Earlier in the month I did an interview with the charming Dr Seth Shostak from Radio SETI, on his programme Are We Alone. (I'm going to admit that I have a teeny tiny crush on him now). The theme of this episode was space archaeology, as described below:
Indiana Jones meets Star Trek in the field of space archaeology. Satellites scan ancient ruins so that scientists can map them without disturbing one grain of sand. Discover how some archaeologists forsake their spades and brushes in favor of examining historic sites from hundreds of miles high.
Also, if you were to hunt for alien artifacts – what would you look for? Why ET might choose to send snail mail rather than a radio signal.
Plus, the culture of the hardware we send into space, and roaming the Earth, the moon, and Mars the Google way.
