The Jet Propulsion Laboratory space exploration: Past, present and future

The most recent scientific results from space exploration carried out by the Jet Propulsion Laboratory (JPL) are discussed. To aid understanding of these results, a brief background of JPL's history is presented, followed by a description of the Deep Space Network, JPL's system of antennas which communicates with spacecraft. The results from the missions of Voyager 1 and Voyager 2 are described. The atmosphere, rings, satellites and magnetospheres of Jupiter, Saturn, Uranus and Neptune are discussed with particular emphasis on novelty of the discoveries and the challenges encountered in explaining them. A brief discussion of the impact of spray research upon space exploration follows. This is because most recently launched missions used liquid fueled rockets to escape Earth's gravity. A summary of future missions and the National Aeronautics and Space Administration's new policies is presented in the conclusion.
