OCR: GRAVITY SLINGSHOTS A Gravitational Slingshot technique that uses the gravitational pull of planet to change the speed and direction of small body. such space probe The probe sent on hyperbolic path that will pass close to fas t moving planet Relative the planet the probes velocity of approach ( is equal to it velocity of recession y) However because the planet itself 1 : moving vp), the probes paads relative to the solar system has been changed As the probe gains speed and momentum relative to the larger solar system the planet will also lose equal but opposite momentum relative the solar system. The planet's velocity change is usually minor because of itc cuperior mass Under (very close pass near par abolic entry pue exit) the velocity gain of the probe could he equal to twice the planet' ...
