"Wet" Asteroids Could Supply Space Gas Stations

FleaPlus writes "Water ice was recently discovered on the large asteroid 24 Themis, and Space.com discusses proposals for producing fuel from asteroid ice. NASA and the President recently announced plans for robotic precursor missions to asteroids (and a human mission by 2025), as well as a funding boost for R&D to develop techniques like in-situ resource utilization. Since most of the mass of a beyond-Earth mission is fuel, refueling in orbit would be a huge mass- and cost-saver for space exploration (especially if fuel can be produced in space), but a large unknown is how to effectively extract water in an environment lacking gravity."

    ... it seems like a more suitable source of gas would be Uranus.

    Do you have to actively work to create sentences like this? Is there some kind of system of analysis and theory behind poor sentence construction that you employ? I can't imagine anyone would actually be able to write like that without concerted effort and thought put into it, and yet you trolls do it every day. Perhaps it is an under-appreciated art.

    It's how yobs (thugs/losers/hoodies) in the UK speak. Average IQ pushing one digit, average time from hitting puberty to pregnancy (female) about 9 months, average time from hitting puberty to contracting a venerial disease (both genders) about ten minutes.

    In fairness to the grandparent, that kind of verbiage has also filtered into other (non-destructive) youth groups, in kind of a mish-mash of UK-yob and US-gangsta speak that for whatever reason is percieved as "cool" among the under 14s. Perhaps s/he fits into that category. Otherwise, you're right, it takes real talent for someone to fuck up a perfectly good English sentence like s/he did.
