Some information about Space exploration

Space exploration 

                 Space exploration is man's quest for knowing the unknown in space. In that effort, Manned and unmanned space probes have even crossed the borders of the solar system to collect information about the earth's neighbours, etc., 

             The era of space exploration started in 1957, when Russian (erstwhile USSR) scientists succeeded in launching an satellite in outer space. Within a few months, the United States of America (USA) also succeeded in launching its own satellite. Afterwards, USA created an independent agency for space exploration. The agency was called National Aeronautic and Space Administration (NASA). NASA has played a very important role in space exploration.
