AI에 의해 보고됨 AI에 의해 생성된 이미지
Orion spacecraft from Artemis 2 mission has completed its final maneuver before atmospheric reentry, the most critical phase of the journey. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen face a 13-minute descent at over 40,000 km/h and temperatures above 2,500 degrees, with splashdown planned off San Diego.
Researchers have developed minuscule devices that use light to control movement in multiple directions, advancing the potential for light-powered spacecraft. The metajets, made from silicon, were tested in a lab setting and showed promising results for steering large sails through space. This breakthrough could help overcome current limitations in directing such vessels over vast distances.

South African National Space Agency engineers at Hartebeesthoek Ground Station tracked NASA's Orion spacecraft during its record-breaking lunar flyby, ensuring communication during key phases. The Artemis II crew achieved a maximum distance from Earth of 406,771km, surpassing previous human spaceflight records. Sansa provided telemetry and ranging data as part of global collaboration.
