Extreme environments and exobiology

Giornale Botanico Italiano (Florence, Italy: 1962), 1993
Ecological research on extreme environments can be applied to exobiological problems such as the question of life on Mars. If life forms (fossil or extant) are found on Mars, their study will help to solve fundamental questions about the nature of life on Earth.

The maintenance of ambiguity in Martian exobiology

Social Studies of Science, 2022
How do scientists maintain their research programs in the face of not finding anything? Continual failure to produce results can result in declining support, scientific controversy and credibility challenges. We elaborate on a crucial mechanism for sustaining the credibility of research programs through periods of non-detection: the maintenance of ...
