Successful Launch of Integral

An anonymous submitter writes "The INTErnational Gamma-Ray Astrophysics Laboratory has successfully launched from Baikonur at 4:41UT this morning. See ESA's launch page. Launch, upper stage, and solar panel deployment (the times when we held our breath) all went without a hitch. The most sensitive gamma-ray observatory yet is now beginning operations. See ESA's Integral pages for more about the mission."
