Russian Cosmonauts to Have Pre-EVA Dress Rehearsal Today. / November 12, 2010 /

ISS-25 flight engineers Fiodor Yurchikhin and Oleg Skripochka will have pre-EVA dress rehearsal today. The cosmonauts will put on their suits and pressurize them in order to simulate EVA pressure. With their suits on, Yurchikhin and Skripochka will ‘walk’ to the airlock to validate all the steps of the EVA procedure, including off-nominals. The cosmonauts will also operate umbilical cords, locks, tools, etc.
The EVA scheduled for Nov 15, 5.30 p.m. MSK, is to last about 5 hours 55 minutes. It will cover mounting of the universal platform for scientific payloads on the outer surface of Zvezda module, Test experiment which implies sampling of the ISS outer surface, demounting of the Robotik monoblock from Zvezda surface, photo-imaging of the IPI-SM plasma injector, installation of the soft hand-rail on the Pirs module, installation of the SKK cassette on the Poisk module, operations with Zvezda and Poisk scientific hardware.
This is to be the first space walk for Skripochka, and the second one for Yurchikin during this expedition. Yurchikhin will also mark a kind of jubilee, as this will be the 5th EVA in his orbital flight career.
