NASA led to its new phase Space launch system On Saturday (December 5), agency officials said they had begun testing the “green run” of the next-generation megrocket.
For this “wet dress” rehearsal exercise, NASA engineers Stennis Space Center For the first time in Mississippi, the main stage of a rocket launcher (SLS) is planned to be loaded with propellant, a process that will begin on Monday (December 7) and last about 48 hours, NASA officials wrote in a blog post. That fueling process began on schedule, but was suspended by NASA engineers after it began to allow time for further analysis.
Prior to this wet dressing exercise, NASA installed a 212-foot (65 m) core stage through six green run tests. These experiments will test whether the SLS Core Stage, built by Boeing, is ready to bring a crew safely into space as part of it. Artemis Program. This behemoth spacecraft is designed to bring humans back to the lunar surface by 2024, with the potential for manned travel into deep space.

The core stage was subjected to its major experiments at the B-2 test stand at NASA’s Stennis Space Center near Bay St. Louis. Established there on January 22nd. In this chapter of the eight-part test series, engineers load 700,000 gallons (2.6 million liters) of supercooled propellant, a combination of cryogenic or liquid hydrogen and oxygen. This is the first time the SLS core stage has been filled with propellants, so engineers were closely monitoring for signs of leaks or other problems when filling the tank.
“In order to test the propellant loading procedures, the engineers successfully loaded a small amount of liquid hydrogen into the core stage without any problems. ) In a blog post.
“Operations are ongoing, team procedures will be revised and the wet dress rehearsal test will resume in the coming days. The core stage performed well and there are no problems with the stage, B-2 test stand or other facilities.”
An update on the Green Run test: #NASASLS has strengthened the core stage as part of the seventh test of the series. Before resuming the wet dress rehearsal test, the engineers review the data and update the procedures. @ More on NASA’s #Artemis Blog: https://t.co/PTaxAadPXO pic.twitter.com/a2D8no6IWXDecember 8, 2020
The core stage is designed More than 2 million, NASA will use this special core stage to launch NASA’s Artemis 1, the first test flight of the Artemis program, which will send a detached Orion capsule on a journey around the Moon. Artemis 1 is currently launching at the end of 2021.
“In preparation for the Artemis launches, engineers will set the stage through the conditions the pad may experience before taking off ഇത് It provides an opportunity to observe how the stage will react during an upcoming hot fire test or if the countdown is suspended. Future Artemis launch, ”NASA officials said In a previous blog post.
As with the prototype of the scrubbed launch, all propellants will be removed from the core’s tanks after this test, NASA officials wrote.
If the data confirms that everything went well during this wet clothing rehearsal, the team will move forward with plans for the final event of the series, the Hot Fire Test.
