If you missed it on your local news, you can pick up the
most recent Forbes article about the Space-X Dragon spacecraft docking at the International Space Station with
5,000 pounds of supplies last week direct from the link. It may not seem that
important at first – it is the fourth time the Dragon capsule has docked with the station, after all – but once
you consider that price and convenience are the two major factors that have limited
the commercial exploitation of space, this even becomes very significant. As
exciting as the sound and fury of a rocket launch is, the critical aspect to
any transportation system is reliability. A vehicle that can go someone once
(or even six times) is at best a curiosity, at least from a business
standpoint. A vehicle that can go somewhere whenever you want it to is a
business asset. The Dragon has made
the flight to the ISS four times already, as opposed to the single-use launch
vehicles of the last century, and there is reason to believe it could do so indefinitely
– or, at least, dozens of additional times. Assuming that you could find a
cost-effective way of launching it…
This is what makes the other part of the linked article so interesting.
The successful use of a privately-funded, privately designed launcher means
that it is now possible for private companies to launch profit-seeking enterprises
into Earth orbit without needing support from NASA or our national government.
But even more potentially important is the successful test of the reusable Falcon 9 rocket. In theory, a reusable
orbital launch vehicle would enable Space-X to lift payloads into space at a
lower cost than any other entity in history – effectively opening up the
commercial use of space to a huge range of companies that could never have
afforded to place payload on a Space Shuttle or a Russian conventional rocket.
A mass-produced reusable launcher would lower the costs still further. And if
the company can produce a version of the Dragon
– or one of their other designs – that is safe enough to be certified for human
use, they could lift people to orbit for a fraction of what the so-called “Space
Tourists” have been paying…
Now, even I have to admit that there are still a lot of “ifs”
in that description, and a corresponding number of developments that we still
have to await. It is possible that another company, or even another launch
technology (such as the winged rockets being developed for Virgin Galactic)
will become this century’s answer to Pan Am, leading the way into space and on
across the cosmos. It is also possible that none of these things will pan out,
commercial space travel will remain on hold for another century or two, or that
humans will succeed in destroying our planet’s biosphere before we can get off
of it and effectively exterminate ourselves. If I had all of the answers I’d be
a multi-billionaire financial advisor and philanthropist, not a scruffy blogger
nobody ever reads. But all of that said, I can’t help but think that what may
be the most important technological development since the wheel may be taking
place in the sky over our heads this week…
