A few months ago I talked here about the Voyager 1 space probe, the most distant of all objects made by humans.
Launched on September 5, 1977, by NASA, Voyager 1 became the farthest-traveling human-made object on February 17, 1998. Despite the enormous distance separating us from this probe with its now very outdated technology, NASA has managed to maintain contact with Voyager 1 through its Deep Space Network via its three mission tracking complexes: Goldstone (California, USA), Canberra (Australia), and Robledo de Chavela (Madrid, Spain). Currently, the probe is about a light-day away from us. Its already faint signal will likely disappear into the vastness of space in the coming years.
It is very likely that Voyager 1, like four other space probes sent into space by NASA (Voyager 2, Pioneer 10, Pioneer 11, and New Horizons), will outlive humanity itself, if nothing interferes with its long flight. These probes will then become tangible proof of our existence. A few days ago, the channel NullSpace published a fabulous video imagining what Voyager 1's journey might be like when we are no longer here, at a distance difficult to conceive and seeing things that humanity will possibly never be able to contemplate:
