Scientists call that speed the escape velocity. A rocket needs to go that fast so that the momentum propelling it away from Earth is stronger than the force of gravity pulling it back. Any slower ...

Planets of different masses have different escape velocities. Earth's escape velocity is 11.2 km/s (kilometers per second), which is more than 40,000 km/h. The escape velocity is for ballistic ...

There’s a reason why a rocket has to go so fast to escape Earth. It’s about gravity – something all of us experience every moment of every day. A SpaceX Falcon 9 rocket with its Crew Dragon capsule ...

But to travel from low-Earth orbit (LEO) to farther orbits—or even the Moon—requires a different kind of ion thruster capable ...

The probe slipped into a solar orbit between Mars and Earth. It was the first manmade object to reach escape velocity from Earth’s gravity. Research obtained from the probe included new data ...
