What is the primary trade-off in using electric propulsion for spacecraft compared to chemical rockets?
Electric propulsion provides higher thrust than chemical rockets but consumes more fuel, limiting mission duration.
Electric propulsion offers higher fuel efficiency but produces lower thrust, making it better for long-duration missions rather than rapid maneuvers.
Electric propulsion can replace chemical rockets for all types of space missions without any performance compromises.

What is the primary trade-off between chemical rockets and electric ion thrusters in spacecraft propulsion?
Chemical rockets are more fuel-efficient than ion thrusters but provide less thrust.
Ion thrusters rely on atmospheric oxygen to generate thrust, limiting their use to low Earth orbit.
Chemical rockets provide high thrust but consume fuel quickly, while ion thrusters offer low thrust but are highly fuel-efficient.

What is the primary trade-off between chemical rockets and electric propulsion systems in spacecraft?
Chemical rockets are more efficient than electric propulsion but provide less thrust.
Electric propulsion systems can generate high thrust quickly, making them ideal for launch phases.
Chemical rockets provide high thrust but low efficiency, while electric propulsion offers high efficiency but low thrust.

Rocket propulsion harnesses Newton's third law to power spacecraft through the vacuum of space

Why is rocket propulsion effective in the vacuum of space, unlike conventional aircraft propulsion?
Because it expels mass backward to produce thrust without needing air to push against
Because it uses air from space to generate lift and thrust
Because it relies on magnetic fields in space to propel the spacecraft
