Saturday Night Science: The Case for Space

“The Case for Space” by Robert ZubrinFifty years ago, with the successful landing of Apollo 11 on the Moon, it appeared that the road to the expansion of human activity from its cradle on Earth into the immensely larger arena of the solar system was open. The infrastructure built for Project Apollo, including that in the original 1963 development plan for the Merritt Island area could support Saturn V launches every two weeks. Equipped with nuclear-powered upper stages (under active development by Project NERVA, and accommodated in plans for a Nuclear Assembly Building near the Vehicle Assembly Building), the launchers and support facilities were more than adequate to support construction of a large space station in Earth orbit, a permanently-occupied base on the Moon, exploration of near-Earth asteroids, and manned landings on Mars in the 1980s.

But this was not to be. Those envisioning this optimistic future fundamentally misunderstood the motivation for Project Apollo. It was not about, and never was about, opening the space frontier. Instead, it was a battle for prestige in the Cold War and, once won (indeed, well before the Moon landing), the budget necessary to support such an extravagant program (which threw away skyscraper-sized rockets with every launch), began to evaporate. NASA was ready to do the Buck Rogers stuff, but Washington wasn’t about to come up with the bucks to pay for it. In 1965 and 1966, the NASA budget peaked at over 4% of all federal government spending. By calendar year 1969, when Apollo 11 landed on the Moon, it had already fallen to 2.31% of the federal budget, and with relatively small year to year variations, has settled at around one half of one percent of the federal budget in recent years. Apart from a small band of space enthusiasts, there is no public clamour for increasing NASA’s budget (which is consistently over-estimated by the public as a much larger fraction of federal spending than it actually receives), and there is no prospect for a political consensus emerging to fund an increase....

Jeff Bezos Gets It

Space colony: O'Neill CylinderEver since I read Gerard K. O’Neill’s The High Frontier (link is to my review when I re-read the book in 2013) in the 1970s, it has been obvious to me that the medium-term human destiny is to expand from using resources on the surface of Earth to exploit the abundant resources of the solar system, where more than 99% of the matter and energy are available for the taking and the constraints of a closed ecosystem do not exist.  There were technological barriers to overcome in order to get from here to there, but none of them required technologies we didn’t already understand or investments greater than were regularly squandered on futile wars or counterproductive social programmes.

I thought, “All it would take is a wealthy individual who gets it and is willing to stake their personal fortune on a human destiny which is optimistic and open-ended, as opposed to the claustrophobic vision of the slavers who see future generations confined on one planet, increasingly under the control of masters who worship at the altar of ‘sustainability’ ”.  The amount of money required to bootstrap this future would be in the round-off of the government budget of a medium-sized industrialised country, but you don’t get vision from coercive government—just control and keeping everybody in their place....
