Here's why: (from my blog http://alspolitics.blogspot.com/2010/02/obamas-brilliant-space-policy.htmlhttp://alspolitics.blogspot.com/2010/02/obamas-brilliant-space-policy.html)
Prologue: I want to build space settlements. I want Life to grow
outward from this beautiful but tiny planet and fill the solar system.
This is technically feasible but incredibly difficult (for engineers,
that's the fun part).
Yesterday's space program was all about putting a very small number of
people on the Moon entirely at enormous government expense. It wasn't
doing much for space settlement. For space settlement, we need to put
huge numbers of people in space mostly at their own expense. The key
is much, much better transportation from Earth to space because today
it costs thousands of dollars per pound and the failure rate is a
percent or two. Yet another expensive government owned transportation
system, as we were developing, can't deliver. We need better
technology, a private sector human-rated launch industry so people can
buy a ticket with their own money, and, above all, much higher launch
volume. Today, the whole world launches less than 100 times per year.
At that rate we'll never settle space.
In Paths to Space Settlement I identified three near term projects
that would develop most of the technology and infrastructure necessary
to settle the solar system: space tourism, space solar power, and
planetary defense. President Obama's new space policy takes a big step
for all three.
Much of President Obama's new space policy, about $2 billion/year, is
to develop better Earth to orbit transportation and, especially,
develop private sector companies to take people into orbit. After a
year of ramping up, the budget provides $1.4 billion per year to help
private firms develop human-rated launchers and successful companies
will have a core tenant flying government astronauts to the
International Space Station (ISS). But the real payoff isn't flying to
the ISS, it's space tourism. In “Researching the Space Tourism
Market,” Crouch estimates that at $100,000/flight about 400,000 people
will want to go a year. Even with a 100 person vehicle, and the
largest today carries 10, that would pay for 4,000 launches a year.
There are many surveys supporting traffic at similar levels and higher
if the price comes down. Furthermore, Bigelow Aerospace has launched
two small space hotel prototypes and plans to launch a full sized
system in a couple of years, but there will be no customers without a
private sector vehicle to bring them there. President Obama's new
space policy may be just the ticket.
The other big potential market for launch is space solar power (SSP)
-- gathering solar energy in huge satellites with wireless power
transmission to Earth. For SSP to supply 1/3 of today's energy needs
would require approximately 125,000 launches of a heavy lift vehicle
capable of taking 500 tons to orbit (the largest vehicle today can
lift perhaps 40 tons). President Obama's budget allocates almost $600
million/year to develop heavy lift launch technology. SSP development
is not part of the new program, the policy's biggest deficiency, but
vehicle development won't start for a few years giving SSP advocates
time to make the case for SSP-related requirements.
President Obama's policy also quintuples NASA's planetary defense
budget, from $4 million to $20 million. This will not only help find
asteroids in time to deflect them before hitting Earth, but locate
most of the larger near-earth asteroids which will tell us where the
materials we need for space settlement are. For example, one of the
key problems in orbital settlement development is access to sufficient
materials as millions of tons of radiation shielding and structure are
needed. Building an orbital settlement co-located with an asteroid
solves this problem very nicely.
The new budget also ramps up to $3 billion/year to develop and
demonstrate new space technology, including fuel depots, life support,
and space resource utilization, which will help when the time comes to
build space settlements.
President Obama's policy does a lot of other sensible things. For
example, the old policy, after spending something like $100 billion to
develop the ISS, planned to destroy it five years after completion and
had very few plans to actually use it. The new policy extends the
ISS's life and provides funds to actually use the ISS for America's
benefit. The new policy also increases Earth observation funding
substantially so we can understand what is happening to Earth and
perhaps avoid creating serous problems.
President Obama's space policy abandons "Apollo on Steroids," the
third attempt to recreate the glory of the brilliant 1960s era program
by going back to the Moon and on to Mars. Apollo was great. It ended
35 years ago. Get over it. We don't need "Apollo on Steroids," we need
a program that benefits the people of Earth and lets millions of us go
to space on their own dime. I doubt that Obama read Paths to Space
Settlement before creating his space policy, but he might as well
have. Brilliant!

If we had gotten serious about space solar power (SSP) in the 1970s
it's quite likely that we would not be in the global warming and
energy pickle we find ourselves in today. Let's make sure we're not
saying the same thing in 2040.

In a late 2004 talk, Rutan made the following predictions:
1) Within 5 years 3,000 tourists will have been to space -- this did not happen.
2) Within 15 years sub-orbital tourism will be affordable, and 50,000 people will have flown.
3) Within 15 years the first, expensive orbital tourist flights will have happened.
4) Within 25 years orbital tourism will be affordable.
There have been a lot of wild claims in this business, but Rutan may know what he's talking about. His privately financed SpaceShip One was piloted into space three times in 2004, and Rutan has a contract with Virgin Galactic to build a true sub-orbital tourist vehicle.

I agree. The two key technologies I'd like to see addressed explicitly are:
1) the Levy-French plasma radiation shield.
2) an all Lunar Resources rocket burning LOX and Aluminum.
I like many others agree with the cancellation. You can find my reasons
