A Viral Simulation Reveals Just How Terrifyingly Fast the Space Station Moves

A Speed That Defies Comprehension

Most of us have glanced up at the night sky and spotted the International Space Station — a steady, bright dot gliding silently overhead. It looks almost peaceful. But a viral simulation created using Microsoft Flight Simulator 2020 has shattered that calm impression, leaving viewers across the internet genuinely stunned by what the ISS's speed actually looks like up close.

YouTuber Airplane Mode used Microsoft Flight Simulator 2020 to give viewers an idea of just how fast the ISS really moves from ground level. The animation imagines what it would look like to see the ISS cruising at 10,000 feet above the ground — a dramatic drop from its real orbital altitude — and the result is jaw-dropping.

The Numbers Behind the Madness

The ISS can travel at 17,100 mph, and its orbital period is 92.9 minutes — meaning it goes all the way around the globe every hour and a half or so. To put that in everyday terms, this is around 29 times faster than the speed of an average commercial airplane.

The video, made by speeding up footage created using Microsoft Flight Simulator 2020, helpfully compares the velocity to Mach 1, the speed of sound — and it shows the ISS flying over forests, mountain ranges, and cities like New York in mere seconds. The ISS passes over towns and cities in seconds, sometimes even milliseconds. For context, the Lockheed SR-71 Blackbird — long considered one of the fastest aircraft ever built — can travel at 2,190 mph, or Mach 3.3. The ISS laps it nearly eight times over.

You might think it doesn't make sense for the ISS to travel at such a staggering speed, but it's necessary as a consequence of its distance from Earth. The further an object gets from our planet, the more distance it has to travel to complete a full rotation — so the faster it has to go to "keep up" with the speed of Earth.

Why It's So Hard to Grasp Without a Simulation

From video footage recorded in space, it's not possible to really tell just how fast the ISS is going as it hurtles around the planet. That's exactly what makes this simulation so effective — it anchors an abstract number to something the human brain can actually process. Static landscape shots barely give you a chance to spot the ISS speeding past, as it's literally here and gone in the blink of an eye, whereas from the perspective of the space station itself you can see how it flies across the surface of the Earth in no time.

Viewers flooded the comments with reactions ranging from awe to existential amazement. "This really puts into perspective how slow sound actually is, this is crazy stuff!" wrote one commenter. Another added: "I think it's crazy that we as humans made an object go that fast. I bet Newton would be pretty shocked to hear we actually went fast enough to orbit Earth like he theorized back when the fastest vehicles were sailing ships."

An Engineering Marvel Racing Toward Retirement

The International Space Station is an engineering marvel, with its first launch nearly 30 years ago, and it is set to be de-orbited by the end of 2030. Once its mission is over, it will be disposed of by gradually reducing its orbit until it is pulled down to Earth, meeting its end in the South Pacific Ocean Uninhabited Area — otherwise known as Point Nemo, the most remote place on the planet.

As the ISS enters its final years of operation, simulations like this one serve as a powerful reminder of what humanity has achieved. A football-field-sized laboratory hurtling around the planet at nearly five miles per second — invisible to most of us, yet always overhead. Sometimes it takes a viral video to make the extraordinary feel real.
