Ken Ganga, a member of the Planck satellite collaboration, has some nice pictures of the launch on his blog. (Not exactly breaking news, but I just found out about these pictures.) There’s also a story about a potentially fatal problem with the satellite that was caught just barely before launch.
By the way, in addition to his Planck blog, Ken has a personal blog, mostly about funny things he’s found while living as an American expatriate in Paris.
