Tracking and data systems support for the Helios project. Volume 3: DSN support of Project Helios May 1976 - June 1977

Abstract

Spacecraft extended mission coverage does not generally carry a high priority, but Helios was fortunate in that a combination of separated viewperiods and unique utilization of the STDN Goldstone antenna have provided a considerable amount of additional science data return, particularly at key times such a perihelion and/or solar occultation
