Russian telescope Radioastron was tracking station in the U.S.

The antenna in the American Observatory Grinbenk first took data from the Russian space telescope "Radioastron" ("Spektr-R") — the emergence of a new radar station in the other hemisphere will allow scientists to double the time available for observation, said the Astro Space Center of the Lebedev Physical Institute (FIAN ), a leading scientific organization of the project.

"We are pleased to announce that the equipment was delivered to the station in the United States and installed on the telescope without problems. Tracking station first tests went very well, as a result of August 1, 2013 has been successfully written scientific data from a space telescope" — scientists report.

Until now, the scientific information with "Radioastron" could take only one tracking station, located in the suburban Pushchino.  

Because most of the time "Radioastron" is out of sight of the station, scientists can use these times to observe, and the machine "idle."

The agreement on the use of 43-m radio telescope of the National Radio Astronomy Observatory in Grinbenke (Virginia) to receive data from "Radioastron" was reached by representatives ASC FIAN and NRAO at the end of 2012. Russian experts have been delivered to the U.S. radios, identical to the one that stands at the station in Pushchino, debug it. Now this work is successfully completed: the power level of the received signal from the telescope was superior technical requirements for reliable reception, the error rate was low.

Already in the end of August, beginning active surveillance in the key scientific program "Radioastron." "The new tracking station will operate in September 2013, a few light duty … Full load a second tracking station in Grinbenke scheduled from October 2013," — said in a statement.

"Radioastron" was launched from the Baikonur cosmodrome in July 2011. It is designed to work in conjunction with ground-based network of radio telescopes, forming a single interferometer is very high angular resolution — up to seven microseconds.
