Key Elements of NASA’s Space Launch System Built and Tested in Mississippi

Parts of the world’s most powerful rocket are assembled and tested in Mississippi as the United States returns to the moon. Americans have been traveling in space for 60 years, but much of the work to get there begins in Hancock County. Key elements of NASA’s Space Launch System, or SLS, are being built and tested at the Stennis Space Center. Stennis has been at the center of US space vehicle development since the Apollo missions. The centre’s booth B-2 was used to test the stages of the Saturn V rocket that took Americans to the moon. And all of the Space Shuttle’s main engines have been tested at Stennis, throughout the 34-year program. RS-25 engines, with all their history – and now the technology added – will power Artemis missions, with over 2 million pounds of thrust. “That engine flew in space. What we do with that engine at this point, we reuse it, modify it. We added extra propulsion, power to it,” said Michael McDaniel, managing director. Aerojet Rocketdyne SSC. They are renovating and modernizing the RS-25 engine and making it part of the most powerful rocket in the world. “We added about 40,000 pounds of extra thrust to it and reduced the cost of that. about 40%, “McDaniel said. Four of the RS-25s will be laid out at the bottom of the SLS, which is also equipped with two powder thrusters. The main stage and the 212-foot-high upper stage are topped by the vehicle. Orion Crew. Three Artemis missions are defined. Artemis 1 is an unmanned flight that will test the space launch system and the Orion spacecraft together. It is expected to launch later this year. Artemis 2 will be a crewed mission, sending astronauts into orbit around r of the moon and the furthest point in space. In 2024, Artemis 3 will fly. woman and the next man on the moon, ”McDaniel said. But before all that, back in Mississippi, the massive center stage was tested earlier this year with a hot-fire green track at the B-Test complex. And the engines are still being tested. “This is the A-1 test facility. This is one of the RS-25 engines that you saw this morning in the assembly building,” said Ryan Roberts, bench manager. test Stennis B-2 said in a recent interview at the Space Center with 16 WAPT News. “Transport it here on a truck, we lift it, put it in the test bench with a crane. It’s put in this test position. It’s a drive axle here, so it’s going to come back here. underneath us, well below that engine deck at the bottom, is a flame deflector, “said Roberts. Fifteen engines from the shuttle program will power the first four Artemis missions, along with a very special engine for those on board. Stennis. ”This 2063 engine was built at Stennis facility, Mississippi facility, Mississippi workforce, employees, Mississippi paperwork, planning. . and that engine is going to be on Artemis 2, bringing the first humans to the Artemis mission, ”McDaniel said. The next generation of RS-25 engines will be built in Mississippi and created with advanced manufacturing techniques, including 3D printing. This is the first in a series of special reports by Troy Johnson of 16 WAPT and chief photographer Lamonte Brown.

Americans have been traveling in space for 60 years, but much of the work to get there begins in Hancock County. Key elements of NASA’s Space Launch System, or SLS, are being built and tested at the Stennis Space Center. Stennis has been at the center of US space vehicle development since the Apollo missions.

“That engine flew in space. What we do with that engine at this point is we reuse it, modify it. We added extra propulsion and power to it,” McDaniel said. , General of Aerojet Rocketdyne SSC. director.

They renovate and improve the RS-25 engine and make it part of the most powerful rocket in the world.

“We added about 40,000 pounds of extra thrust to it and we reduced the cost by about 40%,” McDaniel said.

Four of the RS-25s will be arranged at the bottom of the SLS, which is also equipped with two solid rock thrusters. The 212-foot-high main floor and upper floor are topped by the Orion crew vehicle.

Three Artemis missions are defined. Artemis 1 is an unmanned flight that will test the space launch system and the Orion spacecraft together. It is expected to launch later this year.

Artemis 2 will be a crewed mission, sending astronauts into orbit around the moon and the farthest point in space.

In 2024, Artemis 3 will fly.

“This one is going to put the first woman and the next man on the moon,” McDaniel said.

But before all of that happened, back in Mississippi, the massive center stage was tested earlier this year with a hot fire green run at the B-Test complex. And the engines are still being tested.

“This is the A-1 test facility. This is one of the RS-25 engines that you saw this morning in the assembly building,” said Ryan Roberts, bench manager. Stennis B-2 test in a recent space center interview with 16 WAPT News.

“Transport it here on a truck, we lift it, put it in the test bench with a crane. It is placed in this test position. It’s a driving bridge here, so it’s going to come back here. Below us, well below that the engine deck below, is a flame deflector, ”said Roberts.

Fifteen engines from the shuttle program will power the first four Artemis missions, along with a very special engine for the people of Stennis.

“This 2063 engine was built at the Stennis facility, the Mississippi facility, the Mississippi workforce, the employees, the Mississippi documents, the planning. We assembled it here … have it. tested on the test bench, certified in flight, tested first time, and this engine is going to be on Artemis 2, carrying the first humans on the Artemis mission, ”McDaniel said.

The next generation of RS-25 engines will be built in Mississippi and created with advanced manufacturing techniques, including 3D printing.

This is the first in a series of special reports from 16 WAPT’s Troy Johnson and chief photographer Lamonte Brown.
