Voyager Sisters - R.I.S. (Rest in Space)
Voyager 1 was launched into space in September 1977 with the primary target to explore Jupiter and Saturn and their moons and rings. It is today the farthest human-made object from Earth, with a distance of about 22.6 billion kilometers from our Sun, or 150 times farther away from the Sun than Earth. Voyager 1 was also the first human object to enter interstellar space about 10 years ago.
The reason for the lost contact is lack of power from the three radioisotope thermoelectric generators, that is needed for the Voyagers to set the antenna towards Earth to be able to uphold contact.
When launching the Voyagers greetings were included from us earthlings to any form of life that would get in contact with the spacecraft. It was samples of natural sounds, pictures and spoken greetings in fifty-five languages.
There is no question that there are other life in the Universe, but if they find a Voyager the chance that our greetings would mean anything to them would be minimal. Considered that our solar system is 4.6 billion years, other life forms might be 10 million years behind us in development and will not have any use for the package inside and will probably just try to eat it.
If they are 10 million years ahead of us they have most likely mapped up our planet better than we have, with better pictures and even sounds from Earth, than we have included in the probes.
There are no new unmanned spacecrafts planned for further exploration of our solar system at the moment, the focus is on setting up space habitat, like Starbright on the Moon and the first manned Mars mission expected in year 2031.
Even though Voyager 1 has been on the road for some time, it will take another 40,000 years before it encounters another star and will then do it by passing by at a distance of “only” 1.6 light years.
Argument: NASA estimates that the electric power needed for the Voyager probes to operate will last until year 2020.
