View Full Version : Martian probes should investigate viking.

Ok, in 1976, the viking landers landed, scooped martian soil into warm liquid nutrient tanks and looked for life signs with the primitive instruments of the day.

The results were inconclusive.


Ok, I'd like to see a modern probe go to the viking landers, drill into the tanks and take samples of the contents, even if they are freeze dried by now, and example them with better instruments.

If there are microbes in the martian sands, they might have activated in the viking nutrient tanks and could have left some visible signs of life.

Maybe, maybe not. This might be great for the first manned mission, if we ever get one.

OR we could just take samples of the soil and run them through an analysis similar to that conducted by the Viking landers. Why on Earth would you want to spend the money, time and effort to develop and implement equipment that would have to disassemble the lab in order to get to the same dirt that sits underneath the lander?

Well, the argument the OP makes is


If there are microbes in the martian sands, they might have activated in the viking nutrient tanks and could have left some visible signs of life.

But I think that, unless you could do this in a manned mission, it's easier to develop good experiments on new soil samples.
