A Hypervelocity Asteroid Intercept Vehicle (HAIV) is a spacecraft being developed by NASA to deflect dangerous Near Earth objects (NEOs) such as comets and asteroids that threaten colliding with Earth.[1] The vehicle is intended to use powerful explosives, such as nuclear bombs, to deflect the NEO by detonating on the surface, thus changing its trajectory to miss Earth. This method of asteroid impact avoidance is intended to be used on dangerous NEOs detected within a short time frame (less than 5 years) before a possible impact event with Earth. The idea came about when asteroid detection improved. Since then, scientists and engineers have sketched a design for an HAIV.
