Science, 1967
The article which Bond's committee objects to is an examination of the basic assumptions of the current spacecraft sterilization policy in the light of new knowledge of the planet Mars. It shows that the validity of these assumptions is, at the very least, questionable.

Organics are expected to exist on Mars based on meteorite infall, in situ production, and any possible biological sources. Yet they have not been detected on the martian surface; are they there, or are we not capable enough to detect them? The Viking gas chromatograph-mass spectrometer did not detect organics in the headspace of heated soil samples ...

Mars X: A Mars Mission Architecture with Lunar-Mars Synergy
AIP Conference Proceedings, 2006A human mission to Mars, if it is to be cost effective, should take maximum advantage of previous efforts at the Moon, in terms of habitats, heavy lift boosters, and vehicles. It must also make use of nuclear site power for bases. However, to make such an effort sustainable over many administrations, it should not make use of nuclear propulsion.

Numerous science fiction novels and movies deal with colonization of hostile planets, and generally take two approaches to the establishment of settlements: Terraforming and modification of the planet to an Earth-like state to accommodate the colonists, or enclosed colonies where the establishment of Earth-like conditions is confined to buildings and ...
