In less than five minutes, a NASA scientist gives a clear and fascinating answer to a question about space or Earth science or technology. Want to know about black holes? gas giant planets? the Big Bang? where the Moon came from? other weird ideas and observations you've heard about? Tune in to Space Place Musings to be enlightened. en-us no copyright clean Anil Natha Anil.Natha@jpl.nasa.gov How does gravity work to hold the solar system together? Clear and simple explanation of the gravitational forces that keep the planets in their orbits, rather than falling into the Sun or flying off into interstellar space. Also, explains how interplanetary spacecraft can take advantage of the gravitational forces to speed up its journey.
