Mars Rover Curiosity has been safely landed on Mars. By any measure this is an astonishing feat of engineering and a triumph of scientific imagination. I have had nothing to do with this personally and yet it makes me astonishingly happy. The very thought that humanity has the breadth of imagination and skill to pull off something so monumentally challenging and to use the modern parlance 'awesome' is inspiring. It is a triumph of 'scientific imagineering' (a term I hereby coin and expect to get next to no general usage for evermore!).
