The ARISS Series 31 images consist in 12 pictures commemorating wants Cosmonauts Day, the 100th anniversary of liquid-fueled rockets, the inaugural Space Shuttle launch and SuitSat!
The certificate shows people associated with these events. From left:
Konstanin Tsiolkovsky was a visionary and theoretician. He focused on the mathematical foundations of space flight, developed the rocket formula (the Tsiolkovsky equation), and designed theoretical models of liquid-fuel rockets.
Robert Goddard – He was an engineer and practitioner. He focused on construction and testing. He launched the first liquid-fueled rocket in history in 1926.
The crew of the first space shuttle flight: John Young and Robert
Crippen. The STS-1 mission aboard the Space Shuttle Columbia launched on April 12, 1981.
Exactly 20 years earlier, the first man in the world, Yuri Gagarin,
made the first space journey on board the Vostok-1 spacecraft.
20 years have passed since another important event for radio amateurs.
SuitSat! (RadioSkaf) – a worn Russian Orlan spacesuit with an attached amateur radio transmitter. It was assembled by the crew of the Soyuz TMA-7 mission residing at the International Space Station. It was launched into orbit on February 3, 2006, and operated for six months. It burned up in Earth's atmosphere on September 7, 2006.
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). The primary goal of ARISS is to promote exploration of science, technology, engineering, the arts, and mathematics topics. ARISS does this by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students. Before and during these radiocontacts, students, educators, parents, and communities take part in hands-on learning activities tied to space, space technologies, and amateur radio.
