Abstract
The first of two Helios spacecraft, built by West Germany, was successfully launched from Cape Kennedy on December 10, 1974 and is now enroute to an unprecedented 0.31-astronomical unit (AU) perihelion in mid-March 1975. This article describes the DSN support starting with the prelaunch activities and carrying through the first three critical days of the mission.
