"I cannot see how it could be faster to get He3 from asteroids when
the moon is much closer. " -- Richard Brooks

"..easier target to reach logistically than the moon.. takes
considerably less energy to land on and take off from an asteroid
than it does the moon.. lack of gravity also makes the mining
process much easier.."

There is no need to land on the moon. Material can be shot up by mass drivers.

"... there are some (NEAs) for which it would be easier to effect a
spacecraft rendezvous and landing than it would for the moon ..."

"Some half a million asteroids 100 yards across or larger orbit the
Sun along paths that cross or come close to the orbit of the Earth.
In principle, it is easier to reach about 100,000 of these "Near
Earth Asteroids" and return a payload to the Earth than it is to
return the same payload from the Moon."

Enjoy.

All of these except the first reply to SOME asteroids. I was asking about
most of them. Besides earth-passing asteroids are here today and gone
tomorrow. A lot safer to work on the moon.

Besides right now we have not gotten a person even to Mars, let alone the
Asteroid Belt.
