Well, not only that, but things like upper atmospheric changes (along with solar wind/energy variances) that affect drag, and even miniscule transient gravitational irregularities, will affect the ISS orbit and times all the way up until the terminal launch countdown (and after that they calculate that into their orbital change/approach vectors).

It's details like these that keep me in awe of the entire system and the fact that it's ever worked. It reminds me of how endlessly complicated spaceflight is. Thanks for the info Mike! -

When is rollout scheduled to be seen on NASA TV for the 16th?

Currently not listed. And I'm not even sure if NASA TV plans to cover it. It all depends on when exactly rollout starts on the 16th. And remember, the 16th is just an NET date. It could slip.

NASA Holds Media Teleconference on Upcoming Shuttle Mission
NASA will hold a media teleconference Friday, May 11, no earlier than 3 p.m. EDT to discuss the space shuttle Atlantis' external fuel tank. The tank has been repaired after a hail storm struck Kennedy Space Center, Fla. The teleconference follows a meeting to schedule the shuttle's return to the launch pad for the upcoming mission, STS-117.
The briefing participants are:
-- Bill Gerstenmaier, associate administrator, Space Operations Mission
Directorate
-- Wayne Hale, manager, Space Shuttle Program
-- John Chapman, manager, External Tank Project
-- Mike Leinbach, NASA launch director
So that's after the rollout review of the same day. -

Rounded up the info on L2 today:
http://www.nasaspaceflight.com/content/?cid=5095
The likihood this will be a new looking ET-124 comes from MAF sources who claim it won't rollout with the repaired areas showing. We'll see, but the final sprays certainly suggest this is possible too. -

Chris, you've got a "ripped" where I think you meant "rippled".
Good article. So the Dalmatian loses it's spots! -

Thanks, you're right - sorted.
We'll probably have to wait and see the webcam images over the coming days, but I do get the impression you'll not see patches and spots all over the tank when she's at the pad. -

Will Clayton Anderson have the chance to board Atlantis on the pad for a dress rehearsal like his fellow crewmates did before the hailstorm?
-

May 16 now documented as rollout date. The 11th review could change this, but the current state of play is the 16th.
And NET for launch is still June 8.

He will get catch up training, but nothing like a full on TCDT.

I see that subtropical storm Andrea is brewing. It doesn't sound like it will be a problem for rollout ("THE OFFICIAL FORECAST SHOWS DISSIPATION NEAR THE COAST IN LESS THAN FIVE DAYS. HOWEVER...SINCE ANDREA MIGHT BRING WINDS OF TROPICAL STORM FORCE TO THE COAST...A TROPICAL STORM WATCH HAS BEEN ISSUED.")
Any of the resident weather experts (Rob?) have anything to add to that? -

Interesting to hear (from the article) that they're going to spray the top of the tank to make it look brand new. My guess would be to give a good coating to the repaired areas and further mitigate debris risks but I could be mistaken. Can anyone elaborate on why they're performing that work? And great news about the SRB segments on the train. That's definitely a relief.

There's an ongoing evaluation today on news late last night that the repairs have hit a problem.
"Lockheed Martin is currently evaluating some areas of lowfoam in the closeout."

I'm no cook, but: Imagine you're icing a cake. You smooth over the icing, but find it's not level and there's dips. The dips are low foam. -

Thanks Chris!! You could also compare it to a city crew fixing a pothole in the street with pavement. After it's been driven over a couple times it is not level with the rest of the street anymore. The pothole is back and they might as well not even filled it in.
