What is the most commonly used thruster type for satellite on-orbit propulsion?

• A. Ionic thruster
• B. Chemical monopropellant
• C. Solid rocket motor
• D. Electric thruster

Answer: (B)

The most commonly used thruster type for satellite on-orbit propulsion is the chemical monopropellant. This type of thruster operates using a single propellant that, when decomposed, generates thrust. It's favored in many satellite applications due to its simplicity, reliability, and the relative ease of handling the propellant. Monopropellant thrusters can provide a significant amount of thrust in a compact design, which is particularly beneficial for satellite maneuvering and station-keeping operations in orbit, where precise control is essential. Many satellites, especially those in low Earth orbit, utilize chemical monopropellants because they can produce immediate and effective thrust with relatively straightforward propulsion systems, making them ideal for tasks that require quick responses and controlled maneuvers. The straightforward design and established use of monopropellant technology contribute to its popularity within the space industry.
