Skydiver Leaps From 18 Miles Up In 'Space Jump' Practice
wooferhound writes "A daredevil leapt from a balloon more than 18 miles above the Earth today, moving one step closer to a so-called 'space jump' that would set the record for the world's highest skydive. Austrian adventurer Felix Baumgartner stepped out of his custom-built capsule at an altitude of 96,640 feet (29,456 meters) above southeastern New Mexico, officials with Red Bull Stratos — the name of Baumgartner's mission — announced today. In today's jump, Baumgartner experienced freefall for three minutes and 48 seconds, reaching a top speed of 536 mph (863 kph), project officials said. Baumgartner then opened his parachute and glided to Earth safely about 10 minutes and 30 seconds after stepping into the void."
That's one small step for a man, One giant leap for me.
Well, the faster you fall, the soundier your speed becomes. The goal is to make a proper *kaboom* instead of the ordinary *swiiish*.

Upon landing Mr. Baumgartner simply requested a cigar and fresh undies.
If you have very little air resistance, you're not going to be generating any heat (you get hot from the friction caused by the air resistance).
Asteroids, satellites, and space shuttles don't just fall out of the sky, they were already moving fast enough to stay in orbit. Their massive speed helps make them hot. The jumper will not be traveling at orbital speeds, thus the increasing air resistance will be enough to slow him down before the speed+air friction gets high enough to burn him.
Kittinger's story is amazing. He used to call into a florida talk show I listened to when I lived there from time to time to talk about some of the stuff involved with his jump. He is consulting on this attempt, so while this attempt might seem a stunt, at least Kittinger is apparently getting paid for it.

3. I understand objects falling from that altitude tend to encounter very little air resistance, which means they pick up a lot of speed. The kind of speed that causes brilliant fireballs to appear in place of anything falling from that height, like asteroids, satellites, and space shuttles.
Not really. Most things that cause brilliant fireballs have a very high initial velocity (and kinetic energy) which must be dissipated when they first reach the atmosphere. This skydiver started with a vertical velocity of zero.
And since the density gradient of the atmosphere is low, a skydiver's air resistance will build up slowly bleeding off this energy gradually.
All that must be done is to bleed off the skydiver's potential energy. For a 115kg (person + gear. I'm pulling figures out of my *ss here) at 29,500m altitude, this is aprox. 32,700 Joules. Dissipated in 630 seconds, this is an average rate of 51 Watts. Warm, but not out of line with being wrapped in an electric blanket.
That same individual hitting the atmosphere at 7750 m/sec (Shuttle re-entry velocity) would have kinetic energy of 3.45E9 Joules. Over 630 seconds this would be 5.5 megawatts, although the 630 second figure does not represent the re-entry time anymore. That time would be less, giving a higher average dissipation rate. And nothing but a few ashes reaching the ground.
Have gnu, will travel.
Committees from both the Darwin Awards and Guinness will be on hand for the final jump. The Guinness people are hoping for multiple awards at the jump. Highest jump, longest free fall, highest velocity in free fall, longest scream in free fall, highest speed a human ever impacted the ground and greatest distance human remains were spread after impact.
Did he also attain distinction of being fastest non-propelled human?
No, I'm pretty sure that record was set by the Apollo 10 re-entry, at close to 40,000 km/h (almost 25,000 mph).
He's not even the fastest skydiver - that record has held for 52 years now - Joseph Kittinger did a free fall in 1960 that lasted 21% longer and reached a top speed 15% faster than what Baumgartner just did.
Actually, you don't get hot from the friction; you get hot from compressing the air in front of you.

The "Moon": A Ridiculous Liberal Myth
It amazes me that so many allegedly "educated" people have fallen so quickly and so hard for a fraudulent fabrication of such laughable proportions. The very idea that a gigantic ball of rock happens to orbit our planet, showing itself in neat, four-week cycles -- with the same side facing us all the time -- is ludicrous. Furthermore, it is an insult to common sense and a damnable affront to intellectual honesty and integrity. That people actually believe it is evidence that the liberals have wrested the last vestiges of control of our public school system from decent, God-fearing Americans (as if any further evidence was needed! Daddy's Roommate? God Almighty!)
Documentaries such as Enemy of the State have accurately portrayed the elaborate, byzantine network of surveillance satellites that the liberals have sent into space to spy on law-abiding Americans. Equipped with technology developed by Handgun Control, Inc., these satellites have the ability to detect firearms from hundreds of kilometers up. That's right, neighbors .. the next time you're out in the backyard exercising your Second Amendment rights, the liberals will see it! These satellites are sensitive enough to tell the difference between a Colt .45 and a .38 Special! And when they detect you with a firearm, their computers cross-reference the address to figure out your name, and then an enormous database housed at Berkeley is updated with information about you.
Of course, this all works fine during the day, but what about at night? Even the liberals can't control the rotation of the Earth to prevent nightfall from setting in (only Joshua was able to ask for that particular favor!) That's where the "moon" comes in. Powered by nuclear reactors, the "moon" is nothing more than an enormous balloon, emitting trillions of candlepower of gun-revealing light. Piloted by key members of the liberal community, the "moon" is strategically moved across the country, pointing out those who dare to make use of their God-given rights at night!
Yes, I know this probably sounds paranoid and preposterous, but consider this. Despite what the revisionist historians tell you, there is no mention of the "moon" anywhere in literature or historical documents -- anywhere -- before 1950. That is when it was initially launched. When President Josef Kennedy, at the State of the Union address, proclaimed "We choose to go to the moon", he may as well have said "We choose to go to the weather balloon." The subsequent faking of a "moon" landing on national TV was the first step in a long history of the erosion of our constitutional rights by leftists in this country. No longer can we hide from our government when the sun goes down.
If you could run this as a business operation, I wonder how much you could charge people for "space jumps"?
I am a licensed skydiver, and I can tell you that the way "normal" jumps are priced is there is a boarding fee generally $10-13 USD and then you pay $1 per thousand feet of altitude. This is whether you get out at 3,000 feet or 13,000 feet. But this is out of an aircraft without needing supplemental oxygen or equipment.
Specialized jumps cost more:
Hot air balloon jumps are usually around $45 and you get out anywhere between 4-6k feet.
Anything above 15,000 feet requires supplemental oxygen, so these jumps can be more expensive.
A civilian HALO jump from 30,000 feet costs around $375.
However none of that applies in this case because of all the specialized equipment for the stratos mission.
For example, the bottom of the capsule is one-use-only. Upon landing, the capsule's bottom absorbs the force of impact and "crumples", so every flight requires a replacement. There is a pressure suit which needs to fit the jumper. There is a custom parachute rig made by Velocity.
Also, the time to altitude takes a very long time, and the winds need to be just right. So it is not uncommon for them to wait days or weeks to have a window to try. They also have a large ground team. So this whole production would need to spin up for each "jumper" meaning at best you could do one or two jumpers every few weeks, at worst, one every month or two.
Not to mention each jumper would need to have a base line skydiving skill set that exceeds what most sport jumpers possess. Figure you would need to have several thousands normal skydives, including HALO jumps, before you could even begin to train for a stratos jump. Training for stratos jump would include many jumps wearing the space suit and custom velocity rig, which is not a standard rig so it has different deployment and emergency procedures. This training would need to include wind tunnel time to work on falling in a stable belly to earth orientation. It would also need to include jumps from an aircraft.
As a business operation you would likely need to charge hundreds of thousands of dollars per jumper, if not millions, and only allow "customers" who meet the qualifications.
So really, you'd have to invest several years in skydiving and have a scrooge mcduck money pond waiting for you at the end of it.
OR, you use the red bull money from all the idiots who drink red bull and you have an awesome adventure on their dime ;)
