Interesting article from the beeb:
Glad to say the craft has returned some great images and some great scientific results.
Between this rover and its predecessors the past presence of water on Mars is pretty much certain.
Curiosity will search for evidence of organic materials but given Mars's harsh climate such material is not that likely to be preserved.
I wish Curiosity a long and successful mission on Mars, but my curiosity wonders what's next after Curiosity? Will there be a need to send more rovers to Mars?
