Weather permitting, NASA plans to move the Space Launch System rocket and Orion spacecraft for Artemis II off Launch Pad 39B at the agency Kennedy Space Center in Florida as soon as Tuesday, Feb 24. The integrated stack will travel back to the Vehicle Assembly Building so teams can investigate and correct an issue with helium flow to the rocket upper stage. Engineers began preparing for th

A plume of lithium pollution detected in the upper atmosphere in February 2025 has now been directly linked to the uncontrolled re-entry of a Falcon 9 rocket stage. Researchers report that this event provides the first direct measurement of upper-atmospheric contamination from disintegrating space hardware as it re-enters the atmosphere. Defunct satellites and spent rocket stages are gener

NASA's Perseverance rover can now determine its exact position on Mars without relying on ground teams, using a new system called Mars Global Localization that compares navigation camera panoramas to orbital terrain maps. Running on a powerful processor originally dedicated to the Ingenuity Mars Helicopter, the algorithm can pinpoint the rover's location to within about 25 centimeters in roughly

An international team using the Low Frequency Array has released the most detailed low frequency radio map of the sky so far, revealing 13.7 million cosmic radio sources and delivering an unprecedented census of actively growing supermassive black holes across the universe. The new LOFAR Two-metre Sky Survey Data Release 3 also showcases a remarkable variety of systems powered by these black hol

Astronomers have puzzled over why many icy worlds in the distant Kuiper Belt look like snowmen, with two round lobes joined together. New work from Michigan State University points to a surprisingly simple explanation: these so called contact binaries can form directly through gravitational collapse. Far beyond Neptune, the Kuiper Belt holds icy, largely untouched planetesimals that preser

A Northumbria University PhD student has led an international collaboration to construct the first three-dimensional view of Uranus upper atmosphere, showing how the planet's unusual magnetic field sculpts bright auroras thousands of kilometers above its clouds. Using the James Webb Space Telescope, operated by NASA with ESA and CSA, lead author Paola Tiranti and colleagues observed Uranus

NASA on Thursday blamed what it called engineering vulnerabilities in Boeing's Starliner spacecraft along with internal agency mistakes in a sharply critical report assessing a botched mission that left two astronauts stranded in space. The US space agency labeled the 2024 test flight of the Starliner capsule a "Type A" mishap - the same classification as the deadly Challenger and Columbia

AAC Clyde Space has started building two additional maritime data satellites, Sedna-3 and Sedna-4, to expand capacity in its established space-based maritime data services. The company has placed orders for key components and assigned the build to its U.S. subsidiary AAC SpaceQuest, aiming to support continuity of service and improve performance as its fleet renews

OpenAI has hired the Austrian creator of OpenClaw, an artificial intelligence tool able to execute real-world tasks, the US startup's head Sam Altman said on Sunday. AI agent tool OpenClaw has fascinated - and spooked - the tech world since researcher Peter Steinberger built it in November to help organise his digital life. A Reddit-like pseudo social network for OpenClaw agents called
