NASA's SPHEREx telescope unveiled its first full-sky map of the universe, combining more than 100 infrared observations into one dazzling mosaic. Half a year after first opening its eyes to the cosmos, NASA 's SPHEREx spacecraft has unveiled its first complete, all-sky mosaic of the universe.

NASA has postponed a spacewalk at the International Space Station after a crew member experienced a medical concern.

Spacecraft are assembled in specialized “cleanrooms” that are designed to avoid contamination from dust and microorganisms. But bacteria called extremophiles have genetic components that allow them to survive in extreme environments, and 26 of them have been found at NASA’s Kennedy Space Center in Florida.

Scientists discover 26 new bacterial species in NASA cleanrooms, revealing surprisingly resilient microbes with potential uses in biotechnology and medicine.

NASA’s ESCAPADE mission is being held up as a test case for a new era of cheaper planetary science, one where small spacecraft and commercial rockets promise big discoveries at a fraction of traditional costs.
