The KRT-10 radiotelescope space antenna is described. It has a 10 meter umbrella, collapsible support radiators, four megaphones for the 12 centimeter band and a spiral for the 72 centimeter band attached to its body, high frequency radiation meter amplifiers, and a heat regulation system located in the hermetically sealed compartment. The antenna mirror has a reflective surface made from a specially knitted grid bed, woven from 50 micrometer thick metallic fibers. Onboard astrophysical studies using the antenna were conducted for the development of radioastronomical methods in space in two modes: circular rotation of the craft around a transverse axis for mapping of the Milky Way and constant orientation of the craft for observation of a pulsar, together with a 70 meter radiotelescope in the Crimea. Geophysical studies produced high resolution in measurements from space of the radio temperature brightness of the Earth and the world's oceans. Evaluations were conducted of the actual resolution of the antenna and data were taken on the quality of its opening. Signal reception capability was found dependent on the 'mirror' surface. Antennas of large ground radiotelescopes with diameters of approximately 100 meters are being constructed and design of folding antennas with diameters of 30 and 10 meters using the same principle as the 'KRT-10' is being implemented.
