ISS039-E-020699 (13 May 2014) --- Japan Aerospace Exploration Agency astronaut Koichi Wakata, Expedition 39 commander, places his crew patch on a wall in the Quest airlock of the Earth-orbiting International Space Station. A short time later, Wakata joined Expedition 39 Soyuz Commander Mikhail Tyurin of Roscosmos and Flight Engineer Rick Mastracchio of NASA as they departed the orbital outpost in a Soyuz vehicle. Wakata had spent a great deal of time in Quest as he assisted spacewalks from the shirt-sleeve environment of the orbital outpost on both Expedition 38 and 39.
