What does an orbiting shuttle that follows the curve of Earths surface as it moves at a constant speed have to be?

Mainly, it has to:
(1) Move at a sufficiently high speed. Near the Earth's surface, that would be about 7.9 kilometers per second (7900 meters per second). You can multiply the meters per second by 3.6 if you prefer it in kilometers/hour.
(2) Be sufficiently far from Earth, to avoid air resistance. A height somewhere between 100 and 200 kilometers is required, for a relatively stable orbit.
Comment: I think "in a circular orbit" is what the question is looking for as the answer.

Why do astronauts orbiting the earth experience weightlessness even though they are still within the earth's gravitational field?
When something is orbiting the Earth, it is actually falling toward the Earth. But because a space shuttle has such a great velocity (speed w/ direction) it misses hitting the Earth's surface. Image you throw a baseball. The baseball follows the path of a curve called a parabola, but the parabola is actually part of an eclipse (elongated circle). Now image if you threw the baseball so hard that when it fell toward the Earth, it actually missed the "edge" of the Earth following the path of the eclipse around the Earth. That baseball would then be launched into orbit. (Of course you would have to throw this baseball at a speed of 11 km/s).
What is Apollo 11 lunar module?
A lunar module is a small craft that is used as an orbiting spacecraft and to travel between the moon's surface. It was the first man-made vehicle that was able to leave outside the earth's atmosphere.
Is the Messenger Spacecraft a Probe or Rover?
The Mercury Messenger is an orbiting space probe observing the planet Mercury. We generally reserve the word "rover" for a tracked or wheeled vehicle which moves around on the surface, and we haven't tried to do that yet.
If a satellite orbiting just above the surface of the Earth orbits in about 1.5 hours then at about how many Earth radii from the Earth's center must a satellite orbit to have a period of 24 hours?
You can use Kepler's Third Law to calculate this.
Are the voltages across all branches of a parallel circuit the same?
In a parallel circuit, all the branches are joined together at their start and again at their end by a conductor (usually wire).Now, the surface of a conductor (ideally) is an equipotential surface. That is, any point of its surface has the same electric potential.And since the voltage across each branch equals the difference in electric potentials between its start and its end, and these potentials are the same for every branch, it follows that the voltages across each branch must be equal to each other.
Why would water form nearly spherical drops onboard the space shuttle or an orbiting space station?
Its surface tension hold it in a logical shape (why is a bubble spherical?)
How does the force of gravity on an astronaut orbiting in the space shuttle compare with the force of gravity on the same astronaut when she is standing on the earth s surface?
Gravity is proportional to the mass and inversely proportional to the square of the distance of the centre of the body or bodies.As the shuttle orbits at a comparatively low altitude and the mass remains constant the force diminishes only slightly. Being in free-fall does not mean there is no gravity.

What is the acceleration due to gravity between the Earth and a space shuttle where mass of space shuttle equals 25000kg when the space shuttle is orbiting 450km above the surface of the Earth?
its handy to ignore the shuttle weight in these calcs, unless you need immense accuracy, but its included anyway.G = newtons gravitational constant = 6.672 * 10 ^-11 ( m^3 / kg^-1 / s^-2)m1 = mass earth = 5.974 * 10 ^24 (kg)m2 = mass shuttle = 25 000 (kg)r = orbital radius from earth centre to shuttle = 6 371 + 450 = 6 821 km= 6 821 000 metresacceleration due to gravity= (G *( m1+m2 ))/ r^2= 8.5669 ( m/s)/s
