NASA has successfully tested an SLS rocket that will help Artemis astronauts reach the moon

The test took place at NASA’s Stanislaus Space Center outside of St. Louis, Mississippi, and began at 4:40 p.m. The test lasted only eight minutes.

“SLS has built the most powerful rocket ever, and NASA hit more than 1.6 million pounds of thrust in the main phase of the rocket in seven seconds during today’s test. And will put the next man on the moon, NASA executive Steve Zurzic said in a statement.

“Today’s successful hot-fire test of the main phase for SLS is an important milestone in NASA’s goal of bringing humans back to the lunar surface.”

The green run was the eighth and final in a series of tests designed to ensure that the first woman and the next man land on the moon in 2024. For November. These tests can help answer questions about how a rocket can operate during different phases of a launch.

The rocket’s core stage systems were filled with more than 700,000 gallons of supercold propellant and four RS-25 rockets were launched at the same time. This mimics what the rocket will endure during the launch, although the SLS Approximately is.8 million pounds of thrust will be used to lift Artemis I from the pad.

The main phase consists of four engines, a liquid hydrogen tank, a liquid oxygen tank and avionics – computers and electronics that act as the “brain” of the rocket in the galaxy that controls the first eight minutes of flight – According to the agency.

Eight to 20 tanker trucks loaded with propellant filled six barges with liquid oxygen and hydrogen in the first days of testing. These belts were then tied to the B-2 rocket stand to fill the main stages.

This second, longer hot ordeal was deemed necessary after the completion of the first examination scheduled in January. The first hot-fire test was expected to last eight minutes, but it was cut off a minute later.

The second test lasted eight minutes, providing the teams with the necessary data. Applause was heard from the controlroom after they ordered it shut down eight minutes later. Nothing prompted an initial shutdown.

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

During the test four engines experienced a movement called gimboling.

In the week before the test, the teams made sure the liquid oxygen pre-valve that had to be repaired was working. They also analyzed the data of the first test, including the parameters of the flight computer, who completed the first test before planning. And they made minor repairs.

“We have been provided with the wealth of data we need to ensure that the SLS core stage can successfully power each SLS rocket in this long-term hot fire test,” said John Honeycutt, manager of the SLS program at NASA’s Marshall Space Flight Center in Huntville, Alabama. .

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

The Artemis program will begin with a mission to the moon with plans to rely on SLS rockets as a way to send astronauts to Mars.

Teams will continue to assess the data collected from the test. About a month after renovating the main stage and engines, the gas gas barge will move its main house to its next home.

The SLS rocket will be sent to NASA’s Kennedy Space Center in Florida to be assembled and integrated with the Orion spacecraft designed for astronauts.

At Kennedy, teams have already stacked a solid rocket booster in the vehicle assembly building for Artemis I.

Jurzyk said Thursday that the Biden administration supports NASA and its objectives and the Artemis program and agency’s Moon to Mars strategy.

Returned to the moon

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

The diverse team of astronauts includes Joseph Aqaba, Kaila Baron, King Chari, Matthew Dominic, Victor Glover, Warren “Woody” Hobberg, Johnny Kim, Christina Coach, Kegel Lindgran, Nicole Mann, McClean, McKinley Ruby, Jessica Merbie, , Scott Tingle, Jessica Watkins and Stephanie Wilson.

When astronauts explore the Moon’s South Pole, which has never been visited by humans before, they will build on the legacy and science they have acquired during the Apollo program and take it into the new century.

Following the flight of Artemis I, which opened in November, Artemis II will become the lunar crew flyby in August 2023. Artemis III will return astronauts to the moon.

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

The Orion spacecraft can support four crew members and deep deep-space missions, unlike previous crafts designed for short flights.

Orion will dock at a planned gateway The lunar outpost that will orbit the moon. About 250,000 miles from Earth, the gateway will allow easy access to the entire surface of the moon and potential, deep deep space exploration.

The Artemis III Science Definition Team has identified several priorities for this groundbreaking team of Artemis astronauts. These include conducting experimental science on the moon, investigating and mitigating research risks and understanding the origins of elements on the moon’s poles – such as water and other resources used by astronauts.

The agency wants to establish Artemis base camp at the moon’s South Pole by the end of the decade.
