Mark: thanks for the answer. It was something that had been on my mind on and off again for a few years. In my mind up until now was that the "north" that the MCC PAO stated was in relation to the orbiter coordinate system where "north" was +X.Another DPS question: Did MM104 OMS-1 MNVR EXEC take in account the additional dV of the MPS propellant dump when calculating the dV targets?
I'm curious about one aspect of the radiators inside the payload bay doors. When the orbiter was flying on its own (i.e. not docked to Mir or ISS), was the payload bay oriented away from the Sun as often as possible to minimize Solar heating of the radiators? When the bay was facing the Sun, did the radiators lose some of their cooling efficiency? I'm not well versed in the underlying physics of the radiators.Thx
I’ve tried searching but to no avail; I recall somewhere on here, there was a dramatic photo of the forward fire team “caught” outside their bunker during launch.. I think the story was that a hold was called for T-31 so they went outside.. then the hold was cancelled and they didn’t have time to get back inside.. there was talk on here of which launch it was but idk if it was ever determined ?
I'm not sure if it was ever identified as to which mission it was, but here is the photo...https://www.thedrive.com/content-b/message-editor%2F1642726676274-lzajden.jpeg?auto=webp&optimize=high&quality=70&width=1440
Yes, the carrier vehicle is outside the pad's perimeter fence. This was M-113/Hard Top One's astronaut rescue vehicle and team (I think Unit #HE-704-080) on station at A/B 4, just under a mile from the shuttle on Pad B, during the launch of STS-26/Discovery in Sept. 1988. I think the photo seen is one that had been autographed by one of the 12-member astronaut pad rescue teams that Bob had gotten from me long ago.
