Briefings

NASA conducted a hot fire test of RS-25 engine No. 10001 on Oct. 21, 2026, at the Fred Haise Test Stand near Bay St. Louis, Mississippi. The test lasted 500 seconds, matching the duration of an SLS rocket launch, and reached 111% power to validate thrust for Artemis missions. This test supports future Moonwalk simulations and ensures engine reliability for the Artemis program.

Key points

• Engine No. 10001 was tested for 500 seconds (8.33 minutes) at 111% power on Oct. 21, 2026.
• The test validated the thermal protection system and flight components for future Artemis missions.

Context

This test occurred at NASA's Stennis Space Center near Bay St. Louis, Mississippi, as part of preparations for next Moonwalk simulations. The test supports future Artemis missions by validating engine performance and thermal protection systems for the SLS rocket and Orion spacecraft.

Limitations

Evidence is limited to a single hot fire test of one engine; no data on total engine count, specific launch outcomes, or long-term reliability metrics are provided.
