Why develop a technology to make fuel in space when the
whole concept of using chemical rockets to go to the planets (with humans onboard) is terribly flawed, too expensive, too slow, too backward? http://www.physorg.com/news4018.html |

Ion, solar wind, space elevators, and other methods are being investigated (ESA's SMART-1 to Luna, NASA and the Planetary Society's work on solar sails, etc). Of the existing set of alternatives, only ion drives are currently rated as space worthy. AND, due to ion drive's low thrust, it is not yet practical for human spaceflight; while a chemical rocket takes ~7-8 months to get to Mars, an ion rocket could take YEARS - far too long to ask our brave astronauts to wait for planet-fall! Yes, we would like starship-like capabilities, like, yesterday! Enterprise is not yet here, I'm afraid. ***** May you have clear skies & a star to steer by! ~M.

And how else are we to get to the other planets?
