NASA's Voyager 1 spacecraft finally phones home after 5 months of no contact
Thirty-five years after its launch in 1977, Voyager 1 became the first human-made object to leave the solar system and enter interstellar space. It was followed out of our cosmic quarters by its space-faring sibling, Voyager 2, six years later in 2018. Voyager 2, thankfully, is still operational and communicating well with Earth.
