The Martian Chronicles: New Discoveries on the Red Planet, by Burkhard Bilger

One could argue that the technological triumphs embodied in our robotic explorations of Mars far exceed those that put men on the moon.  Missing, however, is the drama of putting human life at risk, and the ease with which our imagination can put us in the shoes of the explorer.

The analogy is far from perfect, but it emphasizes some critically important aspects of the processes of science.
