just want to say congratulations to Curiosity's successful landing on Mars. Well done!
This was an accomplishment to boast. We know more about the surface of the moon than about the bottom of the ocean, and we know more about Mars than about the moon.
IMHO, we need to do a bit more study of this planet than we do other planets. If we do not really understand what goes on here, how can we understand what goes on there?
