tater Posted June 19, 2022 Share Posted June 19, 2022 Not really being reported, but the SLS WDR has sort of started. They powered up this afternoon. Orion is powered up by now. Tomorrow really busy as well. Quote Link to comment Share on other sites More sharing options...

StrandedonEarth Posted June 20, 2022 Share Posted June 20, 2022 Also a grass fire near the H2 flare stack, I hear. Someone forgot to get out the weedwhacker… Quote Link to comment Share on other sites More sharing options...
Scotius Posted June 20, 2022 Share Posted June 20, 2022 So, still not a clean attempt so far - but hopefully nothing major will pop out. Quote Link to comment Share on other sites More sharing options...

Someone forgot to get out the weedwhacker… Zeesh! https://www.space.com/news/live/nasa-artemis-1-moon-mission-updates "Nail added there are more issues forthcoming: there appears to have been a pressure limit exceeded during fueling in the liquid oxygen for the upper stage, and a small grass fire has emerged nearby the launch pad. It is unclear what the grass fire was caused by, and agency officials have their cameras on the area to monitor the smoke coming out of the grass. It is unclear what impacts these issues would have, if any" Edited June 20, 2022 by JoeSchmuckatelli Quote Link to comment Share on other sites More sharing options...

Beccab Posted June 20, 2022 Share Posted June 20, 2022 Issues have been solved (the fire is being left on its own), currently at the T-10 mins hold Quote Link to comment Share on other sites More sharing options...

tater Posted June 20, 2022 Share Posted June 20, 2022 (edited) Polling on the option to continue the count to T-9 seconds—which is where they plan to stop, since that's when they light the RS-25s (?). They think they can mask a valve issue sensors to continue the count, since the small H2 leak is not a problem given that they will not be lighting the engines anyway. Would be ideal if they can do this, then work the now understood GSE issue at their leisure. Edited June 20, 2022 by tater Quote Link to comment Share on other sites More sharing options...
tater Posted June 20, 2022 Share Posted June 20, 2022 T-7 minutes and counting 4:40 milestone came and went Masked issue passed 33 second passed 29s hold/cutoff Not sure what that means in terms of what if anything needs doing Quote Link to comment Share on other sites More sharing options...
tater Posted June 20, 2022 Share Posted June 20, 2022 Safing vehicle. They expected the vehicle to stop at T-29 because of a flag they knew about (presumably they could not mask that). Quote Link to comment Share on other sites More sharing options...
Beccab Posted June 21, 2022 Share Posted June 21, 2022 Great attemp overall! WDR#5 is still a concrete possibility given the T-10 minutes issues, but it definitely got much closer than the last times Quote Link to comment Share on other sites More sharing options...
tater Posted June 23, 2022 Share Posted June 23, 2022 NASA declaring WDR complete. Gottagetthereitis, or sensible choice? If it works, then we'll never know. Glad it's not my call. Quote Link to comment Share on other sites More sharing options...

Glad it's not my call. They probably figure that they'll be enough stops and aborts on the first attempt so they really don't want to use up the finite number of times they can refuel the tank. Just take it down to T-21 and fix it then. Quote Link to comment Share on other sites More sharing options...
Beccab Posted June 23, 2022 Share Posted June 23, 2022 Important to note however that in case the countdown reaches RS-25 ignition before having an abort, SLS will have to rollback to the VAB for maintainance Quote Link to comment Share on other sites More sharing options...

Yeah, it's likely not a big deal—but it's the sort of thing that will look bad if something goes really wrong—even if doing another WDR might not have caught it. It's tough on the people pulling the trigger. Quote Link to comment Share on other sites More sharing options...
