The speed of spacecraft depends on the distance from point A to point B.
When the distance of a planet is more from the earth, the speed is recorded through the radio waves sent from the earth’s space center.
As these radio waves have the same speed as that of light, when these waves strike the spacecraft and are reflected back to the earth, the comparison of the speeds can give out the resultant speed of the spacecraft.
The application of Doppler’s effect is also useful in determining the speed of a spacecraft.
