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 to make Green Run test of it’s Space Launch System

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – On Thursday, July 25th, 2018, NASA Administrator Jim Bridenstine announced that the agency will conduct an “Green Run” core stage test for the Space Launch System rocket ahead of the upcoming Artemis 1 lunar mission.

The first eight minutes of every Artemis mission with NASA’s Space Launch System (SLS) rocket will begin with core stage and solid rocket boosters producing 8.8 million pounds of thrust to launch the agency’s Orion spacecraft to the Moon.

The “Green Run” test of the core stage for NASA’s Space Launch System (SLS) will be conducted at the B-2 Test Stand at NASA’s Stennis Space Flight Center near Bay St. Louis, Mississippi. The historic test stand has been used to test stages for multiple programs, including the Saturn V and the space shuttle. The test stand was renovated to accommodate the SLS rocket’s core stage, which is the largest stage NASA has ever built. (NASA)

NASA completes Second RS-25 Engine Hot Fire Test of 2018

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA followed up the first RS-25 test of 2018 with a second hot fire of the Space Launch System (SLS) engine on February 1st at Stennis Space Center near Bay St. Louis, Mississippi. The full-duration, 365-second certification test of another RS-25 engine flight controller on the A-1 Test Stand at Stennis comes about two weeks after a January 16th hot fire.

The test marks completion of green run testing for all four of the new RS-25 engine flight controllers needed for the second flight of NASA’s SLS rocket. NASA is building SLS to send humans to such deep-space destinations as the moon and Mars.

A Look Back at NASA’s efforts to send Astronauts into Deep Space from 2017

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Below are the top images from 2017 that tell the story of building and testing the systems that will send astronauts to deep space destinations including the Moon, Mars and beyond.

Construction Completed for Stand to Test SLS’s Largest Fuel Tank

Major construction is complete on NASA’s structural test stand that will ensure SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent. Together, the SLS liquid hydrogen and liquid oxygen tanks will feed 733,000 gallons (nearly 3 million liters) of super-cooled propellant to four RS-25 engines, producing a total of 2 million pounds of thrust at the base of the core stage.

The 215-foot-tall structural test stand for NASA's Space Launch System is seen Sunday, Sept. 24, 2017, at NASA's Marshall Space Flight Center in Huntsville, Alabama. (NASA/Bill Ingalls)

NASA Engineers successfully use 3-D Printed Part on RS-25 Rocket Engine

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Engineers successfully hot-fire tested an RS-25 rocket engine with a large 3-D printed part for the first time on December 13th, marking a key step toward reducing costs for future engines that power NASA’s new heavy-lift rocket, the Space Launch System.

During flight, a rocket may experience powerful up-and-down vibrations mainly due to the engines and propellant in the feed lines. This is called the pogo effect and is similar to the up-and-down motion of bouncing on a pogo stick. The 3-D printed part tested, called the pogo accumulator, is a beachball-sized piece of hardware that acts as a shock absorber by regulating liquid oxygen movement in the engine to prevent the vibrations that can destabilize a rocket’s flight.

The successful hot-fire test of an RS-25 development engine at NASA's Stennis Space Center on Dec. 13 included NASA's largest 3-D printed rocket engine component to date, the pogo accumulator assembly. The test was the first of 50 for NASA's restart of RS-25 engine production. (NASA/Stennis)

NASA tests Rocket Engine for Crewed Space Missions

 

Written by Valerie Buckingham
NASA’s Stennis Space Center

NASA - National Aeronautics and Space AdministrationJohn C. Stennis Space Center, MS – Most people never view a rocket launch in person, but more than 1,500 people watched the next closest thing at a NASA facility October 19th, 2017 – a verification test of a rocket engine that will power a crewed mission to space.

As visitors at NASA’s Stennis Space Center in Mississippi learned during the recent Stennis Founders Day Open House event, there were a number of unique factors about this particular test.

NASA engineers conduct a full-duration, 500-second test of RS-25 flight engine E2063 on the A-1 Test Stand at Stennis Space Center on Oct. 19, 2017. Once certified, the engine is scheduled to help power NASA’s new Space Launch System rocket on its Exploration Mission-2. The test was part of Founders Day Open House activities at Stennis.
