NASA Conducts Most Powerful Rocket Engine RS-25 for Space Launch System

4 min read

The aerospace engineers of NASA moved a step ahead on writing names on a gold plate when they successfully conducted most powerful rocket engine RS-25 test for Space Launch System (SLS) on July 29, 2016. The engine no. 0528 got designed to collect critical performance data on behalf of the respective Rocket.


The engine ignited with a huge roar for 650 seconds continuously on the A-1 Test Stand in Stennis Space Centre, near Bay St. Louis, Mississippi. The following test experiment held the second time in SLS will help launch humans in further spaces traveling deeper than ever before, including the journey to the Mars. The development was made in regards of space exploration petition.

NASA earlier made 4 attempts on a series of development experiments before a test flight which might be used in near future named as Exploration Mission-2. The respective future prospective Rocket would be first crew flight in Orion Spacecraft launching on SLS.

The engine experimentation held on July 29th, comprised of 4 RS-25 engines, adjoined with solid rocket boosters powering the core stage during launch. The engines are previous SLS space shuttle main engines simply modified to perform in more than above moderate level consisting new engine controller thus creating communicating bridge between the engine and the vehicle.

The following test was conducted in the presence of a team of NASA, Aerojet Rocketdyne and Syncom Space Services Engineers and Operators. The test held on 29th along with future tests scheduled on four different dates are focused towards new engine controllers and high operating parameters. The new developments seen after the tests states that the engines RS-25 will meet the new set parameters which are equally modernized for future space flight experience.

In near future, during the firings/ignitions, the engines will go through series of adaptations such as changes in temperatures, pressures, etc.  Also, the team will keep a close watch over the new engine controller function so as to ensure safety. As of now, all flight testing for SLS takes place at Stennis, along with the actual core stage testing for the first integrated mission of SLS and NASA’s Orion spacecraft, Exploration Mission-1. The next scheduled RS-25 developmental test at Stennis will be held on August 18, 2016. Apart from existing RS-25 rocket engines, NASA has teamed up with Aerojet Rocketdyne to build additional engines for future tests on SLS.
