Shrouded in ice in the lonely Weddell Sea, Vega Island is an eerie sight to behold. On this speck of land east of the Antarctic Peninsula, ice, rock outcrops, and glacial moraines combine to create the appearance of a smirking skull in profile looking toward Devil Island. These images show Vega Island’s creepy countenance at the start of austral autumn (left) and in spring (right). They were…
This global map of Mars shows 13 locations that match the mineralogy and chemistry of Teghaza 001, one of the most ancient Martian meteorites ever found on Earth. While scientists can never know for sure where a Martian meteorite originated, Teghaza 001 includes clues that link it to highlands in the southern hemisphere of the Red Planet. The base map of this image was produced with data from the…
This slice of Teghaza 001, one of the most ancient Martian meteorites ever found on Earth, was used to determine the age of the rock. Reflected light images like these serve as a scientist’s road map, helping them find minerals of interest to analyze by different instruments. Figure A is the same image with annotations showing minerals like iron-titanium oxides (brighter grains) and pyroxene…
When a rose-colored meteorite was found in the Sahara Desert in 2022, no one knew how old it was or where it came from. Not until NASA-funded scientists age-dated its minerals did they realize the nearly 2-pound (800-gram) rock was a piece of Mars that formed more than 4.1 billion years ago, making it one of the oldest Martian meteorites ever found. Named Teghaza 001 after the salt plain in Mali…
When companies began approaching NASA’s Langley Research Center, asking to be included in the In-Space Servicing, Assembly, and Manufacturing (ISAM) State of Play for access to competitive intelligence, the team knew they had crossed an inflection point. “We’ve had some unnamed companies ask if we have any proprietary information,” says Dale Arney, senior team lead for the ISAM Technology…
The Socialist Republic of Vietnam became the 78th nation to sign the Artemis Accords, joining a growing coalition of like-minded nations committed to the peaceful, transparent, and responsible exploration of space. “Vietnam is joining at an important point in the development of its own space program,” said NASA Deputy Administrator Matt Anderson in recorded remarks for the ceremony. “NASA and the…
The four volunteers who lived and worked in a simulated NASA Mars mission for more than a year will exit their habitat on Saturday, Oct. 31, after 378 days of isolation in a facility at the agency’s Johnson Space Center in Houston. Health and performance data collected from the simulation can help NASA develop methods to counter human spaceflight risks for future Artemis and Moon Base missions.…
When Rice University student Malvika Bhardwaj asked her mentor Daniel Cohen, a Guidance, Navigation & Control (GN&C) engineer at NASA’s Johnson Space Center, whether he had time to keep teaching interns with his busy workload, he answered, “You decide what’s important.” In honor of National Mentoring Day on Oct. 27, Bhardwaj reflects on how Cohen’s advice and support has shaped her internship…
Some Antarctic icebergs linger close to home for decades, running aground near the ice shelves that spawned them or circling partway around the continent on coastal currents. Others, like Iceberg A-81, make a faster exit, heading north out of the Weddell Sea along a route well-traveled by the region’s bergs. Fast is relative, though. After breaking from the Brunt Ice Shelf in January 2023, the…
Over 1,645 Martian days, NASA’s Perseverance Mars rover measured the fine and ultrafine Martian dust particles found clinging to samples of spacesuit materials that are carried aboard the rover, including some that are small enough to penetrate the lungs and enter the bloodstream. The findings will be published Tuesday, Oct. 27, in the Proceedings of the National Academy of Sciences and could…
NASA and the U.S. Department of Agriculture (USDA) have signed a Memorandum of Understanding expanding cooperation in Earth observation, geospatial analytics, and advanced data technologies, supporting USDA’s data modernization plan for United States agriculture. “NASA develops some of the most advanced sensing, computing, and analytical capabilities in the world, and we should put those tools to…
The Japanese tradition of momijigari , or “red leaf hunting,” stretches back more than a millennium, as evidenced by ancient poems describing journeys to admire fall foliage. In America, mentions of foliage trips began appearing in the historical record in the 19 th century, around the time artists and poets such as Frederic Church and Emily Dickinson celebrated autumn color in depictions of the…
