he Asteroid Redirect Mission (ARM) will also allow Nasa to demonstrate many

human missions to deep space and begin a new era of spaceflight," said Nasa

techniques that it could use to throw an asteroid off course if it were

Perhaps the most important part of a successful ARM mission would be a small asteroid more-or-less permanently in orbit around the Moon, and thus vastly more accessible than any other asteroid. If we are ever to mine asteroids, it would be extremely helpful to have one (or more) in a convenient orbit to test out techniques. Being days away is a lot better than being months (or years) away whenever trying to actually do something.

Agreed, though I suspect if we look hard enough, we'll find asteroids already lying around on the surface of the Moon. Accessing these would be much easier, and almost certainly provide more material, than retrieving a boulder from a NEA.

Still, it's an ambitious plan and I hope it goes forward. Industry should step up and do the easy things. :)

No? It seems a lot easier to me. The gravity well is quite light (look
at the size of the Apollo LM). Just enough to keep your tools from
floating away. And the "lot shorter" is a big, big deal -- we're
talking about resources that are always a few days away, vs. resources
that are often on the other side of the Sun. The logistical
difficulties of retrieving material from a NEA are immense. You've got
to either set up an operation that can be autonomous for years at a time
(because the object is way out of reach), or be prepared to do a mad
dash&grab operation where you extract all the resources you want within
the very narrow window during which the object is near Earth.
I certainly believe we'll manage it someday, of course. But if you show
me company A, planning to retrieve stuff from the Moon, and company B
aiming to retrieve stuff from NEAs, I'm investing in company A for sure.
Best,
