NASA’s Artemis 1 launch attempt hinges on solving engine problem

UPDATE: Get excited! NASA officials said in an update Tuesday that the next Artemis 1 launch attempt will take place on Saturday, September 3 from Kennedy Space Center. The launch window opens at 2:17 p.m. Kennedy Space Center’s countdown is still at T-40 minutes, where the last hold went into effect Monday. NASA officials have been working on the issue with Engine #3 ever since. They seek to see what is wrong and how to fix it. “Even in the testing campaign, they never even got to the point where they had their issues yesterday. So it’s probably not that unexpected,” Florida Tech’s Don Platt said. The impact of the technical problem is known, but the fix is ​​still a question mark.” The coolant was not flowing through the engine and so it’s probably some kind of valve problem. It really depends on how which part of the engine they can access. While still on the pad,” Platt said. Even though the RS-25 engines were used during the shuttle program and NASA engineers are familiar with them well, the SLS rocket stack has a different design, so if they can’t get to the root of the problem on pad 39B, it’s back to the vehicle assembly building and weeks of delays. But this is a complicated new rocket in a program with lofty aspirations. There are human bases on the moon and people are working there,” said Julie Brisset of the Florida Space Institute at the University of Central Florida.

“People won’t remember there was a scrub on a certain day where there are human bases on the moon and people working there,” said Julie Brisset of the Florida Space Institute at the University of Florida. central.
