Immunological detection of small organic molecules in the presence of perchlorates: relevance to the life marker chip and life detection on Mars. [PDF]

, 2011
The proposed ExoMars mission, due to launch in 2018, aims to look for evidence of extant and extinct life in martian rocks and regolith. Previous attempts to detect organic molecules of biological or abiotic origin on Mars have been unsuccessful ...

Analytical Chemistry in Exobiology

Biological Sciences in Space, 1988
Recent and scheduled chemical analysis in space missions are reviewed. Recent progress in analytical chemistry have made it possible to analyze chemical cpmposition of extraterrestrial samples in space. VEGA-1 and Giotto utilized mass spectrometers to analyze cometary dust particles. Phobos I and II are flying toward Mars and its moons.

Exobiology and the search for biological signatures on Mars [PDF]

, 1988
In preparation for a Mars Rover/Sample return mission, the mission goals and objectives must be identified. One of the most important objectives must address exobiology and the question of the possibility of the origin and evolution of life on Mars.

Exobiology site priorities for Mars Pathfinder [PDF]

, 1994
The fact that life developed on the Earth within the first billion years of its history makes it quite plausible that life may have also developed on Mars. If life did develop on Mars, it undoubtedly left behind a fossil record.
