There are new reports of Marsquakes and even more rumbling noises picked up by the lander.
There is also a wad of material about Methane on Mars, link later
It is my submission that Mars is inhabited by the Martian Bovine. Only this theory can account for the rumbling and the methane.
If you read the Wikipedia entry on Mars Methane you will also observe that the methane mysteriously disappears. This may be much like our trees absorb CO2 here. I put this down to a herd of Martian Anticows in the atmosphere. How these exactly work is unknown to me, however I am sure there is a Youtube about it already. Then again they may be in another dimension.
