S120-E-006875 (26 Oct. 2007) --- Astronaut Scott Parazynski, STS-120 mission specialist, is pictured in the shuttle's cargo bay during the first of five scheduled sessions of extravehicular activity to perform work on the International Space Station while it is visited by the Space Shuttle Discovery. Node 2, also known as Harmony, joined the growing station complex, thanks to the work of the two spacewalkers in conjunction with that of their crewmates who remained in the shirt sleeve environment of the two spacecraft.
