NASA to conduct second rocket take a look at for Artemis moon missions

NASA will conduct its second Inexperienced Run scorching hearth take a look at of the core stage for its House Launch System (SLS) rocket

In a Monday launch, the company introduced that it was focusing on a two-hour take a look at window on Thursday, March 18 at 3 p.m. ET at NASA’s Stennis House Heart close to Bay St. Louis, Mississippi.


Engineers will energy up the core stage techniques, load greater than 700,000 gallons of cryogenic propellant into the tanks, and hearth the SLS rocket’s 4 RS-25 engines on the similar time to simulate the launch and generate 1.6 million kilos of thrust. 

The 212-foot tall core stage — put in within the renovated B-2 Check Stand — provides the SLS rocket the tallest rocket stage the company has ever constructed. It’s made up of engines, a liquid hydrogen tank, a liquid oxygen tank and electronics, avionics and computer systems.

The core stage design can be used for all configurations of the SLS rocket, so Inexperienced Run assessments — of which there are eight — are essential to the success of NASA’s subsequent lunar missions

The time period “inexperienced” refers back to the new {hardware} used to energy the stage and “run” refers to all parts functioning collectively concurrently for the primary time.


The new-fire take a look at is the eighth and last take a look at of the Inexperienced Run sequence that can make sure the core stage is able to launch NASA’s Artemis missions to the moon.

“The SLS core stage is an engineering feat that features not solely the most important rocket propellant tanks ever constructed but additionally refined avionics and principal propulsion techniques,” Lisa Bates, SLS deputy phases supervisor, stated in a July 2019 launch. “Whereas the rocket is designed to evolve over time for various mission aims, the core stage design will stay mainly the identical. The Inexperienced Run acceptance take a look at provides NASA the boldness wanted to know the brand new core stage will carry out many times as it’s supposed.”

The complicated core stage was constructed and manufactured at NASA’s Michoud Meeting Facility in New Orleans earlier that very same yr.

“Inexperienced Run is a historic second for NASA and Stennis for a lot of causes,” stated Stennis House Heart Director Richard Gilbrech in the identical launch. “For the primary time in NASA’s historical past, a launch automobile will use flight {hardware} for its first take a look at, and the Stennis take a look at stands will as soon as once more take a look at the core stage for Moon missions.”

The John C. Stennis House Heart is the nation’s largest rocket engine take a look at complicated.


As soon as validation of the stage is full, the stage can be refurbished as wanted and shipped to NASA’s Kennedy House Heart in Florida for the Artemis 1 launch.

NASA plans to start stay protection of Thursday’s hot-fire take a look at on NASA Tv, the NASA app, social media and the company’s web site and a briefing on the take a look at can also be scheduled for roughly two hours later.
