Preparations for Next Moonwalk Simulations Underway (and Underwater)
Ice cover ebbs and flows through the seasons in the Arctic (left) and the Antarctic (right). Overall, ice cover has declined since scientists started tracking it half a century ago. Download this visualization from NASA’s Scientific Visualization Studio: https://svs.gsfc.nasa.gov/5099Trent Schindler/NASA’s Scientific Visualization Studio Winter sea ice cover in the Arctic was the lowest it’s ever been at its annual peak on March 22, 2025, according to NASA and the National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder. At 5.53 million square miles (14.33 million square kilometers), the maximum extent fell below the prior low of 5.56 million square miles (14.41 million square kilometers) in 2017.
In the dark and cold of winter, sea ice forms and spreads across Arctic seas. But in recent years, less new ice has been forming, and less multi-year ice has accumulated. This winter continued a downward trend scientists have observed over the past several decades. This year’s peak ice cover was 510,000 square miles (1.32 million square kilometers) below the average levels between 1981 and 2010.
In 2025, summer ice in the Antarctic retreated to 764,000 square miles (1.98 million square kilometers) on March 1, tying for the second lowest minimum extent ever recorded. That’s 30% below the 1.10 million square miles (2.84 million square kilometers) that was typical in the Antarctic prior to 2010. Sea ice extent is defined as the total area of the ocean with at least 15% ice concentration.
The reduction in ice in both polar regions has led to another milestone — the total amount of sea ice on the planet reached an all-time low. Globally, ice coverage in mid-February of this year declined by more than a million square miles (2.5 million square kilometers) from the average before 2010. Altogether, Earth is missing an area of sea ice large enough to cover the entire continental United States east of the Mississippi.
“We’re going to come into this next summer season with less ice to begin with,” said Linette Boisvert, an ice scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It doesn’t bode well for the future.”

Observations since 1978 show that ice cover has declined at both poles, leading to a downward trend in the total ice cover over the entire planet. In February 2025, global ice fell to the smallest area ever recorded. Download this visualization from NASA's Scientific Visualization Studio: https://svs.gsfc.nasa.gov/5521Mark Subbaro/NASA's Scientific Visualization Studio Scientists primarily rely on satellites in the Defense Meteorological Satellite Program, which measure Earth’s radiation in the microwave range. This natural radiation is different for open water and for sea ice — with ice cover standing out brightly in microwave-based satellite images. Microwave scanners can also penetrate through cloud cover, allowing for daily global observations. The DMSP data are augmented with historical sources, including data collected between 1978 and 1985 with the Nimbus-7 satellite that was jointly operated by NASA and the National Oceanic and Atmospheric Administration.
“It’s not yet clear whether the Southern Hemisphere has entered a new norm with perennially low ice or if the Antarctic is in a passing phase that will revert to prior levels in the years to come,” said Walt Meier, an ice scientist with NSIDC.

On the night of February 23, 2025, residents of Tucumán, Argentina witnessed an astonishing sight during a violent thunderstorm. As a powerful lightning bolt tore through the sky, it briefly illuminated a massive, cigar-shaped object hovering in the storm’s center.
Eyewitnesses described the object as dark, elongated, and solid, standing in stark contrast to the swirling storm clouds around it. Unlike a natural weather phenomenon, the shape appeared structured and deliberate, leading many to speculate that it was a UFO of intelligent design, possibly of extraterrestrial origin.
It is not clear whether the object was struck by the lightning but there have been reports of UFOs being hit by lightning yet remaining unaffected, suggesting they may either harness or withstand immense energy levels.
Some researchers believe that certain UFOs absorb energy from lightning as a means of propulsion or power generation. In past cases, similar sightings have been reported in the presence of electrical storms, further fueling theories that such crafts may recharge their systems using natural energy sources.
It is known that theoretical physics explores the concept of extracting energy from electrical phenomena, such as Tesla’s ideas about wireless energy transmission. If an advanced civilization mastered this, lightning could be a viable energy source.

On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow.
The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined.
The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size.
By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit.
A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity.
Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article

In the depths of the ocean, where countless strange fish and creatures dwell in perpetual darkness, they remain unseen, unless unexpectedly caught. This was the case during an expedition by a Russian deep-sea fisherman, who was stunned when he reeled in a bizarre creature that strikingly resembled an alien’s head.
The eerie catch was made by Roman Fedortsov during an expedition in the northern Pacific Ocean.
The fisherman shared the video of the strange creature with his followers, with viewers comparing the bulbous fish to an extraterrestrial or even Krang, the villain from Teenage Mutant Ninja Turtles.
Fisherman Fedortsov has previously made headlines thanks to other weird and wonderful catches which you can view at Dailymail.
Despite its eerie appearance, the fish was not an alien or a mutant but rather a species known as the smooth lumpsucker, a deep-sea fish recognized for its distinctive, gelatinous look.

2025 Aviation Weather Mission: Civil Air Patrol Cadets Help Scientists Study the Atmosphere with GLOBE Clouds
The Science Activation Program’s NASA Earth Science Education Collaborative (NESEC) is working alongside the Civil Air Patrol (CAP) to launch the 2025 Aviation Weather Mission. The mission will engage cadets (students ages 11-20) and senior members to collect aviation-relevant observations including airport conditions, Global Learning and Observations to Benefit the Environment (GLOBE) Cloud observations, commercial aircraft information (including registration number and altitude), and satellite collocations provided by the NASA GLOBE Clouds team at NASA Langley Research Center. This mission results from a highly successful collaboration between NESEC and CAP as cadets and senior members collected cloud, air temperature, and land cover observations during the partial and total solar eclipses in 2023 and 2024, engaging over 400 teams with over 3,000 cadets and over 1,000 senior members in every state, Washington DC, and Puerto Rico.
The 2025 Aviation Weather Mission will take place from April through July 2025, collecting observations over two 4-hour periods while practicing additional skills, such as flight tracking, orienteering, and data management. So far, over 3,000 cadets in 46 wings (states) have signed up to participate.
Science Activation recently showed support for this mission through a letter of collaboration sent to CAP Major General Regena Aye in early February. NASA GLOBE Clouds and GLOBE Observer are part of the NASA Earth Science Education Collaborative (NESEC), which is led by the Institute for Global Environmental Strategies (IGES) and supported by NASA under cooperative agreement award number NNX16AE28A. NESEC is part of NASA’s Science Activation Portfolio.
