The reason for Kepler-22b's fame is that it might sustain living organisms. But what if it does? I suspect that if life were discovered the first thing we'd want to do after we'd recovered from the initial awe would be to exploit it.
The last few years have been heady for planet hunters. First the hot Jupiters; then the will-o'-the-wisp Glieslings and their cousins; and the results from the Kepler mission, one of which is Kepler-22b.
