Cosmonauts Manually Deploy Three Nanosatellites with Amateur Radio Payloads

International Space Station (ISS) Expedition 52 Commander Fyodor Yurchikhin, RN3FI, and Flight Engineer Sergey Ryazanskiy manually deployed five nanosatellites during a spacewalk on August 17. Three of the satellites carry Amateur Radio payloads. Tanyusha-SWSU 1 and 2 (also known as also known as Radioskaf 6 and 7 — RS6S and RS7S) will transmit either 9.6 kB FSK or FM voice announcements on 437.050 MHz, while Tomsk-TPU-120 (RS4S) will transmit FM voice announcements on 437.025. The satellites were deployed from the Pirs airlock module of the ISS. Both have been reported active.

Tanyusha 1 and 2 will transmit greetings in Russian, English, Spanish, and Chinese.

Tomsk-TPU-120 was developed by students at Tomsk Polytechnic University (TPU) to test new space materials technology. It is the first-ever space vehicle with a 3D-printed structure. It was launched to the ISS in March as part of a cargo shipment.
