[ RadSafe ] space propulsion and shielding

[JPreisig at aol.com]

Mike/Radsafe,
 
     google  haunebu
 
 
     The schematics of the haunebu spaceship on the  internet give 
performance velocities which are quite high.  There  apparently were multiple 
versions of the Haunebu.

I am a  HUGE fan of science fiction (in fact, I have written some), and 
comet/asteroid  mining is a staple of the genre, but short of some propulsion 
system vastly  better than what we have available now I see little hope for 
industrial  application.  The problem is that everything is moving really 
fast  compared to everything else, and it is all a long ways away.  The recent  
probe to a comet took about 10 years to get there, and that was for a comet 
 with a favorable orbit.  

I think that it is much more likely we  will develop cheaper ways to get 
things out of the gravity well, and that will  make visiting other parts of 
the Solar System much easier.  My bets are  on a space elevator, though there 
are non-trivial technical issues, not the  least of which is that it will 
take days to go through the Van Allen Belt,  rather than minutes, and 
radiation exposure could be  significant.

Given our recent ability  to latch onto comets, I believe it wont be long 
before we are able to do some  mining/processing of their materials to 
construct hydrogenous shielding in  situ, (enabling spacecraft launches to remain 
as lightweight as  possible)

Fingers crossed!
