Thirty six years ago this month, I commenced my senior year in college and Voyager 1 was launched. Yesterday’s article in the Washington Post stated, 

The tireless Voyager I spacecraft, launched in the disco era and now more than 11 billion miles from Earth, has become the first man-made object to enter interstellar space.

Instruments on this spacecraft, powered by the radioactive decay of Plutonium 238, are expected to continue operating until 2025 – pumping back information from where no man has gone before.  Pretty cool stuff!
