    April 12 is the 50th anniversary of Yuri Gagarin's space flight, the 30th Anniversary of the first Space Shuttle flight and sees an activation of ARISSat-1 on 145.950MHz FM.

    Radio Amateurs around the world are organising events to celebrate this special anniversary.

    The AMSAT News Service (ANS) reports that Clint Bradford, K6LCS, invites those in the Mira Loma, CA area to come and have some fun that night!

    The party Web site URL is

    There will be exclusive videos to share (even one from Bill Nye, the Science Guy!), history to relate, and - if all works well (grin) - Clint will record celebratory transmissions from the International Space Station and amateur radio satellite ARISSat-1 at 5AM that morning to show you all while you are here!

    (There's another great pass of the ISS at 9:41PM - but that's technically April 13 GMT... )

    Let's use this date to promote everything we've been working on for years: the ham radio hobby, AMSAT, and the future of manned space travel.

    RSVP MANDATORY - So we'll know how many goodies to have on hand! Send an email as soon as you can, please! FAMILY- AND CHILDREN-FRIENDLY! (No pony rides, but they can pet noses of our horse and donkey!)

    Appetizers, soft drinks, a little wine, and miscellaneous munchies will be served. Prizes, handouts, and freebies to all. The rumor that an official "Yuri Gagarin Commemorative T-Shirt" being given away as a door prize has been ...

    Bring a light jacket - in case we try to work the 9:41PM pass. S'mores and fire pits outside? OF COURSE! Rain or shine ...

    Tuesday, April 12, 2011 - 6PM to 10PM

    And here I was thinking the 12th was KJ4CTS's night. It's the 27th anniversary of KJ4CTS's birth.

    Looks very exciting, I will be with a group at Caffe Trieste in downtown San Jose on April 12, I will listen with my handheld (assuming party noise is not too high). Unfortunately there will be no YN at Ames Research Center except for Education Day on April 8, http://ynba.org/2011/
    In 2008, Ames Amateur Radio Club had a large setup including EME, http://hamradio.arc.nasa.gov/yurisnight.html

    Ames hosted YN last year and like in 2008 most of the attendees are the kinds of people you usually do not see at a NASA facility. Some photos including a Yuri Gagarin posterboard at http://mfwright.com/yurigagarin/yurigagarin.html

    Last year at Ames interviewed a few 20-somethings of what do they think of celebrating a Russian space accomplishment at an American space agency facility. Generally their answer was Gagarin's flight symbolized the next evolutionary step of mankind rather than an event between competing superpowers.

    Those of you who didn't know, Yuri Gagarin was a radio amateur with the call UA1LO. He was killed in 1968 as a test pilot testing a new jet aircraft. ​

    I just heard on the news the ISS is going to be possibly hit within 2 hours or so by space debris from a 2009 china satellite,they have been ordered to take measures to escape if the station gets uninhabitable,they were told to sit in the Soyuz capsule for 10 minutes before the event and 15 after,I understand they have another 3 astronauts en route to the station supposed to get there Wednesday,hopefully they will have a station intact to dock with. Interesting times we live in,marking milestones and dealing with crises here on Earth,I sincerely hope things get better no matter where we live. 73,Michelle

    And he wasn't killed test piloting a new aircraft - I believe he was killed flying a MiG15UTI trainer while possibly hungover. He had taken to drinking as the powers that be stopped him flying in space again as he was too important and a figurehead and hero, and all he wanted to do was fly in space again. Its a bit sad really, he wanted to just be "one of the boys" of the cosmonaut corps but it wasn't allowed. Finally they relented, and he started training again, and that when he was killed.

    Soyuz TMA-21 Gagarin Spaceship Arrives at the ISS

    Russian spaceship Soyuz TMA-21 – Gagarin- has successfully docked to the International Space Station’s Poisk module today, April 7, at 03.09 MSK.
    Gagarin carrying a crew of ISS-27 increment lifted off from the Baikonur Space Center Tuesday.

    Two Roscosmos cosmonauts, Alexander Samokutyayev and Andrei Borisenko, and NASA astronaut Ronald Garan, are supposed to stay in orbit for five months.
    Like their fellow-cosmonauts ISS-27 Commander Dmitry Kondratyev, ESA’s Paolo Nespoli and NASA’s Catherine Coleman, whose orbital mission began last December, the new crew is expected to conduct from space the special jubilee events dedicated to the 50th anniversary of the first manned flight to space.
    The very name of the spaceship commemorates the Earth’s first cosmonaut Yuri Gagarin, who made a 108-minutes-long orbital rotation around the globe aboard the Vostok ship April 12, 1961.

    The crew of will face a long enough list of knotty jobs, including the docking and unloading of three Progress cargo spacecraft and joint activities with the crews of two last shuttle flights – the Endeavour that is due to blast off April 19 and the Atlantis, whose start into orbit has been scheduled for the last days of June.
    The resident crew will also make a spacewalk to service the Russian segment of the ISS.

    The transmissions will begin on Monday 11 April 2011 at 14:30 UTC and continue until 10:30 UTC on 13 April 2011.

    Due to the fact that the solar panels are covered, the satellite will be powered only by the onboard battery. The satellite will run in low power mode. This means that the transmissions will cycle ON/OFF. They will be ON for 40-60 seconds and OFF for 2 minutes.

    145.950 MHz FM Downlink:
    FM transmissions will cycle between a voice ID, select telemetry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.

    145.919 MHz CW Beacon
    The CW transmissions will be callsign ID, select telemetry, and callsigns of people actively involved with the ARISS program.

    145.920 MHz SSB BPSK-1000 Telemetry
    The BPSK transmissions will feature a new 1kBPSK protocol developed by Phil Karn, KA9Q to be readable in low signal level conditions. The BPSK data will transmit satellite telemetry. Free ground station soundcard demodulator and display software will be available.

    Note that the linear transponder will not be active during this event.

    Information declassified by Russia yesterday states he was killed trying to avoid a weather balloon.
    From Yahoo news 4/9/11
    MOSCOW (AFP) – Russia on Friday declassified documents that shed light on Yuri Gagarin's mysterious death in a training flight in 1968, saying his jet likely manoeuvred sharply to avoid a weather balloon.
    Top Kremlin archives official Alexander Stepanov told a news conference that a Soviet-era commission -- whose conclusions had until now been classified -- has concluded that this was the most likely cause of his death.
    "The conclusions of the commission are that the most likely cause of the catastrophe was a sharp manoeuvre to avoid a balloon probe," he said. Balloon probes are often used for weather-forecasting purposes.
    But he indicated that the conclusions of the commission, whose documents were de-classified to mark the half century of Gagarin's voyage into space in April 1961, had given a second possible cause for the manoeuvre.
    "A less probable cause was avoiding entry into the upper limit of the first layer of cloud cover," he added.
    <A rel=nofollow><A rel=nofollow><A title=jpeg rel=nofollow>Stepanov said he hoped the publication would quash rumours about the cause of Gagarin's death.
    "I hope they will dismiss very many speculations that are circulating in Russia in pseudo-history books," he said.
    The conclusions of an investigation were outlined in a decree of the Central Committee of the Communist Party and the Council of Ministers dated November 28, 1968, which was marked "absolutely secret."
    The presidential archive published the two-page conclusion of the commission, signed off by party chief Leonid Brezhnev, in a book of archive materials published for the 50th anniversary of Gagarin's first manned space flight.
    The book, which has more than 700 pages, was published in a print-run of only 800 copies, the Russian space agency said in a statement after the news conference.
    The book also includes the notes of the chief investigators, senior Soviet defence officials Leonid Smirnov and Dmitry Ustinov, the space agency said.
    Gagarin died on March 27, 1968, when a MiG fighter jet carrying him and instructor Vladimir Seryogin crashed in the Vladimir region outside Moscow while on a training flight.
    The commission writes that manoeuvres by Gagarin or Seryogin led the jet into a "supercritical flight regime and to its stalling in complex meteorological conditions."
    The commission created straight after Gagarin's death included defence ministry officials and aircraft designers, Stepanov said. The commission studied the flight training of the pilots and the condition of the plane.
    Over the years the death of the first man in space has been explained variously by the result of a rapid change in height to avoid an object, interference from another craft, or oxygen deprivation in the cabin.
    There has been speculation of sabotage by conspiracy theorists although this has never been backed up by evidence.
    Asked to comment on rumours that parts of the MiG are still stored in secrecy, Roskosmos deputy head Vitaly Davydov said he could not comment.

    "Roskosmos has nothing to do with the investigation of air crashes, so this question has nothing to do with us. We are not indifferent to this, but I can't say anything."
    Davydov stressed that Russia has nothing to hide about Gagarin's space flight and was not hiding any scandalous documents in secret archives.
    "Today there aren't documents on Gagarin's flight left that we have consciously kept secret because it would be damaging if they were made public," he said.
    He admitted that the Soviet authorities lied about the fact that Gagarin landed by parachute rather than inside a space capsule, as was officially announced.
    "The question was whether the cosmonaut was in the capsule or not. Then for a number of reasons they took the decision to say he was and that was how the record was registered," he said.
    He stressed that Gagarin would have set the space flight record in any case.
    The Soviet authorities acted in this way "even though everyone understood what happened and there would not have been any problem to change the way the record was registered," he said.
