  "account": "On October 21, 2026, NASA conducted a hot fire test of RS-25 engine No. 10001 at Stennis Space Center in Mississippi. The engine, designated for future Artemis missions, was fired for 500 seconds, matching the duration required for the SLS rocket's launch. The test also pushed the engine to 111% power, equivalent to the thrust needed for launching the SLS rocket and Orion spacecraft. The primary goals of the test were to evaluate flight components for Artemis missions and validate a new thermal protection system for the engine nozzle. This test, conducted by teams from NASA, L3Harris Technologies, and Nova Space Solutions, provided valuable data to enhance engine performance and reliability. Although the used engine will not be used in actual flights, the insights gained will contribute to the development of future Artemis missions.",
  "summary": "NASA tested RS-25 engine No. 10001 on Oct. 21 on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Test teams fired the developmental engine for almost eight-and-a-half minutes (500 seconds), the same amount of time RS-25 engines fire during launch of NASA’s SLS (Space Launch System) rocket.
