Voyager 2 has to be one of the most amazing pieces of technology ever built. Launched over 30 years ago, the thing is still operational, responsive, and sending back data about the farthest outer reaches of our solar system.
It brings a warm feeling to my heart; technology that was created in a time when engineering was more about getting it right and less about doing it in a monetarily efficient way.
Float on, little Voyager.
