While anchored to a foot restraint on the end of the Orbiter Boom Sensor System, astronaut Scott Parazynski assesses his repair work as the solar array is fully deployed during the STS-120 mission's fourth spacewalk on Nov. 3, 2007. During the spacewalk, Parazynski cut a snagged wire and installed improvised stabilizers for the solar array.
While anchored to a foot restraint on the end of the Orbiter Boom Sensor System, astronaut Scott Parazynski assesses his repair work as the solar array is fully deployed during the STS-120 mission’s fourth spacewalk on Nov. 3, 2007 while Space Shuttle Discovery is docked with the International Space Station. During the 7-hour, 19-minute spacewalk, Parazynski cut a snagged wire and installed improvised stabilizers designed to strengthen the damaged solar array’s structure and stability in the vicinity of the damage.Image Credit: NASA
