I was watching a talk on CD-Rom last night by Dr. Gerald K. O’Neill, one of the leading advocates of space colonisation. Way back in the 1970s, O’Neill suggested that humanity should colonise space by constructing special space habitats at the Lagrange points between the Moon and Earth. The L5 points are excellent sites for space colonies, as they’re the points at which the gravity from the Moon and Earth interact to form stable points. The space habitats he designed were solar powered cities, with areas of parkland, housing and manufacturing areas. The CD-Rom with these talks came with a book I bought nearly a decade ago by him, The High Frontier: Human Colonies in Space (Burlington Ontario: Apogee Books 2000). However, for one reason or another I hadn’t got round to watching it. I think part of the problem may have been that the computer I may have been using at the time had an incompatible version of Windows.
Along with his other arguments about the ecological and economic benefits space colonisation would bring, and the technological and scientific methods, which would be used in the construction of these colonies, Dr. O’Neill also mentioned that, according to the Russian rocket pioneer, Konstantin Tsiolkovskii, it would be this New Year, 2017, when humanity would first break out from Earth and land on the Moon. O’Neill makes the point that instead, we got to the Moon 50 years early. He then goes on to predict that, despite cuts to NASA’s budget and the low priority given to funding science, and particularly to supporting the space programme for itself rather than those products which have spun off it, humanity will be colonising space in a centuries’ time. He even predicts that by that time, we may well be starting to send space colonies outside the solar system to colonise the neighbouring stars.
The video seems to date from around 1982, and I’m rather more pessimistic about humanity’s possible colonisation of space. There’s immense public interest in it, but it is expensive using the technology currently available. The costs aren’t prohibitively so. I went to a symposium at the British Interplanetary Society nearly a decade and a half ago, where one of the speakers pointed out that the cost of constructing an orbital hotel actually are the same as building a tower block here on Earth. And once the commercial exploitation of space begins in earnest, launch costs can be expected to fall as new ways and launch vehicles are developed to put people and objects into space more easily and cheaply. Indeed, one of the aerospace engineers talking at the Symposium also made the point that there were planes and vehicles planned in the 1940s and ’50s which would have had the ability to achieve orbit. So, far from humanity being 50 years ahead of schedule, by another set of standards we’re 60 or so years behind.
Still, I hope that with China now planning to send a probe to the far side of the Moon and its unstated intention eventually to send humans there, 2017 won’t be too far off Tsiolkovskii’s prediction. I’d like humanity to begin colonising the Moon as well as the Red Planet. At the moment, we’re just languishing, sending people to the International Space Station. It’s a great scientific achievement, but there’s so much more that needs to be done to open up the High Frontier properly.
