Some questions on the basic hardware of the Voyager spacecraft:
1. From which material was the decahedral space bus made ( Aluminium ? ) 2. Exact weight of the spacecraft - literature gives numbers between 792 and 825 kilograms ? Some additional questions: 1. The Deep Space Network of worldwide antenna sites wasn't sufficient to collect the faint signal of the distant spacecraft once beyond Saturn ... I know that the twenty-seven 25-meter steerable radio antennes of the Very Large Array in New Mexico were linked with DSN ... when was this done exactly? ( 1989 Neptune encounter only ? ) 2. What is the actual telecommunications time-lag 1-way to Earth (after having passed the bow-shock ) |

Gold is very resistant to corrosion (like from atomic oxygen in LEO, or in this case prolonged passage though an interstellar gas cloud), and an excellent conductor of both heat & electricity (therefore resistant to spot-arcing or uneven thermal flex). It's a good material for this application.
-------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
