One of the main reasons why there is a push to construct a base on the moon is because telescopic observations from the moon would be clearer due to the fact that there would be no interference from an atmosphere, as is experienced on the Earth.
AnswerMoon AnswerThe heavy mirror in a large telescope becomes distorted in a gravitational field when fixed on the earth, which would happen even on the moon with its reduced gravity. This reduces the quality of the image. Actuators placed under the mirror are used to minimise this effect in some large modern telescopes (called active optics, see reference).However, orbiting the earth in space the telescope mirror becomes weightless and these effects can be virtually eliminated. This simplifies the telescope design and the subsequent image quality should be improved.
An orbiting telescope would also be cheaper to launch and service than one located on the Moon.

Mars. Observations from orbiting spacecraft have revealed landforms that suggest there was once water on Mars, and rovers on the surface have turned up further traces of water.
A depression on the surface that looks like a channel.
Its surface is visible because of how AU's (Astronomical Units) it is away from the Earth.

Orbiting satellites.
If you built an observatory on the lunar surface, there would be no atmosphere to battle in viewing what you needed to see. Therefore, as far as an observatory goes, one could see more due to the fact that the sky would be much more clear from the moon since it has no atmosphere than that of Earth, which does.

They use robots. Yes. They also get data from orbiting spacecraft.
True meridian through a point is the line in which a plane, passing that point and the north and south poles, intersects with surface of the earth. It thus, passes through the true north and south. the direction of true meridian through a point can be established by astronomical observations.
