Probably not, since we suspect many asteroids of being volatile-rich. Fuel and reaction mass, all in one. I was unable to find any information on D/H ratios in a quick glance through my copy of _Asteroids_, but the Phobos mission may provide info in short order, if their mass spectrometer determines D abundance. This is aside from there being no need to accelerate at 1G in either direction for other reasons. -- Jon Leech (leech@cs.unc.edu) __@/ "Totally bounded: A set that can be patrolled by a finite number of arbitrarily near-sighted policemen."
