Space research is scientific studies carried out using scientific equipment in outer space. It includes the use of space technology for a broad spectrum of research disciplines, including Earth science, materials science, biology, medicine, and physics. The term includes scientific payloads everywhere from deep space to low Earth orbit, and is frequently defined to include research in the upper atmosphere using sounding rockets and high-altitude balloons. Space science and space exploration involve the study of outer space itself, which is only part of the broader field of space research. Major Space Research Agencies in the World.
For centuries, the Chinese had been using rockets for ceremonial and military purposes. But it wasn’t until the latter-half of the 20th Century where rockets were developed to overcome Earths’ gravity. Such advances were made simultaneously in three countries by three scientists. In Russia, Konstantin Tsiolkovski, in the United States was Robert Goddard, and in Germany was Hermann Oberth.
After the end of World War II, the United States and the Soviet Union created their own missile programs and space research emerged as a field of scientific investigation based on the advancing rocket technology. In 1948-1949 detectors on V-2 rocket flights detected x-rays from the Sun.Sounding rockets proved useful for studies of the structure of the upper atmosphere. As higher altitudes were reached, the field of space physics emerged with studies of aurorae, the ionosphere and the magnetosphere. Notable as the start of satellite-based space research is the detection of the Van Allen radiation belt by Explorer 1 in 1958, four months after the launch of the first satellite, Sputnik 1 on October 4, 1957. In the following year space planetology emerged with a series of lunar probes, e.g. the first photographs of the far side of the Moon Luna 3 in 1959.
