[SpaceProgram] Introduction & Leightweight probes

[Andreas Sturm]

Maybe we should start a new thread with that?


Great idea, but what exactly:

There's a dome of glas in which there are some organisms. Do they get their
oxygen/carbon dioxide out of a tank or shall it be a closed cycle (as much
as possible)?

How do you confirm biological activities?

With bacteria you see a lawn of them when they thrive. Optical density can
work also.

Liches grow very slow, so it's difficult to see the difference. A carbon
dioxide and oxygen sensor is expensive.


What would be interesting: Grow bacteria on nothing but moon soil. Taake
some soil, add water, atmosphere and bacteria. Will they thrive? -> If so,
phosphorus etc. is in the moon soil.



There is a fish that makes electrical discharges to paralyse other fish
(get food and defense).
If bacteria can also produce electricity, you could just measure the
voltage thus seeing how much activity there is.


or this: Bacteria that produce methane or hydrogen (better methane because
lower osmosis!). Use this as an additional fuel for the probe. E.g. fuel
cell. Or methanol producing -> methanol fuel cell. Voltage is directly
proportinal to how much bacteria are their alive.
