Показать описание
An Aerojet Rocketdyne RS-25 rocket engine was tested on the A-1 Test Stand at the John C. Stennis Space Center in Mississippi, on 20 May 2021, at 19:15 UTC (14:15 CDT, 15:15 EDT). The test was conducted using the RS-25 developmental engine No. 0528 and had a planned duration of 500 seconds. This RS-25 hot-fire test is part of the Retrofit-2 test series, aiming to evaluate new engine components and reduce risk in engine operation. NASA’s Space Launch System (SLS) will be powered by four RS-25 engines firing simultaneously.

Will the engines be tested in a most brutal weather condition? Worst than the weather that Space Shuttle had to endure on the launch pad? You never know. It could happen.
