ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Here's another one showing Atlantis undergoing Orbiter Maintenance Down Period(OMDP)-J1 in Palmdale, CA, between October 1992 and May 1994:
Additions to the orbiter included the improved nosewheel steering system, improved APUs, the drag chute modification to the vertical stabilizer, lightweight...

It was all SWT until STS-6 which introduced the LWT, then back SWT for STS-7. SLWT was introduced on STS-91, the last Shuttle/Mir mission. STS-99 used a LWT as did STS-107. STS-87 was the first launch to do the Roll To Heads Up (RTHU) during the second stage launch.
Another day, another crash, this time here: https://www.dropbox.com/scl/fi/nuqk6ca77j25yqsqwt07c/VS_debugger_D3D9Client4.jpg?rlkey=k77oknl6j0xgw7dagjgpfu7ke&dl=0
Details are: Unpaused, 0.1x time accel, exterior camera view, pre-launch at T-8:47.8, mission STS-109, so OV-102 8th mod, PLB liner...
Another crash, this time on the pad, while paused, same error as earlier though: https://www.dropbox.com/scl/fi/p37tmzmmr59n48i4sf2b8/Orbiter_D3D9Client_SSV_error_paused.jpg?rlkey=jbu2h7hd2m994u6ja4qdzzr5j&dl=0

Well, so far both SLS Core Stages and ICPS's have been flawless. The hydrogen leaks are a Ground Support Equipment (GSE) problem, not a flight hardware problem. The helium problem encountered with the Artemis-1 ICPS was that a ground-side seal got blown into the ICPS helium system and prevented...
Not it wasn't. That was never the plan. SLS never had that capability, it was always short hence the requirement of the Gateway Station in NHRO for Orion to dock to. Gateway would serve as hibernation point for Orion while the crew went to the lunar surface and back again in the HLS lander...
And here's another:
