NASA Curiosity rover investigates mysterious shiny Mars boulder
NASA's Curiosity rover is a science laboratory on wheels, but its team back on Earth relies on its "eyes" to point out unusual items of interest on Mars. The rover just spotted a conspicuous boulder in the distance that's worth a closer look.
The Curiosity team described the boulder as large, dark and shiny. Planetary geologist Melissa Rice from Western Washington University noted it "does not look like any other rocks in the surrounding landscape" in a rover mission update on Monday.
