  • Voyager 1 Speed: Approximately 38,027 miles per hour relative to the sun
  • Voyager 2 Speed: 34,391 miles per hour relative to the sun
  • Communication Delay: Light from the sun takes over 23 hours to reach Voyager 1; commands take nearly a full day for confirmation
  • Key Discovery Areas: Magnetic fields, cosmic rays, plasma density, and the boundary between our solar system and the galaxy

  • Golden Record: Both carry gold-plated phonograph records with sounds, images, music, and greetings from Earth

Are you curious about humanity’s most distant explorers? Right now, two spacecraft are traveling deeper into space than any human-made object ever has. They’re sending back data from a place we were never meant to reach. In this guide, you’ll discover where Voyager 1 and Voyager 2 are today, what they’ve learned along the way, and why their journey still matters for all of us.

The Current Locations of Two Legendary Spacecraft

Voyager 1 and Voyager 2 have traveled farther than any spacecraft before them. As of 2025, Voyager 1 sits approximately 169.9 astronomical units (AU) from Earth—that’s about 15.8 billion miles away. Meanwhile, Voyager 2 trails behind at roughly 141.5 AU from Earth, or about 13.1 billion miles.

Here’s the thing: These distances are almost impossible to grasp. Light from the sun takes over 23 hours to reach Voyager 1. When scientists send a command to the spacecraft, they must wait almost a full day just to receive confirmation that it arrived.

Both spacecraft have already crossed into interstellar space—the region between stars. Voyager 1 made this historic crossing in August 2012, while Voyager 2 followed six years later in November 2018. They’re no longer exploring our solar system. They’re now humanity’s ambassadors to the cosmos itself.

Did you know? Voyager 1 travels at approximately 38,027 miles per hour relative to the sun, while Voyager 2 moves at 34,391 miles per hour. Yet it still takes them decades to cover vast cosmic distances.

Why These 48-Year-Old Missions Still Matter

You might think that after nearly five decades, these spacecraft would be obsolete. But here’s what’s remarkable: Voyager 1 and Voyager 2 continue to send back groundbreaking scientific data from regions of space no one has ever explored before.

The Voyagers were originally designed for a five-year mission to visit Jupiter and Saturn. Nobody expected them to last this long. Yet through brilliant engineering and careful power management, they’re still operational and still teaching us about the universe.

These spacecraft are studying interstellar space in ways that telescopes on Earth simply cannot. They’re measuring magnetic fields, detecting cosmic rays, and analyzing the density of plasma in regions billions of miles away. The data they transmit helps scientists understand the boundary between our solar system and the rest of the galaxy.

Groundbreaking Discoveries Along the Way

The Voyager missions revolutionized our understanding of the outer solar system. Before these spacecraft flew by Jupiter and Saturn, scientists knew remarkably little about these distant worlds. Here are some of their most important findings:

First close-up photos of the outer planets: Voyager gave us the first detailed images of Jupiter, Saturn, Uranus, and Neptune. These pictures transformed how we see our solar system.

The Pale Blue Dot: In 1990, Voyager 1 turned its camera back toward Earth one final time. The resulting image showed our entire planet as a tiny, pale blue dot suspended in a sunbeam. Carl Sagan’s words about this photo became iconic: “That’s here. That’s home. That’s us.”

Volcanic moons and rings: Voyager discovered active volcanoes on Jupiter’s moon Io, revealing that moons could be far more dynamic than scientists had imagined. The mission also captured stunning images of ring systems around Jupiter, Uranus, and Neptune.

Oceans beneath ice: Voyager’s observations of Jupiter’s moon Europa and Saturn’s moon Enceladus suggested these worlds might harbor liquid water oceans beneath their icy surfaces—a discovery that sparked decades of follow-up research.

Lightning beyond Earth: Voyager 1 detected the first lightning ever observed outside our planet, occurring in Jupiter’s atmosphere. This finding expanded our understanding of planetary weather systems.

The Challenges of Keeping Ancient Spacecraft Alive

Here’s the best part: The Voyager team continues to perform engineering miracles to keep these spacecraft operational. In November 2023, Voyager 1 stopped transmitting usable data back to Earth. A memory chip had failed, and the spacecraft could receive signals but couldn’t send them back.

The team faced an enormous challenge. The original documentation explaining how these systems worked was written by hand or on typewriters decades ago. It couldn’t be easily searched or digitized. Yet through persistence and ingenuity, they solved the problem. By April 2024, Voyager 1 was transmitting data again.

This achievement reminds us why these missions matter so much. We’re not just maintaining old equipment—we’re preserving humanity’s connection to the cosmos. Every message takes nearly 24 hours to reach the spacecraft one way. The team works carefully, knowing that any mistake could be catastrophic and irreversible.

What Happens When the Power Runs Out?

The Voyager spacecraft won’t last forever. Their power sources—radioisotope thermoelectric generators—are gradually depleting. Scientists estimate the missions could continue until around 2027 when the spacecraft celebrate their 50th birthdays, though some instruments may fail sooner.

The team is already making difficult decisions. In 2024, Voyager 2 turned off its plasma-science instrument to conserve power. Voyager 1 is doing slightly better but will eventually face the same constraints. Four of the 11 instruments on each craft are still working today.

When these spacecraft finally go silent, it will mark the end of an era. Many scientists have dedicated their entire careers to the Voyager mission. Some plan to retire alongside these remarkable explorers. Their loss will be deeply felt by the scientific community and space enthusiasts worldwide.

The Message in a Bottle to the Stars

Both Voyager spacecraft carry something truly special: the Golden Record. This gold-plated phonograph record contains sounds and images from Earth—music, greetings in 55 languages, and natural sounds like wind and thunder. It’s a message to any intelligent life that might encounter these spacecraft.

The record includes music from Bach, Beethoven, and Chuck Berry. It features greetings from world leaders and ordinary people. It’s humanity’s attempt to say hello to the cosmos, just in case someone is listening.

This symbolic gesture captures the essence of the Voyager mission. These spacecraft aren’t just scientific instruments. They’re representatives of human curiosity, ambition, and our desire to explore the unknown.

Key Takeaways

  1. Voyager 1 and 2 are the most distant human-made objects, currently traveling through interstellar space at distances of 169.9 AU and 141.5 AU from Earth respectively.

  2. These spacecraft continue to send back groundbreaking data about magnetic fields, cosmic rays, and plasma in regions of space never before explored by humanity.

  3. The Voyager missions revolutionized our understanding of the outer planets, discovering everything from volcanic moons to ring systems to lightning on Jupiter.

  4. Engineering teams perform ongoing miracles to keep these 48-year-old spacecraft operational, including fixing critical failures with decades-old technology.

  5. The missions will likely end around 2027 when power sources finally deplete, marking the end of an era in space exploration.

The Voyager spacecraft represent humanity’s greatest achievements in exploration. They’ve traveled farther than we ever imagined possible, discovered wonders we never expected to find, and continue to teach us about our place in the universe. As they journey into the cosmic unknown, they carry with them our hopes, our questions, and our dreams of understanding the stars.
