When I was a teenager (45 - 50 years ago), there was a mission launched where the main parabolic high gain antenna did not open fully. What was this mission and how did they solve the antenna problem?

A lot more to it than that -- see https://www.nasa.gov/audience/formedia/fact..._factsheet.html and (for more technical details) https://descanso.jpl.nasa.gov/monograph/ser...er4--141029.pdf .

Compressed data was stored on the tape recorder; some particles and fields data was stored in memory buffers. There was a tape recorder anomaly early in the mission that would have further degraded data return, but they managed to work around it.
