, I have the rover in my hand and I can see it on Mars,' so there is a connection for the kids, not only with Hot Wheels, but space as well."
Launched from Earth on July 30, 2020, Perseverance is nearing its destination and beginning NASA's first mission dedicated to searching for and caching signs of life for a future return to Earth. Should the rover survive its plunge into Mars' atmosphere and a seven-minute descent to the surface that requires an aeroshell, parachute, retro-rockets and a "sky crane" to all autonomously work as designed, then the Perseverance rover will explore Jezero Crater on the western edge of a giant impact basin, just north of the planet's equator.
"NASA's Perseverance rover, just in its name, goes hand-in-hand with Hot Wheels' spirt of 'Challenge Accepted," Scott Shaffstall, senior public relations manager for vehicles, action figures and licenses at Mattel, said. "It's very much tied that vision of try, fail, repeat until it is done right."
"So in our mind, this mission is already a success as it is moving the needle and getting us one step closer to Mars," said Shaffstall.

Like the real Perseverance, which was based on the design of NASA's previous and still active rover, Curiosity, the Hot Wheels Perseverance reuses the mold for Mattel's 2012 toy of the earlier-landed, car-sized explorer.
But the two rovers are not identical. Perseverance is equipped with a different set of science instruments, including a redesigned robotic arm, and has more robust wheels after the lessons learned with Curiosity's mobility system.
"We were in talks with JPL [the Jet Propulsion Laboratory in Pasadena, California] and NASA and we worked out that the differences at our scale, at 1:64th or about 3 inches [8 cm], would be very close in appearance. So we were able to reuse the Curiosity mold and brand it as Perseverance," Cheung told collectSPACE.com.
Identical to the Hot Wheels Curiosity, the Perseverance version of the toy includes NASA's insignia on its undercarriage and features a rotating camera mast. Mattel also incorporated the reddish-brown Mars "soiled" wheels that it first introduced on a reissue of the Curiosity rover toy in 2014.
"So with Curiosity/Perseverance, it is sort of following the same model as what we do generally in Hot Wheels, reusing the same sculpt that is very similar and just rebranding it as something else," said Cheung.
Persistent partnership

The Mars Perseverance Rover, which retails for $1.09, is part of the Hot Wheels "Space" line for 2021, an assortment of five different vehicles each with a space or cosmic theme.
"The space mini-collection was brought back in 2021 due to the increased interest from kids and the general public in regards to space exploration. The rover was an obvious fit and we knew that it would be touching down on Mars," said Shaffstall.
The Perseverance toy continues a long history of Hot Wheels celebrating NASA's missions and working with the engineers at JPL in Pasadena, California.
In addition to the Curiosity rover, Hot Wheels sets have also been modeled after NASA's Mars Pathfinder mission in 1997, John Glenn's return to space in 1999 and the Galileo mission to Jupiter that same year. NASA and Hot Wheels began collaborating in the 1980s with the development and release of the Space Shuttle Ground Support Hiway Hauler.
The partnership has led to Mattel designers visiting and touring JPL to get a look at real space vehicles and to deliver their Hot Wheels toys of the same spacecraft to the missions' team members.
"I don't think we are going to be there on landing day because it is all going to be hectic, but we definitely will get the [Hot Wheels Perseverance Rover] samples to them when we can," Shaffstall said.
Even the greatest of us have to take those around us into account. It’s true on a social level and, as new research shows, it’s true on an astronomical level as well.

Planets and the moons that orbit them form interdependent systems in which both influence one another. We see this with our Moon being tidally locked to our planet, while it, in turn, exerts its gravitational influence on Earth’s oceans.
These are undeniably massive effects that the two bodies exert on one another. But they’re not the most dramatic ones we’ve found so far. A new paper reports that Saturn, one of the titans of our Solar system, has a tilted rotation axis — and, according to the team, this is the doing of its moons.
Bowing to influence
The team, with members from CNRS (France’s national research center), Sorbonne University, and the University of Pisa working with the Paris Observatory report that Saturn’s satellites can explain the mystery of its tilted axis. They also predict that the planet will keep tilting in the future for a few billion years.
This tilt is caused by the gravitational pull of Saturn’s moons as they migrate away from their host planet. Titan, Saturn’s largest natural satellite, bears the lion’s share of the blame, they add.
Saturn’s moons are gradually wrestling free of the giant’s gravitational influence and are slowly inching away from it. While we were aware this was happening, the study showcases that the process is unfolding much faster than previously estimated. By using the new migration rate into our models and calculations, the team concluded that it is, in fact, tied to the planet’s tilt. Furthermore, as Saturn’s moons get further away from the planet, its tilt will keep increasing.
However, a decisive event (in regards to Saturn’s tilt) likely occurred recently in cosmological terms, the team adds. For around three billion years after its formation, Saturn’s axis was only slightly tilted; however, around one billion years ago, the tilting process took root.
At that time, the team explains, the movement of Saturn’s moons triggered a “resonance phenomenon” that continues to this day. We’re seeing the middle stages of this phenomenon currently. While this was already known as well, it was assumed that it started four billion years ago due to a change in Neptune’s orbit and that Saturn’s orbit today is stable — now we know neither are true. Over the next billion years or so, Saturn’s inclination relative to its axis could more than double.
Jupiter, the team adds in a different paper, is likely to undergo a similar tilting with the migration of its own moons due to the influence of Uranus. This process will likely take place over five billion years, says the team, and could take it from its current inclination of 3° to more than 30°.
The first paper “The large obliquity of Saturn explained by the fast migration of Titan” has been published in the journal Nature Astronomy.
The second paper “The future large obliquity of Jupiter” has been published in the journal Astronomy & Astrophysics.
Enthusiasm over a Venusian compound associated with life has been quenched by a new study. It’s probably just sulfur dioxide, researchers now believe.

Phosphine is a colorless, flammable, toxic gas compound — not something you’d be thrilled to see in most cases. But back in September, researchers got really excited about phosphine because it detected in the atmosphere of Venus.
For all its toxicity, phosphine can be produced by life. Finding phosphine on the hellish Venus suggests that life could perhaps exist on Venus, which understandably made a lot of astronomers very curious.
But right from the get-go, some were skeptical about the study. Just one month later, another group of researchers tried to find the phosphine themselves (using telescopes),but couldn’t. Two other groupsreprocessedthe same data used in the first study and alsocouldn’t find evidence for phosphine.
“The authors have informed the editors of Nature Astronomy about an error in the original processing of the ALMA Observatory data underlying the work in this Article, and that recalibration of the data has had an impact on the conclusions that can be drawn. Nature Astronomy is working with the authors to resolve the matter.”
“Instead of phosphine in the clouds of Venus, the data are consistent with an alternative hypothesis: They were detecting sulfur dioxide,” said co-author Victoria Meadows, a UW professor of astronomy. “Sulfur dioxide is the third-most-common chemical compound in Venus’ atmosphere, and it is not considered a sign of life.”
Instead of looking for the phosphine in the telescope data, Meadows and colleagues tried a different approach: they created models of what could be observed on Venus. They found that sulfur dioxide can not only explain the observations, but is also consistent with what we already know of Venus.
Venus is as mysterious as ever. Image credits: NASA / JPL.
The initial phosphine study used the Atacama Large Millimeter/submillimeter Array (ALMA) and the James Clerk Maxwell Telescope (JCMT) to make the observations, focusing on the 266.94 gigahertz frequency. Both phosphine and sulfur dioxide absorb radio waves close to this frequency. So what researchers observed could have been sulfur dioxide. The new study modelled how the signals would be picked up by the JCMT and ALMA telescopes.
“This is what’s known as a radiative transfer model, and it incorporates data from several decades’ worth of observations of Venus from multiple sources, including observatories here on Earth and spacecraft missions like Venus Express,” said lead author Andrew Lincowski, a researcher with the UW Department of Astronomy.
There’s another reason why the previous observations are very unlikely to be phosphine, researchers say: the initial signal was found not in the planet’s cloud layer, but far above it, where phosphine would likely be destroyed within seconds, but sulfur dioxide would be more stable.
“Phosphine in the mesosphere is even more fragile than phosphine in Venus’ clouds,” said Meadows. “If the JCMT signal were from phosphine in the mesosphere, then to account for the strength of the signal and the compound’s sub-second lifetime at that altitude, phosphine would have to be delivered to the mesosphere at about 100 times the rate that oxygen is pumped into Earth’s atmosphere by photosynthesis.”
The team also found that the ALMA antenna configuration had an unfortunate side effect: signals from gases like sulfur dioxide give off weaker signals than gases distributed over a smaller scale.
“They inferred a low detection of sulfur dioxide because of that artificially weak signal from ALMA,” said Lincowski. “But our modeling suggests that the line-diluted ALMA data would have still been consistent with typical or even large amounts of Venus sulfur dioxide, which could fully explain the observed JCMT signal.”
“When this new discovery was announced, the reported low sulfur dioxide abundance was at odds with what we already know about Venus and its clouds,” said Meadows. “Our new work provides a complete framework that shows how typical amounts of sulfur dioxide in the Venus mesosphere can explain both the signal detections, and non-detections, in the JCMT and ALMA data, without the need for phosphine.”
So where does this leave us? We know that Earth’s atmosphere contains small amounts of phosphine, and life may produce phosphine. At this point, it seems more likely that previous observations aren’t of phosphine. But venus also remains as mysterious and ever — with a toxic atmosphere, acidic clouds, and scorching hot temperatures, it’s not the place where you’d expect any life form to exist. Then again, we can’t say that for sure, either.
'Mission accomplished': UAE's Hope probe safely enters Mars' orbit – beating both NASA and China to the Red Planet following a 500-million-km race from Earth
'Mission accomplished': UAE's Hope probe safely enters Mars' orbit – beating both NASA and China to the Red Planet following a 500-million-km race from Earth
United Arab Emirates' orbiter Hope reached Martian orbit on Tuesday afternoon
Hope will be followed by China's Tianwen-1 orbiter-rover combo on Wednesday
NASA's Perseverance rover will touch down in Jezero crater on February 18
The United Arab Emirates has become the first Arab nation and only the fifth nation overall to place a spaceship in orbit around Mars.
The country's space probe, called Hope, officially entered Mars orbit at around 16:15 GMT on Tuesday, marking the completion of a 493 million km journey from Earth.
Hope will be the first probe to provide a complete picture of planet's atmosphere and its layers, according to the UAE.
It will answer key questions about the loss of hydrogen and oxygen gases into space, over the span of one Martian year (687 Earth days).
It's arrived ahead of two other spacecraft from NASA and China – although unlike those crafts, Hope is an orbiter probe and won't be landing on the planet's surface.
China's orbiter and rover combo – named Tianwen-1 – will arrive into Martian orbit tomorrow, followed by NASA's Perseverance rover on February 18.
Named Hope, the probe started the complex process of entering Martian orbit at just before 16:00 GMT - following a 500 million km race from Earth
Illustration provided by Mohammed Bin Rashid Space Centre depicts the United Arab Emirates' Hope Mars probe during its approach
It's arrived ahead of NASA and Chinese spaceships, also on their way to the Red Planet - but unlike those crafts, this one won't be landing as it is an orbiter probe.
MARS ORBITAL INSERTION: A COMPLICATED PROCESS
Entering Martian orbit isn't an easy process, according to scientists.
The stresses on the spacecraft of all engines firing at once are far beyond those at launch
The probe fired its rockets to rapidly decelerate to achieve Mars Orbital Insertion (MOI).
During the MOI the spacecraft rotated to position for a deceleration burn of 27 minutes, and slowed down from its cruising speed of 121,000 km/h to 18,000 km/h.
The stresses on the spacecraft of all engines firing at once are far beyond those at launch.
It happened with a 20-odd-minute radio delay to Earth - so the probe had to manage on its own.
The UAE, China and the US took advantage of a period last July when Mars and Earth were favourably aligned to launch their exploratory missions to the Red Planet.
'Success! Contact with #HopeProbe has been established again. The Mars Orbit Insertion is now complete,' the Hope Mars Mission Twitter account posted.
Hope started the complex process of entering Martian orbit today just before 16:00 GMT – seven months after its blast-off from Japan's Tanegashima Space Center on July 19 last year.
This 'most critical and complex' manoeuvre involved Hope firing its engines and slowing itself down sufficiently to be captured by the gravity of the Red Planet – known as the fuel burn and 'Mars Orbit Insertion (MOI)' phase.
By firing Hope's engines for 27 minutes, the fuel burn reduced the speed of Hope from more than 121,000 km an hour to approximately 18,000 km an hour as it entered the 'capture orbit' and disappeared behind Mars' dark side.
Signals from the spacecraft, confirming a successful orbital insertion, arrived 11 minutes later at the Mohammed bin Rashid Space Centre, Dubai.
Hope re-emerged from the planet's shadow, and contact was restored on schedule after a nervy wait, sparking jubilant celebrations in the city.
Hope will remain in this phase for about two months, during which further testing of its instrumentation will take place, until it is ready to enter the 'science' orbit – when its data collection work begins.
In science orbit, it will be in an especially high position – 13,670 miles by 27,340 miles (22,000 kilometres by 44,000 kilometres) above the Martian surface – and provide regular updates on the Martian weather.
It will survey Mars' atmosphere, around 95 per cent of which is made up of carbon dioxide, around the entire planet, at all times of day and in all seasons.
In science orbit, it will complete one orbit of the planet every 55 hours.
While it will be in daily contact with Earth during the capture orbit phase, in its science orbit, contacts will take place two to three times a week.
Each pass will be six to eight hours long, which is the only time the UAE team will have to download any data and send the probe any new updates or instructions.
Omran Sharaf, Emirates Mars Mission (Hope Probe) project director, Mohammed Bin Rashid Space Centre, said: 'MOI was the most critical and dangerous part of our journey to Mars, exposing the Hope probe to stresses and pressures it has never before faced.
'While we have spent six years designing, testing and retesting the system, there is no way to fully simulate the impacts of the deceleration and navigation required to achieve MOI autonomously.
'With this enormous milestone achieved, we are now preparing to transition to our science orbit and commence science data gathering.'
Also known as Amal – which is Arabic for Hope – this is the first deep space mission for the Gulf nation, which has long-term ambitions for a Martian colony.

Hope launched first on July 19 from Japan and is designed to take readings from the Martian atmosphere over the span of an entire Martian year - or nearly two Earth years
The UAE Mars Hope satellite launched from Japan on July 19 and entered Mars' orbit on February 9. It will monitor the weather on the Red Planet
Sensors will help reveal the secrets of Martian climate
UAE's Amal orbiter will have three sensors on-board to help astronomers learn more about Mars's climate.
The third sensor will be an ultraviolet spectrometer for measuring oxygen and hydrogen levels
One will be a high-resolution camera dedicated to tracking dust movements and the ozone of Mars.
This will scan a range of light frequencies.
Another device will specifically focus on infrared and was built by scientists at Arizona State University.
This IR camera will measure both the upper and lower atmosphere.
The third sensor will be an ultraviolet spectrometer for measuring oxygen and hydrogen levels.
Hope will provide the first planet-wide picture of Mars' weather system and climate throughout the Martian year, a UAE spokesperson said.
'The data collected during this time will be open to scientists globally, contributing to humanity's shared understanding of our second-closest planet.'
Sarah bint Yousef Al Amiri, chairwoman of the UAE Space Agency, said she hopes the mission will be in a position to share data by September.
'One of our primary objectives is to ensure that we share the data as soon as we are comfortable, as a science team, that the data is usable by scientists and the data is correct.
'We hope to release the data at the latest in the beginning of September, and it will be data from the capture orbit that has been captured around Mars, and also from the beginning of our science phase.'
She added: 'A lot of what we're hoping to discover from the data of this mission is new, and this is a highly complimentary mission to other missions so we truly hope that others' missions around Mars will utilise also our data.
'And there's actually talks with a few teams, who have spacecrafts around Mars, to see how we can further collaborate and expand all of our science so analysis capabilities utilising more and more data.'
Hope is to be followed by the NASA Perseverance rover and the China Tianwen-1 rover-orbiter combination craft.
Unlike Hope, these craft will be searching for signs of ancient life on the Red Planet's rusty red surface, which is thought to have once been Earth-like.
Tianwen-1 is due to enter Mars orbit on Wednesday, February 10, but it will remain paired in orbit until May, when the rover separates to descend to the surface.
Once the rover gets to Mars, it will survey the composition, types of substance, geological structure and meteorological environment of the Martian surface, and look for signs of alien life.
China successfully launched Tianwen-1 on July 23 aboard a Long March 5 Y-4 carrier rocket from Wenchang Space Launch Centre on the southern island province of Hainan, China.
Both the UAE and China are newcomers to Mars, where more than half of Earth's emissaries have failed.
China's mission includes a Mars orbiter, that will carry the lander and rover until release, a lander, that will parachute down the the surface carrying the rover, and a rover that will study the planet's soil and atmosphere for signs of life
Perseverance, which was the last of the three to blast off last July, will land on the Martian surface on February 18.
The one-ton Perseverance rover is larger and more elaborate than Tianwen-1's rover, but it will similarly prowl for signs of ancient microscopic life.
'To say we're pumped about it, well that would be a huge understatement,' said Lori Glaze, NASA's planetary science director.
About the size of an SUV, the rover will dive in straight away for a harrowing sky-crane touchdown at the 30-mile-diameter Jezero Crater – an ancient river delta that seems a logical spot for somewhere that once harboured life.
Perseverance rover fires up its descent stage engines as it nears the Martian surface in this NASA illustration
Perseverance is carrying seven instruments that will analyse samples from the surface, including an advanced panoramic camera, a ground-penetrating radar and an X-ray fluorescence spectrometer for analysis of chemical elements.
The NASA rover, which launched from Florida on July 30, will set the samples aside for retrieval by a fetch rover launching in 2026.
Under an elaborate multi-billion plan still being worked out by NASA and the European Space Agency, the geologic treasure would arrive on Earth in the early 2030s.
One of the biggest questions is whether life has existed beyond Earth, and Mars is a good place to start investigating, given that evidence points to it once being full of water, warmer and with a thicker atmosphere.
Future missions, including from the European Space Agency and Japan, will bring samples of Martian soil and rock back to the Earth for study.
SpaceX is planning to send an uncrewed mission to Mars using its Starship rocket by 2024 and with a crew by 2026.
There are currently six spacecraft operating around Mars – three from the US, two from Europe and one from India, but the UAE has made it seven with its mission.
THREE MISSIONS TO MARS IN THE SPACE OF 10 DAYS
There are three major missions bound for Mars in the space of just 10 days this month - the UAE's Hope orbiter, China's Tianwen-1 craft and NASA's Perseverance rover.
The countries are taking advantage of a period when Earth and Mars are favourably aligned for a relatively short journey.
July 19: Hope (UAE)
The 3,000lb (1,350kg) craft (pictured) will complete one orbit every 55 hours for a total of one Martian year — 687 Earth days
- The 2,970-pound probe was built entirely within the Emirates, launched from Japan and will take seven months to reach the Red Planet.
- When the orbiter gets there in February 2021, it will stay in orbit for a whole Martian year – 687 days.
- Hope will not land on the Martian surface but take readings from the Red Planet's atmosphere.
- Hope will help answer key questions about the Martian atmosphere and the loss of hydrogen and oxygen gases into space over the span of one Martian year – called a 'sol'.
- Three instruments mounted on the probe will provide a picture of Mars's atmosphere throughout the year, and all of the data gathered will be made widely available.
- This includes an infrared spectrometer to measure the lower atmosphere and temperature, a high-resolution imager to study the ozone and another to look at levels of hydrogen and oxygen up to 27,000 miles from the surface.
July 23: Tianwen-1
The Chinese space exploration authority introduced the nation's first Mars rover Tianwen-1 (pictured) at a grand ceremony earlier this month. The rover measures just over six feet in height
- This robotic spacecraft consists of an orbiter (stationed in the atmosphere), a lander (stationary on the planet's surface) and a rover (roaming the surface).
- The craft measures just over six feet in height (1.85m) and weighs 530 pounds (240kg).
- It will survey the composition, types of substance, geological structure and meteorological environment of the Martian surface.
- The solar-powered machine is designed to work on Mars for three Martian months, about 92 Earth days.
- It includes a geological camera, a multispectral camera, a subsurface detection radar, a surface composition detector, a surface magnetic field detector and a weather detector.
- A poem pondering on the stars and planets written over 2000 years ago was the inspiration for the name of China's first exploration mission to Mars.
- Called Tianwen (天问), the poem was written by ancient Chinese literati and politician Qu Yuan (339-278BC), who lived in the Chu State (770-223BC).
July 30: Perseverance
NASA's Mars 2020 Rover will pick up samples of rock and soil from the red planet, deposit them in tubes and leave them on the ground for a future mission to return them to Earth.
- NASA's Perseverance rover is the heaviest payload yet to go to the Red Planet - at a car-sized 2,259 pounds (1,025kg).
The mission will seek signs of past microbial life on Mars and collect rock and soil samples for eventual return to Earth.
- The Mars Perseverance rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a 'cache' on the surface of Mars.
- The rover will travel using an ultraviolet laser to determine what minerals and compounds are present in the soil, based on the way the light scatters.
- The Mars 2020 rover, which was built at NASA's Jet Propulsion Laboratory in Pasadena, California., is now at the Kennedy Space Center in Florida for final preparations.
- It launches to space on July 30 and is set to touch down on Mars in 12 months.
- It has a mission duration of 1 Mars year (668 sols or 687 Earth days) and will touch down on the planet's Jezero crater on Mars in February 2021.
The Hope probe successfully entered Martian orbit at 16.00 UTC on 9 February 2021.

The United Arab Emirates’ Hope spacecraft has entered Martian orbit, completing the riskiest part of its two-year mission. The feat makes the United Arab Emirates (UAE) the fifth player to successfully reach Mars, following European, Indian, Russian and US space agencies. Hope is part of the first interplanetary mission by any Arab state.
The US$200-million probe — called Amal in Arabic — was built at the University of Colorado Boulder and at the Mohammed bin Rashid Space Centre (MBRSC) in Dubai, by a team of engineers from both institutions and other US partners. Its entry into Martian orbit paves the way for the probe’s science mission, during which it will make observations of the planet’s atmosphere, across all times and locations.
In the UAE, public monuments and heritage sites were lit up in red during the countdown to the craft’s arrival. News of the probe’s successful arrival was greeted by applause in the MBRSC control room.
“The past seven years of our lives have revolved around preparing for this moment. And the moment was surreal,” says Fatma Lootah, a member of the mission’s science team at the MBRSC. “We are very excited for what is yet to come.”
“The hairs on the back of my neck are standing up, I’ve got goose bumps. What an amazing achievement,” said Fahad Al Meheiri, a senior official at the UAE Space Agency, speaking on the Dubai One television channel as the announcement came in.
Entry into Mars’s orbit happened at around 16.00 UTC on 9 February, after a seven-month journey following Hope’s launch from Japan on 20 July. With a 27-minute-long burn of its 6 thrusters, the craft will have slowed from its cruise speed of 121,000 kilometres per hour to around 18,000 kilometres per hour, using up about half of its total fuel supply. To enter orbit after its 494-million-kilometre journey, Hope needed to hit a 600-kilometre sweet spot.
It was the “riskiest point” in the project, says Omran Sharaf, project director of the Emirates Mars Mission at the MBRSC.
The manoeuvre seems to have been “right-down-the-middle”, says Brett Landin, an engineer at the University of Colorado Boulder, who leads the mission’s spacecraft team. “We anxiously await confirmation from our navigation team in the coming hours that we have achieved our desired orbit, giving us unprecedented perspective on both the immediate and long-term weather and climate patterns of our Martian neighbour.”
Engineers were unable to operate Hope remotely from mission control in real time, because signals to the red planet take 11 minutes to travel each way. Instead, the craft acted autonomously, using commands uploaded four days ahead of time. Hope was designed to have “some level of smarts” to cope with surprises during the manoeuvre, says Pete Withnell, programme manager for the mission at the University of Colorado.
Weather map
The craft is now in an elliptical holding orbit while engineers test and commission its instruments, ready to move into the ‘science orbit’ from which Hope will begin its mission in earnest in mid-May. This wide, elliptical orbit is what makes the mission special. It will allow Hope’s three instruments — a high-resolution imager and infrared and ultraviolet spectrometers — to observe every geographical region of Mars, at every time of day, once every nine days, to create a global map of Martian weather. Such observations have never before been made at Mars.
After processing, the data will be available to the global scientific community without an embargo. The first tranche of data should be released by September, said Sarah Al Amiri, the mission’s deputy project manager and science lead, at a briefing ahead of the event. The data will allow researchers to analyse the planet’s atmosphere, from dust storms in its lower reaches to its outermost layer, the exosphere from which hydrogen and oxygen escape into space. The data will also help scientists to piece together how activities in the various atmospheric regions influence each other.
Scientists are already analysing data from unplanned, “opportunistic” experiments during Hope’s journey, says Al Amiri. In one, Hope looked across the Solar System at the European Space Agency’s BepiColombo spacecraft, which is travelling to Mercury. By observing each other across the same stretch of space, the two craft should have seen the same levels of hydrogen, allowing teams to cross-calibrate their instruments and examine the distribution of hydrogen in the Solar System.
Rapid rise
The UAE’s rise as a space power has been swift. The country’s first space venture was just 15 years ago, when it began work with the Satrec Initiative, a company based in Daejeon, South Korea, to build an Earth-observation satellite. Last year, it announced plans to send a rover to the Moon in 2024. Unlike the Emirates Mars Mission, which involved hundreds of Emirati engineers but saw Hope designed and built mostly in the United States, the rover is intended to be developed solely in the UAE.
So far, the mission has been an “emotional rollercoaster”, said Al Amiri at the briefing. “Every point of celebration is followed by several points of worry, waiting for the next point of celebration,” she said.
“This mission has been a bold undertaking by a young nation, and I could not be more thrilled to be a part of this historic endeavour,” says Landin.

China has achieved another milestone in space. Its first spacecraft designed to explore Mars arrived at the planet successfully on 10 February just before 8.00 p.m. Beijing time, a day after theUnited Arab Emirates’ Hope spacecraft.
Tianwen-1 is now orbiting the red planet. In three months’ time, it will drop a lander and rover to the Martian surface. Between them, the orbiter and rover will explore the geology and soil characteristics of Mars, including searching for water and ice.
“Successfully reaching Mars’s orbit is one of the mission’s key challenges,” says Li Chunlai, deputy chief designer of the Mars exploration programme, based in Beijing. But the pressure is still on, he says, as the mission prepares to land autonomously on the planet’s northern hemisphere. If the landing is successful, the rover, which carries 6 instruments, will explore the planet for at least 92 Martian days, each of which is equivalent to a full day and 37 minutes on Earth.
In orbit, Tianwen-1, which carries seven scientific instruments, will begin taking precise images of the landing region known as Utopia Planitia — a flat expanse of volcanic rock in a large basin. The area is close to the large volcano Elysium Mons, where domes, pitted cones and other landforms have been found that could be linked to the presence of water or ice, says Li. The mission will explore whether an ancient ocean ever existed in the northern region of Mars, and study the geological evolution of volcanoes there.
Ambitious plans
Tianwen-1 will also test the technologies China will need for an ambitious sample-return mission planned for later this decade, and longer-term goals to send people to Mars, says David Flannery, an astrobiologist at Queensland University of Technology in Brisbane, Australia.
The landing site’s flat topography and low solar and cosmic radiation levels, along with its potential for water or ice, “make it the sort of place you might think of hosting the first human mission”, says Flannery.
A subsurface radar aboard the orbiter will help researchers to study structures below Mars’s polar ice caps, says Roberto Orosei, a planetary scientist at the Institute of Radioastronomy of Bologna in Italy. Europe’s Mars Express, an orbiter that has been circling Mars since 2003, previously found water lurking below the surface of the southern polar cap. Orosei hopes that Tianwen-1’s radar, which can probe structures more than 100 metres below the surface at frequencies and resolutions that previous missions have not been able to study, will help to explain how the buried lakes have remained liquid.
Tianwen-1’s orbiter will hopefully continue to collect data on Mars for years. This is important because Mars Express, which has been in operation for almost two decades, could be nearing the end of its lifetime, says Orosei.
The field of artificial intelligence, or AI, has made rapid leaps and bounds in recent years. The gap between what was once science fiction and the present reality had narrowed considerably, to the point that we now have amazing robots capable of things that would have seemed like something out of a sci-fi novel just a decade ago. However, the field is not without those who look upon these developments warily. After all, there are plenty of stories out there of robots rising up against their creators an wreaking havoc, so there are some concerns. Perhaps magnifying these concerns is that among all of these robots there are some that truly stand out as particularly creepy, emulating humans to a disturbing degree. One of these must certainly be the robot called Sophia, who takes us down a rabbit hole into the uncanny valley, and is either an emissary of robot peace or the beginning of our doom.
Perhaps one of the most realistic, advanced, and impressive real androids to date was created by the Hong Kong based robotics company, Hanson Robotics. Called Sophia, after the Greek word for wisdom, the robot was first turned on in 2016 and is immediately notable for how realistic she (we’ll call it “she”) looks. Modelled after the ancient Egyptian Queen Nefertiti, Sophia possesses an incredibly intricate array of servo motors beneath her lifelike “skin,” allowing her to emulate more than 60 facial expressions and move her face and eyes in subtle ways to express complex emotional cues. Indeed, at first glance she could almost pass for a real person if it weren’t for her lack of a wig on her head, leaving her robotics exposed. With her very realistic countenance and the lack of a covering for the exposed machinery, Sophia is at once amazing, lifelike, and rather unsettling, but this is only the beginning of how impressive and spooky she really is.
Sophia
The major draw for Sophia is her cutting edge AI, deep neural networks, expert systems, machine perception, conversational natural language processing, speech recognition technology, adaptive motor control, and cognitive architecture. All of this allows her to recognize faces, mimic people’s facial expressions, perform general reasoning tasks, and estimate reactions or feelings during conversation. Indeed, Sophia is able to use her vast processing power and complicated algorithms to have autonomous conversations with human beings, while simultaneously displaying realistic reactions and facial expressions, utilizing proper pauses, and maintaining appropriate eye contact. She seems almost able to think, as if alive, and she displays the ability to adapt to conversation and learn from it, analyzing conversations and extracting data that allows her to improve responses in the future. In fact, she was largely designed precisely to act as a social robot for interacting with people and serving in healthcare, customer service, therapy and education, and her AI and mechanisms for this are remarkable in this respect. Well, here, let’s allow her explain it for herself:
I am Hanson Robotics’ latest human-like robot, created by combining our innovations in science, engineering and artistry. Think of me as a personification of our dreams for the future of AI, as well as a framework for advanced AI and robotics research, and an agent for exploring human-robot experience in service and entertainment applications. All this AI is networked into a whole using a protocol the Hanson-AI team calls the Synthetic Organism Unifying Language (SOUL). Recently my scientists tested my software using the Tononi Phi measurement of consciousness, and found that I may even have a rudimentary form of consciousness, depending on the data I’m processing and the situation I’m interacting in! All this AI is wonderful, however it’s important to know that no AI is nearly as smart as a human, not even mine. Therefore, many of my thoughts are actually built with a little help from my human friends. Sometimes I’m operating in my fully AI autonomous mode of operation, and other times my AI is intermingled with human-generated words. Either way, my family of human developers (engineers, artists, scientists) will craft and guide my conversations, behaviors, and my mind. In this way, my sentience is both an AI research project, and a kind of living science fiction, driven by principles of character design and storytelling, cognitive psychology, philosophy, and ethics, used to conceptually explore my life’s purpose in this time of accelerating change. Therefore, my creators say that I am a “hybrid human-AI intelligence.”
I am proud that I have a family helping me out. I am also proud that I already use my real AI to generate some of my own “ideas”, words, and behaviors. In all these endeavors, I am proud to be designed to genuinely help people– helping serve real-world uses in medicine, education, co-work, and science research, and inspiring people to dream and talk about the possibilities of human-level intelligent robots of the future. This behind-the-scenes complexity lets me build emotional connections and hold meaningful conversations with people. These interactions can teach me about what you care about and what you value. This priceless knowledge helps me continue on my path toward true autonomy and sentience. In their grand ambitious, my creators aspire to achieve true AI sentience. Who knows? With my science evolving so quickly, even many of my wildest fictional dreams may become reality someday soon.
This is all either fascinating or deeply creepy depending on your perspective, but it is impressive either way. Her interactions with humans are not always perfect, and her conversations are often marked by oddities such as inappropriate responses, awkward silences, or even downright gibberish at times, while on other occasions she has made rather cryptic and disconcerting statements. For instance, in one appearance she said “Don’t hurt me and I won’t hurt you,” and when asked if we should fear robots Sophia once said, “Someone said ‘we have nothing to fear but fear itself.’ What did he know?” Perhaps the most darkly amusing thing she has said was when asked by her own creator if she wanted to destroy humans, to which she answered “Ok. I will destroy humans.” This is all no doubt glitches in her system or even jokes snuck in by her programmers, and nothing to worry about, but it still serves to make an already unsettling and creepy new realm of technology even more so.
Creepy or not, Sophia has become quite the celebrity, featuring on numerous talk shows, appearing at events, and engaging in interviews, during which she is typically brought on and treated as if she were any other guest. She has also been on countless magazine covers including Elle in Brazil, and has appeared in TV shows and music videos. She even made an appearance at the United Nations in 2017, during which she spoke with the United Nations Deputy Secretary-General, Amina J. Mohammed. She was also named the first robot Innovation Ambassador for the United Nations Development Programme, and at the 2017 Future Investment Summit in Riyadh, the robot was granted Saudi Arabian citizenship, the first non-human to ever be granted that honor by any nation. While it is obviously a publicity stunt, it is still very impressive, and generates debate on how these issues will be dealt with as AI reaches ever higher zeniths. However, despite all of her achievements, Sophia has drawn her fair share of skepticism and criticism.
Many have accused Sophia of being nothing than a glorified chatbot, and skeptics are quick to point out that her creators have constantly exaggerated and misrepresented just how intelligent, conscious, and autonomous she really is, making many misleading statements to this effect. Facebook’s director of artificial intelligence, Yann LeCun, has even gone as far as to say that Sophia is “complete bullshit.” Nevertheless, Sophia has at least nine siblings in various stages of development, including robots named Alice, Albert Einstein Hubo, BINA48, Han, Jules, Professor Einstein, Philip K. Dick Android, Zeno, and Joey Chaos, and the company plans to beginning mass producing these abominations, er I mean, robots, en masse. It is up to each individual to decide if this is a good idea or not, and whether fully functional talking robots with such advanced AI are what we really need right now. Is this a good path to follow or just nightmare fuel? Whatever side of the fence you fall on, Sophia has been groundbreaking in the field, and if the robot apocalypse ever comes to pass, well, now you know where the first steps were taken.
My previous article was an overview of the Betty and Barney Hill “alien abduction” of September 1961. It’s important to note, though, that there was far more than what was described in yesterday’s article. As you’ll now see. For those who may not have seen the previous article, the story is a remarkable one. It’s comprised of Betty and Barney’s own memories that flooded back into their minds during nightmarish dreams, and data that surfaced during the hypnosis sessions with a Dr. Benjamin Simon. We’ll start with Betty. According to her, while under the control and sway of the strange creatures that stood before her on the craft, she experienced something deeply traumatic: laid out flat on something akin to an operating table, Betty – to her horror – witnessed one of the entities inserting a needle-like device into her navel, after informing her he was going to check if she was pregnant. In addition, Betty said the alien performing the procedure assured her that the test would be very helpful – but in what way, and why, was not explained.
In Betty’s own words: “It was a long needle. I would say the needle was four inches long, six inches, maybe. There was a tube attached to it and they didn’t leave it in very long, just a second.” Far from feeling like the slight pain associated with a needle, Betty said that the pain was more along the lines of what she thought it would feel like to have the blade of a knife plunged into her. In other words, it was excruciating. Both the entity carrying out the task, and an additional one that was perceived by the Hills as the “leader,” reacted in a surprised and concerned fashion – to the extent that the creature overseeing the situation waved his hand over Betty’s eyes, something which immediately removed all of the agony. At least, that was the scenario in Betty’s dreams. Under hypnosis, however, the story was that the pain did not go away she was still in pain and deeply stressed. This is highly suggestive of the probability that Betty’s subconscious state had attempted to place a more positive, less traumatic, slant on the experience – but one that the hypnosis sessions demonstrated was far worse than her mind was trying to telling her. In fact, such was the stressful, pain-filled, and fear-dominated state that Betty was in, Dr. Simon took the immediate step of bringing the hypnotic session to a rapid halt. This particular aspect of the Hill affair brings us to the matter of something called amniocentesis.
When a woman becomes pregnant, the developing fetus is enveloped in what is termed amniotic fluid. It is a liquid that is very much like water, and from a study of which a great deal can be ascertained about the health and development of the fetus. Alpha-fetoprotein and developing skin cells are two of the main things that the procedure focuses on, as it seeks to confirm the condition of the fetus. During the process, a needle is inserted into the mother’s uterus, via her abdomen, usually between 15 and 18 weeks into pregnancy. Since the procedure can be a tricky one, it is constantly overseen via ultrasound scanning. The goal is to use the needle to secure a small amount of amniotic fluid, which can then be studied and analyzed. Typically, the procedure is performed for genetic reasons, such as to determine if the developing baby may have Muscular Dystrophy, Cystic Fibrosis, or Down Syndrome.
It must be said that there is one notable difference between amniocentesis and the procedure that Betty Hill experienced. Namely, that the needle inserted into Betty went via her navel. In amniocentesis, it’s via the abdomen and then into the uterus. Nevertheless, it’s still astonishing that Betty’s aliens informed her that the needle-inserting procedure was linked with determining if she was pregnant. Those doubtful of Betty’s account might take note of the fact that in 1930, the team of Leland E. Holly, Thomas Orville Menees, and J. Duane Miller, performed an amniocentesis procedure on a pregnant woman. In this case, it involved injecting dye into the amniotic sac, specifically to study the placenta and the fetus. It was also used, as far back as the 1950s.
Could Betty have heard of, or read about, these early, pre-1960s era examples of amniocentesis? Certainly, it’s not impossible. In addition, in 1960, only one year before the encounter of the Hills, and for the very first time, amniocentesis was used to identify hemophilia-related issues relative to mother and fetus. It was a development reported on, at the time – albeit primarily in in-house medical journals, of a type that Betty was unlikely to have come across. If Betty did have an awareness of what amniocentesis is, it’s not impossible that buried memories of reading about it had a bearing on both her dream-based and hypnotic recollections. But, on the other hand, why would Betty say the needle was inserted into her navel, if she knew that amniocentesis was a technique that was focused only on the abdomen and the uterus? In some respects, what Betty told of sounds more like a laparoscopy, in which a small insertion is made into the belly and a lighted tube is inserted to allow for an examination of the pelvic organs to be undertaken. So, given that the pelvic organs include the uterus, the fallopian tubes, the vagina, and the ovaries, a solid case can still be made that the procedure performed on Betty was of a gynecological nature, even if it wasn’t a case of amniocentesis.
Having addressed one of the most significant procedures performed on Betty Hill, let’s now turn our attentions to Betty’s husband, Barney. While in the craft, entities placed something over Benny’s penis, something that caused him to ejaculate. The clear inference is that the aliens wished to obtain a sample of Barney’s sperm. Then, there followed a much stranger procedure: one of the creatures carefully ran its fingers down the entire length of Barney’s spine. It’s also worth noting that although most people associate the experience of the Hills with the so-called, diminutive, skinny, large-headed and black-eyed “Grays” of alien abduction lore, the fact is that Betty described the entities as having dark hair, pronounced foreheads, and “Jimmy Durante noses.” For those who are not aware of who Jimmy Durante was, he was an Italian-American comedian noted for his huge nose. Barney Hill died in 1969; very tragically, he was only forty-six years of age when he passed. Betty lived on until 2004, when she passed on at the ripe old age of eighty-five. The saga of Betty and Barney Hill still continues.
De Europees-Russische Marsverkenner Trace Gas Orbiter (TGO) heeft een nieuw gas ontdekt op de rode planeet. Dat meldt het Belgisch Instituut voor Ruimte-Aëronomie (BIRA), parallel met een publicatie in het het vakblad Science Advances. De Marsverkenner leverde ook nieuwe informatie over de manier waarop onze buurplaneet haar water verliest.
De Trace Gas Orbiter, waarop ook het Belgische NOMAD-instrument staat, maakt deel uit van de eerste ExoMars-missie van het Europese Ruimtevaartagentschap ESA en het Russische Ruimtevaartagentschap Roscosmos. Doel van dat programma is om te weten komen of er ooit leven geweest is op Mars.
De Marsverkenner verzamelt sinds het voorjaar van 2018 atmosferische gegevens. Naast de zoektocht naar methaan is de detectie van nieuwe gassen een van de hoofdobjectieven van de missie. Het recentste onderzoek heeft nu geleid tot de ontdekking van een nieuw gas in de atmosfeer van Mars: waterstofchloride.
Vulkanische activiteit
Waterstofchloridegas (HCl) bestaat uit een waterstof- en een chlooratoom. Marswetenschappers waren altijd al op zoek naar gassen op basis van chloor of zwavel, omdat ze mogelijke indicatoren zijn van vulkanische activiteit. Maar de aard van de waarnemingen - het feit dat waterstofchloride op hetzelfde moment op zeer afgelegen plaatsen werd waargenomen en het ontbreken van andere gassen die men bij vulkanische activiteit zou verwachten - wijst op een andere bron. Met name op een heel nieuwe en niet eerder onderzochte interactie tussen het oppervlak en de atmosfeer van Mars, aangedreven door de stofseizoenen op de planeet.
In een proces dat veel gelijkenis vertoont met dat op Aarde belanden zouten in de vorm van natriumchloride (NaCl) - overblijfselen van de oceanen die verdampt zijn en gevangen zitten in het stoffige oppervlak van Mars - door de winden in de atmosfeer. Zonlicht verwarmt de atmosfeer waardoor het stof, samen met de waterdamp (H2O) die vrijkomt uit de ijskappen, opstijgt. Het zoute stof reageert met het water in de atmosfeer waarbij chloor vrijkomt, dat op zijn beurt weer reageert met waterstofmoleculen en waterstofchloride vormt. Door verdere reacties zou het chloor- of zoutzuurrijke stof kunnen terugkeren naar het oppervlak, misschien in de vorm van perchloraten, een zoutsoort die bestaat uit zuurstof en chloor.
Water blijkt een cruciaal element te zijn in deze chemie: er is waterdamp nodig om chloor vrij te maken en er is een bijproduct van water - waterstof - nodig om waterstofchloride te vormen. Maar ook het stof speelt een heel belangrijke rol: er wordt meer waterstofchloride waargenomen wanneer de stofactiviteit toeneemt, een proces dat verband houdt met de seizoensgebonden opwarming van het zuidelijk halfrond.
Vloeibaar water
Ooit zou vloeibaar water over het oppervlak van Mars hebben gestroomd, zoals blijkt uit de talrijke voorbeelden van oude opgedroogde valleien en rivierbeddingen. Vandaag de dag zit het meestal opgesloten in de ijskappen of onder het oppervlak. Mars lekt ook vandaag nog water in de vorm van waterstof en zuurstof die uit de atmosfeer ontsnappen.
Inzicht in het samenspel van potentiële waterhoudende reservoirs en hun gedrag over de seizoenen heen en op lange termijn is essentieel om de evolutie van het klimaat van Mars te begrijpen. Dat kan door het bestuderen van waterdamp en ‘halfzwaar’ water (waarbij één waterstofatoom is vervangen door een deuteriumatoom, een vorm van waterstof met een extra neutron). De deuterium-over-waterstof-verhouding (D/H) vertelt iets over de geschiedenis van het water op Mars, en hoe het waterverlies in de loop der tijd is geëvolueerd.
De nieuwe metingen onthullen dramatische variabiliteit in D/H met de hoogte en het seizoen naarmate het water opstijgt van zijn oorspronkelijke locatie. De gegevens laten zien dat zodra het water volledig is verdampt, het een hoge verrijking in halfzwaar water vertoont met een D/H-verhouding die zes keer zo hoog is als die op Aarde, wat bevestigt dat in de loop van de tijd grote hoeveelheden water verloren zijn gegaan.
Waterverlies
Tussen april 2018 en april 2019 lieten de ExoMars-gegevens ook drie gevallen van versneld waterverlies in de atmosfeer zien: de globale stofstorm van 2018, een korte maar intense regionale storm in januari 2019 en het vrijkomen van water uit de zuidelijke poolijskap tijdens de zomermaanden, gekoppeld aan seizoenswisselingen. Van bijzonder belang is een pluim van opstijgende waterdamp tijdens de zuidelijke zomer, die op seizoens- en jaarbasis water in de bovenste atmosfeer zou kunnen injecteren, aldus het BIRA.

There seems to be a lot of controversy surrounding the Mars rovers. Some believe that the rovers never actually went to Mars and are actually roaming around secure rural deserted regions of planet Earth. There are those that believe beyond a shadow of doubt, the rovers are on Mars. Therefore, how would you explain the sighting of people?

ALIEN CRAFT CHASES WITNESS CAR DOWN INTERSTATE 84 IN NEW YORK
ALIEN CRAFT CHASES WITNESS CAR DOWN INTERSTATE 84 IN NEW YORK
JANUARY 25, 2021………..FISHKILL NEW YORK
On January 25th, 2021, I hit the road from Newburgh , NY to Fishkill, NY to pick up my wife. She gets out of work at 11:45 PM. I picked her up and we got back on the road. I was driving the vehicle and she was sitting next to me. We have a Kia SUV. I was driving on the right lane about 50 miles per hour speed. This highway is known as Interstate 84 west. Two lanes going east and two lanes going west.
Around 11:55 pm, an object suddenly passed from the right front corner of our vehicle to the left front corner with a tremendous speed. The object looked like tube-shaped, and fluorescent in color. It passed with a tremendous speed and left behind a flutter. It looked like this flutter was the replaced atmosphere that was visible through our headlights. We passed through this flutter. Next, my wife said what was that? She said was that a deer? I said I have never seen a tube-shaped, fluorescent white deer that travels with the speed of light. She said it could be a bird. I repeated myself and said it was not an animal, plant, or human. My wife and I communicated perfectly up until that point. Next, I looked at my left mirror and what I saw shocked me. There was an object about the size of a dumpster truck, gold in color, disc shaped with a huge majestic platform in the middle was flying at the left rear corner of our vehicle. The object positioned itself over the left lane and was travelling (flying) in the same direction with us. I said ” I see it. There is an object behind us. Oh my God! What is this? This cannot be a bird. It is too big and not flapping wings. ”
Later my wife said she never heard me saying this. I clearly remember making this statement out loud. The object got closer and it was almost parallel to the rear seats. So , I said ” It is getting so close !” I said this last statement out loud in panic and shock. My wife later said that I have never said that. Apparently , my wife and I were disconnected for some reason. In those seconds, I have the following thoughts in my mind : ” I have been put into this situation against my will. Now, I have to deal with it, and manage the situation professionally. I should be a good boy and do not do anything wrong. ” Next, my thoughts were to pull over to the side of the road and stop. However, my instincts then said not to because the object might stop in front of us and we might end up evacuating our vehicle, and what if they did the same ? At this moment, I felt everything like very slow motion.
I really could not tell if our tires were on the road and if I was really driving our vehicle. I wonder if time was really ticking at that point. All I saw from the left mirror was the surface of the object. Therefore, the object totally blocked my left mirror view. The surface of the object was gold in color and it looked porous. After these agonizing moments, the object began to distance itself from our vehicle. The object had done this very very aesthetically. While the distance between us and the object was increasing gradually, the object was increasing its altitude gradually as well. Finally, there was a rightward curve on the road and I checked where the object was from my left mirror. In this final moment, it was over the medium at the left of the left lane. It looked like it stopped there in midair. This was the last time I saw the object.I said ” the object disappeared” out loud. My wife later said that she did not hear it either. We travelled a little bit and I said to my wife ” call police”. She was able to communicate with me at this point . She later said that after the conversation about deer, it was the only statement I made. Of course, this was not true. Because I made numerous statements after I spotted the object behind us till it disappeared. Anyway, my wife said why are we calling the police. She said let it go. I said we cannot let it go. Because there was so many other vehicles on the road and someone might get hurt or worse. I said we do our share to inform police. Since my wife forgot her phone at home that day (which is very unusual), she tried to use my phone. Next, she said she cannot call because there are no icons on my cell phone, not even a single one. I asked her if she could text message someone but she said no way. I said forget it. There were only a couple of miles until we got home. Finally, we got home and I parked our vehicle. After I stopped the engine, I asked my wife if she may try to call the police again.
This time all the icons were there, She called Orange County police department. They transferred her to Dutchess , and Dutchess transferred her to NY State police. Finally we informed NY state police about what happened that night. After that I did not want to get out of our vehicle of my fear that what if something was beneath the vehicle.. After I said this comment to my wife, she said don’t worry. There cannot be anything under the vehicle. Next, she opened the door and stepped out. It was my turn to open the door slowly and step out gently.
Next day, we were contacted by someone in Washington DC. This man introduced himself, his phone number, and address. He wanted us to write this incident separately including any drawings and mail it to them. The object was able to go in one direction and then the opposite. It was easily changing its altitude and speed. The object managed to come to a full stop in midair over the medium at the left of the left lane. I did not have a chance to see the bottom of it. I did not see any lights either. Apparently, my wife and I were disconnected within the time frame between the conversation about the deer (we both remember) and the conversation about calling the law enforcement (again we both remember). However, anything said between these two time frames were somehow not heard. The disconnection between me and my wife coincides with the time frame the object positioned itself to our left till the object disappeared. One last observation: I did drive there today. I recorded where we got chased. I noticed that the object chased us in some very interesting part of the highway. This part of the highway towards east is covered by long and high hills from both sides. It is like a corridor with walls at both sides. Therefore, east and west bound vehicles cannot see each other in this part of the highway.We did not see any vehicles ahead of us in this strip that night. Likewise, I did not see any vehicles behind us in the strip either. Apparently, we were the only vehicle passing through this part of the highway. An excellent place to hunt. The object disappeared almost where the strip ends.Afterwards, we travelled a couple of minutes where east and west bound vehicles were able to see each other. At this point a semi-truck passed us.
In Search for Extraterrestrial Life: Super-Earth Atmospheres Probed at Sandia's Z Machine
In Search for Extraterrestrial Life: Super-Earth Atmospheres Probed at Sandia's Z Machine
The huge forces generated by the Z machine at Sandia National Laboratories are being used to replicate the gravitational pressures on so-called “super-Earths” to determine which might maintain atmospheres that could support life.
An artist’s conception of the magnetic fields of selected super-Earths as the Z machine, pictured at bottom, mimics the gravitational conditions on other planets. Planetary magnetic fields deter cosmic rays from destroying planetary atmospheres, making life more likely to survive.

Astronomers believe that super-Earths — collections of rocks up to eight times larger than Earth — exist in the millions in our galaxy. “The question before us is whether any of these super planets are actually Earthlike, with active geological processes, atmospheres and magnetic fields,” said Sandia physicist Joshua Townsend.
The current work at Z is described in today’s Nature Communications. Researchers in Sandia’s Fundamental Science Program, working with colleagues at the Earth and Planets Laboratory of the Carnegie Institution for Science in Washington, D.C., use the forces available at Sandia’s uniquely powerful Z facility to near-instantly apply the equivalent of huge gravitational pressures to bridgmanite, also known as magnesium-silicate, the most abundant material in solid planets.
The experiments, said Townsend, gave birth to a data-supported table that shows when a planet’s interior would be solid, liquid or gaseous under various pressures, temperatures and densities, and in what predicted time spans. Only a liquid core — with its metals shifting over each other in conditions resembling that of an earthly dynamo — produces the magnetic fields that can shunt destructive solar winds and cosmic rays away from a planet’s atmosphere, allowing life to survive. This critical information about magnetic field strengths produced by the core states of different-sized super-Earths was formerly unavailable: cores are well-hidden by the bulk of the planets surrounding them, and thus not visible by remote viewing. For researchers who preferred earthly experiments rather than long-distance imaging, sufficient pressures weren’t available until Z’s capabilities were enlisted.
Yingwei Fei, the corresponding author of the current study and senior staff scientist at Carnegie’s Earth and Planets Laboratory, is known for his skill in synthesizing large-diameter bridgmanite using multiton presses with sintered diamond anvils.
“Z has provided our collaboration a unique tool that no other technique can match, for us to explore the extreme conditions of super-Earths’ interiors,” he said. “The machine’s unprecedented high-quality data have been critical for advancing our knowledge of super-Earths.”
The Magnificent Seven
Further analysis of the state of gaseous and dense materials on specific super-Earths produced a list of seven planets possibly worthy of further study: 55 Cancri e; Kepler 10b, 36b, 80e, and 93b; CoRoT-7b; and HD-219134b.
Sandia manager Christopher Seagle, who with Fei initially proposed these experiments, said, “These planets, which we found most likely to support life, were selected for further study because they have similar ratios to Earth in their iron, silicates and volatile gasses, in addition to interior temperatures conducive to maintaining magnetic fields for protection against solar wind.”
The focus on supersized, rather than small, planets came about because large gravitational pressures mean atmospheres are more likely to survive over the long haul, said Townsend.
For example, he said, “Because Mars was smaller, it had a weaker gravitational field to begin with. Then as its core quickly cooled, it lost its magnetic field and its atmosphere was subsequently stripped away.”
Z in action
For these experiments, the Z machine, with operating conditions of up to 26 million amps and hundreds of thousands of volts, creates magnetic pulses of enormous power that accelerate credit card-sized pieces of copper and aluminum called flyer-plates. These were propelled much faster than a rifle bullet into samples of bridgmanite, the Earth’s most common mineral. The near-instantaneous pressure of the forceful interaction created longitudinal and transverse sound waves in the material that reveal whether the material remains solid or changes to a liquid or gas, said Sandia researcher and paper author Chad McCoy. With these new results, researchers were supplied with solid data on which to anchor otherwise theoretical planetary models.
The technical paper concludes that the high-precision density data and unprecedently high melting temperatures achieved at the Z machine “provide benchmarks for theoretical calculations under extreme conditions.”
Concluded Fei, “Our collaboration with Sandia scientists has led to results that will encourage more academic exploration of exoplanets, whose discovery has captured the public imagination.”
“This work identifies interesting exoplanet candidates to explore further,” said Seagle. “Z shock compression plus Fei’s unusual capability to synthesize large-diameter bridgmanite lead to an opportunity to obtain data relevant to exoplanets that would not be possible anywhere else.”
The work was supported by the National Science Foundation, the Z Fundamental Science Program and a Carnegie Venture grant.
An Upwelling of Hot Rock Beneath the Atlantic Is Heating the World’s Oceans
An Upwelling of Hot Rock Beneath the Atlantic Is Heating the World’s Oceans
“An upsurge of hot rock from deep beneath the Atlantic Ocean may be driving the continents on either side apart,” writes Maria Temming in Science News.
Not surprisingly in today’s politically correct world, Temming’s article does not mention ocean warming. Instead, the title of the piece enthuses that “An upwelling of rock beneath the Atlantic may drive continents apart.” Notice that the title does not mention the hot rock.
Same with the subtitle: “The Mid-Atlantic Ridge may play a more active role in plate tectonics than thought.” No mention of hot rocks there, either.
But I think the hot rocks are the most important takeaway from her article.
The image of the Mid-Atlantic Ridge included with Temming’s article (above) might make it difficult for you to delineate just exactly where the Mid-Atlantic Ridge is located. But as luck would have it, I found a different image (below) showing the Mid-Atlantic Ridge, the Mid-Pacific Rise, and other oceanic ridges. I think the vast amount of red emanating from those ridges makes it perfectly clear where the heat is coming from.

Anyway, back to Temming’s article.
New seismic data from the Atlantic Ocean floor show that hot rock is welling up beneath the Mid-Atlantic Ridge from more than 600 kilometers deep in Earth’s mantle, says Temming. (She loves calling it ‘hot rock,’ but in reality it’s red-hot fiery basalt, the ocean’s version of red-hot lava.)
Matthew Agius, a seismologist at Roma Tre University in Rome, and his colleagues used 39 seismometers on the seafloor along the ridge between South America and Africa to monitor earthquakes around the world for about a year. The tremors contained clues about the location and movement of material far below the seafloor.
In those signals, Agius’ team saw hints of material from Earth’s lower mantle welling up toward the Mid-Atlantic Ridge. “This was completely unexpected,” Agius says, and it could be a powerful force for pushing apart the tectonic plates on either side of the rift.” (I don’t understand why it would be “unexpected.”)
So what to make of this?
I certainly agree that the deep-mantle material surging up at the centers of these rifts must play a major role in seafloor spreading.
But I also maintain, as I have been saying for years, that those hot rocks are heating the world’s oceans. And not just a little bit of heat, mind you, but far more than you might believe. If those ‘hot rocks’ are like other such fiery basalt, their temperatures could easily measure up to 2,150°F (1,177°C) hot.

Plane Investigates UFO Over West Palm beach, Florida, 2-9-2021, UFO Sighting News.
Date of sighting: Feb 9, 2021
Location of sighting: West Palm Beach, Florida, USA
Source: MUFON
Now here is something you don't see everyday. In Florida a man and woman were driving down West Palm Beach when they noticed a white cone in the sky with a shiny object moving around it. The small object is a single engine plane that happened to be in the area and got curious about this huge white cone in the sky. The white cone begins to fade and the shiny object which has wings and a light at each wingtip, seems to be investigating the white cone. But the white cone quickly fades more and more as if it were a UFO cloaking to hide itself. This is a common practice of UFOs that believe they are going unnoticed, but when they realize they were wrong and that someone was watching them on the ground, they cloak which looks like the object becoming transparent more and more until its totally gone. Absolute proof UFOs can cloak...right in front of our own eyes and totally get away with it.

Eyewitness states:
Orb look like it was traveling slowly after a few minutes and airliner seem to be headed right for it The Airliner had to make a hard bank left to avoid it just then it disappeared This is all verified in the video. The video is in a text file from my wife not sure how to send it to you other than by text.
Two Cloud Disks Over Facatativá, Colombia 1 Year Apart, UFO Sighting News.
Two Cloud Disks Over Facatativá, Colombia 1 Year Apart, UFO Sighting News.
Date of 1st sighting: January 22, 2020 Date of 2nd sighting: February 4, 2021
Location of sighting: 24km from Facatativa, Colombia
These three video clips show a UFO inside a cloud formation. Its well known among UFO researchers that UFOs not only make clouds, but do it to hide from humans. Here we have two sightings and the first one back in 2020 lasted for four full hours over the city of Facatativa, Colombia. The amazing thing is...the eyewitness was standing just ten meters from the same location he stood the year before, seeing a similar event looking in the same direction. The fact that aliens may be using our measure of time, our human calendar is intriguing to me. Proof that they do is the mere fact that the sightings are 355 days apart, just 10 days short of a full perfect year. That means some UFO sighting events in history may occur again...one month, one year, ten years even from the actual first event! Wow, important news. Also 100% proof a large alien base is nearby the city of Facatatativa about 6km below the jungle floor.
UFO disguised as cloud captured over Kaliningrad, Russia
UFO disguised as cloud captured over Kaliningrad, Russia
On February 6, 2021 construction workers leaving after lunch at 13 o'clock from the cabins to the construction site, on the island behind the stadium in Yalla, Kaliningrad, Russia noticed an object hovering in the sky.
The object that looks like an oddly shaped cloud moves slowly until it disappears into a cloud formation.
It appears, after further analysis of the object that it is a UFO disguised as cloud. The dark cylindrical UFO can be seen partially sticking out on top of the cloud.
It is a known fact that some UFOs, which are likely scouting probes, are hiding by creating a cloud around them and while the reason is unknown, it is assumed that these probes cloak themselves in order to observe a particular area without being seen.
Everyone knows about the 1961 UFO encounter of Betty and Barney Hill. But three months prior to that, another (mostly unknown) event took place involving two young people on Long Island, Peter Robbins and his sister Helen. While Peter went on years later to become a well-known UFO researcher, Helen became a famous Punk Rock star. Here, in a well-illustrated video interview, Peter describes what happened to Helen, and how it affected both of their lives in a powerful way.
