Why must a spacecraft reach escape velocity to be able to go to space?

A rocket needs to travel at 7 miles-per-second or about 25,000-miles-per-hour to leave the pull of earth's gravitational force, and reach outer space. This speed is known as escape velocity.

Is capable of NASA space shuttle reach escape velocity from the Earth?
...No.
What speed does a rocket have to reach to get into space?
(Escape velocity) at least 7 miles ber second. Close-Orbital velocity is about 5 miles per second.
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
How does an astronaut travel up into space?
Astronauts in their spacecraft (such as the Space Shuttle) are lifted into space by huge rockets which accelerate the craft to "escape velocity" (about 25,000 mph). This puts the craft into orbit around the Earth, its forward velocity balancing the continuous pull of gravity. When they are ready to return to Earth, they use rockets to slow down, and gravity pulls them back out of orbit.
The velocity a rocket must reach to establish an orbit in space is?
The velocity of rocket must reach 16x than the gravitational force of Earth to establish an orbit in space.
How do you travel unto space?
You need a spacecraft that will exceed escape velocity.
Why must spacecraft reach escape velocity to be able to go to space?
a slower speed will not overcome the gravitational pull of the Earth. It would fall back to Earth.
Is capable of NASA space shuttle reach escape velocity from the Earth?
...No.
Have any MANNED vehicles reached 'escape velocity' - If so what were they?
Yes, several manned vehicles have reached escape velocity, which is about 25,000 miles per hour. The Apollo spacecraft used during the moon missions reached escape velocity en route to the moon. Also, the Space Shuttle reached escape velocity when it orbited the Earth or traveled to the International Space Station.

What must be done to put a rocket into space outside of an orbit of the earth?
It has to reach escape velocity which on Earth is 11.2 Km per second
Why doesn't NASA Launch a Space Probe Perpendicular to the plane of the ecliptic?
Because the solar escape velocity from Earth is 41 km/s, and we are barely able to reach those speeds, even with our fastest spacecraft. Parallel to the ecliptic, we can "cheat" by getting gravity assists from other planets.
What is the velocity a rocket needs to reeach to orbit in space called?
Escape velocity.
How many hours does it take from earth to space?
The escape velocity fo spacecraft to reach orbit is approximately 7 miles per second (11.3 km/sec). At that velocity, a rocket would need just 14 seconds to reach space! But the acceleration is necessarily slow, and rockets typically require 15 to 20 minutes to boost their payloads into low earth orbit (typically 80 to 100 miles up), where they coast until insertion into higher orbits.
Why should a spacecraft be space-tight?
Any suddenly opening appearing in the skin of the spacecraft would allow the atmosphere inside the craft to escape out into space - causing decompression.
How do sattalites get up in to space?
escape velocity of satellite is greater
