The study of geospace occupies a prominent place among the development of modem science nowadays. The Earth's electromagnetism is responsible for the emergence and preservation of geophysical laws, climatic and biospheric transformations, and geospace actually describes a special mechanism of interaction of the Earth's own magnetic field with the external cosmic electromagnetic environment, with the help of which the gas-plasma shells of the Earth were formed. The work describes some methods of geospace research, in particular, the usage of robotic devices and the samples from the surfaces of other planets.
