Optical Activity for Exobiology and the Exploration of Mars
The crucial role of a sterically specified informational macromolecule argues for optical activity as an assay for the presence of biogeny on a planet. Recent developments in the measurement of optical activity and their relevance to exobiology are discussed.

Exobiology and the Exploration of Mars
Our limited understanding of the Martian environment has stimulated much speculation on the possible existence of a. Martin biota. This understanding is being steadily improved by ground-based observing techniques. Rapid advances have been made by the Mariner IV flyby and will be made by the Mariner 1969 flybys and the Mariner 1971 orbiters.

The outer solar system: Perspectives for exobiology
The outer solar system contains many environments of interest for studies of the origin of life. Recent observations support the idea that Jupiter and Saturn have retained the mixture of elements originally present in the solar nebula. Subsequent low temperature chemistry has produced the expected array of simple molecules giving characteristic ...
