Trying to understand ion thrusters a little, I started looking at https://en.wikipedia.org/wiki/Ion_thruster#Propellants where I saw:
The CubeSat Ambipolar Thruster (CAT) used on the Mars Array of Ionospheric Research Satellites Using the CubeSat Ambipolar Thruster (MARS-CAT) mission proposes to use solid Iodine as the propellant to minimize storage volume.
Reference  says:
"MARS-CAT Mission Implementation". www.marscat.space. University of Houston College of Natural Sciences and Mathematics. Retrieved June 25, 2015.
But that link doesn't go anywhere for me.
Question: What is a Cubesat Ambipolar Thruster and how does it work? Is this thrust to get the cubesat to Mars, or to maneuver in Mars' ionosphere after getting there, or both?
edit: CAT is definitely written about, a quick search already gives
So how close is it to seeing a real cubesat mission to Mars?
