A well done to NASA for a successful landing for the rover Curiosity. No matter how you feel about nerdish accomplishments, this is actual rocket science.
When I first heard about the "seven minutes of terror" landing plan, I thought they'd gotten too gadgety and were going to have complete failure. A landing which involves a heat shield, self-guided landing thrusters, a sonic parachute, rockets and a crane sounds way too complicated. But it all worked perfectly.
We watched the Discovery special about the rover and the landing. Of particular interest was the ChemCam which shoots a high powered laser at rocks to vaporize them and then analyse the dust.
As I watched, the following occured to me: We have built a robot with a death ray and sent it to another planet. We have officially become the bad aliens in 1950s science fiction.
