Sometime last week, while you were at work, or at home, or at school, a little robot built here on Earth shone its lights onto a tiny patch of rocks on a planet about 200 million miles away, and — click — it took a picture, and sent that picture back home.
Using the camera at the end of its long robotic arm, Curiosity has taken a picture of a rock illuminated by the rover’s ultraviolet LEDs.
