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

MeteorWayne · Oct 30, 2008

Bottom line on the teleconference, the earliest the unit ready for the repair mission will be delivered is April, so the earliest STS 125 mission might be May.The flight unit had been partially disassembled in support of previous missions to put parts on an engineering unit. It will take plenty of testing to make sure it's ready, meanwhile Hubble is back on line, so there's no rush, other than the downstream effects on the ARES/Constellation fufture, but we knew tose dates were going to slide anyway, so I see it as a good tradeoff. <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

Replying to: <DIV CLASS='Discussion_PostQuote'>So from the posting over at TFT, they are saying that the destack would (will) be a complete disassembly of the stack... is that correct? They are saying it would be because the SRBs have been in the stacked config too long, and to hand over the MLP to the Constellation program for Ares 1X. Do the SRB segments (a 'fueled' segment, not the casing) become completely unusable after some amount of time, or do they just have to be 'reconditioned' in some way before they can be restacked? Also, is there something special about the MLP that the current stack is on, that Ares 1X needs that one instead of the currently unoccupied one (or have they stated stacking for STS-119 - I saw it was moved into high bay 1 when I was there a few weeks ago)? Article here: http://www.floridatoday.com/content/blogs/space/2008/10/listen-watch-live-hubble-faces-delay.shtml Posted by emerrill</DIV>Well I guess the disassembly of the SRBs was incorrect. Based on the notes if seen from the STS-126 press conf, OV-104 will be destacked, and OV-103 will be attached for STS-119 in Febuary. After STS-119 is off the pad, the MLP will be turned over to Constellation. <div class="Discussion_UserSignature"> </div>

Posted by emerrill</DIV>By turning over the MLP to Constellation do you mean they will start modifying SLC39B?  How can they do that prior to the Hubble mission?  Don't they still need the STS-400 capability?

Posted by trailrider</DIV>The MLP is the Mobile Launch Platform, which the shuttle sits on during launch and is carried to and from the VAB on the crawler. There are three of them; they want to use MLP-1 for the transition, and that is what is currently being used for 125 turned 119. So after 119 launches they can work on that. But the pad itself will wait until after 125 has launched. <div class="Discussion_UserSignature"> -Ben </div>

Oct. 30, 2008 RELEASE: 08-280 NASA MANAGERS DELAY HUBBLE SERVICING MISSION WASHINGTON -- NASA managers have announced that they will not meet a February 2009 launch date for the fifth and final shuttle mission to the Hubble Space Telescope. The decision comes after engineers completed assessments of the work needed to get a second data handling unit for the telescope ready to fly. The unit will replace one that failed on Hubble in late September, causing the agency to postpone the servicing mission, which had been targeted for Oct. 14.  "We now have done enough analysis of all the things that need to happen with the flight spare unit to know that we cannot be ready for a February launch," said NASA's Astrophysics Division Director Jon Morse at NASA Headquarters in Washington. "The February date was an initial estimate, assuming minimal hardware preparations and test durations that are no longer viewed as realistic. We've communicated our assessment to the Space Shuttle Program so it can adjust near-term plans. We will work closely with the Shuttle Program to develop details for a new launch opportunity."  "Getting ourselves in a position to be ready to launch the Hubble mission will involve many steps, and a significant one took place earlier today," said Hubble Program Manager Preston Burch at NASA's Goddard Space Flight Center in Greenbelt, Md. "We held a flight certification peer review meeting where every aspect for doing this effort -- the inspections needed, all the tests to be conducted, the certification process and the final flight preparations -- was examined. The conclusion was that we indeed have a very good plan in place."  The Hubble flight spare, known as the Science Instrument Command and Data Handling system, has been at Goddard since it was originally delivered as a back-up system in 1991. The unit currently is undergoing testing and examination to identify and correct any problems. That work will continue until mid-December.  The unit will then undergo environmental assessments that include electro-magnetic interference checks, vibration tests, and extended time in a thermal vacuum chamber. Environmental testing is anticipated to run from mid-December to early March 2009. Final testing will be conducted on the unit, and delivery to NASA's Kennedy Space Center in Florida is expected in early April.  "The equipment we are dealing with has a flight-proven design," said Burch." The original unit on Hubble ran for more than 18 years. We have a lot of spare parts if we encounter problems, and we have most of the same test equipment that was used with the original unit. We also have a lot of experience on our Hubble electrical replica, which uses the engineering model data handling unit."  The vast majority of the flight hardware, tools and support equipment that will be used during the mission will be stored at Kennedy. A small amount of new work such as re-lubricating the latches on the Soft Capture Mechanism and testing the motors on the Flight Support System will be conducted. The Wide Field Camera 3 will remain in its carrier. The Cosmic Origins Spectrograph is in a special double-layered purge system in its shipping container to help support its environmental needs. The new batteries to be installed during the mission are in cold storage at Goddard and will be returned to Kennedy in 2009.  In the meantime, science observations on Hubble that had been suspended continue to move toward standard operations. The current primary camera on the telescope, the Wide Field Planetary Camera 2, was brought back online. On Wednesday, calibration images with the Advanced Camera for Surveys' Solar Blind Channel were completed. Regular science observations resumed Thursday, and the first science image from the camera was released.   <div class="Discussion_UserSignature"> </div>

Status ReportScience observations using Hubble’s Wide Field Camera 2 and the Advanced Camera for Surveys’ Solar Blind Channel began last week, and a full schedule of observations are planned for this week. Hubble engineers remain on track to restart the NICMOS cryocooler around mid-November. Hubble engineers completed initial testing on Side B of the spare Science Instrument Command and Data Handling (SI/C&DH) system, currently in the cleanroom at NASA’s Goddard Space Flight Center. Over the weekend the team continued troubleshooting the intermittent problem with Side A. <div class="Discussion_UserSignature"> But the Krell forgot one thing John. Monsters. Monsters from the Id.

There shoul be an update in 2 weeks as to how the checkout of the replacement avionics is going Posted by shuttle_guy</DIV> Official Announcement:RELEASE : 08-320 NASA Sets Target Shuttle Launch Date for Hubble Servicing Mission HOUSTON -- NASA announced Thursday that space shuttle Atlantis' STS-125 mission to repair the Hubble Space Telescope is targeted to launch May 12, 2009. The final servicing mission to Hubble was delayed in September when a data handling unit on the telescope failed. Since then, engineers have been working to prepare a spare for flight. They expect to be able to ship the spare, known as the Science Instrument Command and Data Handling System, to NASA's Kennedy Space Center in Florida in spring 2009. STS-125 is an 11-day flight featuring five spacewalks to extend Hubble's life into the next decade by refurbishing and upgrading the telescope with state-of-the-art science instruments and swapping failed hardware. Scott Altman will command STS-125, with Gregory C. Johnson serving as pilot. Mission specialists are veteran spacewalkers John Grunsfeld and Mike Massimino, and first-time space fliers Andrew Feustel, Michael Good and Megan McArthur. The manifest has been adjusted to reflect current planning. The next space shuttle mission, STS-119, is targeted for launch on Feb. 12, 2009. Preparations continue for the STS-127 mission, currently targeted for launch in May 2009. That launch will be further assessed and coordinated with NASA's international partners at a later date. STS-128 is targeted for August 2009, and STS-129 is targeted for November 2009. All target launch dates are subject to change.

Notes on the program status:STS-125:  (Hubble) Hardware still has 4 to 6 weeks of schedule margin.  Mitigation plans are in place for issues that may arise during testing.  Everything looks good for the 5/12/09 launch.  In mid-March, the Program will decide whether to use single or dual pad operations for STS-125 / 400.  Ares 1-X believes they are still capable of making the 7/11/09 launch date.  They have a number of critical deliveries scheduled for late February / early March.  The status of these deliveries will be used to determine whether they can meet the 7/11/09 launch date and also will support the single -vs- dual pad resolution.STS-127: CR S042013HT is out for review to move the launch to 6/13/09.  This CR will also move STS-130 to 2/4/10.  The CR is scheduled to go to PRCB for approval on 2/19/09.  STS-127 is the LON for STS-119. <div class="Discussion_UserSignature"> </div>

However that extensionhas not been installed because the pad has not been released by the Shuttle program. The final use of the Shuttle for pad B is the rescue mission for STS-125 (Hubble rescue).  If the Program decides to use Pad A for the Hubble launch and the rescue mission the extension will be installed on pad B.The three large towers going up are away from Pad B and are not a constraint to Shuttle ops from pad B.If Ares 1X slips to the fall the 3 tower config will be ready to support Ares 1X and Ares 1 and the FSS tower extension will not be used.   "I never really thought about how they work, I just thought that they worked simply by being the tallest thing sticking up, but I guess there is more to it than that. " You are essentially correct. However there is much more to the system than the tower or towers. There is instrumentation to measure the lighting strike intensity as well as cables to increase the effectivity of the tower or towers. BTW: when are you moving your airplane to DunnAirpark? <div class="Discussion_UserSignature"> </div>
