What drawback of ion propulsion?
A major limiting factor of ion thrusters is their small thrust, which however is generated at a high propellant efficiency (mass utilisation). The efficiency comes from the high exhaust velocity, which in turn demands a lot of energy, and t... Read More »

How suitable is radium for ion propulsion?
It may be possible to bombard Radium 15 with protons, creating Radium 16. Radium 16 has a fast decay rate. This would release large amounts of energy. Read More »

Who says it's not? Ion propulsion has worked quite well on the DS1 space probe. It's much more mass-efficient than chemical propulsion. DS1 gets 10 times as much acceleration from a given mass of fuel as a chemical rocket. That's a somewhat...

Speed is limited by the total momentum that can be imparted to the ions as they are expelled from the spacecraft. Figure out the mass of your spacecraft, the mass of ion material, and the velocity that the ions will be expelled. Then use co...
