Spacecraft "Spektr-R" was perigee. / July 29, 2011 /

Specialists Federal State Unitary Enterprise "NPO. SA Lavochkin «continue planned work with astrophysical space telescope» Spektr-R ", successfully running on the target orbit July 18 from Baikonur.

According to the experts for the first time a spacecraft has successfully passed the perigee of 600 km (minimum distance to the HEO orbit between the spacecraft and Earth).

«It is quite difficult and important operation, — the deputy head of the bureau FSUE» NPO. Lavochkin "by Alexander Shirshakov electrical systems — its difficulty lies in the fact that the process is out of range of communication satellites with ground-based antenna complex, and we can not efficiently monitor the status of the satellite. In addition, this area of ​​the orbit sufficiently strong radiation belts, and radiation has a major impact on the equipment. But our spacecraft has successfully coped with the task and passed perigee. "

Also during the scheduled work on the machine «Spektr-R» run loop thermal control system of a highly stable hydrogen frequency standard time — one of the most important instrument that defines the operation of scientific equipment.

Testing and monitoring of standard on-board systems of the device continues. The next stage of work with the space telescope «Spektr-R» will be the launch of highly informative channel board — Land for the transfer of scientific data and official information about the state of the spacecraft and space radio telescope, and setting his work with the ground station based on radio telescope RT-22 Observatory, ASC LPI in Pushchino.

Space complex «Spectr-R» has been involved in the study of galaxies and quasars in the radio, the structure and dynamics of the regions adjacent to the massive black holes, neutron stars in our galaxy, the structure of the interstellar plasma and the evolution of compact extragalactic sources, the measurement of distances and velocities of pulsars and other galactic sources, the determination of fundamental cosmological parameters.
