The Space Shuttle Atlantis is scheduled for launch on Thursday at 1:31 PM Pacific Standard Time. It will be the 152nd human crewed US space flight and the 121st time a space shuttle has been launched. Besides hauling up the Columbus Module for the International Space Station, it will also be taking up a spare part for the grinding solar panel joint. The Columbus Module is 23 feet long and 15 feet in diameter. It will add 2648 cubic feet of living space to the station. It has a mass of more than 22,700 pounds.
Currently the International Space Station has more living space than an average 3 bedroom house; when it is completed in 2010, it will be larger than a 5 bedroom house.
