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

<p><BR/>Replying to:<BR/><DIV CLASS='Discussion_PostQuote'>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. <br />Posted by emerrill</DIV></p><p>The payload will be pulled out over the next few days then we need to offload the 31,000 pounds of hypergolic prop we just loaded a week ago. The off load is being done incase we end destacking the Orbiter and rolling it back to the OPF. (This is desired to prevent&nbsp;weight and balance issues during the de-mate). </p> <div class="Discussion_UserSignature"> </div>

As of now the only potential reason to de mate the Orbiter and take it to the VAB is the issue of moisture in the payload bay doors which are composit. When the doors are out in the unconditioned air in the VAB and at the pad with the Rotating&nbsp;Service Structure pulled back they absorb moisture from the atmosphere. Excessive moisture would boil out during ascent and could cause structural damage to the doors. Once they are in a air conditioned environment in the OPF or ar the pad with the RSS up against the vehicle the moisture evolves out of the doors over time.</p> <div class="Discussion_UserSignature"> </div>

Ahh, no big deal. Get some retired person from Fairchild in to troubleshoot to component level. Write up a rework plan. Procure replacement components or equivalent from the early to mid 80's. Get them installed. Run it through an Acceptance Test with no anomolies. How long could it take? I don't see it happening by May and I don't even know what's wrong.

<p>All in all, the part was designed to be replaced. It will wind up being replaced and the Hubble will go down in history as the a great refurbishable NASA program breaking all records for science and marketing and whatever other measure they have. The ISS keeps getting built, but where is the science?&nbsp; </p><p>If they had flown before this part went down, the Hubble could easily have gone completely silent before it's time. By Feb or March they will have worked through the issues, and that will be that. Good job all around. </p>

I was a little confused by an article on TFT. It noted the the 39A RSS was going to roll back today to accept the STS-126 cargo, but that isn't being delivered until the 23rd (with OV-104 rolling back the 20th). I assume there is some innacuracy in these statements, or is the RSS really going to be open for the entire week? <div class="Discussion_UserSignature"> </div>

<p>The Hubble Space Telescope team completed switching the required hardware modules to their B-sides about 9:30 a.m. this morning and received telemetry that verified they had good data. Everything at this point looks good.<br /><br />The 486 computer on Hubble was reloaded with data around noon and successfully performed a data dump back to the ground to verify all the loads were proper. At 1:10 p.m. this afternoon the team brought Hubble out of safe mode and placed the 486 computer back in control. Late this afternoon, Gyro #4 (which was needed for safe mode) will be turned off.<br /><br />The team will reconfigure Side B of the Science Instrument Command & Data Handling (SIC&DH) computer later today and verify it is functioning properly. <br /><br />Around 6 p.m. this evening the spacecraft will begin executing a pre-science command load, which involves sending normal commands to control the spacecraft and resume communications satellite tracking with the HST high gain antennas.<br /><br />&ldquo;We won&rsquo;t know if we&rsquo;ve been completely successful until around midnight Wednesday when we demonstrate that the SIC&DH Side B is talking to the instruments and able to pass data to the ground,&rdquo; said HST Operations Deputy Project Manager Keith Kalinowski at NASA&rsquo;s Goddard Space Flight Center in Greenbelt, Md. <br /></p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.

<p>During the night of Oct. 15, Space Telescope Operations Control Center engineers at NASA&rsquo;s Goddard Space Flight Center turned on and checked out Side &lsquo;B&rsquo; of Hubble&rsquo;s Science Instrument Control and Data Handling (SIC&DH) system. <br /><br />Subsequently, the Advanced Camera for Surveys (ACS), Wide Field Planetary Camera 2 (WFPC2) and Near Infrared Camera and Multi-Object Spectrometer (NICMOS) instruments were retrieved from safe mode to establish that each has a working interface to the Side B SIC&DH. The instruments were then commanded back into safe mode, and will remain in that state until the SI C&DH begins issuing commands to them later today.<br /><br />Around noon today commands to recover Hubble&rsquo;s science instruments from their safe modes will begin and internal exposures and calibrations of the telescope&rsquo;s science instruments will occur before midnight Thursday. <br /><br />Scientists at the Space Telescope Science Institute in Baltimore should complete their review of the internal exposures by noon on Friday, October 17. This procedure involves collecting and comparing baseline exposures previously supported by Side A of the SI C&DH to new exposures supported by Side B. This review will be one last check of the &ldquo;transparency&rdquo; (non-impact) of switching to the redundant spacecraft electronics the Hubble team activated on Wednesday.<br /><br />A full schedule of science observations with the WFPC2 camera, ACS&rsquo; Solar Blind Channel camera, and the Fine Guidance Sensors will resume early Friday morning. <br /></p> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
