The ISS and Amateur Radio

The International Space Station includes modules supplied by different countries, staffed by Astronauts from yet other countries, who perform a variety of tasks serving their countries, serving science, both for furthering advancement in space exploration and furthering good will.

There are a number of educational experiments that are conducted on behalf of students at all levels of education. In addition to all of this, there are a few Amateur Radio installations that the crew operates as time allows.

Last year, various amateur groups reported that  Paulo (ham call) PV8DX emailed the news that the International Space Station (ISS) Slow Scan Television (SSTV) on 145.800 MHz FM had been active again.

At the end of the passage (ISS) in northern Brazil where I live. I heard the sound of early SSTV. So I went to the WEBSDR in your area [the SUWS WebSDR near London, UK] and I got two images.
The ISS has been transmitting photographs devoted to the life and work of the first cosmonaut Yuri Gagarin. They were sent in the PD180 SSTV mode with additional voice commentary.

I have not found the original source or reasoning behind this, except that this is being done from the Russian Module using a Kenwood D710 transceiver. 

As a result, I've been able to receive a few of these images using a handheld radio tuned to the correct frequency, a digital record to capture the sound of the transmission, and then an open source program to decode the images on a pc.

Here are a couple:
