The Jet Propulsion Laboratory (JPL) is a research and development center and NASA field center in Pasadena, California. The JPL is owned by NASA and managed by the nearby California Institute of Technology. The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating NASA's Deep Space Network. Among the laboratory's major active projects are the Mars Scien...

The radio transmitters/receivers aboard spacecraft are used for more than just communicating planetary data and receiving commands. A number of scientific experiments can be conducted by analyzing radio signals sent back from the spacecraft. Radio signals from a spacecraft can be analyzed during the passage of that signal close to a planet. The signal is usually bent, delayed, obscured or reflected by the planet. The measurement of these alterations to the signal allows scientists to extract inf...
