What's the deal going to be with Voyager after leaving our Solar System?? What are we hoping to gain and what is the probability that Voyager will survive after Uranus and Neptune?? If I am asking ridiculous questions, please satisfy my ignorance anyway. Brought to you by Super Global Mega Corp .com
