This is Scientific American’s 60-Second Science. I’m Steve Mirsky. This will just take a minute.

 Computer status report. After its ongoing1 Mars’ missions, NASA will concentrate less on the red planet, and more on the solar system's other planets and moons, including our own. That’s what NASA administrator2 Mike Griffin told an audience of researchers last week at the 39th Lunar and Planetary Conference in Texas. The Mars Science Laboratory lands in 2010. Griffin said that NASA is now planning in earnest for an outer planets flagship mission to Europa, Titan or Ganymede. Europa and Ganymede are moons of Jupiter, Titan is the moon of Saturn3.The reorientation of NASA’s planetary exploration programs is in response to a recent National Research Council report card. The NRC gave NASA an A for its Mars work, but only a C for its overall research and analysis program and a dismal4 D for outer planets efforts. Griffin also noted5 that NASA is now planning seven different small-and-medium-class missions to the moon by 2014. And the Messenger spacecraft goes into orbit around Mercury in 2011.

 

Thanks for the minute for a Scientific American’s 60-Second Science. I’m Steve Mirsky.
