Re: Our next goal in space?
Distance isn't everything in space exploration (actually it isn't very much); but the delta v to get to and from AA29 is very low indeed. Because an asteroid that small is essentially a microgravity environment, you don't need designated landing systems either: just a habitation module; a re-entry capsule a relatively low-speed Earth return; and enough grunt to get you there & back - you could even do a test flight to the asteroid which is essentially a manned flyby mission that does away with the return rocket by coming back on a free return. An object to keep an eye on.
