ST. LOUIS(KMOV.com) - NASA Astronaut Peggy Whitson is now the oldest woman in space.
The 56-year-old rocketed off the planet from Kazahstan at 2:20 p.m. Thursday.
Whitson will celebrate her 57th birthday on the International Space Station.
This will be her third mission to the ISS for Whitson and her second stint at Commander.
However, her record as the oldest woman in space pales in comparison to the men's record. John Glenn flew on the Space Shuttle at age 77.
