NASA's twin Voyager spacecraft completed 45 years in space.
These Voyager satellites have an eight track tape recorder for storing data which is much less than today's phone
The data captured by these satellites sent back to earth at 38000 times slower rate than a 5G internet connection.
Voyager 1 and 2 were launched on Sep. 3, 1977 and Aug 20, 1977.
It is interesting to note that NASA's Voyager 2 was launched before Voyager 1.
Jet propulsion laboratory is in charge of tracking their journey and these are the first to go into interstellar space.
Due to its higher speed Voyager 1 reached Jupiter and Saturn earlier than Voyager 2 although 2 was launched before 1.
Both satellites provided plenty of information about Jupiter and Saturn.
