Sitting in front of the Soyuz TMA-18 spacecraft are (from left) Tracy Caldwell Dyson, Alexander Skvortsov and Mikhail Kornienko. The three flight engineers will join the other Expedition 23 crew members already on the station. The three-member Expedition 23 crew will expand to six on April 4 when Flight Engineers Alexander Skvortsov, Tracy Caldwell Dyson and Mikhail Kornienko dock to the International Space Station in the Soyuz TMA-18 spacecraft. On April 7, space shuttle Discovery with the seven-member STS-131 crew will visit the orbiting laboratory and deliver science racks and ammonia tanks.
Onboard the station, Japanese astronaut Soichi Noguchi and NASA astronaut T.J. Creamer, both flight engineers, configured tools and other gear in advance of the three spacewalks planned during STS-131. Commander Oleg Kotov exercised on the new treadmill and worked in the station’s Russian segment performing science and maintenance work.
