Transit 5E-1, International Designator 1963-038C, is an artificial satellite of the United States Department of Defense and launched in September 28, 1963, aboard a Thor rocket from the Vandenberg Air Force Base.
It was launched to a polar orbit, from where it did geomagnetic and geodetic measurements. Electrical power was produced by four solar panels. After August 1969, the satellite did measurements infrequently. The last data were transmitted in November, 1974.
