Since the Government can screw up a free lunch,
Id say that if we had let Burt Rutan run
the Mercury project for fame and profit we would
now have bases and bars on both the Moon and Mars.
SpaceShipOne, not a gumdrop-shaped projectile
but an airplane, zoomed into space (114 kilometers
above California) on 29 September 2004 and again
on 4 October 2004 to win the $10 million Ansari
X Prize.
Burt says, The complexity you remove can
never fail. His wind tunnel was a Ford pickup
truck with whatever was being tested mounted on
top. His pressurization system was two bottles
of compressed air and one of oxygen. His rocket
fuel was really exotic: rubber tires and laughing
gas. His flight control system was a stick, a
rudder and, above Mach 1, electric trim control
available on 747s. The spaceship was launched
at 47,000 feet from a specially designed mother
ship, the White Knight. The only computers on
board were in the navigation system and in the
cockpit display.
The real trick is slowing a spaceship down when
it comes screaming into the atmosphere
in this case at Mach 3. Rutan could have spent
all of Donald Trumps money on designing
tiles to survive when the re-entering ship reached
the melting point of fire brick and nearly cooked
his pilot, like NASA nearly cooked Shepard and
Glenn. Instead he played it cool and used air
brakes. The ship folds up like a letter in an
envelope, rotating its fuselage and wing bottoms
to present a wide flat surface to the wind. It
nearly stops dead in this feathered
mode.
The next trick is to put a space airplane into
orbit in deep space to launch satellites
for $10,000 instead of $10 million a piece. A
step in that direction was taken on 16 November
when a scramjet engine was tested in the X-43A.
This engine will carry a space plane to the top
of the mesosphere and send it off at 7000mph before
the rockets need to be fired in the exosphere
for maneuvering.
In 2007, Sir Richard Branson of the Royal Aeronautical
Society will offer tourists suborbital space flights
on the Rutan-built VSS Enterprise for £110,000
a thrill ride. Does this remind you of air races
and barn storming in the 20s? Well, it should.
In another 80 years because of business a la Pan
American who invented Irish Coffee, not government
a la Billy Mitchell who was exiled to Panama,
you will be able to fly from New York to Tokyo
in two hours or to the Moon and relax at the Club
Med there.
