How long does it take to reach the ISS?

6 hours to 3 days

Even though most rockets can reach the height of the ISS in just a few minutes, matching its orbit and speed is a whole other story. This means that the time it takes to get to the ISS can vary from 6 hours to 3 days, depending on the rocket’s characteristics, launching point on earth, and mission profile.
