YouTube Space Lab!


We're asking you to come up with a science experiment for space and upload a video explaining it to YouTube. If your idea wins, it will be performed on the International Space Station and live streamed on YouTube to the world. And we'll throw in some out-of-this-world prizes, too.

Letter from Wolfgang (DL6SDA)

"Hi, I could receive Kedr RS01S yesterday, Saturday 13th of August 2011 from 20.27 - 20.30 UTC at 145.950 MHz using a FT-736 with 7 element horizontal yagi. Maximum elevation in this path was 5degrees. I also could read the 2 sstv pictures at least partly. A beautiful experiment for all radio amateurs. Vy73 de Wolfgang, DL6SDA "

Video KEDR


August 3, 2011, Russian cosmonaut Sergei Volkov has successfully launched microsatellite "Kedr" in Earth orbit.

"Kedr" - Satellite Rocket and Space Corporation "Energia". In the manufacture and delivery of individual units and systems involved AMSAT-NA and SWSU of scientific equipment "vakkummetr."

His call sign - "Kedr" satellite was in honor of the 50th anniversary of the first manned flight into space. Students design and technology department of computing resources YUZGU designed and manufactured its own vacuum gauge - with the help of his students are going to find out how the fluxes of charged particles in space on the ionization gauge readings.

Initially, satellite planned for launch in December last year.

- In late January, "Kedr" was delivered by truck to the ISS - says assistant professor of design computing resources SWSU, head of the club "Sporadik" Valerian Picchi - but after the launch date was postponed several times. And on August 3 at 14 hours GMT, about 16 pm local time, he went into free flight. The satellite is located all the necessary equipment - solar panels, batteries, scientific instruments, which have made our students. In particular, there is a recording device, a cloud of molecules in space.

True, the long-awaited launch was not without incident. In the satellite suddenly lost one of the two antennas, it is clear that even in outer space. As a result, the astronauts had to pull the machine back to the outlet manhole. But all ended well - a few hours running all the same place.

"Kedr" for six months will plow expanses of space, participating in research.

From orbit it passes in the automatic mode 25 welcome messages in 15 languages, pictures of the Earth and telemetry information. In addition, satellite broadcasts and amateur radio frequencies - namely, 145.95 MHz. Can hear him every ham in the world.

During the first day of the flight was taken on 19 signals from orbit, which confirms the proper functioning of all systems of the microsatellite.

ARISSat-1/Radioskaf-b cataloged


ARISSat-1 also known as Radioskaf-b or Kedr has been given a catalog number of 37772 and called Radioskaf-b in the Keplerian list.

Graham Shirville, G3VZV notes that ARISSat-1 leads the ISS by 20 seconds and is less than 1 km below it.

Congratulations to the ARISSat-1/KEDR Team


As the satellite was deployed from the International Space Station beginning its mission AMSAT President Barry Baines, WD4ASW, observed, "Welcome to a new era as AMSAT returns to space with ARISSat-1/KEDR. I encourage all hams, SWLs, educators, and experimenters to enjoy the unique opportunity presented by this mission to learn about amateur radio in space, enhance and improve your station, and hone your operating skills as you try out all of this satellite's available features."

Barry continues, "ARISSat-1/KEDR marks a new type of satellite which has captured the attention of the national space agencies around the world for the unique educational opportunity we have been able to design, launch, and now operate. By designing an educational mission aligned with NASA's Science, Technology,Engineering, and Mathematics goals amateur radio operators around the world can now enjoy a new satellite in orbit."

ARISSat-1/KEDR Project Manager, Gould Smith, WA4SXM said, "Dozens of amateur radio volunteers, AMSAT, ARRL, NASA, and Energia have teamed up for this successful mission to bring you the most unique and innovative amateur radio satellite mission flying 220 miles above your QTH at 17,500 mph! Congratulations to all who made ARISSat-1/KEDR successful!"

Continuing, Gould said, "ARRISat-1/KEDR has been developed, built, and tested by a remarkable team of radio amateurs. As the Project Manager for ARISSat-1/KEDR these past three years I have had the opportunity to work with a team of creative people to get to where we are now ... IN ORBIT!"
