Mission to the Edge of Space Feature Summary

From Physics Research
Mission to the Edge of Space
The figure at the bottom of the photo is Felix Baumgartner, shortly after he jumped from an altitude of 39 kilometers (24 miles). There, the thin atmosphere produces very little air resistance, so he was almost in free fall (in free fall, the only force acting on an object is gravity). He accelerated rapidly, broke the sound barrier, and went on to about Mach 1.2 (20% above the speed of sound).
