NASA launched the Mars Science Laboratory from Cape Canaveral, Fla., on Saturday. The MSL is five times heavier than the rovers currently on Mars and has twice as many scientific instruments. It will take nine months for the spacecraft to reach the Red Planet, and there's plenty of things for it to do before then.
You may not have realized it, but a piece of U.S. property was recently driving around on the surface of Mars. Tens of millions of miles away from the debt crisis, the heat wave and other big events of the summer, NASA's rover Opportunity just completed a 13-mile trip to allow scientists to examine a Martian crater.
