It's the slight problems that make humans in space absolutely vital.
Can you imagine what this mission would have been like if they had attempted the robotic repair???
The easiest approach would have been to have the robot carry up an entirely new Hubble, leave it in orbit, then grab the old Hubble and deorbit it.

Please! I need to start writing EVA-3's preview article. We've got spacewalks coming out of our ears on this mission

Opening comments:
Tony C: Successful and outstanding day. Tile inspection, vehicle cleared for entry. EVA-2 had a few hurdles. We completed all tasks, very happy with that. Crew will go to bed an hour later today, everything will move an hour to the right, nothing lost. Crew getting suits ready for tomorrow, EVA-3 still as planned. All instruments passed aliveness test today. Very good day

Tomas: RSUs and battery R&R were tasks today. RSUs had some hurdles. Second did not go as smoothly. Bolts were misaligned, would not engage. Used a spare RSU instead. Crew did great job on battery, some get aheads completed too.

Preston: Excited we are 2 for 2 for EVAs. Hit some rough spots, testament to perseverance of crew and Flight Director. Thrown schedule off a little, but can be accomodated. Gyro installation and batteries were accomplished today. Get-aheads set us up well for tomorrow. Things "rolling along", looking forward to tomorrow. Tomorrow is very demanding.

David: Two days in a row with "curve balls". Prediction: EVA-3 will go more smoothly than any other. WFC-3 worked well overnight, tests completed well. After mission, will need to wait 3 weeks until real imagery can be obtained. At this stage it is 100%. I think that after 7 years without people, Hubble has gone "wild" again. I view EVAs as 100% successful. We are a long way to extending Hubble's longevity. Thanks to folks on ground and the crew.

Questions from JSC:
Q: Does change in gyro line-up affect anything?
A: We've run models for all combinations, difference in longevity is very small. 3 out of 6 are new ones, we don't see this as significant detriment. Tremendous accomplishment.
Q: What made you decide to send the spare?
A: Carry a spare on every servicing flight. Have one that has flown on every mission, and today it got its shot. Called it the "hangar queen". Glad to see it there. It went in real easy.

Q: Which RSUs have what gyros?
A: RSU #1 has unit 1005 in it RSU#2 has 1004 RSU#3 has 1006 in it. (Nick - Didn't catch all that on the differences between them!)
Q: The refurb was from 1999, what is the difference between it and new unit?
A: Hubble is only user of this type of gyros. They are the most precise. To keep costs down, we take advantage of existing assets. When we bring them back, we disassemble, and see which components can be reused. We mix and match existing assets, that's how we come to where we are.

Q: Surprised by degree of difficulty so far? Could it be related to age of telescope?
A: Don't think aging has been a factor. In case of RSUs, they are built to very tight tolerances, can be difficult to get them installed, need to play with them a little bit. Never gonna understand fully what the problem is. Modified procedures seemed to work, maybe that was the key. In case of latches yesterday, three potential things that could have caused that. Can be tricky to get them to function right. Haven't worked on this instrument is a while, we were being extremely cautious with elevated torque and such.
Tomas: Talking about the fact that "easy" things have been hard and vice-versa. WFC was the "easier" task. Thought RSU problems would be somewhere else. Hope that ACS will have no issues.

Q: EVA-3 the most difficult? Comment.
A: Task designed for 2 EVAs compressed to 1 EVA. Task is challenging, due to location of repair, struts in the way. Grunsfeld has trained to do this. Grunsfeld has task "nailed". Talking about challenges faced in 2002 for one of Grunsfeld's EVAs that ran into problems but turned out smooth. Expecting tomorrow to go smooth, task is in their "genes".
