Preparing for Voyager Missions

1. What were the primary scientific goals of the Voyager missions when they were launched in 1977?

2. Describe one significant discovery made by Voyager 1 during its flyby of Jupiter and explain its impact on our understanding of the solar system.

3. Explain the importance of redundant systems and fault protection mechanisms in spacecraft design, using Voyager 1's recent communication challenge as an example.
