Dear Cheap Astronomy – Is in situ resource utilization really worth the trouble?
Here at Cheap Astronomy we tend to say disparaging things about in-situ resource utilization, but usually in response to suggestions that if we want to land on Mars all we have to do is make rocket fuel out of in situ resources to take off again. While ostensibly true, a substantial amount of infrastructure would be needed to both source and refine the ingredients to make that fuel and you’d probably want to experiment with a few different methods, expect a few false starts and have a few trial runs before you’d actually put people on your launch vehicle.
Dear Cheap Astronomy –
The Space Economy is defined by the OECD as the full range of activities that create value and benefits to human beings in the course of exploring, researching, understanding, managing, and utilising space. As we’ve previously discussed both on this and the fabulous Science on the ISS podcast, exploring, researching and understanding space are important activities– but if we are really going to move forward, more of the managing and utilizing space need to come into play.
Bio: Cheap Astronomy offers an educational website where you’re only as cheap as the telescope you’re looking through.
