Upon arrival, Space Shuttle commander Pamela Melroy will be greeted by Space Station commander Peggy Whitson in a Space first, the first meeting of two female commanders.
"It will be the first time in the 50-year history of spaceflight that two women are in charge of two spacecraft at the same time," Yahoo New reported.
This was not a NASA planned photo op, but a coincidence as Whitson took over the outpost on Oct. 12 and Melroy's mission was originally scheduled to have been completed a while ago.
