AMSAT PRESS RELEASE - ARISSat-1 Not Heard During Gagarin Commemoration. The planned operation of ARISSat-1/RadioSkaf-V/KEDR on April 11 and April 12 from inside the International Space Station as part of the commemoration of the 50th anniversary of Yuri Gagarin's flight was not successful. No earth stations on the ground
reported hearing transmissions on the ARISSat-1 downlink(145.950 MHz for FM analog/145.920 MHz for digital). The press release
ARISSAT-1 UPDATE - The ARISSat-1 satellite inside the ISS, was to be turned on and use an external antenna in celebration of the 50th anniversary of Yuri Gagarin's first manned space flight. No ground stations reported hearing the signals. AMSAT is working with our Russian partners to determine any problems and assist in correcting them. Full story
ARISSAT-1 TO BE ACTIVATED ABOARD ISS ON APRIL 12 - The ARISSat-1 satellite, presently still inside the ISS, will be turned on and use an external antenna on 12 April 2011 to celebrate the 50th anniversary of Yuri Gagarin's first manned space flight. AMSAT will support this event and issue certificates to those stations reporting reception of the ARISSat-1 signals. Roscosmos has announced that the satellite will be deployed into orbit during the next EVA in July of this year.Full story
NO WEDNESDAY DEPLOYMENT OF ARISSAT-1 - AMSAT learned on Friday morning, 11 FEB 11 that the deployment of the ARISSat-1 satellite had been removed from the RSA EVA 28 timeline by RSC-Energia management. NASA was informed that the ARISSat-1 deployment would be deferred to a later RS EVA, due to changes in the tasks associated with the configuration of RS pay-loads to be performed during RS EVA 28. Subsequently, RSC-Energia informed NASA that deployment of ARISSat-1 will be added to RSC EVA 29 currently scheduled for July 2011. Full story
ARISSAT-1 TRANSMITS FROM THE INTERNATIONAL SPACE STATION
- The crew of the International Space Station attached the AMSAT ARISSat-1 satellite to the station's external antenna and made several test transmissions this afternoon on 2 meters. A number of amateurs heard the test signals on 145.950 MHz FM, including Roland, PY4ZBZ, in Sete Lagoas, Brasil, who recorded the audio (click here to listen). Full story

PLANS TO LAUNCH A SECOND "SUITSAT" spacesuit-turned-satellite were the subject of discussions and presentations at the recent AMSAT Space Symposium and Amateur Radio on the International Space Station (ARISS) International Delegates' meeting near San Francisco. Despite a weaker-than-anticipated 2-meter signal, SuitSat-1 -- a surplus Russian Orlan spacesuit fitted with an Amateur Radio transmitter -- sparked the imagination of students and the general public and turned into a public relations bonanza for Amateur Radio. ARISS now hopes to capitalize on the concept by building an even better SuitSat that will include ham radio transponders. Full story
ELEVEN ELECTRICAL ENGINEERING STUDENTS at The College of New Jersey had a hand in designing some of the software defined radio (SDR) hardware that will fly aboard SuitSat-2.
