Curiosity Found Plenty Of Evidence Of Water And An Unusual Rock On Mars.

The one year spent by NASA's Mars rover Curiosity on the Red Planet has been a boon to science. Most recently, Curiosity discovered more evidence of water on the planet, as well as a mugearite, a volcanic rock totally different from other rocks previously found on Mars.

The latest round of research was collected in a special edition of the journal Science. The biggest finding was evidence of water in soil samples collected by Curiosity. According to researchers, between 1.5 and 3 percent of the soil found on Mars contains water. On its way to Mount Sharp, Curiosity discovered traces of sandstone deposited by flowing water in ancient times.

Researchers at the Los Alamos National Laboratory analyzed soil samples using several of Curiosity’s instruments. Analysis of these soil samples revealed two “components” on the surface of the planet, a fine-grained dust and coarser particles. According to the researchers, these coarser particles are possibly the residue of rocks that eroded over time.
