Iowa-born Peggy Whitson made history on Thursday, becoming the oldest woman to enter space after taking off from the Baikonur Cosmodrome in Kazakhstan.

NASA's Whitson, 56, along with Oleg Novitskiy of Roscosmos and Thomas Pesquet of the European Space Agency, are scheduled to dock with the International Space Station's Rassvet module on Saturday. There, they will team up with NASA's Shane Kimbrough and cosmonauts Sergey Ryzhikov and Andrey Borisenko.
