Sergey Ryazansky

Sergey Ryazansky launched to the International Space Station on his first spaceflight on board the Soyuz TMA-10M spacecraft on September 25, 2013 alongside Russian cosmonaut, Oleg Kotov and American astronaut Michael S. Hopkins.

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 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.

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.

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 cosmonauts tested a new version of the Orlan space suit, deploying five nano-satellites and installing external experiments.
