My dad worked on the Pioneer 10 and 11 space probes. Specifically the frame that held them to the rocket. It had to be light, strong, flexible enough to isolate them from the rockets vibration, and not resonate either. Design, fabrication, and testing took 18 months. And he wasn't the only engineer working on it.
