Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Jet Propulsion Laboratory perfected aerogel for the Stardust mission. Under Stardust, bricks of aerogel covered panels on a spacecraft that flew behind a comet, with the microporous material “soft catching” any particles that might strike it and preserving them for return to Earth.NASA Consisting of 99% air, aerogel is the world’s lightest solid. This unique material has found purpose in several forms — from NASA missions to high fashion.
Driven by the desire to create a 3D cloud, Greek artist, Ioannis Michaloudis, learned to use aerogel as an artistic medium. His journey spanning more than 25 years took him to the Massachusetts Institute of Technology (MIT) in Cambridge; Shivaji University in Maharashtra, India, and NASA’s Jet Propulsion Laboratory in Southern California.
A researcher at MIT introduced Michaloudis to aerogel after hearing of his cloud-making ambition, and he was immediately intrigued. Aerogel is made by combining a polymer with a solvent to create a gel and flash-drying it under pressure, leaving a solid filled with microscopic pores.
Scientists at JPL chose aerogel in the mid-1990s to enable the Stardust mission, with the idea that a porous surface could capture particles while flying on a probe behind a comet. Aerogel worked in lab tests, but it was difficult to manufacture consistently and needed to be made space-worthy. NASA JPL hired materials scientist Steve Jones to develop a flight-ready aerogel, and he eventually got funding for an aerogel lab.
The aerogel AirSwipe bag Michaloudis created for Coperni’s 2024 fall collection debut appears almost luminous in its model’s hand. The bag immediately captured the world’s attention.Coperni
The Stardust mission succeeded, and when Michaloudis heard of it, he reached out to JPL, where Jones invited him to the lab. Now retired, Jones recalled, “I went through the primer on aerogel with him, the different kinds you could make and their different properties.” The size of Jones’ reactor, enabling it to make large objects, impressed Michaloudis. With tips on how to safely operate a large reactor, he outfitted his own lab with one.
In India, Michaloudis learned recipes for aerogels that can be molded into large objects and don’t crack or shrink during drying. His continued work with aerogels has created an extensive art portfolio.
Michaloudis has had more than a dozen solo exhibitions. All his artwork involves aerogel, drawing attention with its unusual qualities. An ethereal, translucent blue, it casts an orange shadow and can withstand molten metals.
In 2020, Michaloudis created a quartz-encapsulated aerogel pendant for the centerpiece of that year’s collection from French jewelry house Boucheron. Michaloudis also captured the fashion and design world’s attention with a handbag made of aerogel, unveiled at Coperni’s 2024 fall collection debut.
NASA was a crucial step along the way. “I am what I am, and we made what we made thanks to the Stardust project,” said Michaloudis.

Searching for Ancient Rocks in the ‘Forlandet’ Flats
NASA’s Mars Perseverance rover acquired this image of the “Fallbreen” workspace using its onboard Left Navigation Camera (Navcam). The camera is located high on the rover’s mast and aids in driving. This image was acquired on May 22, 2025 (Sol 1512, or Martian day 1,512 of the Mars 2020 mission) at the local mean solar time of 14:39:01. NASA/JPL-Caltech Written by Henry Manelski, Ph.D. student at Purdue University
This week Perseverance continued its gradual descent into the relatively flat terrain outside of Jezero Crater. In this area, the science team expects to find rocks that could be among the oldest ever observed by the Perseverance rover — and perhaps any rover to have explored the surface of Mars — presenting a unique opportunity to understand Mars’ ancient past. Perseverance is now parked at “Fallbreen,” a light-toned bedrock exposure that the science team hopes to compare to the nearby olivine-bearing outcrop at “Copper Cove.” This could be a glimpse of the geologic unit rich in olivine and carbonate that stretches hundreds of kilometers to the west of Jezero Crater. Gaining insight into how these rocks formed could have profound implications for our constantly evolving knowledge of this region’s history. Perseverance’s recent traverses marked another notable transition. After rolling past Copper Cove, Perseverance entered the “Forlandet” quadrangle, a 1.2-square-kilometer (about 0.46 square mile, or 297-acre) area along the edge of the crater that the science team named after Forlandet National Park on the Norwegian archipelago of Svalbard. Discovered in the late 16th century by Dutch explorers, this icy set of islands captured the imagination of a generation of sailors searching for the Northwest Passage. While Perseverance is in the Forlandet quad, landforms and rock targets will be named informally after sites in and around this national park on Earth. As the rover navigates through its own narrow passes in the spirit of discovery, driving around sand dunes and breezing past buttes, we hope it channels the perseverance of the explorers who once gave these rocks their names.

After a decade of searching, NASA’s MAVEN (Mars Atmosphere Volatile Evolution) mission has, for the first time, reported a direct observation of an elusive atmospheric escape process called sputtering that could help answer longstanding questions about the history of water loss on Mars.
Scientists have known for a long time, through an abundance of evidence, that water was present on Mars’ surface billions of years ago, but are still asking the crucial question, “Where did the water go and why?”
Early on in Mars’ history, the atmosphere of the Red Planet lost its magnetic field, and its atmosphere became directly exposed to the solar wind and solar storms. As the atmosphere began to erode, liquid water was no longer stable on the surface, so much of it escaped to space. But how did this once thick atmosphere get stripped away? Sputtering could explain it.
Sputtering is an atmospheric escape process in which atoms are knocked out of the atmosphere by energetic charge particles.
“It’s like doing a cannonball in a pool,” said Shannon Curry, principal investigator of MAVEN at the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder and lead author of the study. “The cannonball, in this case, is the heavy ions crashing into the atmosphere really fast and splashing neutral atoms and molecules out.”
While scientists had previously found traces of evidence that this process was happening, they had never observed the process directly. The previous evidence came from looking at lighter and heavier isotopes of argon in the upper atmosphere of Mars. Lighter isotopes sit higher in the atmosphere than their heavier counterparts, and it was found that there were far fewer lighter isotopes than heavy argon isotopes in the Martian atmosphere. These lighter isotopes can only be removed by sputtering.
“It is like we found the ashes from a campfire,” said Curry. “But we wanted to see the actual fire, in this case sputtering, directly.”
To observe sputtering, the team needed simultaneous measurements in the right place at the right time from three instruments aboard the MAVEN spacecraft: the Solar Wind Ion Analyzer, the Magnetometer, and the Neutral Gas and Ion Mass Spectrometer. Additionally, the team needed measurements across the dayside and the nightside of the planet at low altitudes, which takes years to observe.
The combination of data from these instruments allowed scientists to make a new kind of map of sputtered argon in relation to the solar wind. This map revealed the presence of argon at high altitudes in the exact locations that the energetic particles crashed into the atmosphere and splashed out argon, showing sputtering in real time. The researchers also found that this process is happening at a rate four times higher than previously predicted and that this rate increases during solar storms.
The direct observation of sputtering confirms that the process was a primary source of atmospheric loss in Mars’ early history when the Sun’s activity was much stronger.
“These results establish sputtering’s role in the loss of Mars’ atmosphere and in determining the history of water on Mars,” said Curry.
The finding, published this week in Science Advances, is critical to scientists’ understanding of the conditions that allowed liquid water to exist on the Martian surface, and the implications that it has for habitability billions of years ago.
The MAVEN mission is part of NASA’s Mars Exploration Program portfolio. MAVEN’s principal investigator is based at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder, which is also responsible for managing science operations and public outreach and communications. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the MAVEN mission. Lockheed Martin Space built the spacecraft and is responsible for mission operations. NASA’s Jet Propulsion Laboratory in Southern California provides navigation and Deep Space Network support.

What would you do if you suddenly felt an unseen presence, turned around—and found yourself face to face with a seven-foot-tall, insect-like entity? Since 2006, anglers along New Jersey’s Musconetcong River have reported startling encounters with just such a being: a towering, humanoid creature that closely resembles a praying mantis.
But these aren’t just fleeting sightings. Witnesses frequently describe deeply unsettling experiences: telepathic communication, a sense of their thoughts or memories being accessed, and profound physiological effects. Consistent patterns emerge—electronic devices glitch, the surrounding forest falls unnaturally silent, and a strange, low-frequency hum seems to vibrate through the air.
More intriguingly, these mantis-like figures aren’t limited to modern encounters. Strikingly similar forms appear in ancient art across the globe, from 8,000-year-old cave paintings to references in Egyptian iconography. Could these entities have been with us since the dawn of civilization?
Theories vary widely. Some suggest these beings are an advanced species of insectoid extraterrestrials, possibly master geneticists overseeing hybridization programs involving humanity. Others propose a more Earth-bound origin, perhaps they’re a secret lineage of evolved terrestrial insects, hiding in the shadows of time.
And then there’s the interdimensional hypothesis: that these creatures aren’t physical in the way we understand, but exist in a parallel state of reality, occasionally phasing into ours.
Some researchers have even speculated that geological fault lines, like those beneath the Musconetcong River, could serve as energetic gateways, allowing these entities to cross between dimensions.
One thing is clear: the Mantis beings are watching and they may have been here far longer than we’ve dared to imagine.

The Curiosity rover continues to capture fascinating anomalies on the Martian surface. In this instance, researcher Jean Ward has examined a particularly intriguing discovery: a disc-shaped object embedded in the side of a mound or hill.
The images were taken by the Curiosity rover’s Mast Camera (Mastcam) on April 30, 2025 (Sol 4526). To improve clarity, Ward meticulously removed the grid overlay from the photographs, enhancing the visibility of the object.
To provide better spatial context for the disc’s location, Ward assembled two of the images into a collage. In the composite, you can see the surrounding area including a ridge, and the small mound where the disc appears partially embedded, possibly near the entrance of an opening.
The next image offers the clearest view of the anomaly. Ward again removed the grid overlay and subtly enhanced the contrast to bring out finer details, as the original image appeared overly bright and washed out.
In the close-up, displayed at twice the original scale, the smooth arc of the disc is distinctly visible. Its texture seems unusual, resembling stone or a slab-like material, flat yet with a defined curvature.
Might this disc-like structure have been engineered as a gateway, part of a hidden entrance leading to an architectural complex embedded within the hillside, hinting at a long-forgotten subterranean stronghold once inhabited by an extraterrestrial civilization?
