Zap! Curiosity shoots soil on Mars with laser
October 24, 2012
This bizarre-looking animation is not some kind zit popping (which is the first thing that came to mind when I first saw it), but in fact the hole left behind in some Martian soil after the Curiosity rover zapped with a high-powered laser in order to study its chemical composition. Curiosity has been steadily traveling across its home, Gale Crater, and doing lots of good science along the way. This latest experiment zapped the soil 30 times to heat it up to a temperature so hot that it glows. Each element glows at a specific color of light when heated to those temperatures, and an instrument called a spectroscope reads those colors emitted and can discern exactly what elements the glowing material is made of. Curiosity also recently took several scoops of soil from the surface which will be delivered to various onboard instruments this week, which will directly examine its mineral makeup. I’m looking forward the release of those results, as they could tell us whether or not Mars could’ve supported life in the past. But I couldn’t resist posting this bizarre animated GIF… just keep staring at that for a while.
