Unbelievable Simulation: Voyager 1's Mind-Blowing Speed in Real-World Context
The Voyager 1 satellite is one of the fastest human-made objects, outpacing everything else created on Earth by a significant margin. But it's challenging to comprehend this speed in everyday terms.
It's also the most distant human-made object from our planet. As of this writing, it's traveling through the galaxy approximately 15 billion miles away, moving at a velocity of 38,026.79 mph (17.0 km/second).
The Airplane Mode YouTube channel has crafted a simulation of Voyager 1's speed if it were on Earth, and, as seen in the clip above, it's incredibly fast. This simulation highlights the sheer magnitude of Voyager 1's speed, making it difficult to fathom.
Voyager 1 is nearly 50 years old, and its speed is truly out of this world. Launched in 1977, it's one of the oldest active space probes. Its mission was to study the outer Solar System, and so far, it's been a remarkable success.
Voyager 1 has already flown by Jupiter and Saturn, and it even passed by Saturn's largest moon, Titan. NASA is uncertain about the probe's longevity, but they do know that after 2036, it will likely be out of range of the Deep Space Network, making communication with it challenging.
The Reason Behind NASA's Double Launch in 1977
In the 1960s, during the peak of the Space Race, NASA recognized a unique opportunity. They realized that the 1970s would present a rare chance to launch two space probes capable of passing by Jupiter, Saturn, Uranus, and Neptune in a single mission. This phenomenon, known as Syzygy, occurs when three or more celestial bodies align in a gravitational system.
NASA seized this once-in-a-lifetime opportunity by launching two twin space probes, Voyager 1 and Voyager 2. Interestingly, Voyager 1 was launched after Voyager 2, and it has traveled much further. As of February 2026, Voyager 1 is approximately 2.5 billion miles farther from Earth than Voyager 2.
