Felix Baumgartner intends to ride a balloon to space, and jump off with a parachute. After being put on hold in 2010, the Red Bull Stratos mission has set a launch window for July of this year. The mission will send Baumgartner 120,000 feet above the Earth’s surface in a pressurized capsule that’s lifted by a helium balloon.

Baumgartner, in a flight suit designed to prevent his blood from literally boiling from the difference in air pressure at that altitude, will then fall back to Earth. Assuming he lands safely (which is safe to assume given the meticulous planning involved), the fall will set a world record for highest and longest recorded skydive.

Within the first 30 seconds of freefall, he is projected to become the first human to break the speed of sound without the assistance of an engine.

For once, “don’t try this at home” doesn’t even apply.
