The mission served as a crucial flight test of the Orion spacecraft and Space Launch System (SLS) rocket with a crew aboard, paving the way for future lunar landings.\n\n**Mission Objectives & Crew:**\n\nArtemis II’s primary objective was to send a crew on a lunar flyby mission, demonstrating the capabilities of the SLS rocket and Orion spacecraft to safely transport humans beyond low Earth orbit. The four-person crew consisted of Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen (Canadian Space Agency).\n\n**Key Milestones:**\n\n*   **Launch:** The mission launched on April 1, 2026, from Kennedy Space Center’s Launch Complex 39A in Florida.

The SLS Block 1 configuration provides approximately 8.8 million pounds of thrust at liftoff.
