Days is ridiculous. A few months instead of the years chemical rockets would take is probably a better estimate. The big advantage to VASMIR is that, unlike the Deep Space 1-style ion engine you can get reasonable thrust and a high specific impulse at the same time.

When they say days they mean 40 days, not a "few" days.

That's kind of misleading, isn't it? I mean, by the same token days could mean 400 days or 4000.
