What was the first US spaceship to orbit the earth?
voyager Explorer 1 was the first US satellite to orbit the earth. It was proceeded by two Soviet Sputnik satellites.
How do satellites move?
A Satellite movement behaves in two ways. Its orbit may be defined either as "geosynchronous" or "geostationary". Geosynchronous satellites move together with the Earth's own orbit, so it revolves in the same way as the earth is. Geostationary satellites remain statically in place for a certain coordinate...
What two forces keep the moon and all other satellites in orbit around earth?
Gravity and Inertia
What was the purpose of Sally ride's mission?
Her purpose was to put two satellites from Canada and Indonesia into orbit around the Earth.
Why does the space shuttle track on the surface of the earth in a serpentine configuration?
That apparent course is actually more to do with the fact that the shuttle and most satellites orbit the earth at angles to both the lines of latitude and longitude. Also there is the factor that Earth is rotating as they orbit. It is a combination of the two, shown on a two-dimensional screen that gives the apparent serpentine orbit, although that is not what is actually happening.
What term is given to satellites that remain above the same point on the Earth's surface in their orbit?
There are two types of satellites that are located in a foxed spot over earth the first is reconnaissance satellites for observation of earth and usually used by the military.. The second is earth observation satellites and are intended for environmental monitoring
How satellites stay in orbit?
The reason that satellites stay in orbit around Earth is because of two factors. Velocity and the gravitational pull between the satellite and the Earth.
Cost of satellite?
There are two types of satellites, Genuine Satellites, which are any body that orbit a planet. For instance, our moon is a satellite of the earth, and there are artificial satellites which are man made objects that orbit a planet. These range from few tens of millions, to few hundred millions.
Do all satellites orbit the same direction?
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.

What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
How many times does a GPS satellite orbit the earth in a week?
The GPS satellites are not in geo-stationary orbit, but instead orbit twice every time the Earth rotates once. This means that for any observer the satellites appear to orbit once overhead each day. Such an arrangement gives better coverage. It is also clever in the sense that the motion of any GPS satellite will repeat itself each day. The GPS constellation of 24 satellites are arranged in six different orbital planes, each inclined 55 degrees to the equator. To obtain exactly two orbits per day, the satellites are placed at an altitude of 20,200km!!!
Does the earth have two satellites or Mars?
Mars has two natural satellites. Earth has one.
What are the name of the two moons that orbit the mars?
The two natural satellites that orbit Mars are Phobos and Deimos.
