The Expedition 25 crew members of the International Space Station prepared for the arrival of space shuttle Discovery and conducted an emergency drill Friday, capping the completion of their first full workweek as a six-member crew.

After their morning prep work and a daily planning conference with flight control teams around the world, Commander Doug Wheelock and Flight Engineers Alexander Kaleri, Oleg Skripochka, Scott Kelly, Fyodor Yurchikhin and Shannon Walker spoke with high school students visiting the Russian mission control center. The students are participants of the 18th International Space Olympiad conducted by the Korolev Municipal Committee for Education and RSC Energia.

Afterward, Wheelock guided Kelly, Kaleri and Skripochka through an egress drill to familiarize them with the location of emergency equipment along their evacuation route in the event of an emergency. This drill is just one of many activities to assist Kelly, Kaleri and Skripochka with the transition to life on the station since their arrival Oct. 9 aboard the Soyuz TMA-01M spacecraft.

Later Kelly worked with the Oxygen Generator System (OGS) to optimize flow through its thermal control system with the addition of the newly installed Sabatier reactor. Throughout the week, Wheelock installed the Sabatier, which will combine carbon dioxide from the Carbon Dioxide Removal Assembly and hydrogen from the OGS to form water and methane. The water will be recycled by the Water Processor Assembly, and the methane vented overboard.

Meanwhile, Walker and Yurchikhin spent some time sharpening their digital photography skills for the imagery they will collect of Discovery’s thermal protection system as it performs a back flip known as the Rendezvous Pitch Maneuver prior to docking. During Discovery’s final spaceflight, slated to launch Nov. 1, the STS-133 crew members will deliver important spare parts to the station along with the Express Logistics Carrier-4 and Robonaut 2.

Working in the Quest airlock, Wheelock gathered tools that will be used during the two spacewalks planned for STS-133.

Walker, Skripochka and Yurchikhin each spent about an hour loading trash and other unneeded items into the ISS Progress 37 cargo vehicle for disposal when the craft undocks Oct. 26 and is later deorbited to burn in the Earth’s atmosphere.
