Because it's Monday and because it's awesome, below are the highlights from the Felix Baumgartner's 24-mile plunge to Earth from the edge of space. Yes, he survived! Humans are amazing.
The 128k refers to the altitude that Baumgartner was at when he leaped from his capsule: 128,000 feet. That altitude relates to 39,000 meters, or 24.24 miles (39.01 kilometers). This is really high above the Earth.
In fact, the officially recognized edge of outer space --that which gives a person crossing this boundary the designation "astronaut" -- is 62 miles (100 kilometers) above the Earth's sea level.
So, Baumgartner was about 40% the distance to outer space, and we was only wearing a highly advanced pressure suit and helmet during his leap from the edge of space.
Also known as the Kármán line, this is the boundary between Earth's atmosphere and outer space, as recognized by the international standard setting and record-keeping body for aeronautics and astronautics, the Fédération Aéronautique Internationale (FAI).
