Document Summary
Article title: fossilized remains of underground cracks suggest water flowed beneath martian surface . Source: brown university, astronomy magazine, january 31st, 2013. In prior research, narrow ridges found within impact craters on mars have been noted. Although they have been noticed, their actual source of being and how they were formed was unknown. Using nasa"s mars reconnaissance orbiter, researchers from brown university, The research was led by lee saper (a recent graduate) and jack mustard (professor of geological studies). Their hypothesis before actually setting out to test it was that the ridges may have started out as faults and fractures which formed due to impact events having rattled the planet"s crust. They also believed that if there had been water in the subsurface, it would have circulated through the cracks and slowly filled them with mineral deposits, making them harder than the surrounding rocks.
