This artist's concept depicts the Inertial Upper Stage booster rocket firing shortly after its deployment from the shuttle Atlantis. Galileo's complex trajectory to Jupiter flung it by Venus once and then back to Earth for two fly-bys. Each pass added kinetic energy to the spacecraft, increasing its velocity so that it could reach Jupiter with a relatively small amount of fuel.
