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.

Ingenieure der South African National Space Agency an der Hartebeesthoek Ground Station verfolgten das Orion-Raumschiff der NASA während seines rekordverdächtigen Mondvorbeiflugs und stellten die Kommunikation in Schlüsselphasen sicher. Die Artemis-II-Crew erreichte eine maximale Entfernung von 406.771 km zur Erde und übertraf damit frühere Rekorde der bemannten Raumfahrt. Sansa lieferte im Rahmen der globalen Zusammenarbeit Telemetrie- und Entfernungsdaten.
