NASA carried out the primary take a look at of the newly redesigned RS-25 engine for future flights of the House Launch System (SLS) rocket Dec. 14, finishing 209.5 seconds of a scheduled 500 second sizzling hearth on the company’s Stennis House Middle close to Bay St. Louis, Mississippi.
The recent hearth take a look at was shut down early by a non-flight system used to observe the engine. NASA and House Launch System lead engine contractor Aerojet Rocketdyne are analyzing knowledge to overview the monitoring system, consider engine efficiency, and determine the explanation for the early take a look at cutoff. As a result of the take a look at was being achieved for redesigned engines in help of Artemis V and past, no impacts to RS-25 {hardware} for earlier missions is anticipated.
“Very similar to launch, take a look at campaigns are dynamic occasions that permit us to study extra in regards to the SLS rocket {hardware},” stated Johnny Heflin, liquid engines supervisor for the House Launch System at NASA’s Marshall House Flight Middle in Huntsville, Alabama. “NASA and Aerojet Rocketdyne groups have been profitable in working the primary take a look at of the brand new RS-25 restart engine for 209.5 seconds that can assist energy future missions with the SLS rocket. Preliminary knowledge signifies the engine was performing nominally. Information evaluation is underway.”
The only-engine sizzling hearth, often known as a confidence take a look at, was designed to verify all is able to proceed with a sequence of certification exams early subsequent yr on a full RS-25 certification engine. NASA and the corporate modified 16 of the engines remaining after the House Shuttle Program to be used on Artemis mission I by IV. The upcoming sequence of testing is for the RS-25 engines that can be used starting with Artemis V.
“Every take a look at, even one that doesn’t go full length, helps us collect beneficial knowledge and helps us put together to fly safely,” stated Chip Ellis, Stennis RS-25 venture supervisor.
The take a look at on the Fred Haise Take a look at Stand at Stennis got here simply days after NASA efficiently accomplished the Artemis I flight take a look at in preparation for future missions to the Moon.
The take a look at offered preliminary knowledge to help NASA and Aerojet Rocketdyne as the corporate prepares to start manufacturing of recent RS-25 engines to energy future Artemis missions to the Moon and past. For every SLS flight, 4 RS-25 engines, together with a pair of stable rocket boosters and core stage, assist energy the rocket at liftoff.
The recent hearth was testing new RS-25 parts for use in manufacturing of future engines, together with a brand new powerhead part. Further parts, together with a brand new nozzle and controller, can be put in on the engine previous to the beginning of the certification sequence.
The recent hearth marked the primary take a look at on the Fred Haise Take a look at Stand since March when NASA accomplished developmental testing for Aerojet Rocketdyne efforts to modernize manufacturing processes and cut back manufacturing prices of future engines. Since that point, Stennis groups have accomplished essential take a look at stand upkeep initiatives to help the RS-25 testing program. These included work to improve the stand’s high-pressure industrial water system, flame deflector, thrust vector management system, and knowledge acquisition system.
4 RS-25 engines assist energy every SLS flight, firing concurrently to generate a mixed 1.6 million kilos of thrust at launch and a pair of million kilos of thrust throughout ascent. Each RS-25 engine that can assist energy SLS can be examined at Stennis. RS-25 exams on the website are carried out by a mixed crew of NASA, Aerojet Rocketdyne and Syncom House Companies operators. Syncom House Companies is the prime contractor for Stennis services and operations.
By means of Artemis missions, NASA will land the primary girl and the primary particular person of colour on the floor of the Moon, paving the way in which for a long-term lunar presence and serving as a steppingstone on the way in which to Mars.

NASA starts RS-25 engine testing for future Artemis missions
Washington DC (UPI) Dec 13, 2021
NASA will begin sizzling hearth testing for the manufacturing of recent RS-25 engines that can energy future Artemis missions to the Moon, and finally Mars.
The preliminary single-engine sizzling hearth take a look at Wednesday, at Stennis House Middle close to Bay St. Louis in Mississippi, will run for 500 seconds beginning at 2 p.m. CST.
“It’s thrilling to return to sizzling hearth testing on the historic Fred Haise Take a look at Stand and get again to the enterprise of testing for future Artemis missions,” stated NASA Stennis RS-25 venture … read more
