Astronaut training in parabolic flight - Astronauts training in zero G - NASA astronaut candidates train in weightlessness aboard a NASA KC-135 aircraft with astronauts from the Japanese Space Agency (JAXA). October 2004. A number of NASA's 2004 class of astronaut candidates and some JAXA astronauts tumble during one of a series of reduced gravity sessions provided by special parabolas flown by a KC - 135 aircraft over the Gulf of Mexico. Randolph J. (Randy) Bresnik, pilot candidate, and Shannon Walker, mission specialist candidate, are in the foreground. This activity is part of the early training program for candidates, who came aboard the NASA program in spring of this year. October 2004
