A new NASA satellite will test critical technologies for storing and transferring super-chilled, cryogenic fuels in space in order to help astronauts reach the moon and potentially Mars someday. The Liquid Oxygen Flight demonstration (LOXSAT) will launch to orbit around the Earth later this year to test the fluid management capabilities that will be needed to maintain cryogenic fuels in microgravity,

Researchers expected to find "a gradual increase in artificial light at night," but instead saw "much more nuanced patterns," NASA said.

A massive airplane-sized asteroid named (2026 JP1) is set to fly past Earth on May 20, 2026. Scientists say it is safe, but is this close approach a problem? Know here.

Maps can show more than just where things are—they can also show how things change. New maps of artificial light reveal a planet that has been reshaping its nights through patterns of brightening and dimming.

So why is NASA launching fewer telescopes and planetary science missions than it did a quarter-century ago? The answer is complex. It is not necessarily the money. The space agency’s science budget this year is $7.

SAN DIEGO (FOX 5/KUSI) — The astronauts aboard NASA’s Orion spacecraft on the Artemis II mission captured breathtaking photos of Earth during their 10-day journey to and from the moon. Three NASA astronauts, Reid Wiseman, Victor Glover, and Christina ...

NASA launched four astronauts on a pioneering journey around the moon—the Artemis II mission. Follow our coverage here. Just 14 days ago, amid the mundanity of East Coast commutes and West Coast alarm clocks, NASA’s Artemis II mission gave humans ...
