Catching up with private space ventures

This excellent entry from Alan Boyle's always-worthwhile Cosmic Log catches up with news from the rocketplane entrepreneurs and Bigelow Aerospace, which apparently has a new deal with Rocketplane Kistler for support of its orbital hotel concept. There is also new information on the SpaceX Falcon 1 test earlier this month. It's now clear the first stage bumped into the back of the second after separation, although it's less certain whether that had an effect on the second stage guidance problem that halted the flight well short of orbit.
