Stefano, you realize there are two completely different things being<br>
discussed here, ja?</blockquote></div><br>Yes, all that is crystal clear. Vasimir plasma propulsion may work with solar energy in the ISS, but requires something juicier for a Mars trip. Plenty of information available on the Web in this respect. And we can expect the same reactions we had with the Cassini's flyby.<br>
<br>"Of course, we would need a lot more power to effectively use a
Vasimr-powered rocket, and solar cells just won’t cut it in deep
interplanetary space. So what would we use? A nuclear reactor, of
course. We woudln’t need a large one; in fact, the nuclear reactor
found on the <i>Los Angeles</i> class attack submarine would be the
ideal size to power a Vasimr plasma engine. Not surprisingly, Dr.
Franklin Chang Diaz, the CEO of Ad Astra and a seven-time Space Shuttle
astronaut, agrees that nuclear fission would be the best available
solution. His analysis has suggested that a 12-megawatt Vasimr
spacecraft could reach Mars in as little as 39 days, a far cry from the
nine months it currently takes to send unmanned craft from Earth to the
red planet."
