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

fsm · Oct 22, 2008

Thanks everyone - I also didnt realise the spare had both Side A/B in one module. Nothing new on the spare, but this from the New Scientist article doesnt sound good: (http://space.newscientist.com/article/dn14908-hubble-replacement-part-has-glitches-of-its-own.html) The spare, known as the Science Instrument/Command & Data Handling (SI/C&DH) system, was developed years after Hubble's unit and is not an exact replica of it, says Hubble manager Preston Burch of Goddard. For example, Hubble's unit stores data using older, "core" memory technology, some types of which are very robust against power failures. The flight spare, however, uses modern CMOS memory, which can be lost when the unit loses power. The flight spare was tested around the time of the telescope's launch in 1990, and again in 2001, during tests of a cooling unit for the probe's Near Infrared Camera and Multi-Object Spectrometer. Records show that glitches occurred in the device during those tests, Burch told New Scientist.The team is still digging through paperwork on the unit, but the system seems to have trouble relaying commands. "There were a number of problems that were discovered with it," Burch told New Scientist. "Those anomalies were never fully resolved." The team is now re-assembling the unit and plans to power it up on a mock-up of the telescope's electrical system, called the Vehicle Electrical System Test facility, or VEST, as early as 20 October. But given the device's troubled history, the planned February launch might be "very ambitious", Burch told New Scientist. "We won't have a lot of confidence in our February schedule until we've had an opportunity to run this thing on the VEST for a week or two to see what we've got." If problems with the unit are difficult to fix, this might result in additional delays to the servicing mission. This could strain NASA's already tight shuttle launch schedule, since the agency hopes to launch the repair mission with a back-up shuttle at the ready and the shuttles are set to retire in 2010 This mission may not happen by Feb 09. Anyone know what else would happen instead? Does NASA have another mission lined up for the Shuttle it can bring forward? <div class="Discussion_UserSignature"> </div>

Posted by shuttle_guy</DIV>Do you have any feeling for at what point they might decide it's not worth it. More specifically, when does the damage to Ares outwiegh the gain to Hubble. If they can't make May, will they still hold out for a later date? I know this would all be high level decisions, but I wasn't sure if anybody had heard anything about this, or has any feelings on the matter.On a related but slightly different note: Does anybody know if the lightning tower work at 39B will continue? Can they continue to erect them beyond their current point, and still propperly support a shuttle launch at the site? Thanks <div class="Discussion_UserSignature"> </div>

The "damage" is only to delay Ares 1X which has no impact to ARES at all since Ares 1X is not a constraint to Ares 1. Ares 1X is a waste of money and time with essentially nothing to do with the development of Ares 1.The lightening mod work on pad B is still in work. it has not been stopped.

http://www.space.com/news/081023-hubble-telescope-fix-update.html  The switch to the backup channel, called Side B, was a tricky maneuver that required the activation of five other backup systems that had also been in hibernation since Hubble's launch. I love things like this. Firstly, the main communication link with the ground had a full back up. Secondly, after 19 years, the back up worked.  Here is hoping that ALL future vehicles are built with the foresight of the Hubble.

The time of Thursday's media teleconference to discuss the status of the shuttle servicing mission to the Hubble Space Telescope has changed to 5:30 p.m. EDT. A news conference at the Kennedy Space Center in Florida to discuss the status of the next space shuttle launch now will begin no earlier than 6:30 p.m.Due to the US' funky implimetation of Daylight Saving Time, they are 2130 and 2230 UT. <div class="Discussion_UserSignature"> But the Krell forgot one thing John.

Posted by shuttle_guy</DIV>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)?

Now that the switch to the "B" side of the Science Data Formatter has been completed, the first image has been released. It's my new desktop!! There are no words, but here are those that go with the image... Just a couple of days after the orbiting observatory was brought back online, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147. The image demonstrated that the camera is working exactly as it was before going offline, thereby scoring a "perfect 10" both for performance and beauty. The two galaxies happen to be oriented so that they appear to mark the number 10. The left-most galaxy, or the "one" in this image, is relatively undisturbed apart from a smooth ring of starlight. It appears nearly on edge to our line of sight. The right- most galaxy, resembling a "zero," exhibits a clumpy, blue ring of intense star formation. The blue ring was most probably formed after the galaxy on the left passed through the galaxy on the right. Just as a pebble thrown into a pond creates an outwardly moving circular wave, a propagating ring of higher density was generated at the point of impact. As this excess density collided with outer material that was moving inward due to the gravitational pull of the two galaxies, shocks and dense gas were produced, stimulating star formation. The dusty reddish knot at the lower left of the blue ring probably marks the location of the original nucleus of the galaxy that was hit. Arp 147 appears in the Arp Atlas of Peculiar Galaxies, compiled by Halton Arp in the 1960s and published in 1966. This picture was assembled from WFPC2 images taken with three separate filters. The blue, visible-light, and infrared filters are represented by the colors blue, green, and red, respectively. The galaxy pair was photographed on October 27-28, 2008. Arp 147 lies in the constellation Cetus, and it is more than 400 million light-years away from Earth.
