Do you know where current ion thrusters sit in terms of isp?

  Some of the better ones that are actually in use get in the range of low thousands, like ~3k or so, but keep in mind that the thrust is so low that even just getting to the Moon takes months. They're only suitable for unmanned craft, and even then, only after you get into orbit and if you don't care about taking potentially many years to get somewhere outside the local SoI.

    Ah, thought it was higher, thanks!
