Earth's orbital speed averages about 30 km/s (108,000 km/h; 67,000 mph), which is fast enough to cover the planet's diameter in seven minutes and the distance to the Moon in four hours.
To leave Earth's orbit, the spacecraft has to fly faster than Earth's escape velocity (the velocity required to escape the gravitational influence of Earth on the spacecraft). Prior to the third stage firing, the spacecraft is only going about 19,500 mph and it is stuck orbiting Earth.o leave Earth's orbit, the spacecraft has to fly faster than Earth's escape velocity (the velocity required to escape the gravitational influence of Earth on the spacecraft).
