Astronauts ferried to the International Space Station by the Discovery space shuttle are hard at work this week to get its latest addition online: the $1 billion Kibo science lab module. The Kibo module, named for the Japanese word meaning "hope," will be the station's largest room at 37 feet in length — about the size of a bus's interior. Supplies for Kibo were already delivered to the station in March, and something resembling a porch will be shipped up to it next year, where astronauts will be able to conduct "outdoor" experiments.
Another important item went up with the Kibo: an inspection boom to check the Discovery spacecraft for any signs of damage during liftoff. The shuttle tore off 1,500 square feet of the flame trench during liftoff — the most damage to the launchpad in 27 years — and a few pieces of foam insulation for the Discovery's external fuel tank were also spotted falling away. The boom, equipped with a scanning laser, will allow the astronauts and mission crew here on Earth to determine whether or not the Discovery is in good enough shape to reenter the atmosphere.
