escape velocity if its leaving earths gravity
A spacecraft without people on board is called an unmanned spacecraft or a robotic spacecraft. These types of spacecraft are operated remotely from Earth or operate autonomously.
John Glenn's spacecraft was called Friendship 7
A space craft that orbits the earth is called a satellite.
The Mariner Ten and the Messenger
To overcome gravity when leaving Earth, a spacecraft must reach a high enough speed to break free from Earth's gravitational pull. This is achieved by launching the spacecraft at a high velocity using powerful rockets. Once the spacecraft reaches escape velocity, it can overcome Earth's gravity and continue its journey into space.
The first spacecraft to land on the moon was called the Eagle, after the novel of Jules Verne called From the earth to the moon.
The first spacecraft to orbit the Earth was called Sputnik 1, launched by the Soviet Union on October 4, 1957.
A spacecraft or a rocket.
The first spacecraft carrying a human to land safely was Vostok 1 carrying cosmonaut Yuri Gagarin.
The gravitational pull between earth and the spacecraft will become insignificant.
A spacecraft that is controlled from Earth is typically referred to as a teleoperated spacecraft. This means that it is being controlled by operators on Earth rather than operating autonomously.
A spacecraft travelling at approximately 25,000 miles per hour can escape Earth's orbit. This speed is known as the escape velocity and allows the spacecraft to overcome the gravitational pull of the Earth.
