Microgravity

Exterior view of Combustion Module-2 with an Experiment Module partially extracted during a crew training session. The original CM flew on the Microgravity Sciences Lab-1 and 1R in 1997. It has been refurbished and placed in new racks for flight on the STS-107 Research 1 mission in 2001. See MSFC 0100158 for a view with callouts. Glenn Research in Cleveland, OH, manages the project.
