Soyuz Rendezvous


This docking was fully automated, giving the cosmonauts a chance to film it. The ship seems to be moving very slowly towards the station. In reality, however, both objects are flying with the ‘first cosmic velocity’ almost 28,000 km/h, or 8 km per second! That’s 200 times faster than your car on a highway. And for the ISS it is the required minimum speed to keep it in orbit and prevent it from falling down to Earth.
