NASA’s successfully tests RS-25 Rocket Engines

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The largest rocket element NASA has ever built, the core stage of NASA’s Space Launch System (SLS) rocket, fired its four RS-25 engines for 8 minutes and 19 seconds Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

The successful test, known as a hot fire, is a critical milestone ahead of the agency’s Artemis I mission, which will send an uncrewed Orion spacecraft on a test flight around the Moon and back to Earth, paving the way for future Artemis missions with astronauts.

NASA Conducts SLS Rocket Core Stage Test for Artemis I Moon Mission

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA conducted a hot fire Saturday of the core stage for the agency’s Space Launch System (SLS) rocket that will launch the Artemis I mission to the Moon. The hot fire is the final test of the Green Run series.

The test plan called for the rocket’s four RS-25 engines to fire for a little more than eight minutes – the same amount of time it will take to send the rocket to space following launch. The team successfully completed the countdown and ignited the engines, but the engines shut down a little more than one minute into the hot fire.

NASA to proceed with Green Run Hot Fire of Space Launch System Rocket

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – NASA is targeting the final test in the Green Run series, the hot fire, for as early as January 17th, 2021. The hot fire is the culmination of the Green Run test series, an eight-part test campaign that gradually brings the core stage of the Space Launch System (SLS) — the deep-space rocket that will power the agency’s next-generation human Moon missions — to life for the first time.

NASA conducted the seventh test of the SLS core stage Green Run test series – the wet dress rehearsal – on December 20th at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and marked the first time cryogenic, or super cold, liquid propellant was fully loaded into, and drained from, the SLS core stage’s two immense tanks.

Fully loading the propellant and detecting no leaks is a major milestone for the Green Run test series. A total of 114 tanker trucks delivered propellant to six propellant barges next to the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The barges deliver more than 733,000 gallons of liquid hydrogen and liquid oxygen to the core stage for NASA’s Space Launch System (SLS) rocket as part of the seventh test in the Green Run test series.

NASA’s Artemis I Rocket completes Four Green Runs

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – The Space Launch System (SLS) rocket core stage for the Artemis I lunar mission has successfully completed its first four Green Run tests and is building on those tests for the next phase of checkout as engineers require more capability of the hardware before hot-firing the stage and its four powerful engines.

Green Run is a demanding series of eight tests and nearly 30 firsts: first loading of the propellant tanks, first flow through the propellant feed systems, first firing of all four engines, and first exposure of the stage to the vibrations and temperatures of launch.

The Space Launch System (SLS) rocket is completing the Green Run test for the rocket’s core stage, shown installed on the top left side of the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. For Green Run, the team is completing a series of eight tests culminating with Test 8, a full-up hot fire test that lasts eight minutes. Flames from the test will exit out of the yellow flame bucket shown here on the north side of the test stand. (NASA/Stennis)

NASA Completes Structural Testing of Artemis Space Launch System

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – On Wednesday, June 24th, 2020, engineers completed the Space Launch System (SLS) rocket’s structural testing campaign for the Artemis lunar missions by testing the liquid oxygen structural test article to find its point of failure.

“The Space Launch System and Marshall test team have done a tremendous job of accomplishing this test program, marking a major milestone not only for the SLS Program but also for the Artemis program,” said John Honeycutt, the SLS Program Manager. “From building the test stands, support equipment and test articles to conducting the tests and analyzing the data, it is remarkable work that will help send astronauts to the Moon.”

Engineers completed almost 200 tests on the Space Launch System (SLS) rocket by breaking the liquid oxygen tank test article. This test was the last in a 3-year structural campaign to ensure the rocket’s structure was designed to endure the rigors of spacefllight. (NASA/David Olive)
