NASA’s Space Launch System (SLS) rocket with the Orion spacecraft aboard is seen at sunrise atop a mobile launcher at Launch Complex 39B, Monday, April 4, 2022, as the Artemis I launch team conducts the wet dress rehearsal test at NASA’s Kennedy Space Center in Florida. Ahead of NASA’s Artemis I flight test, the wet dress rehearsal will run the Artemis I launch team through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch.

Standing 17 stories tall, the SLS twin solid rocket boosters produce 7.2 million pounds of thrust at launch. When their job is done, 16 booster separation motors then ignite to safely push the boosters away from the rocket. LEARN MORE >> go.nasa.gov/4jPA71Y

In 2007, Liliana Villarreal joined @NASA. Now, she's the Artemis Landing and Recovery Director. “I think it’s an amazing thing what we’re doing for humanity. It’s going to better humanity, and it’s a steppingstone to eventually us living in other worlds. And I get to be part of that. You get to be part of that. How cool is that?” - Lili Learn about her journey here: go.nasa.gov/3Ze0ebj

Pumped up! ⛽ Teams with Exploration Ground Systems ready @NASA_Orion for stacking atop the Artemis II @NASA_SLS rocket by fueling the service module, provided by @esa. To complete this operation, teams stationed in the Launch Control Center oversee and direct fueling operations, while teams in the Multi-Payload Processing Facility respond to manipulate valves and load the flight hardware’s bipropellant system. The service module is the powerhouse of the Orion spacecraft. It will provide in-space maneuvering capability, power, and life support commodities such as water, oxygen, and nitrogen for @NASAArtemis missions.
Technicians with NASA’s Exploration Ground Systems offload the agency’s Orion spacecraft from the KAMAG transporter to the servicing stand inside the Multi-Payload Processing Facility at Kennedy Space Center in Florida on Sunday, May 4, 2025, to undergo fueling and processing operations for prelaunch operations.

NASA has signed its fourth and final agreement for the international CubeSats that will fly aboard the SLS during Artemis II. The CubeSats, which will deploy from the Orion stage adapter, contain technology demonstrations or scientific experiments that can potentially enhance understanding of the space environment. 🔗 go.nasa.gov/43HLuUB
These photos show highlights from Artemis II NASA astronauts Victor Glover, Reid Wiseman, and Christina Koch of NASA and CSA (Canadian Space Agency) astronaut Jeremy Hansen visit to NASA’s Marshall Space Flight Center in Huntsville, Alabama, Nov. 27. The crew met and spoke to employees and viewed facilities for SLS (Space Launch System) rocket. All four astronauts signed the Orion stage adapter (OSA), a small ring structure that connects SLS to NASA’s Orion spacecraft, that will be used for Artemis II. Koch and Wiseman also visited the Systems Integration Lab, where SLS flight software testing is conducted. The four astronauts will launch atop SLS inside Orion to venture around the Moon on Artemis II, the first crewed flight for Artemis. Image Credit: NASA/Charles Beason
