Peggy Whitson - oldest woman in space

Record-breaking astronaut Peggy Whitson has blasted off into space for her third mission to the International Space Station - and hopes to break some more records while she's there. The veteran Nasa astronaut is the first woman to have commanded the ISS and already holds the record for the longest time spent in space by a woman. This time - turning 57 while on mission - she is the oldest woman in space. She blasted off from the Baikonur cosmodrome in Kazakhstan on Friday.
