以上是JPL模拟动画。今天Rover车自带8磅核燃料开始了它到火星去的孤单旅行。

 

“NASA's latest mission, the Mars Science Laboratory (MSL), launched Saturday morning. It's another six-wheeled rover, but much larger than the rovers Spirit and Opportunity that landed on Mars in 2004. They weighed under 400 pounds. MSL weighs nearly a ton and is about the size of a small compact car.

Another important difference between MSL and its predecessors is it doesn't rely on solar panels for its power. Instead, it's carrying 8 pounds of plutonium that gives off heat that is converted to electricity.”
