connections were deferred until the third spacewalk since the EVA was behind the time-line. Mastracchio and Anderson also installed two radiator grapple fixture stowage beams on the P1 truss. While Anderson and Mastracchio were outside, members of the STS-131 crew continued transferring items from Space Shuttle Discoverys mid-deck and the MPLM Leonardo. Overall, the crew had completed about half of the transfer work. April 12 (Flight Day 8 – Off duty) The joint STS-131/Expedition 23 crews had the morning off on flight day 8. After their morning off the crews continued their transfer activities, which are more than seventy percent complete. The crews also conducted several PAO events, including VIP events with Roscosmos, Russian president Dmitry Medvedev, RSC Energia, the Japanese Aerospace Exploration Agency (JAXA), Japanese students, astronaut Mamoru Mohri, and Japanese dignitaries. Later, commander Alan Poindexter, pilot Jim Dutton, and mission specialists Dorothy Metcalf-Lindenburger and Stephanie Wilson participated in an in-flight interview with several American media outlets including Fox News, ABC World News, and MSNBC. While the PAO events took place, Rick Mastracchio and Clay Anderson were preparing the spacesuits and tools they will use for the third and final spacewalk. Later in the day the pair will have a procedures review with other members of the ISS and shuttle crews. After the review, they will enter the airlock, close the hatch and lower the pressure to 10.2 psi and breathe pure oxygen for their campout. April 13 (Flight Day 9 – EVA 3) On flight day 9, Rick Mastracchio and Clay Anderson completed the third and final spacewalk of the STS-131 mission. Their tasks included hooking up the ammonia and nitrogen lines to the new Ammonia Tank Assembly (ATA), installing the old ATA in the shuttle's payload bay, retrieving some Micro-Meteoroid Orbital Debris (MMOD) shields, bolting a grapple bar (which had been removed from the old ATA) onto the new ATA, and preparation of some cables on the Z1 truss and tools to be used during STS-132. During the installation of the old ATA in Discoverys payload bay, the spacewalkers had some problems securing a bolt on the ATA to the LMC. The spacewalk took 6 hours and 24 minutes, bringing the total EVA time to 20 hours and 19 minutes. While the EVA was going on, commander Alan Poindexter and mission specialist Naoko Yamazaki continued transferring items from the MPLM to the ISS. Transfer is more than
