How long does a ion engine last?
The first ion thrusters did not last very long, but the ion thruster on Deep Space 1 exceeded expectations and was used more than 16,000 hours during a period of over 2 years. The ion thrusters being developed now are being designed to operate for 7 to 10 years.
Do ion thrusters work in atmosphere?
Ion thrust engines are practical only in the vacuum of space and cannot take vehicles through the atmosphere because ion engines do not work in the presence of ions outside the engine; additionally, the engine’s minuscule thrust cannot overcome any significant air resistance.
Do ion thrusters work on Earth space engineers?
However, unlike Atmospheric thrusters which can only work in an atmosphere, Ion thrusters work best in a vacuum, and grow significantly less powerful as they enter thicker atmospheres….Ion Thruster.

How long is the ion drive to Mars?
Hermes (Ion Drive) So, with a constant acceleration of 2mm/s2 it will take 245 days for a rocket with an ion drive to reach Mars.
How fast is an ion drive?
200,000 miles per hour
The good news, though, is that the (eventual) max speed of a spacecraft propelled by an ion drive is in the region of 200,000 miles per hour (321,000 kph).
What fuel do ion thrusters use space engineers?
There are three types of thrusters: Atmospheric thrusters which are electrically powered and only work in the atmosphere of a planet, Ion-based thrusters that use electricity and work in vacuum, and powerful Hydrogen thrusters which require Hydrogen as a fuel.
How does an ion engine work on a spacecraft?
Finally, an neutralizer sprays electrons into the exhaust plume at a rate that keeps the spacecraft electrically neutral. An electromagnetic ion engine also works by ionizing a fuel. In this case a plasma is created that carries current between the ionizing anode and a cathode.
Why are ion engines limited to 100 km/s?
The limit isn’t due to power, but to engine lifetime and fuel limits. Ion engines produce very little thrust, so in order to reach speeds of 100km/s they must accelerate continuously for months or years.
Are there any technical problems with ionizing fuel?
There are some minor technical problems with efficiently ionizing the fuel and cooling the engines, but the biggest roadblock of which we are currently aware is that the large ionic current passing through the engine will cause enough erosion to destroy the engine.
