NASA successful hot fire tests Space Launch System rocket that will support NASAs Artemis astronauts reach the moon

The Space Launch System rocket that will launch NASA’s Artemis astronauts into space on their way to the moon went through a final and successful hot-fire test of the core stage on Thursday.

The test occurred at NASA’s Stennis Space Center external Bay St. Louis, Mississippi, and started at 4:40 p.m. ET. The test lasted for just more than eight minutes.

“The SLS is the most powerful rocket NASA has ever built, and during today’s test, the core stage of the rocket generated more than 1.6 million pounds of thrust within seven seconds. The SLS is an incredible feat of engineering and the only rocket capable of powering America’s next-generation missions that will place the first woman and the next man on the Moon,” said acting NASA Administrator Steve Jurczyk in a statement.

“Today’s successful hot fire test of the core stage for the SLS is an important milestone in NASA’s goal to return humans to the lunar surface — and beyond.”

This was the eighth and final in the Green Run series of tests intended to guarantee that the rocket can launch Artemis missions that will land the first woman and the next man on the moon in 2024. The first mission, the uncrewed Artemis I, is planned for November. These tests can help answer questions regarding how the rocket may perform all through various stages of launch.

The rocket’s core stage systems were stacked with more than 700,000 gallons of supercold propellant and the four RS-25 rockets were fired simultaneously. This reproduces what the rocket will suffer during launch, even though SLS will use about 8.8 million pounds of push to take Artemis I off the pad.

The core stage incorporates the four engines, liquid hydrogen tank, liquid oxygen tank, and the avionics – PCs and electronics that work in concert as the rocket’s “brains” that control the initial eight minutes of flight – as indicated by the agency.

Between 18 to 20 big tanker trucks full of propellant filled six barges with the liquid oxygen and hydrogen in the days before the test. The barges were then towed to the B-2 rocket remain to fill up the core stages.

This second, longer hot-fire test was considered significant after the first in January finished sooner than planned. The first hot-fire test was required to last for eight minutes, however, cut off soon after one minute.

The second test went on for eight minutes, giving the groups the information they need. Applause could be heard from the control room after they provided the command to close it down following eight minutes. Nothing provoked an early closure.

During the test, the engines experienced three different power levels as well as movements that simulate flight steering, called gimballing.

In the weeks before the test, groups ensured that a liquid oxygen pre-valve that must be repaired was working. They likewise investigated information from the first test, remembering the parameters on the flight computer that finished the first test sooner than planned. Furthermore, they made minor repairs.

“This longer hot fire test provided the wealth of data we needed to ensure the SLS core stage can power every SLS rocket successfully,” said John Honeycutt, manager for the SLS Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama, in a statement.

“During this test, the team conducted new operations with the core stage for the first time, repeated some critical operations, and recorded test data that will help us verify the core stage is ready for the first and future SLS flights for NASA’s Artemis program.”

The Artemis program will start with missions to the moon with a plan to depend on the SLS rocket as an approach to send astronauts on to Mars too.

Teams will keep on evaluating the information assembled from the test. After about a month of renovating the core stage and engines, the Pegasus barge will carry the core stage on to its next home.

The SLS rocket will be shipped to NASA’s Kennedy Space Center in Florida so it tends to be collected and integrated, alongside the Orion shuttle intended for the astronauts.

At Kennedy, teams have effectively stacked the strong rocket boosters in the Vehicle Assembly Building for Artemis I.

Jurczyk said Thursday that the Biden administration has been supportive of NASA and its targets and objectives for the Artemis program and the agency’s Moon to Mars strategy.

Getting back to the moon

The first 18 astronauts of the Artemis program were selected and reported in December.

The different team of astronauts incorporates Joseph Acaba, Kayla Barron, Raja Chari, Matthew Dominick, Victor Glover, Warren “Woody” Hoburg, Jonny Kim, Christina Koch, Kjell Lindgren, Nicole Mann, Anne McClain, Jessica Meir, Jasmin Moghbeli, Kate Rubins, Frank Rubio, Scott Tingle, Jessica Watkins, and Stephanie Wilson.

At the point when astronauts investigate the lunar south pole, which has never been visited by humans before, they will expand on the legacy and science acquired during the Apollo program and carry it into a new century.

After the uncrewed Artemis I flight in November, Artemis II will be a crewed flyby of the moon in August 2023. Artemis III will return astronauts to the moon.

The SLS rocket will send Orion, astronauts, and enormous cargo to the moon all at once, NASA said.

The Orion rocket can carry four crew members and support deep-space missions, dissimilar to past craft designed for short flights.

Orion will dock at the Gateway, a planned lunar outpost that will orbit the moon. Around 250,000 miles from Earth, the Gateway will permit simpler access to the whole surface of the moon and, conceivably, deep-space investigation.

The Artemis III Science Definition Team has distinguished a few priorities for this groundbreaking team of Artemis astronauts. These include conducting experimental science for the moon, researching and moderating the dangers of investigation, and understanding the origin of the elements at the lunar poles – like water and different resources that could be used by astronauts.

The agency additionally wants to build up an Artemis Base Camp before the decade’s over at the lunar south pole.
