The two-stage SpaceX Falcon 9 launch vehicle lifts off from Space Launch Complex 40 at Cape Canaveral Air Force Station, carrying the SpaceX Dragon resupply spacecraft to the International Space Station. Liftoff was at 5:42 a.m. EDT on Friday, June 29, 2018. On the company’s 15th Commercial Resupply Services mission to the International Space Station, Dragon is filled with supplies and payloads, including critical materials to support several science and research investigations that will occur during Expedition 56. The spacecraft’s unpressurized trunk is carrying a Canadian-built Latching End Effector, or LEE. This new LEE will replace a failed unit astronauts removed during a series of spacewalks in the fall of 2017. Each end of the Canadarm2 robotic arm has an identical LEE, and they are used as the “hands” that grapple payloads and visiting cargo spaceships.
