Well, 2 year extension and $15 million is a good start
The extended 2 year mission will aide in possible landing sites for the future mars landers along with futher mapping.
MGS and the MOC is breaking the record books with 25,000 orbits, over 170,000 photos which is more than all other Mars missions combined and MGS holds the longest running Mars mission to date.
All that and only 5% of Mars have been mapped. Narrow camera woes.
