Jet Propulsion Laboratory (U.S.). Imaging Instrument Team.

Mariner Venus Mercury '73, MVM '73, was launched November 3, 1973 when it became known as Mariner 10. Its mission was to encounter Venus and then Mercury in a series of flybys. It was the first mission to use the gravitational attraction of one planet to accelerate a spacecraft in flight to reach another planet. During its flybys of Venus and Mercury, Mariner 10 returned a total 8200 images including 3700 of Mercury during 3 flybys. The Imaging Instrument Team, headed by Bruce Murray at JPL, was responsible for the operation, health, and calibrations of the entire communications and information systems of MVM '73.
