ARM - Asteroid Retrieval Mission
Great paper here. I'm still going through it as it has plenty of detail.
The de-tumble is to be done with hypergolic fuel.
SEP spacecraft is to be sized for Atlas 551 (17995kg).
12000kg of Xenon.
I like the concepts for the capture method. Pac Man to gobble up the asteroid 8)

The evolution of thinking about this is nice to see. "[...] the amount of additional propellant to insert into the utilization/storage orbit increases significantly as the asteroidal return mass becomes large. Performing an initial mission with a smaller mass can help increase the probability of mission success." Combined with frequently qualifying "a small NEA" with the phrase, "or part of a large NEA," this paper begins to blur the distinction between the highly-challenging "asteroid retrieval" and the more-achievable "asteroid sample return" mission classes.

Excellent observation about the continued blurring of the purpose, allowing success to be deemed at each point along the way.
With the heist, the government continues to solidify its position as the entertainment division of the military-industrial complex.
Details at eleven.

Not even very good entertainment at that.
SEP using prop launched from Earth is a dead end IMO.
