STS-51F pad abort
« on: 11/29/2010 12:03 am »
There HAS to be a video somewhere out there of the first attempt of STS-51F, when the engines shutdown at T-3.
I've seen the ATO video and that's all; youtube has all the other pad-aborts, but no one seems to have video of this one.... any ideas?

I have one or two minutes on VHS, but it is PAL-system. And I can't covert it to post it here. Sorry.

Don't know if you have seen this:



Remember I had seen this as I was browsing video of the 41D abort.  Been reading Riding Rockets, Mike Mullane is hilarious.

That's STS-51 (Discovery) pad abort on Aug. 12 1993. The one requested is STS-51F (Challenger) pad abort on Jul. 12 1985.

Yes,
I've seen it; On  youtube there ALL the pad-aborts, except for STS-51F (Challenger - July 1985)
I just find it unbelievable that there's no footage anywhere.. you can find complete coverage of virtually all the early missions, including the news coverage of the launch and extended coverage due to the ATO.. but the pad abort seems to be impossible to find.. argh.

"Same difference" as DaveS noted three posts above -- those show the STS-51 abort in August, 1993.  The 51-F pad abort occurred eight years earlier, in mid July of 1985.

Wow... I remember *THIS* one clearly!

I was Lead FDO on STS-51, and was in the MPSR for this launch, as I was deploying the ACTS-TOS on the post-Ascent Orbit 2 shift.  I was already wired for the deploy, but when the pad abort happened, I didn't know what to do with all that nervous energy!

I think I was on an adrenaline high for a couple of hours...  but, for some strange reason, when we got the *actual* launch one month later, I was as cool as a cucumber.   8)

Heh, that was a long launch campaign for STS-51.  How wired were you for the attempt three weeks earlier that cutoff inside T-31? ;D

Surprisingly... I don't remember the earlier attempts as much!

I do remember postponing the launch for a few weeks (to the ill-fated August attempt) in order to not fly through the Perseid meteors.  So, maybe the August attempt was extra anxious for me because of the earlier delays.

Who knows... I just remember being fired up and then massively let down.  ;)

Does anyone remember STS-68 pad abort?  I remember I saw this live on NASA TV when I was a kid and being really confused.  Watching it on youtube you can see how much the shuttle is oscillating when the swing arm moves into position.  It looks like you can kind of tell something is up with the engines at startup because you can hear a loud 'pop'.

In the STS-68 abort, it was due to one of the turbopump discharge temps going over the redline limit. Can't remember off hand if it was LH2 or LOX.

Had the issue taken just a bit longer (half s second I think) the redline limit would have been increased and the abort may not have happened. All ended up to be a bad sensor if memory serves.

Isn't that the arm bouncing around?

If you're referring to the 'pop' at 0:32 in the video (~T-9s), I believe that's just the hydrogen igniters going off.

No.. Shuttle stack.  If you watch the close up videos at main engine start, the whole stack rocks a bit.

Huge offset load from SSME's start..  The whole stack only held down at the bottom of the SSRBs.. which while very stiff still flex under the SSME load.. (actually they unload as they are flexed a bit to shuttle side by it's mass when sitting at pad. then when SSME light and offset the mass of the shuttle the SSRB casing straighten out then load other way).   At cutoff.. when offset load is removed.. the whole stack sways back toward the orbiter..  then oscillates for a while.  The SSRBs are big beams(read springs) in essence.. held at one end like a diving board.

Understood - but we're talking about A+45 seconds when the access arm is back in. I guess I can't see that it's still rocking that much versus the bouncing of the arm.

Sorry, you are wrong. The stack does oscillate but no where near that fast. The wobbling in the video is caused by the Orbiter Access Arm swinging back and forth after the fast extend. Look at the hatch frame and the hatch bridge mounted on the right and left walls. They are rocking back and forth on their hinge restraints, in unison and in time with the movements of the swing arm.

I agree it's the access arm rocking, it's just way too fast for it to be the stack.

Watching it again, you have both in play, the orbiter access arm does slam the stop and oscillate a bit, the whole stack is also rocking at the same time if you watch the brief shot of the orbiter right after the shot from the arm.

There HAS to be a video somewhere out there of the first attempt of STS-51F, when the engines shutdown at T-3.
I've seen the ATO video and that's all; youtube has all the other pad-aborts, but no one seems to have video of this one.... any ideas?

The film can now be downloaded in the L2 movie section :)

For some reason when I got to the L2 movie section, I got an error message saying that the file is missing.

Just catching this now, but Ken Hollis posted a video last year on YT that includes the discrete replay of the 51-F pad abort from the OTV 070 camera...if I ever saw this, it was (almost) 30 years ago:


(The replay is just after the 18 minute mark.)

There's footage from several different events in the video; after the 51-F pad abort footage, that short part is from the 41-D pad abort a year earlier.

I assume the STS-41-D pad abort and its fire was the nexus of RSLS aborts and the procedure of the Fire-Ex water being turned on.
There is one of the pad abort videos where the CDR. or PLT. wants the Fire Ex. water on and a sense of urgency is noted in his voice.

STS-51F ABORT TO ORBIT

Quote
STS-51F ABORT TO ORBIT

This video is a reconstruction of the only Space Shuttle launch abort in it's 30 year history, using the NASA TV video alongside simulator and graphics.

Coverage begins at T-20 minutes in the countdown. Film taken on the day shows the inside of the launch control center and the Kennedy Space Center, the crowds waiting for the launch and crew breakfast/walkout/orbiter ingress.

A stylised countdown checklist is used to the zero point in the count.

Multi angles of launch are used along with MOCR footage of the flight director/Capcom/booster officer and simulator/graphics to show different stages of the launch and powered flight stage.

After Main Engine Cut Off, TV coverage continues, with simulator and photos from the mission. The coverage ends before the OMS 2 burn.

All photos/video/audio courtesy NASA
