Radar shows clues to past

This article is a review of a recent scientific paper published in Nature regarding the results of a radar study of the surface of Mars. Scientists discovered that the surface of the planet that we see may be a lot older than we thought since craters were detected sub- surface level. This study is relevant to the search for life on Mars because it allows the researches to study the processes that might have led to the hiding of the below-surface craters. It also gives insight to what the surface of the planet looked like years ago which could provide evidence for life.
