Janice Voss, former NASA astronaut and one of only six women to go into space five times, has died in Arizona, her alma mater Purdue University reported. Voss, 55, died Monday in Scottsdale where she was undergoing treatment for breast cancer, Discover News reported. Voss flew on five space shuttle missions between 1993 and 2000 and was payload commander on two of them. On her missions she totaled 49 days in orbit.
