Anyone know of any chances of a shuttle launch date in the summer of 2009 or 2010?
If this is a trick question you got me - but I'll take it at face value...
3 months in the summer, 12 months in the year... 3/12 = 1/4th, or 0.25, so 25%.

Do we even have a copy of that, L2 fans? Which checklist is it in?
It's in the Ascent Checklist. NASA has published it on their site:
http://www.nasa.gov/centers/johnson/pdf/193883main_ASC_120_F_3.pdf
The LOC/BREAK-UP cue card is on p. 219 of the PDF. Short 'n' sweet, here's what it says:
LOC/BREAK-UP
BEFORE ‘GO AT THROTTLEUP’
• GREEN APPLE
LOCK INERTIA REEL
• JETTISON HATCH
• BAILOUT
• PULL RIP CORD
‘GO AT THROTTLEUP’ TO SRB SEP
• GREEN APPLE
LOCK INERTIA REEL
• VENT
• ‘G’ SPIKE
• JETTISON HATCH
v ALT/SUIT
• BAILOUT (BELOW 40 K)
• PULL RIP CORD
AFTER SRB SEP
v TABS/VISOR/GREEN APPLE
LOCK INERTIA REEL
• GO TO MIDDECK
• VENT
• ‘G’ SPIKE
• JETTISON HATCH
v ALT/SUIT
• BAILOUT (BELOW 40 K)
• PULL RIP CORD

It's a little green ball that activates the emergency O2 flow on the ACES suits. I think mkirk and/or Jim may have fielded this question before...

A spherical valve on the bailout oxygen tank. Even in a hospital, the valves are green. They are spherical on bailout bottles in aviation

No, silly. They follow the card to try to save themselves. The odds aren't great but it beats doing nothing.
Oh, thanks! I saw LOC and assumed the worse.

Sorry. In internal use, LOC means Loss of Control, not loss of crew. Though one can very quickly lead to the other.

With one hung expended booster, does the vehicle have enough control authority to at least keep flying relatively straight, or would it tumble immediately?

How does the crew abort in the event of an SRB SEP failure on one side? This could cause a tumble and LOCV.
There are no written procedures for this. The odds of it happening are extremely remote. If it happened, the abort plan would be decided in real-time, assuming the stack does not immediately lose control (which is likely). If the stack does lose control, the crew will follow the LOC/BREAKUP cue card.
On failure of an SRB to separate, the stack I'm sure would go LOC. The stack is in the vacuum of space, so it might not break up for a while.
First reaction from the crew would probably be to take CSS, then BFS engage. If all the 3 engines are still running, I don't thing the fast sep button would work. The crew would have to shut down the engines then fast sep. Probability of survival would be close to zero.

I am referring specifically to the triangular visual aimpoints at the "close-in" and the rectangle at the "nominal" - the black painted markings used for visual contrast. As far as I know only the White Sands Runways and Edwards Runways have them. They are not at the current TAL sites or KSC, those sites rely on just the PAPIs.
Mark Kirkman
I understand. I am 99% sure KSC and the TAL sights have these visual aids in place. Look at this video.

Dude !!!
Apparently we are not speaking the same language here. You taught this stuff long before I did so I know that you know the subject matter, I think you and I are just talking past each other and may not be interpreting the terminology the same way.
The original question – posted several pages back – was; “what are the black marks on the lakebed as seen during the STA approach to one of the Edwards runways?”
The black marks are referred to as the VISUAL AIM POINT MARKINGS; not to be confused with the PAPI Lights and flashing APILS/Strobes that you see located at the nominal and close in aimpoint locations in this particular video. The BLACK PAINT is used to contrast the surface color so that the crew can find the PAPIs easier during daylight.
Yes the vegetation has been trimmed at KSC, but black paint on the relatively dark terrain around the PAPIs would be less than helpful.
I have attached the Approach Flight Procedures Handbook and SCOM descriptions for clarification…hopefully.
In fact as an aside, I am not sure the strobes are there anymore either..I will have to look at some of the HUD tapes from the more recent daytime missions. Back in the 99 – 2000 timeframe I was at a meeting where one of the topics of discussion included a proposal by the SSP to save money by removing them (the strobes). I only remember this because at the time I was amused at how vigorously Rommel (Kent Romminger)and Wayne Hale debated the relative merits of the strobes in helping the crew locate the PAPIs.

Just to beat this dead horse a little more I found a note in the Maps and Charts Book that says the following about the Edwards Markings:
“All runways (at Edwards) have painted aim points at 6500 ft and 7500 ft except runway 05R, which has only 6500-ft aim point.”
That contradicts what was said in the FPH (flight procedures handbook) graphic I attached in the previous post. The Maps Book should be the most accurate since it is an FDF (flight data file) item.

Does anyone know where there is a good picture or diagram of the place where the Drag Chute is stowed during the flight.
Thanks

See below. Photos show undeployed drag chute at end of mission. A white door, which normally covers the enclosure, had fallen off at launch due to faulty shear pins. The circular device is a mortar which is fired to deploy the chute.
Mission: STS-95 in October 1998. Drag-chute compartment door fell off and impacted SSME#1. Caused no damage to SSME#1 nozzle. Door was never found post-launch.
Video is availabe here(includes KU band antenna deploy sequence):

Here's a question. I've been reading my copy of Jenkins' book that I got for Christmas, and I am really impressed by its level of detail. I was reading over the table outlining which OMS pods and which FRCS modules were used on each flight. Since the latest edition of Jenkins' book is a few years old now, it doesn't contain data on the most recent flights.
According to Bill Harwood's site, Atlantis is flying with LP04 and RP01 and FRC4, but that's all I can find.
Does anyone know which OMS pods and which FRCS module were lost with Columbia?

I rewatched that launch millions of times, and I never noticed the door until now.

The timing of the cuts in the live coverage coincidentally made it less noticeable, but it was a fairly large discussion topic on the day of launch.
