Why does a rocket have to go 25,000 mph (about 40,000 kilometers per hour) to escape Earth? – Bo H., age 10, Durham, ... Scientists call that speed the escape velocity.

Escape velocity: To escape Earth’s gravity, you have to travel 25,000 miles (40,200 km) per hour. Other information: The highest point on Earth’s surface is Mount Everest on the border of ...

But to travel from low-Earth orbit (LEO) to farther orbits—or even the Moon—requires a different kind of ion thruster capable of achieving escape velocity and orbital capture maneuvers.

To completely escape the pull of the Earth permanently, however, does take a little bit of work: you have to reach escape velocity, which is a speed of 25,000 miles per hour. To give a sense of the ...

The Soviet spacecraft Kosmos-482 was launched in 1972 on a mission to Venus. But due to a rocket malfunction, it's been hurtling back towards Earth in an elliptical orbit for the past 53 years.
