Nasa

New research shows that Nasa's Dart spacecraft, which crashed into the asteroid moonlet Dimorphos in 2022, has changed the orbit of the binary asteroid system around the sun. This marks the first time a human-made object has measurably altered a celestial body's path in this way. The findings highlight potential methods for planetary defense against hazardous space objects.

Fifty-eight years after Apollo 8's lunar orbit, Nasa is set to launch Artemis II, a crewed flyby that will take astronauts farther from Earth than ever before. The mission will test key technologies for future lunar landings and mark a step toward a permanent moon base. The crew, currently in quarantine, includes commander Reid Wiseman, pilot Victor Glover, and mission specialists Christina Koch and Jeremy Hansen.
