Rutan's SpaceshipOne Hits 200,000 Feet 292
An anonymous reader writes "Burt Rutan's privately-built SpaceshipOne is one step closer to winning the X-Prize after zooming to what witnesses say was somewhere around 200,000 feet on only its third powered flight. (See also the partial update from Scaled Composites.)"

No... meters. Most places in Europe use a decimal point as the thousands separator -- so $10,000.00 here becomes $10.000,00 in Europe. But even if you ignore this fact, the original poster is still correct. After all, 200.000 feet (200 feet to six significant digits) is equal to 60.960 meters (60 meters, 96.0 centimeters).
Of course, in North American-speak, he meant that 200,000 feet is 60,960 meters.

By the time the X-15 was doing its stuff, NASA was already gearing up for the Apollo program, and the ballistic missile guys (primarily lead by Von Braun, but it did involve others) were trying to push a competing program. It should be obvious who won that debate.
The Space Shuttle should have (and in a small part did) been a technological decendant of the X-15 project, but instead most of its design technologies came from the Saturn V program and its predecessors.
The promise of the X-15 was to have routine reusable aircraft for travel into space. The pilots of the X-15 were finally granted astronaut wings, but politcally even that wasn't really appreciated by the guys at NASA. The prep crew for the X-15 was just a dozen or so people, compared to the hundreds it took even for Alan Shepard to do his sub-orbital flight. It is indeed too bad that this research wasn't followed, but not because it was a technological dead-end. It wasn't followed simply because Congress in their infinite wisdom decided that programs of this nature should be cut. And it was almost impossible to get a follow-on project to go this route.
Space Ship One really is the heir apparent now of the X-15 flights, and you had better believe that Burt Rutan knows just about all there is to know about the X-15 flights... probabally a world-class expert on the subject.
Other X-class projects have been done since the X-15 (Notably the X-33) and they have all suffered with political problems coming from folks at NASA thinking they (the X-projects) are mussling into their turf. The X-prize was even named that in honor of these X-class planes and the potential they could have had if they hadn't been abandoned.
The inspiring thing is that this ship goes higher and higher, pushing the materials and seeking refinements on what they already have.
Finally, remember the saying of Robert A. Heinlein: "Low-earth orbit is half-way to the rest of the entire solar system."
That sums up the importance of these flights. If refinements of materials and general ship design gradually lead to something that goes into orbit or even can leave the earth's gravity (like the Apollo missions), the age of manned planetary exploration will truly begin. Eventually, if you keep getting higher and higher, you are going to run out of altitude to the point that it really doesn't matter any more. You will be in orbit regardless.

That's why space vehicles curve backwards as they accelerate through the atmosphere so they have plenty of angular velocity once they reach the proper altitude. Maintaining orbit is all about getting to the proper angular speed tangental to the earth.
Orbitting the earth is much more difficult than touching space on a ballistic trajectory. You need way more engine power and heat ablative materials and design to handle the re-entry friction.

So kinetic energy K = m/2 GM/r
Potential energy, though, is defined as the integral from an infinite distance to the current radius:
U = GMm/r
Oddly enough, this means that the kinetic energy is always half the potential energy for a circular orbit (2K = U)
Also, note that if your kinetic energy equals or exceeds your potential, then you're at or above escape velocity and aren't in orbit any more (Vescape^2 = GM/r).
