Liftoff is scheduled to occur during a two-hour window that opens Saturday at 2:17 p.m. EDT (1817 GMT).
Replacing the sensor would likely require rolling Artemis 1 off the launch pad and back to Kennedy Space Center's huge Vehicle Assembly Building. The team doesn't think that's necessary or desirable, so they plan to leave the sensor in place and ignore its faulty readings on launch day, NASA officials said this evening.
The Artemis 1 team also looked at several other issues that cropped up during Monday's countdown, including a slight hydrogen leak and a crack in the foam that's part of the SLS core stage's thermal protection system. The leak has been fixed, team members said this evening. And the foam crack requires just"incremental risk acceptance," as does the engine sensor issue.Something else could keep Artemis 1 on the ground Saturday — the notoriously fickle Space Coast weather.
If Artemis 1 can't fly on Saturday, the next opportunity will come on Monday , mission team members said. And the weather looks promising on that day as well, according to Loving. "Basically, the weather looks good," she said."I wouldn't be shocked if there are periods where we are technically red for weather. But the bottom line is that I don't expect weather to be a showstopper for either launch window."" , a book about the search for alien life. Follow him on Twitter
