Discoveries in 50 years

In the environment of discovery, engineers are going to make better investigation robots so they can study other planets of the solar system besides Mars, and maybe study outside of the Milky Way. Just imagine knowing a lot more about Neptune, or how the solar system was created, or even another planet to live. And, let's be honest; our planet is not going to last for long. Furthermore, they'll be traveling through space so they can watch the discoveries with their own eyes.
