NASA launched Voyager 1 in 1977 to study the outer Solar System and eventually interstellar space. The spacecraft, still travelling at 64,000 km/h (40,000 mph), is the most distant human-made object from Earth and the first one to leave the Solar System. Operating for 42 years, 9 months and 22 days as of today (28 June 2020), it receives routine commands and transmits data back to the Deep Space Network.
