NASA's SPHEREx observatory is now in space for a two year year mission to create a 3D map of the entire celestial sky. The telescope left the ground on top of a Falcon 9 rocket from a launch pad in California, four years after NASA announced that a SpaceX flight will launch the mission, along with NASA's PUNCH (Polarimeter to Unify the Corona and Heliosphere) microsatellites. SPHEREx separated from SpaceX's vehicle at 12AM Eastern time on March 12 and will remain in low Earth orbit, where it will maintain a position relative to the sun that will remain the same throughout the year.<br /> View of @NASA's SPHEREx and Earth shortly after deployment pic.twitter.com/TT2pyVX43Q— SpaceX (@SpaceX) March 12, 2025<br /> <br /> <br /> <br /> Every [...]
At the start of the month, Elon Musk announced that two of his companies — SpaceX and xAI — were merging, and would jointly launch a constellation of 1 million satellites to operate as orbital d [...]
A space observatory designed to map the entire sky over a period of two years to further our understanding of the early universe has started snapping images. SPHEREx, which launched in early March, go [...]
For the last two years, the prevailing logic in generative AI has been one of brute force: if you want better reasoning, you need a bigger model. While "small" models (under 10 billion param [...]
The first crewed mission of NASA's Artemis moon program may take off in a matter of days, with a launch window that opens on April 1, and as preparations are underway for that, the space agency i [...]
For the first time on a major AI platform release, security shipped at launch — not bolted on 18 months later. At Nvidia GTC this week, five security vendors announced protection for Nvidia's a [...]
After a tumultuous 2025 that saw it lose around 4,000 employees, NASA finally has an operating budget for 2026, and one that largely preserves its scientific capabilities. On Thursday, the Senate pass [...]
