Satellites need to reach a specific speed, known as escape velocity, to overcome Earth's gravitational pull and enter orbit or travel into space. This speed, approximately 11.2 kilometers per second (about 25,000 miles per hour), allows them to break free from the gravitational attraction without falling back to Earth. Achieving this speed ensures that the satellite can maintain a stable trajectory and avoid being pulled back by gravity. If a satellite doesn't reach this speed, it will not be able to escape Earth's atmosphere and will eventually descend back to the surface.

What causes evaporation of Earths waters to occur?
The cause of evaporation is the continuous movement of molecules at the surface of a liquid; gaining more energy they can escape in the air. Temperature favors this process.
What is an opening in the earths crust from which volcanic materials pass through to the earths surface?
An opening in the Earth's crust from which volcanic materials, such as lava, ash, and gases, escape to the surface is called a volcano. This structure forms when magma from beneath the Earth's surface rises through cracks or fissures in the crust. When pressure builds up, it can lead to eruptions, releasing volcanic materials into the atmosphere and onto the ground. Volcanic activity can create various landforms, including mountains and islands.
What is the name of magma escape onto earth surface?
Lava.
Which of these are fissures through which water and water vapor escape from the Earth's surface?
Fumaroles, hot springs, and geysers are fissures through which water and water vapor escape from the Earth's surface. These geological features are commonly associated with areas of volcanic activity where magma heats underground water, causing it to rise and escape through the fissures.
Why does molten rock escape from under the earths surface in certain places?
Molten rock, or magma, escapes from beneath the Earth's surface through volcanic eruptions due to the build-up of pressure from the movement of tectonic plates. This pressure can push the magma upwards through cracks or weaknesses in the Earth's crust, resulting in volcanic activity.
Which of these are fissures through which water and water vapor escape from the Earths surface?
Fumaroles are fissures through which water and water vapor escape from the Earth's surface.
You say that the escape velocity is the one required to escape the earth's gravitational speed then we say the satellites stay in orbits because of the earth's gravitational speed how does that ha?
Satellites are traveling at less than escape velocity. (roughly, orbital velocity is about 7 tenths of escape).
Can the shuttle escape the earths atmosphere?
No it can't.
Difference between probes and satellites regarding orbital and escape velocity?
Probes are unmanned spacecraft that can be sent to explore celestial bodies within our solar system, typically requiring lower orbital and escape velocities compared to satellites. Satellites are objects that orbit a planet or celestial body, including artificial satellites launched into orbit around Earth. Satellites often require higher orbital and escape velocities due to their continuous or prolonged presence in orbit.
Can Satellites escape gravity?
no. They are carried in a rocket of some description, then released
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.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
The minimum initial speed for a projectile to escape Earth's gravitational pull (escape velocity) is about 11.2 km/s. This speed is independent of the mass of the projectile and is based on the balance between the projectile's kinetic energy and gravitational potential energy. Any speed greater than the escape velocity will allow the projectile to escape Earth's gravitational pull.
What causes evaporation of Earths waters to occur?
The cause of evaporation is the continuous movement of molecules at the surface of a liquid; gaining more energy they can escape in the air. Temperature favors this process.
What Crack in the earths crust where volcanic material escape?
A volcanic vent or fissure is a crack in the Earth's crust where volcanic material such as lava, gases, and ash can escape to the surface. These vents can form as a result of tectonic activity along plate boundaries or within volcanic regions.
What is an opening in the earths crust from which volcanic materials pass through to the earths surface?

What is the action of the spacecraft leaving the earth called?
escape velocity if its leaving earths gravity
Can a Boeing 747 fly into a black hole at the edge of your universe?
No. It cannot escape the Earths gravity.
