- The tests carried out on board the Viking for metabolism, growth,
- photosynthesis were done by three seperate experiments,
- gas exchange, labeled release and pyrolytic release.
-
- Results:An unpredictably high level of oxygen was released
- when the samples were sitmulated by sunlight or water, but
- not if the sample was sterilized. One possible reason for this
- release of oxygen was that plants were present and undergoing
- photosynthesis. Another possible answer was that a purely
- inorganic chemical reaction was taking place. Neither of these
- possibilities could be proven or disproven conclusively, leaving
- open the question of life on Mars.

- The researcher in Antartica was Dr Wolf {spelling?}, he spent
- 20 years building the wolf trap. The wolf trap was a device
- which was suppose to be fitted to the Viking landers, but because
- of last minute budget cutbacks, it was left out. Basically the
- experiment involved adding some soil to some nutrient rich
- mixture and then detecing if anything would grow. because
- of the Viking kickback, he decided to try his device in Antartica,
- with success.

- Carl Sagan beleived that the wolf trap would have resolved
- the question of life on Mars {ie in the area of the other tests}
