Russian cosmonauts Oleg Kononenko and Sergey Prokopyev headed outside the International Space Station on Tuesday to cut away thermal and orbital debris shielding from a Russian Soyuz spacecraft and inspect the ship's hull, where the station crew repaired a minor air leak in August... The inspection planned on Tuesday's spacewalk will include photo documentation of the site, and the collection of samples from any epoxy sealant that may be seeped through the hole to the outside of the Soyuz MS-09 spacecraft, before the capsule undocks Dec. 19 with Prokopyev, outgoing station commander Alexander Gerst, and NASA astronaut Serena Aunon-Chancellor.
