In-reply-to: csin!cjh's message of 4 Dec 1981 11:45:01-EST To: Space-Enthusiasts at MIT-MC cc: Lynn.es The costs of getting mass into even LEO is strictly a result of having to carry chemical fuel with you during launch. The cost of say electrical energy to launch into orbit is pennies per pound, if you don't carry the fuel with you that you are burning. Once we harness high energy fuels (nuclear) or learn to beam up the launch energy, space colonists may be no more select and privileged than automobile drivers. /Don Lynn ------------------------------ Date: 7 Dec 1981 1556-EST From: JoSH Subject: Orion To: space at MIT-AI A description of the Orion project is given in Freeman Dyson's excellent "Disturbing the Universe." --JoSH ------- ------------------------------ End of SPACE Digest ******************* ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
