Planetary Exploration - Towards new Worlds or New possibilities

摘要

While the planetary exploration programme, thus, far, has revealed much exciting scientific knowledge, very may questions remain unanswered. If, over the next century, Space is to provide any basis for overcoming the Malthusian "Limits to Growth", a great deal more will have to be known about the nature and availability of extra- Terrestrial resources. This paper looks at the steps required to discover the resources of the Solar System- Particularly the Moon, Mars, and asteroids. "in situ" propellant production may be a key transportation develop- Ment that will make these bodies accessible. Whether this will lead to new worlds to live on, or new ways of living, Remains to be seen.
