RadioAstron Unit

RadioAstron was an international space VLBI project led by the Astro Space Center of Lebedev Physical Institute in Moscow, Russia. Launch was on 18 July 2011 and the space radio telescope was unfolded on 23 July 2011; after 11 January 2019 the spacecraft no longer responded to ground signals, and the mission was declared finished on 30 May 2019. NRAO's 140 foot antenna was used as one of two data acquisition stations, and the GBT was often used as one of the ground elements of the Earth-Space interferometer. This unit includes correspondence, memos, reports, notes, meeting minutes, journal cuts, video of a 1990 talk by Sander Weinreb, and newspaper clippings. Material is dated 1985-1998.
