To update from L2. Atlantis suffered some damage during the ET mate (soft mate, hard mate, umblicals now complete). She has some tile damage, but they are evaluating repairs. Confidence is high she won't need to be demated and rolled back to the OPF, which could have been likely if the hit was on the ET doors for example.
I'm writing an article on it.

"Confidence is high she won't need to be demated and rolled back to the OPF"
That's great to hear Chris - I was getting just a little concerned about that. If they would have had to roll back, would they have been able to try for May 12th anyway?

Has a Shuttle ever been damaged during the ET mating process ??

Last I saw there were only 4-days of contingency for May 12.

4 at the pad and 1 in the VAB...not as much as some other flows but still more then what's planned on STS-127: 0 in VAB, 3 at Pad B, 0 at Pad A.

The L2 reports speak of the damage being in a difficult area, but not a threat to the launch date at this time. I'd wait for Chris' article.

Just read the article. The phrase at the end regarding tracing what was originally thought to be a problem with one of the HST's SIC&DH's subsystems "turned out to be a misbehaving VAX computer. Wow. That took me back. I used a Digitial Equipment Corporation VAX as a server in my work with Geographic Information Software. . . . in 1987. I would guess that such is roughly the vintage of server technology that we're talking about here, given the age of the HST, and particularly its subsystems. I know this is a common occurrence in space hardware (orbiter uses "old" computers and software), but it still caught my eye.

Article on the tile damage, flow latest and on the replacement HST hardware etc - from L2:
Excellent article Chris.
I would like to ask what that means -
"the socket from the torque wrench was dislodged and fell"?
Have some toubles with visualisation this technical stuff (and translat it into my language). Want ask for a photo or short explanation.
Thanks

We'll see about a picture, but it appears the incident related to a wrench, which the socket was being attached to, but the socket popped out and dropped from one of the high platforms. Complete accident obviously.

I would assume that the torque wrench has a 1" or ¾" square drive with different sockets to attach depending on the size of the nut being torqued. This has happened to me when tightening nuts on my vehicles. If the socket is not pushed fully on to the square drive to the detent position (a spring loaded ball in an intentation), then when using the torque wrench at load, especially with an extension drive, the socket spins off the end of the drive. In the case of my car there is not far for it to drop. On a stacked orbiter there is time for the socket to reach substantial speed and presumably cause damage to the TPS unfortunately.

Putty repair applied overnight, now setting. Rollout will remain on schedule.

Latest NASA update on Hubble electronics:
"Goddard engineer Steve Leete performs a mechanical fit-check of a contingency tool on the replacement Science Instrument Control and Data Handling (SI C&DH) unit in Goddard’s large clean room. The SI C&DH passed it final functional test and will be transported to Kennedy Space Center on March 29. Once it arrives, it will be integrated onto the Multi-Use Logistics Equipment (MULE) Shuttle Carrier.
Goddard engineers re-install the Cosmic Origins Spectrograph instrument into its Shuttle carrier at the Payload Hazardous Systems Facility at Kennedy Space Center. The SM4 flight hardware is being prepared to re-enter the Shuttle launch flow in preparation for a May 12 launch."

Thanks for that update!
And a great thanks to those on the ground to make it in time and to make it happen! This is exciting. I was one to push this off, but now that it's ready, I'm really pumped.
