I kept reading about the shuttle not flying till the leak was found, and after a "Thermal Blackout Period" What is this blackout period ?ThanksDuane

It's called the "beta angle cutout" and here is a link that provides some good information. Google is your friend.http://sci.tech-archive.net/Archive/sci.space.shuttle/2006-08/msg00226.html
OMS Assist capability was implemented with the OI-26 software, I will have to check which flight did it first. From a quick search it looks like it was STS-90 but I seem to remember being in the simulator with John Young (yes name dropping) the night before STS-92 because of cg concerns he had with the OMS assist and subsequent aborts - I thought that was the first flight but I will have to double check I just don't remember but wiki is saying STS-90. STS-90 might have tested the concept prior to an actual heavy station mission.Mark KirkmanP.S.Yep, I checked my notes and it was indeed a test objective on STS-90 which was the neurolab flight and not a station mission.
What is the mechanical component that allows the shuttle, ET and SRB's to complete the "roll over" technique during launch. I would assume that it is the elevon/ailerons or tail of the orbiter.
I have researched this question (curious myself):#1 STS-1 (102) days on Pad#2 STS-122 (89) days on Pad (Eco Sensor issue)#3 STS-127 (85) days (if launched on 7/11)Note: STS-35 had (109) "non-continuous" days split between Pad-A/B but briefly rolled back to VAB (hydrogen leaks).

Otherwise, as Murphy dictates, the next launch will invariably slip into the long awaited trip for which you purchased non-refundable tickets!

Non-refundable tickets... vacation... and now a potential Shuttle launch!
Hi guys, a question about DPS :The DPS seems to allow switching between some of the major modes (OPS 201 and 202 for example), but apparently it seems impossible to revert back from some modes to the previous one. For example it seems impossible (if you have a look at the DPS dictionnary for instance) to revert back to OPS 303 once OPS 304 was entered.So three questions in one :1) is it possible to go back from OPS 304 to OPS 303 for example (and all the other similar configurations) ?2) if yes how ?3) if no : how would they do if someone entered OPS 304 too early by mistake ?Thanks in advanceNephi

I have been out the training business for a while, so don't trust what I say 100%.On going to 304 by mistake, I am assuming you haven't done the deorbit burn yet. I think you could somehow take your time and if nothing else go back to OPS 2. BFS engage could be an option if it didn't also go over. I don't remember if BFS does what is called a DK listen to the command to PASS to go the 304, or if the crew has to take if over separately. Please forgive me if this is all lies. Even in my prime, I wasn't a DPS instructor. But I used to know this stuff pretty good as a control/prop instructor.I do know going in and out of the OPS 2 mode to do an orbit burn is two way. I can't remember the number of the modes. I think it is 201 and 202.Danny DegerWhere did you get a DPS dictionary. Make sure it is on L2. I bet Chris would trade you some L2 time for a DPS dictionary if he doesn't already have on.

As for OPS 201 <-> OPS 202 this is indeed two-way. 201 is for burns, 202 is for payload bay doors.
