Thank you for your participation in the reception of SSTV images transmitted from the International Space Station on 15 - 17 February 2019 to celebrate the NASA On The Air and the 35th anniversary of the Amateur Radio on Human Spaceflight Missions. I am sending you your award in the attachment.

The pictures on the diploma show three events and people associated with them:

35 years ago, astronaut Owen Garriott, W5LFL took his amateur radio equipment into the Space on the Columbia STS-9 shuttle (November-December 1983). He became the first radioamateur to talk to hams while orbiting Earth. This event gave rise to the SAREX program (Shuttle Amateur Radio EXperiment, later called the Space Amateur Radio Experiment).

Sergey Samburov, RV3DR is the Chief of Cosmonaut Amateur Radio Department, RSC Energia. Thirty years ago, he was the founder and head of the MAREX program (Mir Amateur Radio EXperiment) and MIREX (Mir International Amateur Radio EXperiment) which were formed to handle prescheduled Mir school contacts. He is currently the head of the Russian Segment amateur radio activity on the International Space Station.

William Shepherd, KD5GSL commanded the first expedition on board the ISS in 2000-2001. Using the callsign NA1SS - Shepherd completed the first-ever ARISS contact on December 21, 2000. During a ten-minute radioamateur connection, he talked to 14 students of grades 1 to 8 plus a science and math teacher Rita Wright at Luther Burbank Elementary School near Chicago. We have recently celebrated the 18th anniversary of this event

Thank you for your participation in the reception of SSTV images transmitted from the International Space Station on 11 - 14 April 2019 to celebrate the Cosmonautics Day.

In the picture on the diploma one may see: Yuri Gagarin – the first human in outer space. On 12th of April 1961 he made a first orbital spaceflight around the Earth in space-vehicle Vostok. Making a single lap took him 108 minutes.

To commemorate this event, Cosmonautics Day is celebrated.

Crew of the space mission: John Young and Robert Crippen. First flight of the Space Shuttle Columbia began on 12th of April 1981, what is 20 years after first human spaceflight. NASA’s space-shuttles were used for next 30 years.

In July 2011 Christopher Ferguson, Douglas Hurley, Sandra Magnus i Rex Walheim went to the last mission at the board of Space Shuttle Atlantis – STS-135.

Alexei Leonov – the first human to conduct extravehicular activity (EVA), exiting the capsule during the Voskhod 2 mission for a 12-minute spacewalk.

Leonov was also a participant of Soyuz-Apollo mission in 1975.

Ulf Merbold – first ESA astronaut in Space. He made his spaceflight at the board of Space Shuttle Columbia – STS-9 in the period of 28th of November till 8th of December 1983.

Valentina Tereshkova – the first woman to have flown in space. She began her spaceflight on 16th of June 1963 at the board of Voskhod 6. It took 2 days 22 hours 50 minutes and 8 seconds.

Neil Armstrong – Apollo 11 mission commander. The first person to walk on the Moon. Spoke the now-famous words, "That's one small step for a man, one giant leap for mankind“. This year we celebrate 50th anniversary of this event.

Above the astronauts and cosmonauts one may see: Soyuz-Apollo orbital complex (1975), first artificial satellite Sputnik 1 (1957), then space probe Voyager 1 – currently furthest from Earth man-made object. It was launched in 1977. It moves at speed 17,024 km/s, in the distance of 20 billion kilometers from Earth. The radio signal from the probe needs 18 hours to reach Earth.

On the right of the picture one may see Soyuz TMA-19M docked at the ISS. The russian spacevehicles are currently basic means of transport of people and goods onboard the ISS after the withdrawal from service US space ferries.

Below the photo of Yuri Gagarin there is a logo of Southwest State University in Kursk (Russia). It is one of the best russian universities which is going to celebrate 50th anniversary of origin soon. Students of this university, future engineers, built „Tanusha“ satellites and participated in other space experiments.

SSTV transmissions from the International Space Station are possible thank to involvment of many people – ARISS volunteers from around the world.

Thank you for your participation in the reception of SSTV images transmitted from the International Space Station on 1 - 4 August 2019. 

SSTV images of this series are dedicated to the American scientist, astronaut and radio amateur Dr. Owen Garriott W5LFL.

Owen died on April 15th, 2019 at the age of 88.

During his rich career, he was responsible for radio communications (CapCom) with the astronauts of the Apollo 11.

In another period he was the deputy director of the Space Flight Center in the USA. Owen participated in the flight to the Skylab 3 orbital station (1973) and in the Columbia shuttle flight STS-9 mission (1983). Owen's mission aboard the shuttle in 1983 turned out to be a milestone for amateur radio.

According to AMSAT, he operated the world's first amateur radio station from space W5LFL. It starts a new era of spaceflight combined with amateur radio. Since then, a lot of shuttle flights have been taking place, flights to the MIR space station and now to the International Space Station (ISS) with the participation of astronauts and cosmonauts serving and using radio amateur equipment.

SSTV transmissions from the International Space Station are possible thank to the involvement of many people – ARISS volunteers from around the world. .
