Sounds like they are WAY ahead of the timeline.

[MikeMi.]

Around 30-40 ahead of schedule.

Couple minutes from switching to internal power and begining of EVA-17.

Sounds like they are WAY ahead of the timeline.

Yeah, they're getting good at this.  Rob Navias is PAO again; says the goal is to get Loop A going again towards the end of the week.  (If I heard him correctly.)

I'm in travel limbo for now; can't post as much today.

[MikeMi.]

The hatch is open.

Official start of EVA-17 is 6:20 am EST (10:20 am GMT).

I'll be getting a short article on in 10 minutes - which I'll beef up by updating with key events - then I'll able to cover. Probably just in time for helmetcam
