Yes !
John Glenn.(We're almost certain that he was the first American to orbit the earth in anything,since we can't think of any other way to do it other than in a space vehicle.)
I would call that a Space Shuttle.
Orbital times vary as a function of the height of the orbiting vehicle or object. The higher its altitude, the longer it takes to make an orbit. The ISS and space shuttle are in low earth orbit and take approximately ninety minutes to complete one orbit.
The earth needs to be at a point in its orbit from which the Hohmann transfer orbit between earth and the orbit of Saturnrequiring the least launch energy terminates at the point where Saturn will be when the vehicle gets there.You might want to read that again, slowly. That's as plain as I know how to say it.
A high orbit. The effect of gravity gets less as you get further away from the Earth and so you'd need less speed to keep up.
An earth orbit that is lower to earth then both a medium and high earth orbit.
The planets do not orbit the Earth, they orbit the sun.

Never. The space shuttle was a Low Earth Orbit vehicle; it could never have reached the Moon.
