Summary
The asteroid redirect vehicle demonstrates the “gravity tractor” planetary defense technique on a hazardous-size asteroid. The gravity tractor method leverages the mass of the spacecraft to impart a gravitational force on the asteroid, slowly altering the asteroid’s trajectory. The demonstration is conducted after capturing the boulder and is referred to as the “enhanced gravity tractor” because the additional mass of the boulder enhances the force that can be transmitted to the asteroid.
