Paul asks…
there is a lot of artificial objects on Mars and dont they harm the planet?
i dont mean that mars is a tiny planey but still those thigs will be alien to the martian environment. and god knows some of them may still be moving around. nobody knows where they are most of them as there connections were lost before they ceased there works

I wonder sometimes if we are unintentionally sending bacteria, to Mars, and if we have not already sent it to the moon. What is this bacteria going to do, say in a million years?
