How many orbiters does the moon have?

With the completion of the five Lunar Orbiter missions, 99% of the Moon was photographed with resolution of 60 meters or better. This was 10 times better resolution than the best observations from Earth.

Who was the first orbiter around Earth?

In April 1961, Gagarin was the first man in space, and his spacecraft Vostok 1 made a full orbit before returning to Earth. Less than one month later, Shepard was launched into space aboard Freedom 7 on a suborbital flight. In July, Grissom made another brief suborbital flight aboard Liberty Bell 7.

What do orbiters do?

An orbiter is a space plane that goes into orbit around the earth. It also had a complex system of secondary thrusters and maneuvering engines that allowed it to move around in orbit. The payload (cargo) bay carried up to two satellites or a whole laboratory into orbit.

How many satellites are circling the Moon?

More than 500 active satellites are bustling about up there right now. Some are transmitting radio, television, and telephone signals; others are gathering information about Earth’s atmosphere and weather; still others are helping people navigate down here; and the rest are conducting space research.
