SpaceShipOne re-entry - Flight 13P



Speaking of Re-entry ain't the front of the craft a bit unprrotected
in that department?

Reentry isn't really that big a deal for an X-prize contender.
depending on the flight profile used, Maximum Mach Number would be in
teh region of Mach 5. Not an everysay occurance, but also a much mre
pleasant environment than, say, a reentry from orbit.

Think X-15 (Which was flying the same profile in 1963) rather than
Space Shuttle. There's a big difference between the two.

This is not a slap at Rutan or Scaled Composites - They're doing a
damned good job, running an extremenly professional program, and
theu're my favorites for the X-Prize - or whatever the new name is,
nad it'll be a real landmark. But it's not going to be performing
anything at all like a system that will be going into orbit, or doing
anything other than carrying a couple of people to 100 Km & back.

The jump from X-Prize to Space Travel is like the Ortieg Prize
(Lindberg) to the Pan Am Clippers. (And the relationship of the
X-Prize to the Orteig Prize is not a coincidence) The one-time
expedition (It was too involved to call it a stunt) was do-able in
1927. The useful stuff didn't happen until 1939.

Agreed. A shuttle is coming in at Mach 25+ from a much higher altitude.
It basically free falls, using gravity as it's engine, not to mention its
base speed of Mach 25+ before it even starts to "fall" back towards Earth.
The frictional forces at those speeds compared to the speed that
SpaceShipOne will be flying is night and day. No comparison.
