Kepler 22b Rocket

  1. Dec 10, 2013 #1
    People are saying that Kepler 22b looks like it may harbour life. How could we ever know? I was just wandering, but what would the delta v be to do a Hoffmann transfer (if this works on an interstellar scale) to Kepler 22b?

    Kepler 22b was the first planet in it's parent star's habitable zone that was discovered by the Kepler mission. That does not mean that it harbors life. We can get a better idea if it does harbor by looking for chemical signatures of life in its atmosphere. The technology to do that is a ways off, but it does not require going there. Going there is not feasible and won't be for a long, long time. With current technology it would take tens of millions of years to get there. Looking for chemical signatures of life is perhaps a decade or two in the future, perhaps even sooner.

    As D H indictated, it would take current spacecraft millions of years to get there (~600-620 ly).
