No pics of the ice glaciers on Mars yet...?”
It's interesting that you raise this point, lozza73. Certainly some of the high mountains in the southern hemisphere surrounding the impact basins of Hellas and Agyre look like they have been subject to glacial actions like the mountains of the Lake District or mountains and fjords of Norway although they are currently bare of glaciers.
The interesting thing is the mechanism that produces such a spectacular display. I suspect that gravitational tidal forces are responsible for these effects similar to the situations of Io and Europa in the Jovian system.
The question is now whether Enceladus also has a liquid ocean under that icy crust and it appears that the answer might be a "Yes".

According to Dr Chris Smith of the Naked Scientists the geyser has a diameter of 1km!

Ohh. Now that you mention this, would this be them here. They have been in the sky at the nights for the past while in the almost exact same part of south west part area of sky. Though one of them has been there longer than the other. Its been bugging me for the past while wondering what they were
These vast glaciers hidden glaciers mean that there is a significant reservoir of water ice on Mars. Now that knowledge might be useful, not only to study the evolution of the land forms on Mars but also for any future human explorers or perhaps even colonists.

Yes but I think that the moon hides Venus while it is still light.
