This Aug. 2, 2012 file photo shows Nick Lam, data controller, monitoring the Mars rover Curiosity from the Deep Space Network's control room at NASA's Jet Propulsion Laboratory in Pasadena, Calif. NASA's Curiosity rover is zooming toward Mars. With about a day to go until a landing attempt, the space agency says the nuclear-powered rover appears on course. Tension will be high late Sunday, Aug. 5, 2012, when it plummets during the "seven minutes of terror." Skimming the top of the Martian atmosphere at 13,000 mph, the rover needs to brake to a stop — in seven minutes — and set its six wheels down on the surface.
