USA Today (Oberg): “Think outside moon-Mars box: Maybe visit asteroid”
USA Today (Oberg): “Think outside moon-Mars box: Maybe visit asteroid”
USA Today, Jan 14, 2004 http://www.usatoday.com/news/opinion...14-oberg_x.htm By James Oberg The moon race of the 1960s was fueled by national anxiety about what the world would become if the Soviet Union grabbed a permanent lead in space exploration. So President Kennedy set a vision for the USA to reach the moon first. etc |

The asteroids also have better mineral resources. The ones I find most interesting are possible volatiles: water, ammonia, & hydrocarbons. The man on the street may be impressed that there are metallic asteroids with high grade iron, nickel, copper, silver, gold and platinum ore. An effective asteroid sales pitch could be made to the public. -- Hop David http://clowder.net/hop/index.html |

A moon has much more clout than some rock flying through space, even if it's more challenging. It's a psychological kind of thing. Actually, an asteroid mission would fit well in the Moon/Mars plan. After doing lunar missions and before a Mars mission, an asteroid mission would give you the chance to test many of the systems needed for Mars, but without the huge Mars gravity well. Visiting Martian moons is a possibility too, since they look to be captured asteroids. You have to deal with the gravity well of Mars, in that you have to enter and leave Mars orbit, but the lander itself doesn't have to directly deal with the gravity well. For either of the above missions, you'd use your Mars transport, but could use your proven Moon lander for the asteroid or Martian moon landing.

The best asteroids for such missions are called Phobos and Deimos.

What I'm about to say is heresy in much of the space advocacy community, but I think asteroids have more to do with our future in space than does Mars. -- Regards, Mike Combs ---------------------------------------------------------------------- We should ask, critically and with appeal to the numbers, whether the best site for a growing advancing industrial society is Earth, the Moon, Mars, some other planet, or somewhere else entirely. Surprisingly, the answer will be inescapable - the best site is "somewhere else entirely." Gerard O'Neill - "The High Frontier" |

Cheers, - Joe ,------------------------------------------------------------------. | Joseph J. Strout Check out the Mac Web Directory: | | http://www.macwebdir.com | `------------------------------------------------------------------' Much of the velocity matching can be achieved via Martian aerobraking. So delta V wise they're near the top of the list. There have been some hints suggesting water within the Martian moons. But we don't really know. That's why I advocate a fleet of prospector probes to determine what resources are within easy reach. Phobos and Deimos should be checked out as well as Nereus, 1979 VA. These are my favorite asteroids: http://clowder.net/hop/railroad/1_5/1_5.html (these asteroids have a 1.5 year period. There are also 1_33 and 1_25 pages. some of the 1.25 year asteroids have a very low delta v.) -- Hop David http://clowder.net/hop/index.html |

I listened to his speech today (despite the fact that news sources like CNN claimed to know exactly what he was going to say days in advance) and low and behold he set goals that go beyond the moon and Mars. He called them 'stepping stones' to the cosmos and explicitly said we should explore worlds beyond those two places. -McDaniel |
