Apparently this technology has been around for decades and yet it looks like they are only just getting started, Ad Astra was founded over 5 years ago, why has it taken them this long? Also from the Vids on youtube and articles i have read about the VASIMR, why haven't they test this on a nuclear power source yet, nasa has over a decade ago on and ion engine.
some light reading

some of those might explain it a bit better while some call it an ion engine it actually isn't one. it gets much hotter supplying more thrust, ~> plasma engine. typical ion engines are low thrust. they just don't have much power.

ion trusters

the advantages of both types over high power chemical rockets is less over all reaction mass needed (fuel) and in VASIMR's case it can use almost any gas. though some provide better results than others. argon is the one i see used most often. greatly simplifies fuel delivery, and no flammable chemicals ^_^

ion engines are tried and tested (in most types) technologies, been around for years, VASIMR's brand new...of course they're going to go slow and test the crap out of it...a failure for any reason could be catastrophic if a crew is relying on one.
