What’s next for NASA’s moon rocket – Brospar Daily News

Over the next few days, NASA engineers will address the hydrogen leak that grounded the moon rocket during Saturday’s second launch attempt. They need to figure out if they can fix the gasket that pumps supercooled fuel into the rocket on the pad, or once they get it back to the vehicle assembly building. Both locations have their advantages and challenges. “There is a risk-risk agreement. By doing it on the mat, you’re exposing it to ambient conditions, and we have to build an environmental enclosure to do that. If we do it in a vehicle assembly building, the vehicle assembly building is an environmental enclosure. However, we were unable to test this rapid disconnect at cryogenic temperatures,” said Mike Sarafin, NASA’s Artemis mission manager. Regardless of the leak, a system reset in the VAB was required before another launch attempt could be made. The mission’s first objective, the Artemis program, is focused on testing the SLS rocket and the Orion spacecraft that will carry astronauts. So while no one was on board, the data collected was critical to safety as all four astronauts sat aboard the 322-foot SLS. I know people understand that these are safety issues first. Sometimes you just have to make the decision to postpone,” said Julie Brissett of UCF’s Florida Institute for Space Research. So now, how long to postpone depends on the progress of repairing the leaky joint. “We will leave when we are ready. On Saturday, NASA Administrator Bill Nelson stressed that cleaning was part of the process. “We leave when we are ready.” We won’t go that far, especially now for a test flight because we’re going to stress test it and test the heat shield and make sure it’s in good shape before we put four people in it. “It really poses no risk to the timeline of future Artemis missions,” Nielsen said: Artemis II is still scheduled for 2024, and Artemis III is still scheduled for 2025. “Two scrubs cost a lot less than one failure,” Nielsen said. . .

Over the next few days, NASA engineers will look into the hydrogen leak that caused the lunar rocket to crash on the moon. The second attempt was launched on Saturday.

They have to figure out if they’re going to fix the joint, where the supercooled fuel is pumped into the rocket on the launch pad, or once they bring it back to the vehicle assembly building.

Both places have their advantages and challenges.

“There is a risk-risk agreement. By doing it on the mat, you’re exposing it to ambient conditions, and we have to build an environmental enclosure to do that. If we do it in a vehicle assembly building, the vehicle assembly building is an environmental enclosure. However, we were unable to test this rapid disconnect at cryogenic temperatures,” said Mike Sarafin, NASA’s Artemis mission manager.

Regardless of the leak, the system must be reset in the VAB before another start attempt can be made.

first objective of the mission

The first mission of the Artemis program is to test the SLS rocket and the Orion spacecraft which will carry astronauts. So while no one was on board, the data collected was critical to safety as all four astronauts sat aboard the 322-foot SLS.

“Even when people are disappointed, there is understanding. I know people understand that these are security issues. Sometimes you just have to make the decision to postpone,” said Julie Brisset of UCF’s Florida Institute for Space Research.

So, for now, the length of the delay will depend on the progress of the repair of the leaky joint.

“We leave when we are ready”

On Saturday, NASA Administrator Bill Nelson stressed that cleaning was part of the process.

“We leave when we are ready. We’re not going to go that far, especially now for a test flight because we’re going to stress test it and test the heat shield and make sure it’s okay.

For now, Nelson said, this poses no risk to the timeline of future Artemis missions: Artemis II is still scheduled for 2024, while Artemis III is still scheduled for 2025.

“Two scrubs cost a lot less than one failure,” Nelson said.
