NASA's Orion spacecraft successfully executed a 5-minute and 50-second main engine burn, placing four astronauts on a trajectory around the Moon. This historic mission, part of the Artemis II program, marks the first time humans have ventured beyond low-Earth orbit since the last Apollo mission in 1972. The spacecraft launched from Kennedy Space Center aboard NASA's Space Launch System rocket and is set to fly around the Moon, utilizing lunar gravity to return to Earth, with a splashdown scheduled for April 10. The crew, comprising Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen, conducted critical checks on the spacecraft's life support and propulsion systems to ensure they are prepared for deep-space conditions. NASA officials expressed satisfaction with the mission's progress, noting that all systems, including the carbon dioxide scrubbers, are functioning well despite a minor issue with the toilet system that was quickly resolved.
