NASA's Mars Robot Set to Begin Drilling (Picture)
The robot rover, Curiosity, is currently making its way across the Gale Crater on Mars. Images were recently released of the robot's tire tracks. They were taken from the Mars Reconnaissance Orbiter (MRO), which has been orbiting the planet since 2006.
The rover, which is the size of a small car, is currently travelling across the red planet toward Yellowknife Bay where it will begin drilling for samples. According to scientists, the location contains sedimentary rocks that could provide further evidence of a past abundance of water in the Gale Crater. Whether or not the rover will find evidence of life, though, is another question entirely. In addition to drilling, the rover is meant to give scientists a better picture of Mars and hopefully add to their understanding of the planet's geological history.
While Curiosity works on the ground, though, MRO works from space. The images captured by the orbiter have changed the way scientists view Mars. It has helped keep close tabs on the surface of the planet and the missions that NASA sends there.
