Insights into metal alloy solidification Researchers report details of phase and structure in the solidification of metal alloys on the International Space Station, including formation of microstructures. Because these microstructures determine a material’s mechanical properties, this work could support improvements in techniques for producing coatings and additive manufacturing or 3D printing processes. METCOMP, an ESA (European Space Agency) investigation, studied solidification in microgravity using transparent organic mixtures as stand-ins for metal alloys. Conducting the research in microgravity removed the influence of convection and other effects of gravity. Results help scientists…

Hubble Telescope spies newborn stars in famous Orion Nebula (photo)

NeRD

Two young stars shine bright in the dusty depths of the Orion Nebula in a new Hubble Space Telescope image. Located about 1,300 light-years from Earth, these young stars, also known as protostars, reside in a hotbed for star formation: the Orion Nebula, which is the nearest massive star-forming region to Earth and is home to hundreds of newborn stars. The recent photo from the Hubble Space Telescope captures two of these protostars, called HOPS 150 and HOPS 153, both of which take their names from the Herschel Orion Protostar…

Space Force to march in Trump’s Jan. 20 inauguration, a 1st for the new military branch

NeRD

On Monday (Jan. 20), the U.S. Space Force will participate in a presidential inauguration for the first time. Representing the military branch will be 45 Guardians, the official name for U.S. Space Force personnel, who work in a wide range of careers across the country. The 45 Guardians, who are volunteers, recently arrived at Joint Base Anacostia-Bolling, a large military installation in Washington, D.C., where they’ve been practicing drills for Monday’s inauguration of President-elect Donald Trump. They’ve come together with the Space Force Honor Guard, which was founded 17 months…

Centuries-old supernova guides James Webb Space Telescope through an interstellar gap

NeRD

The spaces between stars in our galaxy are enigmatic realms filled with vast, diffuse clouds of gas and dust. These clouds tend to remain invisible — but the James Webb Space Telescope (JWST) has managed to capture one in a rare moment when it was lit up. Peering at a dusty pocket of our galaxy about 11,000 light-years away in the constellation Cassiopeia, the James Webb Space Telescope’s powerful infrared eyes watched as light from a centuries-old supernova illuminated interstellar material, warming it and causing it to glow. “This is…

Major milestone! India becomes 4th nation to dock satellites in orbit

NeRD

India continues to prove out the abilities of its increasingly robust space program. The two satellites of the Indian Space Research Organization‘s (ISRO) Space Docking Experiment, or SpaDex, successfully met up in Earth orbit yesterday (Jan. 15), making India just the fourth country to pull off an in-space docking. The other three are all heavy hitters in the space game: the United States, Russia and China. “Spacecraft docking successfully completed! A historic moment,” ISRO said in an X post last night (Jan. 15). “Congratulations to the entire team! Congratulations to…

Astronauts repair black hole observatory, inspect cosmic ray detector on ISS spacewalk

NeRD

An X-ray observatory used to study neutron stars is “back in the black” and a cosmic ray detector is ready for possible future upgrades after two astronauts completed a spacewalk outside the International Space Station (ISS). Nick Hague worked to repair the Neutron star Interior Composition Explorer, or NICER, mounted to the outside of the space station, before he and Expedition 72 commander Suni Williams inspected the Alpha Magnetic Spectrometer (AMS) during a six-hour EVA (extravehicular activity) on Thursday (Jan. 16). Hague and Williams began the spacewalk at 8:01 a.m.…

Measurements from space support wildfire risk predictions Researchers demonstrated that data from the International Space Station’s ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument played a significant role in the ability of machine learning algorithms to predict wildfire susceptibility. This result could help support development of effective strategies for predicting, preventing, monitoring, and managing wildfires. As the frequency and severity of wildfires increases worldwide, experts need reliable models of fire susceptibility to protect public safety and support natural resource planning and risk management. ECOSTRESS measures evapotranspiration, water use…

NASA won’t decide on Mars Sample Return plan until mid-2026

NeRD

NASA is considering two ways to get its precious Mars samples back to Earth, but the agency won’t pick a winner for another 18 months or so. Analysis of those samples, which are being collected by NASA’s Perseverance rover, could reveal a wealth of data about Mars and its history — including, perhaps, whether the Red Planet has ever hosted life. NASA is therefore eager to get the Mars material — about 30 cigar-sized, sealed tubes containing rock cores and sediment — home, and then on to laboratories around the…

JAXA’s First Wooden Satellite Deploys from Space Station

NeRD

Internal view of LignoSat’s structure shows the relationship among wooden panels, aluminum frames, and stainless-steel shafts. Credit: Kyoto University In December 2024, five CubeSats deployed into Earth’s orbit from the International Space Station. Among them was LignoSat, a wooden satellite from JAXA (Japanese Aerospace Exploration Agency) that investigates the use of wood in space. Findings could offer a more sustainable alternative to conventional satellites. A previous experiment aboard station exposed three species of wood to the space environment to help researchers determine the best option for LignoSat. The final design…
