The Space Program - A Modest Proposal, Paul Spudis
"I'm at a loss to explain why one aspect of the ARM mission hasn't been discussed in the media: seeing that advocates of the ARM think nothing about re-arranging the architecture of the Solar System for their convenience, environmental activists might object to the very idea behind the mission. We can't get to a near-Earth asteroid with the Orion spacecraft and the Space Launch System (SLS), so let's just drag the asteroid to us! Imagine a defenseless rock, innocently tumbling its way through space, only to be snagged, bagged, and defiled appropriated and exploited by arrogant, human interlopers. There ought to be a law!"
