Space Coast, FL – On March 18, 2021, NASA conducted it’s second Space Launch System (SLS) hot fire. This was the final test in the Green Run Test. It was the igniting of four Aerojet Rocketdyne RS-25 engines. All of which have previously flown on a Space Shuttle during the Space Shuttle program.
SLS (Space Launch System) Data Analysis
The core stage has an intricate network of flight software and avionics systems. They are designed to help fly, steer and track the rocket during lift off and flight. Previous tests in the Green Run test series evaluated the integrated functionality and performance of the core stage’s avionics systems, propulsion systems, and hydraulic systems.
The over eight minute hot fire tested a variety of workable conditions. Including moving the four engines in particular patterns to direct thrust and increasing the engines up to 109% power, throttling down and back up, just as they would during a flight.
Going forward, the core stage for SLS will be refurbished, then shipped to NASA’s Kennedy Space Center in Florida. Expected in late April.
