Felix Baumgartner, in pressurized suit on platform at left, prepares to enter the balloon capsule in Roswell, N.M. on Tuesday, Oct. 9, 2012. Baumgartner will attempt to break the speed of sound with his own body by jumping from the space capsule lifted by a 30 million cubic foot helium balloon. Baumgartner plans to jump from an altitude of 120,000 feet - an altitude chosen to enable him to achieve Mach 1 in freefall - which will deliver scientific data to the aerospace community about human survival from high altitudes.
