The STS-100 mission launched for the International Space Station (ISS) on April 19, 2001 as the sixth station assembly flight. Main objectives included the delivery and installation of the Canadian-built Space Station Remote Manipulator System (SSRMS), or Canadarm2, the installation of a UHF anterna for space-to-space communications for U.S. based space walks, and the delivery of supplies via the Italian Multipurpose Logistics Module (MPLM) "Raffaello". This is an STS-110 onboard photo of Astronaut James S. Voss, Expedition Two flight engineer, peering into the pressurized Mating Adapter (PMA-2) prior hatch opening.
