Crew Activity Report for STS-100 Flight Day 4, April 22, 2001. This video describes activities performed during the first space walk of STS-100 performed by Mission Specialists Chris Hadfield and Scott Parazynski. The day's activity began with Pilot Jeff Ashby using Endeavour's robotic arm to grapple the Spacelab Pallet containing the Space Station Remote Manipulator System (SSRMS) and attaching it to a fixture located on the Destiny Laboratory module. The space walkers then began the activity of providing power and data to the Canadian-built SSRMS. The Ultra-high Frequency antenna was then installed. After this, the space walkers then worked to remove several bolts securing the SSRMS to the Spacelab Pallet. Once the space walk was completed, Expedition Two crewmembers Susan Helms and Jim Voss then performed initial tests of the newly installed robotic arm from the robotics workstation inside the Destiny module.
