Voyager 2, a pioneer in outer photo voltaic system exploration, left Earth for interstellar area 49 years in the past, on August 20, 1977.
The twin of Voyager 1, which left Earth just a few weeks after, is the one spacecraft to go to all 4 of the photo voltaic system’s outer gasoline giants — Jupiter, Saturn, Uranus, and Neptune.
The Voyager probes had been initially despatched on a four-year mission to tour the photo voltaic system, however they exceeded expectations and are nonetheless going practically half a century later. That makes them NASA’s longest-lived mission, costing the company greater than $865 million.
The 2 probes have had their justifiable share of interstellar road bumps, which have solely been exacerbated because the probes age. In 2022, Voyager 1 began sending garbled knowledge from outdoors the photo voltaic system. NASA in the end found out that considered one of its computer systems had gone lifeless years earlier.
Voyager 2 fell into limbo in 2023, dropping contact with NASA after somebody despatched a unsuitable command. The company detected a faint signal from Voyager days later after blasting a “shout” throughout the cosmos to get the probe to level its antennae again to Earth and resume communication.
Come November 2026, Voyager 1 will probably be 16 billion miles — or one light-day — away from Earth. Voyager 2, in the meantime, will probably be greater than 13.2 billion miles from Earth, touring by way of interstellar area — the area between stars — at 34,000 mph relative to the Solar.
Whereas each probes are dropping about 4 watts of energy annually, NASA continues to make efforts to maintain them exploring.
In August, the company introduced it substituted some gadgets on Voyager 2 with “lower-power options whereas making certain the spacecraft stays heat sufficient to function.” This, it mentioned, ought to hold the probe’s instruments running for a minimum of one other yr. NASA plans to make the identical change for Voyager 1.
To rejoice Voyager 2’s forty ninth birthday, listed below are 23 images that present its historical past and what each probes have seen among the many cosmos.

The Voyager mission included two probes — Voyager 1 and Voyager 2 — which NASA launched in 1977 inside a couple of weeks of one another. Voyager 1 launched on September 5, 1977.
NASA took benefit of a uncommon planet alignment to turbocharge the journeys into area. Voyager 1 overtook its twin shortly after launch, due to a sooner flight path.
The Voyager probes carry 11 totally different scientific devices to review planetary our bodies, magnetic fields, and particles.

The Voyager probes had been designed to go to Jupiter and Saturn.

Voyager 2’s mission noticed all 4 gasoline giants.
That is what Voyager 1 noticed on its method to Jupiter.

Voyager 1 and Voyager 2 reached Jupiter in 1979.
As they flew by the planet, they took about 50,000 photos of Jupiter. These blew away scientists, as the standard of the photographs was a lot better than these taken from Earth, according to NASA.
These snaps taught scientists necessary details concerning the planet’s environment, magnetic forces, and geology that might have been troublesome to decipher in any other case.
The probes found two new moons orbiting Jupiter: Thebe and Metis.

Jupiter has over 100 identified moons; its principal 4 are Ganymede, Io, Europa, and Callisto.
Additionally they noticed a skinny ring round Jupiter.

Io is essentially the most volcanically energetic physique within the photo voltaic system.
Subsequent cease: Saturn.

In 1980 and 1981, the probes reached Saturn. The flyby gave scientists unprecedented perception into the planet’s ring construction, environment, and moons.
Voyager snapped Saturn’s rings in additional element than ever earlier than.

Pictures confirmed secrets and techniques that Enceladus, the sixth-biggest of Saturn’s practically 300 moons, needed to provide.

By 1986, Voyager 2 had made it to Uranus.

By 1986, Voyager 1 had completed its grand tour of the photo voltaic system and flew out towards interstellar area. However Voyager 2 saved on exploring our nearest planets, passing 50,600 miles away from Uranus in January 1986.
Voyager 2 discovered two extra rings around Uranus, revealing the planet had a minimum of 11, not 9.
Voyager 2 additionally noticed 10 beforehand unseen moons round Uranus.

Voyager 2 was the primary spacecraft to look at Neptune from an in depth distance.

In 1989, 12 years after its launch, Voyager 2 handed inside 3,000 miles of Neptune.
Voyager 2 was the primary spacecraft to cross by Neptune.

As its parting present, Voyager 2 took this lovely image of sunshine grazing Neptune’s south pole.

Because it would not come throughout one other planet on its ongoing journey, NASA switched off its cameras after its flyby of Neptune to preserve power for different devices.
Voyager 1 had one final trick up its sleeve.

As its final photographic hurrah in 1990, Voyager 1 took 60 pictures of the photo voltaic system from 4 billion miles away.
It gave us the Earth’s furthest selfie, dubbed the “pale blue dot.”
This stays the longest-range selfie: a portrait of the Earth taken by a human-made probe from 4 billion miles away.
After this image, NASA switched off Voyager 1’s cameras to save lots of power. NASA could switch the probes’ cameras back on, however it’s not a precedence for the mission.
Past the photo voltaic system

Although the probes are now not sending photos, they proceed to ship essential details about area.
In 2012, Voyager 1 became the first human-made instrument to cross into interstellar space by crossing the boundary between our photo voltaic system and the remainder of the universe, referred to as the heliopause.
Voyager 2 was second, crossing that threshold in 2018. The probe revealed that there was one more layer outside our heliosphere.
The probes hold sending again measurements from interstellar space, like weird hums possible coming from vibrations within the electrically charged gasoline between stars.
Even after their devices are switched off, the probes’ mission continues.

Even in spite of everything their devices turn out to be quiet, their mission will stick with it.
As they drift off, they are going to nonetheless be carrying a golden record that carries essential details about humanity. If clever extraterrestrial life exists, they might use that data to achieve out to us.
This text was initially revealed on June 6, 2022, and is being up to date with the most recent developments about Voyager 1 and a couple of. It was final up to date in August 2026.
