During test jumps, the robot briefly experienced accelerations of about 13.8 g — more than three times
those stomached by astronauts on the space shuttle as they were boosted into orbit.
The space shuttle is an ear - splitting, bone - rattling ride, beginning with eight minutes of inertial forces peaking at three g's (three times an individual
astronaut's weight) followed
by a near - instant,
stomach - churning flip to zero gravity.
