What Will Happen To Voyager 1 After Earth Vanishes?

Voyager 1 is the most distant spacecraft humanity has ever launched. Sent into space by NASA in 1977, it is now more than 23 billion kilometres from Earth, travelling through interstellar space beyond the outer edge of our solar system. It weighs 722 kilograms, runs on nuclear decay, and somehow, after nearly 50 years, it is still sending signals back to Earth. On August 25th, 2012, Voyager 1 became the first human-made object to cross into interstellar space, passing beyond the heliopause, the mysterious boundary where the Sun’s influence fades and the galaxy begins. Since then, Voyager 1 has detected a faint plasma hum in the interstellar medium, measured electron densities more than 161 astronomical units from the Sun, and revealed that the edge of the solar system is not a clean wall, but a strange, shifting, porous frontier that scientists are still trying to understand. This documentary follows Voyager 1 from launch in 1977 to the end of the universe itself. From the volcanic eruptions on Io discovered by engineer Linda Morabito in a routine navigation image, to the cracked ice of Europa hiding an ocean larger than all of Earth's combined, to Carl Sagan's battle to turn the cameras back one final time and photograph the Earth as a pale blue dot we cover the full story. Then we follow Voyager beyond the heliopause, into interstellar space, and forward through 40,000 years to its closest approach to another star. Then billions of years further: the death of the sun, the Andromeda collision, the end of the stelliferous era, proton decay, and the heat death of the universe. Strapped to the side of the spacecraft is the Golden Record a gold-plated copper disc carrying 90 minutes of music, greetings in 55 languages, 115 images, and the brainwaves of Ann Druyan recorded the day after she fell in love with Carl Sagan. It was never expected to be found. It was made anyway. If you're drawn to the deep questions — where we are, what we are, and what it means that we reached subscribe. We're just getting started. This documentary covers the Voyager 1 mission from launch to interstellar space, the Golden Record, the Pale Blue Dot, planetary discoveries at Jupiter and Saturn, the crossing of the heliopause, the long-term trajectory of the spacecraft through the galaxy, and the ultimate fate of matter and energy in the far future of the universe.
