The control room erupted in cheers and hugs for over 15 minutes as the scientists, engineers and technicians got word that the latest American rover robot, Curiosity, landed on Mars.

The photo was just a thumbnail-sized black-and-white photo, but it brought a roomful of cheers. It showed the fairly flat surface and one of the rover's wheels when it arrived following a complicated landing operation that included, a heat shield, a parachute, four rocket engines and a tethered released.

There will be more throughout the day from JPL/NASA in Pasadena, California. Everything worked!
