Voyager 1 deep space

Voyager 1, a NASA space probe launched in 1977, is the farthest human-made object from Earth, exploring interstellar space since 2012.

About this subject

Voyager 1 is a NASA robotic space probe launched on September 5, 1977, just weeks after its twin Voyager 2. Originally designed to study Jupiter and Saturn, the mission has been extended multiple times and the spacecraft remains operational as the most distant human-made object from Earth. On August 25, 2012, Voyager 1 crossed the heliopause and entered interstellar space, becoming the first human artifact to reach this region.

During its flyby of Jupiter in 1979, Voyager 1 discovered active volcanism on the moon Io, a groundbreaking finding that reshaped understanding of moons in the solar system. At Saturn, it revealed intricate ring structures and discovered new moons including Atlas, Prometheus, and Pandora. The probe also carries the Golden Record, an audiovisual compilation of Earth's life and culture created by a committee led by Carl Sagan, intended as a message for any extraterrestrial intelligence.

Today, Voyager 1 travels about 24 billion kilometers from the Sun, sending back data on magnetic fields and cosmic particles from interstellar space. Its power comes from radioisotope thermoelectric generators, and its instruments are expected to continue operating until around 2025, when power will be insufficient. The probe has already left the solar system and continues its journey into the unknown, carrying humanity's signature.

Frequently Asked Questions

How far is Voyager 1 from Earth currently?

Voyager 1 is approximately 24 billion kilometers from Earth, traveling at about 61,000 km/h. The distance increases constantly.

What is the Golden Record on Voyager?

It is a copper phonograph record plated in gold containing sounds, music, and images of Earth, designed as a time capsule to communicate human life to potential alien civilizations.

Is Voyager 1 still sending data to Earth?

Yes, Voyager 1 still transmits scientific data via NASA's Deep Space Network, though its instruments are being gradually shut down to conserve power.
