One super jump for man, one incredible jump for mankind
Tuesday, February 28th, 2006
Yesterday’s Wall Street Journal (link via Die Welt) had an absolutely fantastic story about the 61-year-old French daredevil Michel Fournier, who is planning to jump from 25 miles up in outer space (approximately 40 kilometers or 131,200 feet). Check out the attached graphic to see exactly how high 25 miles is - the French call it Le Grand Saut, or The Super Jump. (If you have trouble reading the graphic - the guy will break through the sound barrier in free fall, traveling faster than 700 miles per hour while he does it) Let’s just put it this way - at that jump altitude (literally, on the edge of outer space), a lot of bad things start happening to the human body:
“Belly-flopping from the edge of space isn’t just an incredibly long parachute ride. At that altitude, conditions quickly turn deadly. Above 40,000 feet, the atmosphere is so thin that unprotected people lose consciousness in around 12 seconds. Even with an air supply, nitrogen bubbles may form in the blood and soft tissue if the jumper hasn’t prepared by inhaling pure oxygen for several hours. If the jumper is unprotected above 50,000 feet or so, saliva boils off the tongue, and body parts begin swelling painfully. Lungs may hemorrhage as they and the skull fill with liquid.”
As the current record holder (a retired U.S. Air Force colonel) puts it: “Space is hostile.” With that in mind, the French daredevil/parachutist/adventurer has put together a lethal training regimen that blows away any kind of “boot camp workout” the local fitness chains put together:
“To prepare, Mr. Fournier has checked his equipment by spending hours locked in a pressure chamber at near-vacuum conditions. In another test, he donned his three-layer suit, which consists of a thermal skin that can keep him warm for 10 minutes at minus 150 degrees Fahrenheit. Over that he put on a pressure suit shielded by a windproof shell that remains pliable at low temperature. Then he stood in a wind tunnel as minus 22 degree air blasted him at 100 mph, producing an effective temperature of -238 degrees.
Mr. Fournier undergoes batteries of medical tests and avoids salt and sugar, in part because nitrogen bubbles form quickly in fat cells. He wakes daily around 5 a.m. for two hours of jogging in the ravines near his house, followed by an hour-long workout and yoga.”
