Here's one, but there will be more...

Thanks, but I need an explanation which designator a window has (as mentioned above)...

Thanks, but I need an explanation which designator a window has (as mentioned above)...

In the flight deck picture above there are 6 windows which are labeled from left to right (window 1, 2, 3, 4, 5, and 6). Window 3 and 4 would be the front windows and are regarded as the +X windows because they look directly forward. Window 3 is front of the Commander’s seat with windows 1 and 2 to his/her left (-Y direction)and window 4 is in front of the Pilot with 5 and 6 located to the right (+Y direction).

For the overhead windows, window 8 is located behind the Commander and window 7 is behind the Pilot. The overhead windows would be regarded as the -Z windows.

Looking into the payload bay from the flight deck, you would have window 9 on the left and 10 on the right (looking in the -X direction).

How is spacehab loaded? I assume the experiments/supplies are loaded on the ground in the operations and checkout building and then the whole lot added as a payload when the orbiter is at the pad but is this correct?
Thanks.

Actually incorrect

Spacehab modules only went through the O&C on their first flights (SH-01&02). The rest (15 flights) went to the pad, (except SH-03 and STS-107 went to the OPF).

Experiments/supplies were either loaded in module at the SPPF ( Spacehab Payload Processing Facility) or at the pad.

The module was accessed at the pad by use of a winch in the middeck which lower hardware and personnel through the airlock and tunnels. The system was called MVAK. Module Vertical Access Kit. MVAK was actually developed for Spacelab modules, for installing life science subjects. Spacehab actually used it more time and more hardware.

Tech using MVAK

to the startracker: where is it at the pic above? Is it the small circle left of window 8?

@all

Thanks very much for your detailed help!

And of course for putting those designators into the pic above...

Hi,

I just saw some launch vids of the shuttle where you can listen to CAPCOM transmission. Shortly before MECO their comes a command from CAPCOM saying...

"...Go for the "posess" (rem.: sorry, but I cant identify this word), go for the pitch..."

What does that command mean exactly?

Thanks very much!

He says: "Go for the PLUS X", which is a maneuver they do just after ET separation that allows them to take pictures of the tank, I believe.

"Go for the plus X" - after ET SEP, the orbiter performs an automatic -Z ("up") maneuver to separate from the tank. Shortly after that, the crew performs a manual +X ("forward") maneuver to sweep the ET umbilical well camera along the ET at close range to get good photos of the condition of the ET. The manual +X is not performed in the event of certain malfunctions, so a "Go" from MCC is required to perform it.

"Go for the pitch" - after the +X maneuver the crew photographs the ET using handheld cameras through the overhead windows. To point the windows at the ET, the crew performs a manual pitch maneuver. This is also not performed under certain conditions so it also requires a "go".

Loss of power on both DC buses, thats an interesting one.
mb

Not "both" - I said "any two" buses. There are three.

Also, isn't is actually the AC busses that drive the ET umbilical doors, not DC?

The AC inverters are powered by the DC buses. AC1 from Main A, AC2 from Main B, AC3 from Main C. Lose a DC bus, lose the corresponding AC bus.

If anyone's familiar with the manifest...assuming it's been done already, what is the first tank to be assembled with the new modifications (omition of PAL ramps/restructure of the IFRs), and which mission is it currently assigned to?

kimmern123 · « **Reply #155 on:** 11/29/2007 06:27 pm »

I think it will be ET-128, flying on STS-124 in the spring

Viewing/Listening HELP please! I'm traveling down for my second launch this upcoming week and would love to listen live to the countdown as I view. Using scanner or radio does anyone know if there is a non-delayed broadcast? Last launch (116) would have been have been much more enjoyable if i weren't listening to a 10sec delay. MUCH THANKS!

Welcome to the site...Good place to ask would be here: http://forum.nasaspaceflight.com/forums/thread-view.asp?tid=10458&start=1 - hopefully (likely) someone will be able to help, though people will respond on the thread, not e-mail.

On the radio... 920 AM has a live broadcast of NASA TV.
