Most of the stuff I read are way over my head. Or maybe, I was daydreaming about space travel, and all the Sci-Fi books I read. But to read through the whole thing is like being given a ticket to take seat on a starship bound to . . .wherever.

ION THRUSTERS IN NASA MISSION REDRAW THE BOUNDARIES OF SPACE EXPLORATION

"Ion propulsion has even furthered the possibilities of human space exploration. In future missions, it could be used to send supplies back and forth to astronauts on Mars or other distant locations.

However, ion-powered engines are only useful for certain kinds of space missions. For transporting humans to other worlds, it is too slow. It would take Dawn four days to accelerate from zero to 60 miles per hour. Designed for patient missions, ion thrusters are too costly and complex for straightforward missions to destinations such as Mars or Venus, Rayman says."
