  ESA - Space Science - Darwin overview
Darwin will be a flotilla of four or five free-flying spacecraft that will search for Earth-like planets around other stars and analyse their atmospheres for the chemical signature of life.
Darwin's goals were to detect Earth-like planets circling nearby stars and to set constraints on the possibility of the existence of life as we know it on these planets.
ESA continued to investigate whether there was any way to achieve the same scientific results using just four free-flying telescopes instead of eight.

  Darwin (ESA) - Wikipedia, the free encyclopedia
Darwin is a proposed European Space Agency (ESA) mission designed to directly detect Earth-like planets orbiting nearby stars, and search for evidence of life on these planets.
The presence of oxygen in the atmosphere would be evidence for life, as oxygen is too reactive to exist without being continually replenished as a byproduct of biological photosynthesis.

Darwin, however, in a reliable way, can detect, through its mid-infrared signatures, ecosystems which have developed oxygenic photosynthesis.
The two photochemical sources of oxygen are shown to interfere with each other; when the carbon dioxide pressure is high enough to produce appreciable amounts of oxygen and ozone, it also masks the ozone feature; the by-products of water photolysis destroy ozone.
