NASA conducted a full-duration RS-25 hot fire April 3 on the Fred Haise Test Stand at NASA\u2019s Stennis Space Center near Bay St. Louis, Mississippi, achieving a major milestone for future Artemis flights of NASA\u2019s SLS (Space Launch System) rocket. It marked the final test of a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power NASA\u2019s SLS rocket on Artemis missions to the Moon and beyond, beginning with Artemis V. <\/div>\n

The second \u2013 and final \u2013 RS-25 certification test series begins Oct. 17, 2023. When the liquid hydrogen and liquid oxygen propellants mix and ignite, an extremely high temperature exhaust, of up to 6,000-degrees Fahrenheit, mixes with water to form steam that exits the flame deflector and rises into the atmosphere, forming a cloud that subsequently cools.<\/div>\n

An RS-25 hot fire at NASA\u2019s Stennis Space Center on Nov. 15, 2023, marks the second test of a 12-test engine certification series. The NASA Stennis test team typically fires the certification engine for 500 seconds, the same amount of time engines must fire to help launch the SLS (Space Launch System) rocket to space with astronauts aboard the Orion spacecraft. <\/div>\n

Operators fire the RS-25 engine at NASA\u2019s Stennis Space Center on Nov. 15, 2023, up to the 113% power level. The first four Artemis missions are using modified space shuttle main engines that can power up to 109% of their rated level. New RS-25 engines will power up to the 111% level to provide additional thrust, so testing up to the 113% power level provides a margin of operational safety.<\/div>\n

For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS (Space Launch System) rocket, producing more than 8.8 million pounds of thrust at liftoff. <\/div>\n
