Seven minutes of terror

I'll come back to energy tomorrow, but I wanted to take a moment to congratulate the scientists and engineers at NASA on the incredible news from Mars. I'm sure if you read this blog you already picked up on this, but yesterday Curiosity landed safely on Mars. The landing used a very unique system. First a parachute helped slow down the landing vehicle, then rockets slowed down the descent stage even further, until it was left hovering about 25 feet above the surface of the planet. Then the Curiosity rover was lowered down from this 'sky crane' on cables, to touch down and roll off on its merry way. Alex Kobbs (Kooberz) made a fun video of this landing.
