Lessons Learned - Galileo High Gain Antenna (HGA) Failure (1991)
Year: 1997
Abstract: Abstract:
The Galileo spacecraft High Gain Antenna (HGA) was to open like an umbrella, but it never reached the fully deployed position. The failure was attributed to the design of the rib retention mechanism. Recommendations involved the design of preloaded mechanisms, lubricant selection and use, hardware robustness, and fault tolerant design of one-shot, non-redundant, mechanisms.
