New Glenn-3 will refly the booster that landed after delivering NASA's ESCAPADE Mars probes, deploying AST SpaceMobile's 2,400-square-foot BlueBird 7 direct-to-device satellite.
The farthest Kreutz sungrazer ever discovered will pass just 161,000 kilometers above the Sun's surface on Saturday, threading the inner solar corona in a make-or-break encounter that could produce a comet visible in broad daylight or end in total disintegration.
NASA's Hubble Space Telescope caught comet C/2025 K1 fragmenting into at least four pieces across three days, marking the closest-to-breakup observation in the telescope's history.
Using the upgraded GRAVITY+ instrument on the ESO's Very Large Telescope Interferometer, researchers have directly detected a second protoplanet forming in the disk around the young star WISPIT 2, located 437 light-years from Earth.
Scientists have detected all five canonical nucleobases in pristine samples from asteroid Ryugu, the first confirmation of a complete set of DNA and RNA building blocks in material collected directly from space.
NASA's Perseverance rover gains autonomous navigation and AI-planned driving while the ESCAPADE twin spacecraft head for Mars orbit, but Congress's cancellation of Mars Sample Return hands the prize of returning Martian rocks to China's Tianwen-3 mission.
Three separate satellite programs are converging in 2026 to transform wildfire detection from space, while university researchers benchmark AI models that could process the flood of new orbital data.
SpaceX reached 10,020 active Starlink satellites on March 17, constituting two-thirds of all active spacecraft, while NASA warns 500,000 satellites would contaminate nearly every telescope image.
NASA's James Webb Space Telescope has captured the most detailed images yet of nebula PMR 1, nicknamed the Exposed Cranium, revealing a two-light-year-wide structure shaped by jets from a massive dying star roughly 5,000 light-years away in the constellation Vela.
A University of Washington team identifies signs of a catastrophic planetary collision around star Gaia20ehk, offering the first real-time analog of the giant impact that created Earth's Moon 4.5 billion years ago.
The 1,300-pound radiation belt spacecraft burned up over the eastern Pacific Ocean on March 11, ending a 14-year journey that began with a two-year mission and yielded the discovery of a transient third radiation belt around Earth.
A team using the Hobby-Eberly Telescope processed 600 million spectra to build the first large-scale intensity map of Lyman-alpha emissions from 9 to 11 billion years ago, exposing faint galaxies and intergalactic gas invisible to conventional surveys.
