NASA Unboxes RS-25 Engines for the First Crewed Artemis Mission
Teams at NASA’s Michoud Assembly Facility in New Orleans have unboxed all four RS-25 engines that will be used to help power NASA’s Space Launch System (SLS) rocket for Artemis II, the first crewed Artemis mission that will send four astronauts on a lunar flyby around the Moon.

NASA’s Webb Spots Swirling, Gritty Clouds on Remote Planet
Researchers observing with NASA’s James Webb Space Telescope have pinpointed silicate cloud features in a distant planet’s atmosphere. The atmosphere is constantly rising, mixing, and moving during its 22-hour day, bringing hotter material up and pushing colder material down. The resulting brightness changes are so dramatic that it is the most variable planetary-mass object known to date.

NASA Conducts Long Duration Hot Fire of RS-25 Certification Engine
NASA conducted a long duration hot fire of an RS-25 certification engine March 21, continuing a key series of testing to support future Space Launch System (SLS) missions to deep space as part of Artemis missions. Operators fired the certification engine for 10 minutes (600 seconds), longer than the 500 seconds engines must fire during an actual mission.

NASA Connects All Major Structures of Artemis II Moon Rocket Core Stage
Teams at NASA’s Michoud Assembly Facility in New Orleans have fully integrated all five major structures of the Space Launch System (SLS) rocket’s core stage for Artemis II, the first crewed Artemis mission that will send four astronauts around the Moon and return them home. Technicians joined the engine section to the rest of the rocket stage March 17.
