Mars 2020: Final three candidate sites selected

Scientists Shortlist Three Landing Sites for Mars 2020

Quote:

Participants in a landing site workshop for NASA’s upcoming Mars 2020 mission have recommended three locations on the Red Planet for further evaluation. The three potential landing sites for NASA’s next Mars rover include Northeast Syrtis (a very ancient portion of Mars’ surface), Jezero crater, (once home to an ancient Martian lake), and Columbia Hills (potentially home to an ancient hot spring, explored by NASA’s Spirit rover).

For pure field science, Jezero Crater is probably the best bet. They will get a large and well defined (fossil) river basin and delta, lacustrine environment and a good scattering of outcroppings to help sort out the context.
