Emily:
Started 30 minutes early. Ran a little big long with the EVA, so we're actually back on time.
Was hard to prejudge the battery tasks, and booked three. We managed four, so we're ahead on EVA-3 tasks. Steve worked OBSS, plucked the cable out, tied it and the boom is back in a good config.
Finished the batteries fast enough to get to the SGANT. Really great EVA, I don't think MCC could be more proud.
FD7 will be mainly transfers and then off duty. Fairly relaxed, ahead of a very busy day on FD8.

Lead Spacewalk Office Lisa Shore:
Mike Good went to the batteries when Steve was working the OBSS to get a jump start. By the time Steve had finished we were well over half way through the prep tasks and were able to pick up on a nominal timeline.
What can I say about the Battery R&Rs, they showed great teamwork, they helped each other. When one guy had nothing but battery in his face the other guy was there to guide him.
We gave them a heads up that we'd like to have had a look at the SGANT. We sent them to the airlock to get the tools and take a look at the SGANT. Mike was not nominally trained for this, but again they just worked together really well and we got the bolts torqued down.

Questions:
Mark C - any other getahead tasks to add on EVA-3
Lisa: We're back to our original plan. All EVA-3 items are in the timeline, and a couple of get-aheads. Ammonia jumper reconfig, and restowing EVA tools.
Bill H - MMT TPS inspections:
Emily: No official decision yet, challenge is we're gathering inspections with different ways, such as Garrett's EVA-1 photos. Vehicle is looking great, but it's an unusual set of data and they are taking their time. Folks still looking at if we can add FD9 tasks on this, but expect a decision tomorrow if we'll even need to do that. Possible they'll just rely on late inspections.
Bill H - What's left outstanding after 132 for EVAs.
Emily : There's not a lot of tasks left. EVA for the summer for PGF to get modded and installed on Zarya. Small tasks, such as maintainence, but nothing real urgent.

Robert P - How many people were involved on the tie wrap.
Lisa: There was a large number of people involved, such as at the KSC area. The PTU was already out at KSC, so we utilized folks out there to start looking at the hardware. Had a full team of EVA people working packages with us. One team working the outside fix on the tie wrap, another on what tools needed to be gathered.
Clare M on MRM-1. Emily: Ingress will install the duct work tomorrow, some clamps for a good physical mate, and at the end of the mission will be removing the racks (this was all answered yesterday).
Trasfers are "a lot of bags of cats and dogs" for six people.
Marcia D on the wire tie.
Emily: The tie wasn't the cause of the problem. Once we moved the cable out the ties weren't in the locations they were designed to be in, but wasn't the cause. Lisa making the same point. Looking at photos back at the Cape to work out when the cable was in that config and work out how they got that way.
Mark K - On protective garmets for MRM-1.
Emily: In case there were bits of FOD, we take standard protection. Even something as small as a screw or tape to prevent it getting inhaled or in your eyes.
How long to get SGANT ready to be a spare.
Emily: Cables will be installed in the next few weeks, so it's a cold back up as it doesn't have connectivity to fail over from one system to the next. If primary KU failed, we'd plub in different cables. Power to the unit that is confirmed. Couple of steps to check the gimbals. Full fuctional check in the summer after installing the cables.
C&C failure:
Emily: The cap was the issue. Haven't seen the details of which bus it was. If C&C loses several busses it knows that bus has a problem. If it loses multiple busses it thinks it has a problem, which is what we think happened causing it to fail.

From ISS Daily Report for 19/05/2010:
STS-132/ULF-4’s EVA-2 was completed successfully by EV-2 Stephen Bowen & EV-3 Michael Good in 7 hours 9 minutes, accomplishing all objectives plus two get-aheads.
During EVA-2, Bowen & Good:
. Cleared the snagged cable on the PTU sensor of the OBSS, restoring it to full pan/tilt
range.
. Prepared the P6 Truss worksite for replacing the batteries (breaking
bolt torque & installing gap spanner).
. Removed & replaced four P6 batteries with new batteries from the
ICC-VLD stowing the old batteries on the ICC-VLD (the battery #4
R&R, originally planned for EVA-3, was a get-ahead).
. Performed successful troubleshooting on the SGANT as another
get-ahead, first verifying by wiggling the boom that boom & dish are
solidly fixed without relative motion at the interface, then removing
the tether installed during EVA-1 and releasing the gimbal locks that
allow the dish to rotate.
Battery R&R:
Bowen & Good replaced four of the six batteries on the B side of the P6 Truss (each of the two wings of the four solar arrays at the space station are designated either A or B), the six batteries on the A side of the P6 having been replaced in July 2009 on STS-127 (2J/A). The first old battery was moved to temporary storage on the P6 IEA (Integrated Equipment Assembly), attached to a MUT (Multi Use Tether) called a ball-stack. The remaining three batteries were then swapped out, with the old units taking the slots of the new ones on the ICC-VLD hovering nearby on the SSRMS. Finally, the first battery was transferred from the ball-stack to the remaining free slot on the ICC-VLD which was then maneuvered to SARJ clearance position.
While Tracy & Ken provided campout & prebreathe support, MS-1 Garrett Reisman & MS-4 Piers Sellers supported the spacewalkers by operating the SRMS and SSRMS. [SSRMS first assisted during the PTU cable snag clearing, then grappled the ICC-VLD at the POA on the MT MBS and maneuvered it to the P6 Truss battery R&R worksite viewed by the SRMS video cameras.]
With the new MRM-1 now attached to the FGB Nadir port, Kotov & Skvortsov spent ~1 hour on a review of ingress procedures and MRM-1 cargo transfers, supported by ground specialist tagup via S-band as required. [RSC-Energia expressed gratitude for NASA’s support, reported full access to MRM-1 telemetry and stated that the module is in good shape.]
Afterwards, Oleg & Alexander laid out the equipment and personal protection gear for their first MRM-1 ingress. A preliminary initial ingress is scheduled tomorrow for the purpose of activating air scrubbers to clean the cabin atmosphere. The hatch will then be left “ajar”, and the final full ingress will be performed after STS-132 departure.

Its just amazing how routine, simple, and easy it seems when these Astronauts do their spacewalks.. so much as changed since Ed made that first walk on Gemini 4.
Astronauts now get 6, 7 hours at a time without so much as a elevated heart rate.. where as Astronauts in the 60s had barley 20 minutes per EVA and a lot of them had heat exhaustion. I think that's due now to the amazing teamwork and training teams at NASA that they have now.. hoping it continues even into the gap and whatever comes next.

Ok, let's plan out these busy few days coming up.
FD7 - large amount of off duty, along with MRM-1's opening ingress task. Will likely write up a large status report on Atlantis' performance via MER, especially as we're close to a DAT decision on the TPS.
May 20: H-IIA - Akatsuki - Venus Climate Orbiter (PLANET-C) NET following weather scrub:
http://forum.nasaspaceflight.com/index.php?topic=18950.0 - LIVE
May 21: FD8 EVA-3 for STS-132.
Also there's the realigned launch date for the Ariane 5 ECA launch with Astra 3B and COMSATBw 2 satellites in the evening:
http://forum.nasaspaceflight.com/index.php?topic=20359.0 - LIVE
May 21/22 : Night launch of Delta IV - GPS 2F-1 - May 21:
http://forum.nasaspaceflight.com/index.php?topic=20962.0 - LIVE
Followed by STS-132 FD9 almost immediately after.
And there's major manifest evaluations going on with Shuttle, which I'm working on right now, so there's an article on that at some point, potentially within 24 hours.
Now is this what space flight's about, isn't it!
