Sergey Nikolayevich Ryazansky (Russian: Серге́й Николаевич Рязанский; born November 13, 1974) is a Russian cosmonaut. He was selected as commander of the IMBP-6 cosmonaut group in 2003, but later transferred to the TsPK Cosmonaut Group.[1] Ryazansky made his first spaceflight aboard the Soyuz TMA-10M/Expedition 37/Expedition 38 mission from September 2013 until March 2014.

Personal

Ryazansky was born in Moscow, Soviet Union. He is the grandson of Mikhail Ryazanskiy, chief Soviet guidance designer of the Sputnik era.[2][3] Ryazansky is divorced with one child. [4]

Education

Sergey Ryazansky attended Moscow State University and graduated as a biochemist in 1996. After college he began working as a researcher at the Institute of Biomedical Problems.

Cosmonaut career

Ryazansky was selected as a research and test cosmonaut in 2003. He completed training in 2005. In 2009 he participated in a 105 day mission as part of phase two of the Mars 500 program.

Expedition 37/38

Ryazansky exercises on the Treadmill Vibration Isolation System (TVIS) in the Zvezda Service Module.

Sergey Ryazansky was launched to the International Space Station on board the Soyuz TMA-10M spacecraft on September 25, 2013 alongside Russian cosmonaut, Oleg Kotov and American astronaut Michael S. Hopkins. He served as a Flight Engineer on Expedition 37 and Expedition 38 before returning to Earth aboard the Soyuz on March 11, 2014.

Spacewalks

Sergey Ryazanskiy is pictured during his first career spacewalk on 9 November 2013.

Ryazansky performed his first spacewalk outside the ISS with cosmonaut Oleg Kotov on 9 November 2013,. They took the Olympic torch for the 2014 Winter Olympic Games outside ISS. They also continued work on an extravehicular activity workstation and biaxial pointing platform by removing launch brackets and bolts, as well as retrieving an experimental package. The planned installation of a foot restraint on the mounting seat of the workstation was deferred to a future spacewalk after the spacewalkers noticed some issues with its alignment. The spacewalk lasted 5 hours 50 minutes.

On 27 December 2013, Ryazansky and Kotov were again outside of the ISS to perform a spacewalk. The cosmonauts attached two (high and medium resolution) cameras as part of a commercial agreement between a Canadian firm and the Russian Federal Space Agency to provide Earth views to internet-based subscribers. Kotov routed the data and telemetry cables for the medium resolution camera, however, flight control team at the Russian Mission Control Center did not see the expected telemetry and electrical connectivity from the cameras. Eventually, the cosmonauts were instructed to remove the cameras and return them back inside the ISS for further analysis. In addition to the camera installation work, Ryazansky and Kotov also removed and jettisoned the Vsplesk experiment package designed to monitor seismic effects using high-energy particle streams in the near-Earth environment. The spacewalkers next attached the more sophisticated earthquake-monitoring Seismoprognoz experiment to a Zvezda handrail. The spacewalk lasted 8 hours and 7 minutes and extended the record for the longest Russian spacewalk set by Expedition 36 cosmonauts Fyodor Yurchikhin and Alexander Misurkin, who conducted a 7 hour, 29 minute spacewalk on 16 August 2013.[5]

On 27 January 2014, Ryazansky did perform his third spacewalk outside the ISS with cosmonaut Oleg Kotov.[6] The cosmonauts completed work that could not be finished up during their last spacewalk on December 27. After exiting the Pirs docking compartment, the two cosmonauts arrived at the outside of the Zvezda service module. They then installed a high resolution camera and a medium resolution camera to capture Earth imagery, however the medium resolution camera again experienced telemetry issues. Ryazansky and Kotov also removed a cassette container attached to the Pirs docking compartment, installed earlier as part of a materials exposure experiment. They also removed a worksite interface adapter attached to a portable data grapple fixture on the Zarya module to ensure that future operations with the Canadarm2 robotic arm will not be disrupted. The spacewalk marked the fourth EVA conducted during the Expedition 38 and lasted six hours and eight minutes.
