Curiosity-- NASA Mars landing Monday

[Jimbone]

The pursuit of knowledge is never unjustified.And you can't possibly know what benefits will begained from this. Consider: Orville and Wilbur Wright's first manned flight lasted a couple minutes, was the result of years of experimenting, and was about a hundred years ago. You think either of them thought their work would lead us to Mars? Because essentially that's exactly what has happened.

All flight is intertwined, so I'd probably give Robert Goddard credit for space exploration... he was the father of rocketry.

He was truly a visionary when it came to rockets.
