The Chibis-M satellite, RS-39 is planned to be deployed from the Progress M-13M cargo ship into a 500 km orbit on January 24 at approximately 23:00-23:59 UTC.

RS-39 has CW beacons on 435.315 and 435.215 MHz that can be received directly by radio amateurs and schools for educational outreach purposes. Telemetry will be transmitted on these downlink frequencies. The RS-39 Morse Code telemetry format is available as an MS-Word document from:

The RS-39 team is requesting support from amateur radio operators for any reception reports of Chibis-M. Special attention is needed during the first orbits as these are outside the range of control stations. Each report will be confirmed by special QSL card.

The Space Research Institute of the Russian Academy of Sciences (RAS) will activate an e-mail address for radio amateurs around to send reception reports. The link is in Russian at present ( is available in Google English.)

Chibis-M arrived at the ISS on November 2, 2011 aboard the Progress M-13M cargo craft. It has been studying Terrestrial Gamma Ray Flashes which are hypothesized to be produced by beams of very energetic electrons, accelerated in the intense electric fields generated by large thunderstorm systems.

On January 23, 2012 Progress M-13M will undock from the ISS. Progress will then perform two orbital maneuvers to raise its orbit to 500 km. On January 24 Chibis-M will separate from the Progress cargo craft. RS-39 also carries receivers listening between 0.1 – 40 kHz and 26-48 MHz for a space weather experiment.
