NASA fires RS-25 engine No. 10001 for eight‑minute test at Stennis
The eight‑minute hot‑fire test validated flight components and a new thermal protection system for Artemis missions.
By Felo News Desk · Published
NASA conducted an eight‑minute hot‑fire test of RS‑25 engine No. 10001 on Oct. 21 at the Fred Haise Test Stand, Stennis Space Center, Mississippi, according to a NASA release.
What happened
The developmental engine fired for about 500 seconds, matching the burn duration of RS‑25 engines on the Space Launch System (SLS). Operators pushed the engine to 111% of its rated power, the level required for future production engines.
What the report adds
The test aimed to acceptance‑test flight components for upcoming Artemis missions and to validate a new thermal protection system for the engine nozzle. Although the engine will not fly, the data will help improve performance and reliability for the SLS and Orion spacecraft.
What was said
Bo Black, communications strategist, noted that the test provides NASA and its prime contractor L3Harris Technologies with critical data.
How it came about
The test follows a series of recent Artemis‑related activities, including NASA’s media briefing on the program’s acceleration and the release of Artemis II data earlier this month.
