L-R: Parazynski, Wheelock, Wilson, Zamka, Melroy, Tani, Nespoli
Space Shuttle Discovery (STS-120) took off October 23, 2007, being the 23rd mission to the International Space Station. Commander Pamela Melroy was the second woman after Eileen Collins to become commander of a space shuttle mission. When they docked with the ISS, Peggy Whitson was commander of the space station so for the first time, there were two female mission commanders in space.
The rest of the crew consisted of Pilot George Zamka, Mission Specialist 1 Douglas Wheelock, Mission Specialist 2 Stephanie Wilson, Mission Specialist 3, Scott Parazynski, Mission Specialist 4 Paolo Nespoli (on the ISS right now!), and Mission Specialist 5 Daniel Tani.
