re: interesting idea..but can they really pull it off?
while i'm at it....could someone please post some in depth info on the VASIMR engines mentioned in this article for me.
also...when and if they made a feasibility test and it turns out that this wouldn't work..what would they do with the tug? could there be orbital emergency docking applications for the shuttle applied here? maybe somehow salvage the money dumped into this thing and convert it to a repair tug or some other "feasible" applications?
