Briefings
NASA and L3Harris conducted a hot fire test of RS-25 engine No. 10001 at Stennis Space Center on October 21, 2026. The test lasted 500 seconds at 111% power, matching the duration of SLS rocket launches. This engine is a developmental unit not yet used in flight, but the test enables critical data collection to enhance performance and reliability for future Artemis missions.
Key points
- Engine No. 10001 was tested at Stennis Space Center on October 21, 2026, lasting 500 seconds at 111% power.
- The test provides data to improve engine performance and reliability for future Artemis missions.
Context
This test occurred at NASA Stennis Space Center near Bay St. Louis, Mississippi. It is part of a series of hot fire tests for the RS-25 engine, which is a key component for NASA's SLS rocket and Artemis missions.
Limitations
The evidence is limited to a single hot fire test of one engine. No flight data or operational history is provided. The engine is developmental and not yet used in flight.
