Mission STS-121

Mission STS-121 took place from July 4 to 17, 2006. During these 13 days in space, the crew of Space Shuttle Discovery continued to test new equipment and procedures that increase the safety of space shuttles. Canada played a critical role in this mission by providing an extension to the Canadarm tipped with a Laser Camera System that allow the inspection of every inch of the spacecraft for possible signs of damage.

This flight to the International Space Station also delivered critical supplies and cargo to the complex for repair and future expansion of the outpost.
