Ancient lakes in Gale crater

Our latest work on the existence of an ancient lake in Gale crater has just been published in Science.

Grotzinger et al. (2015) Deposition, exhumation, and paleoclimate of an ancient lake deposit, Gale crater, Mars. Science. 350, aac7575 (2015). DOI: 10.1126/science.aac7575
