The earth's escape velocity, which is the speed necessary to overcome gravity and achieve either orbit or escape, is about 25,000 miles per hour (or about 7 miles per second). From a physics standpoint, it's the speed at which a rocket's kinetic energy plus its gravitational potential energy is zero. Every celestial body has a different escape velocity, depending upon its mass.

Why does the space shuttle have high speed in the atmosphere?

The shuttle uses the atmosphere to slow itself down from orbital speed.


Why is there a window for the space shuttle's to exit the atmosphere?

The window for the space shuttle to exit the atmosphere is crucial because it allows for a safe trajectory to reach low Earth orbit without excessive heat buildup from atmospheric friction. Exiting the atmosphere at the right angle and speed prevents the spacecraft from burning up or experiencing excessive G-forces during the ascent.


How long does it take a rocket at average speed to escape earths atmosphere?

It takes around 8 minutes for a rocket to reach space and escape Earth's atmosphere. This can vary slightly depending on the specific rocket and its speed.


What speed is needed to exit the earths atmosphere?

Any limit (if it exists, other than the speed of light) is very high.Meteors can hit the atmosphere at 71 km/s (44 miles per second). I don't know of anything faster than that, so I guess that is the fastest.44 mi/sec is 15000 mph, mach 24the speed of light is 299 792 458 m / s or 670 616 629 MPHthe Large Hadron Collider has achieved a speed of 299 792 455 m / s or670 616 622 MPHso the Large Hadron Collider can make particles go 7 MPH slower than the speed of light


How fast does a space shuttle reenter the earths atmosphere?

A space shuttle reenters the Earth's atmosphere at a speed of around 17,500 miles per hour. The high speed generates intense heat, which is why the shuttle needs heat shields to protect it during reentry. The spacecraft gradually slows down as it descends through the atmosphere.

Why is the surface wind speed and upper atmosphere wind speed over Hawaii different?

Surface wind speed is slower because there is friction to slow it down, whereas upper atmosphere wind speed is unobstructed.


Why do objects disintegrate upon entry into Earth's atmosphere but not upon exit?

The key factor is not whether they're entering or exiting, but the speed they're travelling. The escape velocity for reaching Earth orbit is some 11.2 km/s, but vehicles leaving Earth will typically reach that speed only after they've already left the upper layers of the atmosphere. Vehicles enteringthe atmosphere, however, will not have the benefit of huge engines with which to slow their approach to subsonic speeds, and will rely on atmospheric friction to do that for them. Meaning they will hit atmosphere at speeds in excess of 10 km/s.

As you enter the de-acceleration lane or the exit ramp slow down and?

Be sure to reduce your speed gradually, signaling your intent to exit. Check your surroundings for other vehicles and safely merge into the exit ramp or de-acceleration lane at a slower speed than the main roadway. Maintain a safe following distance from other vehicles as you prepare to exit or merge.
