STS-102 Extravehicular Activities

The STS-102 crew conducted two space walks at the International Space Station. The purpose of the space walks was to prepare the Leonardo Multi-Purpose Logistics Module, or MPLM, for transfer to the station, to install hardware needed for Assembly Flight 6A, and to deliver spare parts to the International Space Station.
