The SLS configuration used for Artemis II is designed to support crewed flight following the uncrewed Artemis I test.
Artemis I launched uncrewed from Space Launch Complex 39B on November 16, 2022.
Data from Artemis I provided the baseline required to certify the SLS and Orion for human occupancy.
Artemis I sent the Orion spacecraft into a distant retrograde lunar orbit and tested the capsule’s heat shield during a high-velocity re-entry that reached 5,000 degrees Fahrenheit.
NASA has incorporated lessons learned from Artemis I into the countdown procedures for the launch.
Artemis I was an uncrewed test flight launched in November 2022 to validate NASA's space exploration systems.

The solution for Artemis II's heat shield involves a gentler reentry to prevent gas buildup that caused damage in Artemis I.
Orion Deputy Program Manager Debbie Korth indicated that a theoretical crew aboard Artemis I would have been fine despite the heat shield damage.
The previous Orion spacecraft, which journeyed to the Moon during uncrewed Artemis I in 2022, experienced charring and bolt melting on the heat shield.
NASA added strakes near booster attachment points to counter vibration levels observed on Artemis I.
Engineers adjusted booster separation mechanics by angling the separation motors 15 degrees and initiating jettison four seconds earlier than in Artemis I.
