Go Atlantis! (Updated)

Today marks the first launch attempt for STS-122 aboard the shuttle Atlantis. Launch is scheduled for 2:45 PM Eastern Time today. Weather is currently the only factor that the launch team is concerned with, as previously pesky sensors have been behaving themselves today. You can follow the mission over at nasaspaceflight.com. Thanks to Chris Bergin and the team there for the image of the orbiter at the pad in this post.

Godspeed, Atlantis!

Update: 3:30 PM EST - Atlantis is safely on orbit in what may be the cleanest launch since the program returned to flight.
