A new online portal by NASA and the Alaska Satellite Facility maps satellite radar meas-urements across North America, enabling users to track land movement since 2016 caused by earthquakes, landslides, volcanoes, and other phenomena.USGS An online tool maps measurements and enables non-experts to understand earthquakes, subsidence, landslides, and other types of land motion. NASA is collaborating with the Alaska Satellite Facility in Fairbanks to create a powerful web-based tool that will show the movement of land across North America down to less than an inch. The online portal and its underlying dataset unlock a trove of satellite radar measurements that can help…

The Vented Fly Box holds and safely transports vials containing flies and fly food. It includes environmental sensors that monitor temperature and relative humidity.NASA/Dominic Hart When it comes to helping NASA scientists better understand the effects of space travel on the human body, fruit flies are the heavyweights of experiments in weightlessness. Because humans and fruit flies share a lot of similar genetic code, they squeeze a lot of scientific value into a conveniently small, light package. Through a new Space Act Agreement between NASA and Axiom Space, the Vented Fly Box will enable fruit flies (Drosophila melanogaster) to launch aboard a SpaceX Dragon sp…

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) Earth scientist Compton J. Tucker has been elected to the National Academy of Sciences for his work creating innovative tools to track the planet’s changing vegetation from space. It’s research that has spanned nearly 50 years at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where he is a visiting scientist after retiring in March. Tucker’s research began with identifying wavelengths of light that are absorbed or reflected as plants undergo photosynthesis, and has evolved into calculating the health and productivity of vegetation over time with satellites. “I’m honored…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) What happens when the universe’s most magnetic object shines with the power of 1000 Suns in a matter of seconds? Thanks to NASA’s IXPE (Imaging X-ray Polarimetry Explorer), a mission in collaboration with ASI (Italian Space Agency), scientists are one step closer to understanding this extreme event. Magnetars are a type of young neutron star – a stellar remnant formed when a massive star reaches the end of its life and collapses in on itself, leaving behind a dense core roughly the mass of the Sun, but squashed down to the size of a city. Neutron stars display some of the most extreme p…

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) A lot can change in a year for Earth’s forests and vegetation, as springtime and rainy seasons can bring new growth, while cooling temperatures and dry weather can bring a dieback of those green colors. And now, a novel type of NASA visualization illustrates those changes in a full complement of colors as seen from space. Researchers have now gathered a complete year of PACE data to tell a story about the health of land vegetation by detecting slight variations in leaf colors. Previous missions allowed scientists to observe broad changes in chlorophyll, the pigment that gives plants th…

ESA/Hubble & NASA, C. Murray This NASA/ESA Hubble Space Telescope image features a sparkling cloudscape from one of the Milky Way’s galactic neighbors, a dwarf galaxy called the Large Magellanic Cloud. Located 160,000 light-years away in the constellations Dorado and Mensa, the Large Magellanic Cloud is the largest of the Milky Way’s many small satellite galaxies. This view of dusty gas clouds in the Large Magellanic Cloud is possible thanks to Hubble’s cameras, such as the Wide Field Camera 3 (WFC3) that collected the observations for this image. WFC3 holds a variety of filters, and each lets through specific wavelengths, or colors, of light. This image combine…

X-ray: NASA/CXC/CfA/Stroe, A. et al.; Optical: PanSTARRS; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk New observations from NASA’s Chandra X-ray Observatory and other telescopes have captured a rare cosmic event: two galaxy clusters have collided and are now poised to head back for another swipe at each other. Galaxy clusters are some of the largest structures in the Universe. Held together by gravity, they are monster-sized collections of hundreds or thousands of individual galaxies, massive amounts of superheated gas, and invisible dark matter. The galaxy cluster PSZ2 G181.06+48.47 (PSZ2 G181 for short) is about 2.8 billion light-years from Ear…

5 Min Read 3 Black Holes Caught Eating Massive Stars in NASA Data A disk of hot gas swirls around a black hole in this illustration. Some of the gas came from a star that was pulled apart by the black hole, forming the long stream of hot gas on the right, feeding into the disk. Credits: NASA/JPL-Caltech Black holes are invisible to us unless they interact with something else. Some continuously eat gas and dust, and appear to glow brightly over time as matter falls in. But other black holes secretly lie in wait for years until a star comes close enough to snack on. Scientists have recently identified three supermassi…

The core portion of NASA’s Nancy Grace Roman Space Telescope has successfully completed vibration testing, ensuring it will withstand the extreme shaking experienced during launch. Passing this key milestone brings Roman one step closer to helping answer essential questions about the role of dark energy and other cosmic mysteries. “The test could be considered as powerful as a pretty severe earthquake, but there are key differences,” said Cory Powell, the Roman lead structural analyst at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Unlike an earthquake, we sweep through our frequencies one at a time, starting with very low-level amplitudes and gradually…

NASA NASA astronaut Ed White, pilot of the Gemini IV mission, floats in space on June 3, 1965, while performing the first spacewalk by an American. As White floated outside the spacecraft, he used a Hand-Held Maneuvering Unit, informally called a “zip gun.” The device, seen in White’s right hand in this image, expelled pressurized oxygen to provide thrust for controlling his movements outside the capsule. “You look beautiful, Ed,” remarked fellow crew member astronaut James A. McDivitt, who remained inside the spacecraft, as he began taking pictures of White tumbling around outside his window. “I feel like a million dollars,” White said. “This is the greatest experi…
