Rocket ships typically travel at tens of thousands of miles per hour, and the fastest space probes reach hundreds of thousands of miles per hour.

Quick Scoop: How fast does a rocket ship go?

Think of “rocket ship speed” in a few stages of flight.

  • To get into low Earth orbit, a rocket needs about 7.8 km/s – roughly 28,000 km/h or 17,500 mph.
  • This is the kind of speed reached by rockets like Falcon 9 when they’re placing satellites or spacecraft into orbit.
  • To fully escape Earth’s gravity and head into deep space, you need around 11.2 km/s – about 40,000 km/h or 25,000 mph, known as escape velocity.

Once a spacecraft is in space and doing gravity‑assist maneuvers, it can go much faster relative to planets or the Sun.

  • NASA’s Juno spacecraft reached about 365,000 km/h (around 165,000 mph) as it approached Jupiter, one of the fastest human‑made speeds recorded.
  • Other missions using powerful rockets and gravity assists commonly cruise around 39,000 km/h (about 24,000 mph) between planets.

So, “how fast does a rocket ship go?”

  • Around 28,000 km/h (17,500 mph) to orbit Earth.
  • Around 40,000 km/h (25,000 mph) or more to escape Earth.
  • Up to a few hundred thousand km/h for the very fastest space probes in deep space.
