CubeSats on Artemis 1 to pursue bold missions in deep space, if they overcome battery concerns
The 10 CubeSats hitching a ride to deep space on NASA's Space Launch System moon rocket promise new discoveries about the moon, space weather, and asteroids. But some of the small spacecraft will launch with their batteries only partially charged after sitting inside the rocket for more than a year.
Europe plays key role in NASA’s epic return to the moon
European space officials have hailed the importance of NASA’s upcoming inaugural Artemis mission and the vital role ESA is playing in supporting a return to the moon.
NASA managers give “go” for Artemis 1 launch after flight readiness review
With one week to go until launch, NASA managers met at the Kennedy Space Center, reviewed flight preparations and cleared the agency's huge $4.1 billion Space Launch System rocket for blastoff next Monday on a test flight heralding an American-led return to the moon.
