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.
