With the debris strike on Atlantis’ starboard chine Thermal Protection System (TPS) - now confirmed as a liberation from an Ice Frost Ramp on External Tank (ET-130) – cleared within hours of its observation via the Orbiter Boom Sensor System (OBSS), the orbiter and her STS-125 crew have completed rendezvous operations with the Hubble Space Telescope [...]

Another major milestone in the flow towards the final Hubble Servicing Mission has taken place, after Atlantis completed mating operations with External Tank (ET-130) inside the Vehicle Assembly Building (VAB). However, an incident during mating has resulted in tile damage on the belly of the orbiter, which was repaired on Friday morning.

Atlantis’ trip to service the Hubble Space Telescope remains on track for May, although another key milestone meeting is due in early January to discuss the status of the replacement Hubble hardware – which is still undergoing testing. An alternative launch date in November remains an option.

The complicated task of remotely switching the Hubble Space Telescope (HST) over to its Science Data Formatter (SDF) “Side B” of the Science Instrument Command and Data Handler (SIC&DH) has been completed with only a few minor issues – issues which became worse on Friday.
HST engineers started transmitting lines of complex programming to the aging [...]
STS-125 has been given a new “work-to” launch date of February 17, pending a November 5 meeting that will likely result in a Change Request (CR) to officially re-align the near-term launch manifest.
Hubble troubleshooting is proceeding well, with NASA engineers preparing to switch over from the Side A control system, to the back-up Side B.
Those preparations [...]
Preliminary milestone schedules have been created for the complex dual processing flows of Atlantis and Endeavour – which will hopefully result in the latter launching in just under six weeks time.
While plans are now solidifying for the short term, evaluations are continuing on whether Atlantis will need to be de-stacked over the New Year.
As previously [...]
As NASA and the SSP (Space Shuttle Program) refine their orbiter schedules, preparations for STS-125’s rollback to the Vehicle Assembly Building (VAB) are proceeding – with confirmation that payload removal operations will begin this weekend.
October 20 has been pencilled in for Atlantis’ rollback from Pad 39A, which will clear the pad for hosting Endeavour.
Processing at [...]
While the status of STS-125’s Hubble Servicing Mission remains fluid, managers at the Kennedy Space Center (KSC) are creating plans to move Endeavour and her stack to Pad 39A in around two weeks time.
This plan would result in Endeavour launching as STS-126 for the final mission of the year, around November 14.
Hubble Fallout – STS-126 Gaining [...]
A major failure of the “Side A” control system on the Hubble Space Telescope has delayed STS-125’s launch as far as 2009.
The failure has shut down Hubble’s science operations, and is currently unable to send data back to Earth. Attempts will be made to switch to the “Side B” control system later this week.
