Along with a leak-free fueling test, NASA needs Space Force clearance to press ahead for a third launch try September 27.

The Space Force Eastern Range is evaluating a waiver request from NASA to enable a third launch attempt by the end of the month.

Hydrogen tank. that material is at a negative 423 degrees fahrenheit, right? so there is a line, this cryogenic line that is highly engineered and there is a coupler that couples it to fill the sls, and that disconnect, as they call it, that quick disconnect, is itself a high technology, right, thats been engineered over more than a decade. and for some reason, it is not sealing properly and there is a hydrogen leak. and so this isnt the first time this particular failure has occurred in terms o...

>> it was pretty clear that we were not going to be able to work our way through it like we did on monday in terms of the managing of the leak. every time we saw the leak it was a large leak that immediately exceeded our flammability limits. >> charlie blackwell thompson calling for a scrub for the day. >> testing it under cryogenic conditions or move it inside the assembly building from the elements of florida while having that her access to fix it. for now it remains here and the clock frozen....

NASA has delayed the launch of its Space Launch System again, following another scrubbed attempt in late August. This time, the delay was caused by a hydrogen leak that engineers failed to fix during several troubleshooting attempts.

Informal remarks to them and told them that they believe that a rollback, a full rollback of the sls rocket in orion capsule is going to be necessary in order to fix the problem that caused the scrub today. we expect official confirmation of that to come likely during the 4:00 p.m. press conference that nasa officials are going to give to the press this afternoon. but behind the scenes, this is what the nasa leadership is telling some of the vips in attendance. that a rollback is likely. so what...

We right now have another attempt on the schedule for monday, but well just see what happens when they analyze the data. one of the constraints as the flight determination system. where this rocket to veer off course during the launch they would destroy it. that has an independent battery system thatis has an independent battery system that is only good to the middle of this coming week. unless they get off on monday or tuesday, then they will have to bring it back to the assembly building here ...

Try to make some fixes in a short period of time. they do have a two-hour launch window on monday. thats a possibility. they have another launch window on tuesday but its only like 30 minutes long, thats really not what nasa wants. so if they cannot get this fixed on the launch pad by either monday or tuesday, then its really not good, because then, sara, they have to take this entire stack, all 322 feet of it, they have to put it back on the crawler and take it all the way back four miles to th...

Many, many efforts to solve that problem remotely. nasa does not light to walk anyone out onto the launchpad. once a spaceship is out there and habitually do not want that. we tried several remote measures. they could not get a fixed. eventually, they did grab that when there was about two and a half hours before the launch window could begin. at this hour, bill nelson -- the big question is whether or not they are going to have to roll that thing back into the assembly building. you can see it ...

What nasa calls -- this is very nasa lingo, they call them the soft goods on the seal. so essentially this is the seal where thundereres a pump, they pumping super cold liquid hydrogen into the main tank, there was a leak there, and those soft goods, that seal was da damaged. now they need to fix it. the big question now is can they fix it at the launch pad or do they need to roll it back to the vehicle assembly building, which is four miles away. if that happens, it is a several weeks long dela...
