Assuming that it is possible to build a self sustaining colony on the moon or Mars, would it pose a danger to earth because it would be easier to launch projectiles from them toward Earth than it would be to launch projectiles from the Earth to the moon or to Mars?
If there exists a self sustaining colony in geosynchronous orbit, what relatively inexpensive things could be done from there to threaten the earth? - Sue - Friendfeed is best
I wonder if governments might lack enthusiasm about manned space colonies because of the danger they might bring. - Sue - Friendfeed is best
