For the execution of Roscosmos Order No. 197, dated December 7, 2010 to organize the unified cosmonaut detachment in late December 2010 Riazansky quitted his job at SSC RF-IBMP RAS. Since January 1, 2011 by Order of CTC Head he was enlisted in Yu.A. Gagarin CTC detachment and appointed to the post of test cosmonaut, thus Riazansky was the first cosmonaut who transferred to CTC detachment.
On January 28, 2011 it was reported that he was assigned as a flight engineer to the prime crew of the ISS-37/38. On February 18, 2011 his assignment was confirmed in ESA press release No.08-2011.
