Malin space systems (managing the MGS spacecraft) are taking PUBLIC REQUESTS for new areas of mars to be photographed using their high res (1.5M/pixel) mars orbiter camera!!
It's previously only imaged about 3% of mars at this level of detail, and now anyone can suggest a new area to be imaged up close, provided you give a very detailed explanation as to why, and so long as it hasn't been photographed before at hi-res!
This is so cool...

If you had a chance, what would you suggest?!
(I say one of the sites of previous mars landers...)
