STS-125 Hubble Repair Mission (Atlantis) [May 2009?]

[MeteorWayne]

<p>scribblenotes:</p><p>current plan is to</p><p>1. further investigate failure</p><p>2. prepare for switching to CU/SDF side 5. That will be later in the week since they must test on ground duplicate system. The Device takes inputs from 5 instruments and formates it for transmission at ~ 1 MB/sec to ground.</p><p>3. Plan to take spare CU/SDF on hround for testing and take it up on STS-125. It goes in Elec Bay # 10.</p><p>This will lead to a "several month delay" in the mission, maybe 3 months.</p><p>Some additional training required,but not much. It should only add about 2 hours to one of the spacewalks as access is not difficult and it is designed to be replaced. All 5 EVA's were full, so somthing will have to be shifted around.</p><p>Reason for replacement is that if they left Hubble obserating with current side B only, there are several single point failures that could end the mission.</p><p>Earth based replacement has been in a more protected environment (No radiation, no temp cycling, no vibration, etc) so should be in good shape. It won't be available until at least the first week of Jan. Mid Feb seems reasonable estimate for mission.</p><p>It would have been worse if this had occurred just after we left the Hubble, since it would be left with the single point failures, so the timing of the failure was actually good sice we can replace it. The spare was built and on the ground as the possible failure was anticipated over 20 years ago. First one did pretty good considering it has lasted 18 1/2 years in space.</p><p>Weight issue on launch? Not at all, in fact it will replace some ballast that had been planned to be carried to balance CoG.</p><p>MW</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>&nbsp;So the jist I get from TFT is that it isn't likely to be ready to go until mid-febuary, but they may opt to launch STS-119 (targeted for Feb 12th) on time, and move STS-125 to a slot later in spring when they can't go to station anyways (beta angles).Since we seem to be looking at a 4-6mo delay, will they destack Atlantis and take it back to the OPF? How may highbays are currently avalible to hold stacks, 2?&nbsp;Thanks <br />Posted by emerrill</DIV><br /><br />This question was asked and answered, but I didn't hear it, since I was gatting booted off my computer due to a work emergency for Ann. Sorry.</p><p>MW</p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John. Monsters.

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>They would have to replace it i would of thought. With no redundancy, all the work during STS125 could go to waste if the B side fails <br />Posted by bobble_bob</DIV></p><p>Precisely correct.<br /></p> <div class="Discussion_UserSignature"> </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>According to TFT, the mission has been delayed until 2009. Next mission will be STS-126 on Nov 16th:&nbsp;http://www.floridatoday.com/content/blogs/space/2008/09/nasa-delays-hubble-mission-to-2009.shtml <br />Posted by emerrill</DIV></p><p>We are driving toward a STS-126 launch on Nov. 14th<br /></p> <div class="Discussion_UserSignature"> </div>

 

[shuttle_guy]

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>So will STS-125 roll back to the VAB, and STS-126 move to LC-39A? My understanding is that LC-39B is not maintainted at a level to support a standard launch - is that true? Obviously now Constelation will not get the pad until around March of 2009, so I assume that will lead to a 4-5 month delay in the test flight? <br />Posted by emerrill</DIV></p><p>Yes, the STS-125 stack will move back to the VAB. We will load hypergolic prop into the STS-126 stack at pad B then move it to pad A for launch. LC39B is ready to support a Shuttle launch, as it would have to be for a rescue mission. However the Pad Payload Changeout Room (PCR) at Pad B has not been maintained since was is not be to used again. This prevents a payload from being installed into an Orbiter at pad B.<br /></p> <div class="Discussion_UserSignature"> </div>

However I expect the STS-125 flight will end up flying in May with STS-127 as the rescue vehicle. That gives the Ares 1X guys e bigger umbrela.....that is the May STS-125&nbsp;launch pushes their (ARES 1X) launch off&nbsp;more months than it will be delayed for a STS-125 Feb. launch.</p> <div class="Discussion_UserSignature"> </div>

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>But the next ISS mission will go up earlier.&nbsp; This is a total reshift in the manifest, and I doubt even today the full repercussions can be understood. But then the backup pad (B) will need to delay the conversion to Ares Orion.There's a lot of balls in the air at the moment.Give them more than 24 hours to look at things. <br />Posted by MeteorWayne</DIV></p><p>&nbsp;</p><p>The next ISS mission will only fly, at best, 2 days earlier that it would have. The STS-119 mission slips a month or so.&nbsp;<br /></p> <div class="Discussion_UserSignature"> </div>

 

[shuttle_guy]

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>That's taking it a bit of extreme logic. Even if you took every peice up there, you only have time to replace so many - so you replace what is broken at the time. There is a risk/cost tradeoff to everything. This could have happened theday after landing, they just got lucky it happened now.Cost wise, you are likely talking a very small amount, because most the work of prepping the second orbiter applies to the next launch of that orbiter. <br />Posted by emerrill</DIV></p><p>I agree with all of your post......it is precisely correct.<br /></p> <div class="Discussion_UserSignature"> </div>

Most likly we will not destack.</p> <div class="Discussion_UserSignature"> </div>

Other than the time testing the replacement why delay until next year?

There's no way to add another EVA, so something will have to give.

Oooo, I see that the STS-125 stack appears to be targetted for rollback on the 20th. My wife and I are still planning on going down the week the launch would have been, so I'll still get to see them both out there it looks like. <div class="Discussion_UserSignature"> </div>
