Curiosity, I guess, is something without which the human race would have been dead long back. Barely past the jubiliation of Cassinni's Saturn orbit insertion on June 30, 2004 and while still celebrating today the successful launch of Messenger's mission to Mercury, we stand awaiting yet another countdown - of New Horizons' mission to Pluto and the Kuiper Belt slated for January, 2006. Hail mankind!
