It must overcome Earth's gravity.
The gravitational pull between earth and the spacecraft will become insignificant.
Assuming by spaceship you mean a spacecraft that leaves Earth carrying people. This excludes unmanned spacecraft and space stations. Soviet/Russian -- Vostok & Soyuz US -- Mercury, Gemini, Apollo, Shuttle The Lunar Module was a spacecraft the carried men, but it did not leave Earth carrying people.
It never left. The spacecraft had an electrical fire during testing, killing the three astronauts aboard.
It prevents the spacecraft from being launched as gravity causes it to be attracted towards earth.
The Apollo spacecraft traveled at a maximum speed of 24,000 mph. To overcome the Earth's gravitational pull, one must travel at or above its escape velocity which is 24,000 mph.
The speed that a spacecraft must reach to leave Earth forever is 25,000 miles per hour. This is called "escape velocity", and this is the initial velocity required to leave the Earth behind completely. However, the concept of "escape velocity" is fundamentally flawed, being based on the concept of a shell being fired from a giant cannon. A rocket with enough fuel may leave the Earth behind at any speed desired. The required velocity to attain orbit depends on the altitude of the orbit; curiously, lower orbits require more speed, while higher orbits require less speed - but more fuel to get there! At the altitude of the ISS, an object must be going at about 18,000 MPH to be in a circular orbit.

No spacecraft from Earth has ever landed on Neptune.
a slower speed will not overcome the gravitational pull of the Earth. It would fall back to Earth.
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft.
the Friendship 7 spacecraft
It prevents the spacecraft from being launched as gravity causes it to be attracted towards earth.
When a spacecraft goes into space its speed increases dramatically once it leave the earths atmosphere. When it is returning to earth, it hits the atmosphere at a faster rate than it was traveling when it left. The friction of the atmosphere against the craft, heats it up.
No.
