Best asteroids to colonize?
Some of the criteria I'm using:
Low inclination Perihelion near 1 A.U. Close to earth resonant orbits (good launch opportunities should reoccur on a regular basis). Asteroids with 5/4 year orbits: http://clowder.net/hop/railroad/1_25/1_25.html Asteroids with 4/3 year orbits: http://clowder.net/hop/railroad/1_33/1_33.html Asteroids with 3/2 year orbits: http://clowder.net/hop/railroad/1_5/1_5.html Asteroids with 5/3 year orbits: http://clowder.net/hop/railroad/1_66/1_66.html Asteroids with 2 year orbits: http://clowder.net/hop/railroad/2/2.html If any of the asteroids have volatiles, they might be able to export water, fuel and building materials to LEO. Also many of the above asteroids have close to 1.52 A.U. aphelions and so may occasionally have opportunities to ferry people & cargo to Mars. I am confused about claims of low DVs to land on asteroids. Most of the ones I looked at seem to require greater then Moon escape velocity DV to match orbits. About 3/4 of the way down http://www.permanent.com/t-theory.ht...eroid-missions the Permanent writer says ". . . the asteroid 1982DB, . . . needs a delta-v of a mere 0.06 km/sec (i.e., 60 meters per second, or 130 miles per hour) to be captured by the Earth-Moon system." I wish I know more about how low DV asteroid missions could be accomplished. Hop http://clowder.net/hop/index.html |
