A Possible Biogenic Origin for Hydrogen Peroxide on Mars: The Viking Results Reinterpreted

The adaptability of extremophiles on Earth raises the question of what strategies putative life might have used to adapt to the present conditions on Mars. Here, we hypothesize that organisms might utilize a water-hydrogen peroxide (H2O-H2O2) mixture rather than water as an intracellular liquid. This adaptation would have the particular advantages in the Martian environment of providing a low f...

Detection of Metabolically Produced Labeled Gas: The Viking Mars Lander

A qualitative, nonspecific method will test for life on Mars in 1976 by supplying radioactive substrates to samples of the planetary surface material. If microorganisms are present, they may assimilate one or more of the simple labeled compounds and produce radioactive gas. The compounds have been selected on the basis of biological theory and terrestrial results. The measurement of radioactive...

Convective Vortices on Mars: a Reanalysis of Viking Lander

Introduction: On 7 August 1976 the Viking 2 lander touched down at Utopia Planitia, Mars. Both Viking lander’s primary aim was to look for the presence of organic life on the surface of Mars. The lander also had a comprehensive meteorological package to monitor the martian conditions. The meteorological package included pressure, temperature, and wind sensors, enabling the landers to perform th...
