Planetary habitability: lessons learned from terrestrial analogues

Autor: Lewis Dartnell, L. J. Preston

Publikováno v: International Journal of Astrobiology. 13:81-98

Terrestrial analogue studies underpin almost all planetary missions and their use is essential in the exploration of our Solar system and in assessing the habitability of other worlds. Their value relies on the similarity of the analogue to its targe
