LIVE coverage and updates on Atlantis launch countdown (final leg of S0007) launch attempt 1.
This is interactive, but needs to be kept on updates. Use the other threads for items such as viewing the launch, weather and general woo hooing cheerleading posts. The site will get
very busy as we get closer to launch, so please appreciate the thread needs to run on updates, not random posts.
Pre-launch article:
http://www.nasaspaceflight.com/2009/05/live-sts-125-launch-updates/(Article based on latest processing info from L2 (main one due in about 6am Eastern and followed up during the day via live MMT level coverage - such as we'll live tanking updates via console. However, items of interest etc will be summarize into this thread and the pre-launch article.) The article itself is also based on the power systems such as APUs, Fuel Cells and the SSMEs flying with Atlantis, via MMT L-1 (day) documentation, rather than writing up another mission outline for the 54th time. We'll also outline the GUCP get-wells (from 119) again, although this should not be a problem for 125.
Previous STS-125 articles:
http://www.nasaspaceflight.com/tag/sts-125/ (and there's more articles, pre-site change, which you can find by searching STS-125
http://www.nasaspaceflight.com/?s=STS-125). Easily over 100 articles.
Should Atlantis launch, this thread will continue for Flight Day 1 updates. With new threads for each of the upcoming Flight Days.
Godspeed Atlantis, go fix that telescope.

Just to get those timezones and the launch time correct: the launch is at 14:01 EDT - that is 18:01 GMT (without daylight savings), or 20:01 Central European Time (with daylight savings).
Right?

Oh, and how long is the launch window for this launch, as it is (the last in the shuttle program) due-east launch and not an ISS mission?

62 minute launch window, targeting 20 minutes in due to MPS performance reasons.

All ok so far with tanking and the ECO sensors. Atlantis behaving very well on the milestones. Only concern noted is TAL weather.

Interesting...they've pushed up the volume on the pad audio on NASA TV.
Edit: and then it was gone...probably just testing for later.
Edit 2: it's back, just mixed at lower volume.
