I think we were too optimistic about space in 1969 and we
are too pessimistic about space now.
On Dec. 17, 1903, the Wright Brothers made their historic
first flight. Less than 24 years later, the world celebrated the triumph
of Lindbergh crossing the Atlantic. A mere 20 years after that,
Chuck Yeager broke the sound barrier. And 22 years after that,
Neil Armstrong first walked on the moon.
was launched into orbit.
In the 70 years from the Wright Brothers through SkyLab there was rapid,
continuous, and amazing progress in aerospace.
People saw this great progress and expected it to continue.
In the 30 years from SkyLab till now,
there has really been very little progress.
Space Shuttle was supposed to be amazing in lowering the
cost of getting into space. In practice, it is actually more expensive
per pound and so fails to deliver as advertised.
The Saturn V of the 1960's was cheaper and
probably more reliable.
Both the Saturn V and the Shuttle take off with about 7.5 million pounds
of thrust, but the Saturn V delivered 120 tons of payload to orbit while
the Shuttle gets about 20 tons there. So while the Shuttle is
partly reusable (or rebuildable), it does not work out cheaper.
Given that there has been so little progress in the last 30 years,
even space enthusiasts are expecting rather slow space development
going forward from 2003.
I think that the next two decades will have amazing advances,
probably more impressive to people living through them than
the advances of the 50's and 60's were to those people.
The reason the coming years are going to be so impressive
is that private enterprise will be able to justify
space development for things like
space tethers, space tourism, and
Space won't be mostly a government thing any more.
So it will be very competitive, cost effective, and advance rapidly.
Historians of 2023 will look back
and say the average person was too pessimistic about the
future of space in 2003.
