Galileo in High Bay 1

White walls and scaffolding had become a common sight in the High Bay 1 clean room in JPL's Spacecraft Assembly Facility by the time the Galileo orbiter was being built. This photo from Nov. 1, 1984 shows that gowning requirements had also become more complex.

Note the fully-opened high-gain antenna; an emblem on the clean room's Wall of Fame depicts it partially opened, as it was at Jupiter.
