Earth-Mars Trajectory Calculation Collection, 1964.

http://www.worldcat.org/oclc/733100053

The collection consists of a 905-page photo-reduction of a computer printout of a trajectory calculation for an Earth to Mars flyby, a 306-day flight launched December 5, 1964. The computation of the trajectory used an early version of TWIST, a software program currently used by JPL for trajectory calculations. The printout shows the ephemeris of Mars and Earth as numerical values, with Equatorial coordinates. The printout is labeled "IBSYS-JPTRAJ-SPACE 111464." This calculation may be an alternate trajectory for the Mariner 4 mission. Mariner 4 was launched on November 28, 1964. A midcourse maneuver was made on December 4, 1964, and the spacecraft made its closest pass to Mars on June 14, 1965. The spacecraft returned data until October 1, 1965.

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...
