Is it possible for there to be life of anaerobic bacteria in the
ice caps of the planet Mars?
As far as I know, there is no evidence against such life on Mars,
so the short answer is: yes.
Sure -- except that it would be pretty limited in its lifestyle -
- no cable TV for this bug. Because the temperatures on Mars can reach to
below -100 C at the poles, life would be extremely difficult, and the lack of
nutrients anywhere except from inorganic chemical constituents in the soil or
in the ice around the bacterial colonies would keep the menu fairly short.
Oh, and do not rule out aerobes -- Mars has an atmosphere, though admittedly
not much of one, and there are such organisms as microaerophiles and also
microorganisms known as facultative anaerobes, which can grow in the presence
of oxygen but which do not need it to survive.
