Space Probes

Space Probes

Space probes carry everything that is needed by astronomers during a mission. These probes complete their work in three basic steps. Firstly, it studies the target, then it acts as an orbiter and at last it lands on the target. Pioneer 10 and 11 were the first probes to visit the outer Solar system. They were especially designed to travel in the space. Most of the space probes use solar cells to produce electricity from the sunlight Pioneer  10 and 11 travelled so far that the solar cells failed to work and thus nuclear power generator were used in order to make electricity. The Rosetta space probe has two parts ‘The Lander craft’ and ‘ The Orbiter’.It will study the comet in detail and bring information about it.
