Can someone email me some shuttle first stage trajectory data? I have built a tool to model how an abort system will get away from the SRB debris.
I need velocity (x and y) and altitude. The ascent cue card doesn't have velocity

Edit: Can someone point me to the SODB? I know it is on L2 somewhere, but "search" doesn't find it.

Probably not what you need but can you get anything from Bill Harwood's spreadsheets that he does every mission for CBS/Spaceflight Now?

http://www.nasa.gov/home/hqnews/2009/apr/HQ_09-080_Orion_Heat_Shield.htmlThis press release in regards to the chosen Orion heat shield material (Avcoat ablator) states that the material was used during Apollo and "on select regions of the space shuttle orbiter in its earliest flights. "
I had never heard of this... is it true? If so, where exactly was it used and for what purpose (i.e. why weren't the usual silica tiles or thermal blankets used)?

Hi,
Hope this is in the right section.
I thought a "progres" was not allowed to dock with ISS while shuttle still there (progress 34 docking)?
Thanks

AFAIK, Progress 34 is scheduled to dock on Wednesday, one day after shuttle departs. Progress will be loitering until then.
Recall that STS-127's mission had to be modified in order to allow for the weather-delayed departure. They were originally scheduled to stay attached to ISS one day longer, but shifted some things to after departure in order to accommodate the Progress docking.

I would be interested in the reasons why:
1) the Progress launch could not have been delayed a day or two, and, more generally
2) why it can't dock while a Shuttle is present?
With all the vehicles visiting ISS, and with all the delays they have here and there, this situation will come up again and again. Watch for STS-128 and HTV.

Because one hit MIR

And post launch tile inspections are ...........
Rules like this are made when you are risk adverse.
Progress have had other instances of control problems. But then again, the whole ISS is at risk

1) Correct. Because every significant damage can been seen before docking. Same for late inspections. Same for LON.
2) Yup, so it all begins. I would say
extremely risk averse.
3) Yes, the whole ISS is at risk and this is o.k., but not for Shuttle. Inconsistent. Shouldn't we stop
all docking operations with ISS (Progress and all other vehicles)? Would be safer.

Why doesn't the shuttle bring up a free flying camera and/or imax to film the station/shuttle stack? The pictures would be phenomenal. Bring one up & leave it attached to the truss for servicing by arm or EVA.

IMAX camera only holds 7 mins of film

Good idea. Likely because of cost (and upmass).

No, it's perfectly consistent. Shuttle is more fault-tolerant and has a human crew controlling it, so its approach is safer than Progress. Period.

IIRC, the STS-125 crew only shot 4 "reels" (28 min.) of Hubble. If I had to guess, I'd say another IMAX will be going up before shuttle retirement to capture the completed station during the traditional post-docking 'flyaround'. I sure hope so.
What would *really* be cool would be a mini-satellite with a Hi-Def video camera that could be used for maintenance views of areas not covered by any of the fixed cameras. It could also produce some great gee-wiz shots of the entire station. When not in use, the satellite could simply be 'parked' nearby, or retrieved via the Kibo hatch for battery changeouts. Wait -- of course! Make that two cameras for 3D.
Sorry... just dreaming a bit.

May be a crazy question but has the shuttle fleet ever been photographed together? Would be more of a PR picture than nessessity, but I thought it would be interesting to see if there was a picture out there. I googled for it and nothing came up.
If not, upon shuttle retirement, it'd be nice to see the three side by side for a picture.
Sorry if the question in far fetched and the suggestion crazy (cost money, not needed, etc) just thinking out loud of pictures I'd like to see and possibly have to frame.

No. You completely misunderstood. This has nothing to do with a Shuttle docking. This is about Progress being allowed to dock with ISS only when a Shuttle is not present.
So Progress is is safe enough (redundancy etc.) to dock with ISS, worth tens of billions of dollars, with 6 folks on board. But it is not safe enough to dock when a Shuttle is present at the very same ISS. This is inconsistent. Eighter it is safe enough in both situation or in none. Period. Period.

If a visiting vehicle hits the docked shuttle, she would be very likely unable to reenter (and bring home its crew wich is more than half of the astronauts present on the station). The same accident might as well demage the PMA and station as well...
So you have at least 13 stranded people with 2 soyuz and limited time and resources. Not a desirable situation
