Slight satellite switching issue at the start of coverage (accidentally started running the recording of yesterday's ISS update), but straightened out.

Kelly Humphries is the PAO for the opening of coverage.

At the outset of the broadcast, Kelly Humphries said that they were about 25 minutes down on the timeline, due to earlier issues with EV-2's comm cap.

As noted earlier, the 40-minute prebreathe clock will end in a few moments (ground said they'd actually started it at the end of EMU purge) and the go for depress steps should occur shortly.
