1 + 2

NASA’s Voyager 1 and 2 launched in 1977 to explore the giant planets. They now study interstellar space, beyond the bubble of particles flowing from the Sun. Follow what they saw and how their journeys continue.

ONE DESIGN · TWO TRAJECTORIES

Together at departure. Separate beyond Saturn.

Voyager 1 took the faster path past Jupiter and Saturn. Voyager 2 continued through the only close reconnaissance ever made of Uranus and Neptune. Their routes now leave the Sun in different directions.

1979—1990 · THROUGH THEIR CAMERAS

The worlds they brought us close to.

The photographs below were made by the Voyager spacecraft. Follow the journey in the order the worlds came into view; each image opens its NASA record.

Jupiter

A storm larger than Earth, seen in motion and detail.

Voyager 1's colour-filter images revealed the intricate clouds around the Great Red Spot. The encounters also exposed active volcanoes on Io and a faint ring around Jupiter.

Saturn

The rings became a world of their own.

The two flybys exposed fine ring structure and a family of icy moons. Voyager 1 turned toward Titan's dense orange haze; Voyager 2 kept the route to Uranus and Neptune open.

Uranus

An unfamiliar planet turned on its side.

The only close encounter with Uranus revealed a pale atmosphere, dark rings and moons. Its almost featureless disc in visible light was itself a startling change after Jupiter and Saturn.

Neptune

Blue, storm-torn, at the edge of the tour.

Voyager 2's final planetary encounter revealed dark storms, fast winds and Triton, where it observed active plumes.

Then they looked back.

Beyond Neptune, Voyager 1 made a final family portrait of the solar system. Earth is a faint point in a scattered ray of sunlight. The cameras were switched off after this sequence; the journey continued without pictures.

THE INTERSTELLAR MISSION

The image ended. The measurement continues.

The cameras no longer observe planets. Surviving instruments measure particles, fields and plasma beyond the heliopause. As their radioisotope generators lose power, engineers progressively switch off systems to preserve the remaining science.

ENGINEERING ACROSS DECADES

Keeping Voyager operating.

Voyager’s longevity is also the record of mission teams who inherited an ageing spacecraft, studied decisions made decades earlier and found careful solutions under extraordinary constraints.

Contact restored

After the antenna shifted two degrees away from Earth, the Deep Space Network sent an interstellar ‘shout’. Full communication returned after a 37-hour round trip.

Code rebuilt around failed memory

Engineers divided affected flight-software code and relocated it across the remaining memory. Readable engineering and science data returned.

Dormant thrusters revived

A team re-examined a failure accepted in 2004 and restored roll thrusters once considered unusable, creating a vital backup.

Power preserved

A coordinated ‘Big Bang’ reconfiguration avoided another instrument shutdown in 2026 and should keep Voyager 2’s three remaining science instruments operating for at least an extra year.

THE GOLDEN RECORD

A record of Earth aboard each spacecraft.

Each Voyager carries a phonograph record selected as an account of its planet of origin.

90 minmusic from different cultures and eras

The records also contain natural sounds and printed messages. NASA describes their possible discovery as dependent on an advanced spacefaring civilisation encountering either spacecraft.

GET TO KNOW THE MISSION

Curious about Voyager 1 and 2?

What are Voyager 1 and Voyager 2?

Two NASA robotic spacecraft launched in 1977. Both explored Jupiter and Saturn; Voyager 2 continued to Uranus and Neptune before their journeys extended into interstellar space.

What does interstellar space mean here?

The region beyond the heliosphere, the bubble formed by the solar wind. Voyager 1 crossed its boundary in 2012 and Voyager 2 in 2018.

Have they left the Solar System entirely?

Not in the broad gravitational sense. They are beyond the solar-wind bubble, but have not yet reached the distant Oort Cloud, a region of icy bodies still associated with the Sun.

What do they measure now?

Their remaining instruments study the environment beyond the heliosphere, including particles, magnetic fields and plasma waves. Declining electrical power limits what the spacecraft can operate.
