sling shot?

Question

Is the sling shot effect a possiblity if space travel was ever perfected, and how much energy would actually be needed to acheive this?
Im just curious

Answer 1

Yes.

The voyager probes have alreay used this to speed up and redirect to next planet

Answer 2

It can be used, and has. Several space probes have used it to gain speed. Some have used it several times, at several planets. It won't work for interstellar travel, though - the distance between stars is so far that any voyage would still be measured in thousands of years.

Answer 3

i like, for once, someone that uses their mind and head other than a place to put a hat on. to answer the question directly,
nasa, as well as other space agencies have used the ability of other planetary bodies to propel our probes, satellites, and other material into space using the gravitational force of extraterrestrial means. the speed of breakaway depends on the gravitational force of the body it is trying to use. it, in effect, uses less energy to solve some of the way space travel is accomplished. keep studying the stars, they are out there for us to study, and learn.
