Intro to Astronomy
... Hundreds of robotic spacecraft have been launched for many missions around our solar system. Most of these do not return to the Earth. Typically, spacecraft will use the gravity of the Earth or other planets to send them farther out into space. The method is called “gravity assist” or “sling-shot”. ...
