The article explores space astronomy as a new scientific direction. Cosmic astronomy complements classical astronomy and is its development. Space astronomy can be considered as astronomy whose observation points are transferred from the earth's surface and near-Earth space into space onto space media. Space astronomy differs from classical astronomy not only in the transfer of observation points into outer space, but also in its methodological and organizational basis. Space astronomy, in addition to the basics of astronomy, uses new sciences as components: space geodesy, space geoinformatics, geodetic astronomy, spatial analysis, spatial logic, system analysis, computer science. The application of spatial logic is one of the features of space astronomy. The main means of observation in space astronomy is space monitoring, which uses the ideas of geoinformation monitoring. Space astronomy is a "situational" science. She not only observes, but also measures and forms management decisions. For example, the problem of selecting sites for landing spacecraft belongs to the field of space astronomy. The application of the information field model is an important difference in space astronomy. The information field is an integral model that unites different fields and allows for complex analysis and complex problem solving.
