NASA Achieves Testing Milestone with Engines for Initial SLS MissionsNASA conducted a hot fire test of RS-25 flight engine No. 2062 on the A-1 Test Stand at Stennis Space Center on April 4, with a full-duration of 500 seconds. The hot fire caps more than four years of testing for engines that will help power the first four missions of NASA’s new Space Launch System (SLS) rocket. All 16 former space shuttle main engines that will help launch the first four SLS missions have undergone acceptance testing and have completed developmental and acceptance testing for new controllers to be used by the engines. It also concludes a 51-month test series that demonstrated RS-25 engines can perform at the higher power level needed to launch the super heavy-lift SLS rocket.
NASA conducted a hot fire RS-25 test on engine 0528 on Jan 28 for a full duration of 500 seconds.https://www.nasa.gov/centers/stennis/news/releases/2021/NASA-Conducts-1st-Hot-Fire-of-New-RS-25-Engine-Test-Series
NASA conducted a second RS-25 single-engine hot fire test on April 6 to support the development and production of engines to help power the agency’s Space Launch System (SLS) rocket on future missions to the Moon. The full-duration hot fire of more than eight minutes (500 seconds) was conducted on the A-1 Test Stand at Stennis. It is part of a scheduled seven-test series designed to provide valuable data for Aerojet Rocketdyne, as it begins production of new RS-25 engines for use after the first four SLS flights.
BTW, now that the green run test is complete on the B-2 stand, does this mean the B-2 will bo mothballed? Isn't B-2 reserved for full stage/multi-engine testing, of which there are none in the foreseeable future? Thx
Current/Scheduled Work:Scheduled for SLS Core Stage in 2020Scheduled for Exploration Upper Stage testing in future
NASA has completed the last of 7 RS-25 engine tests. Engines that will be used after the Artemis 4 mission! 🔥
