There is now a story on SDC. To me this is just fine. The unit failed in time for it to be replaced. Unfortunate in one way, but fortunate, in that it will insure redundancy through the end of the life of HST. ( Once they get STS 125 up there )

<p>"MEDIA ADVISORY: M08-187<br /><br />NASA TO DISCUSS HUBBLE ANOMALY AND SERVICING MISSION LAUNCH DELAY<br /><br />WASHINGTON -- NASA will host a media teleconference at 6 p.m. EDT <br />today to discuss a significant Hubble Space Telescope anomaly that <br />occurred this weekend affecting the storage and transmittal of <br />science data to Earth. Fixing the problem will delay next month's <br />space shuttle Atlantis Hubble servicing mission.<br /><br />The briefing participants are: <br />- Ed Weiler, associate administrator of the Science Mission <br />Directorate at NASA Headquarters in Washington<br />- John Shannon, Shuttle Program manager at NASA's Johnson Space Center <br />in Houston<br />- Preston Burch, Hubble manager at NASA's Goddard Space Flight Center <br />in Greenbelt, Md.<br /><br />To participate in the teleconference, reporters in the U.S. should <br />call 1-800-369-6087 and use the pass code Hubble. International <br />reporters should call 1-773-756-0843.<br /><br />As a result of the launch delay, NASA has postponed the planned Oct. 3 <br />Flight Readiness Review and subsequent news conference. The review <br />will occur at a later date.<br /><br />The malfunctioning system is Hubble's Control Unit/Science Data <br />Formatter - Side A. Shortly after 8 p.m. on Saturday, Sept. 27, the <br />telescope's spacecraft computer issued commands to safe the payload <br />computer and science instruments when errors were detected within the <br />Science Data Formatter. An attempt to reset the formatter and obtain <br />a dump of the payload computer's memory was unsuccessful.<br /><br />Additional testing demonstrates Side A no longer supports the transfer <br />of science data to the ground. A transition to the redundant Side B <br />should restore full functionality to the science instruments and <br />operations.<br /><br />The transition to Side B operations is complex. It requires that five <br />other modules used in managing data also be switched to their B-side <br />systems. The B-sides of these modules last were activated during <br />ground tests in the late 1980s and/or early 1990, prior to launch.<br /><br />The Hubble operations team has begun work on the Side B transition and <br />believes it will be ready to reconfigure Hubble later this week. The <br />transition will happen after the team completes a readiness review.<br /><br />Hubble could return to science operations in the immediate future if <br />the reconfiguration is successful. Even so, the agency is <br />investigating the possibility of flying a back-up replacement system, <br />which could be installed during the servicing mission."</p><p>&nbsp;By the sounds of it, this is going to delay the launch?</p> <div class="Discussion_UserSignature"> </div>

<p>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 </p> <div class="Discussion_UserSignature"> </div>

<p>According to TFT, the mission has been delayed until 2009. Next mission will be STS-126 on Nov 16th:</p><p>&nbsp;</p><p>http://www.floridatoday.com/content/blogs/space/2008/09/nasa-delays-hubble-mission-to-2009.shtml </p> <div class="Discussion_UserSignature"> </div>

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? <div class="Discussion_UserSignature"> </div>

Assuming what has been speculated is true, then its going to be another delay to the construction of the space station. (Feb mission to the ISS will now be the Hubble mission). Starting to wonder how much contingency they have in the program left to finish the ISS <div class="Discussion_UserSignature"> </div>

It was already supposed to go up on Nov 16th. The only way it will have no impact (that I see) on the remaining manifest is if they can get it up early enough in Jan 2009 to not effect STS-119, which is targeted for Feb 12th it looks like. So they would have to launch in the first two weeks or so of Jan 09 for there be the least impact, if I'm putting this all together correctly. </p> <div class="Discussion_UserSignature"> </div>

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.</p><p>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.</p> <div class="Discussion_UserSignature"> </div>
