<human>: Can you provide a brief overview of the text?

Kepler was recently discovered to probably be in the habitable zone and likely has land and water. For purposes of this, assume we know for sure it is habitable.

It's a [generation ship] with a self sustaining biosphere. Let's assume an [antimatter drive] capable of moving at 0.8c. Kepler is 600 lightyears away, so this trip will take 750 years. Assuming an average lifespan of 70 years, this will take 11-12 generations. You will die on the ship and only your distant relatives will make it.

I personally would be glad to do it. I don't think there's anything more important than getting humanity out into space, regardless of cost. Even if I'd never see the end of the journey, I'd be a part of the greatest adventure humanity had ever undertaken.
<bot>: Would you sign up for a generation ship knowing you'd die on the way but that your descendants would possibly set up a space colony?
