The Russian Tomsk-TPU-120 CubeSat is different from other CubeSats it has
a handle!

The 3U CubeSat was launchedÂ*from Baikonur to the ISS on March 31, 2016 in a
Progress-MS-2 cargo vessel. It will be deployed by hand during a future
Russian spacewalk (EVA), which is why it has a handle.

The satellite was developed by students at the Tomsk Polytechnic University
to test new space materials technology and will be the worlds first space
vehicle with a 3D-printed structure.

In May 2016 Tomsk Polytechnic University celebrates its 120th anniversary.
As part of the celebrations on May 10-11 Tomsk-TPU-120 will be activated in
the ISS and will transmit a greeting to Earth inhabitants, recorded by
students of the university in 10 languages: Russian, English, German,
French, Chinese, Arabic, Tatar, Indian, Kazakh and Portuguese.

The greeting signal will be transmitted once a minute on 437.025 MHz FM.
One of the Kenwood transceivers (TM D700) on the ISS will provide a
cross-band relay, re-transmitting the signal on 145.800 MHz FM.

Dmitry Pashkov R4UAB reports that on May 5 the Russian ISS crew will charge
the satellite battery, connect the antenna and configure the Kenwood
transceiver for relay operation, they will then make a test transmission.

Dmitry operates a WebSDR which you can use to receive the transmissions
when the ISS is over Russia http://websdr.r4uab.ru/

The next Russian spacewalk appears to be EVA-43 which expected to take
place in early 2017 http://spaceflight101.com/iss/iss-calendar/

SamSat-218 lead developer Efim Ustiugov with Professor Igor Belokonov

Two Russian satellites AIST-2D and SamSat-218 operating in the Amateur
bands were launched on April 28, 2016 at 02:01 UT on a Soyuz 2-1A launch
vehicle from the new Vostochny Cosmodrome located in the Amur Oblast. The
satellites were placed into aÂ* 471 km × 485 km orbit with a 97.3°
inclination.

AIST-2D weighs 500 kg and is a technology demonstration and scientific
research satellite developed at Samara Aerospace University. The 3U CubeSat
SamSat-218 was developed by students at the Samara State University and
weighs just 4 kg.
