The Expedition 36 trio is continuing ongoing fluids science work and the installation of a new treadmill. On the ground in Kazakhstan, three more crew members are preparing for their May 28 launch and docking to the International Space Station.

Flight Engineer Chris Cassidy continued his work with the Capillary Flow Experiment-2, also known as Vane Gap. He worked in conjunction with scientists on the ground analyzing the behavior of a dyed fluid in specially-developed science hardware. The study observes how fluids move up a surface in microgravity potentially improving the designs of fluid transfer systems such as fuel delivery devices.

Cassidy also talked to students from the Florida Institute of Technology answering questions about how living in space mentally and physically affects a crew member. He later had a ham radio pass talking about living on the space station with Talbot Middle School Students from Fall River, Mass.

Commander Pavel Vinogradov and Flight Engineer Alexander Misurkin are in the third day of installing a new Treadmill with Vibration Isolation System (TVIS) delivered in April aboard the ISS Progress 51 resupply craft. The duo removed and disassembled the old treadmill on Monday.

The TVIS, located in the Zvezda service module, helps keep crew members fit and prevents muscle atrophy that occurs in microgravity. The TVIS undergoes regular scheduled maintenance and is equipped with gyroscopes and stabilizers that minimize the dynamic forces on the space station and its systems.

The console in charge of the station’s thermal and electrical systems, or SPARTAN reported that a power channel on the P6 truss is at full power after a May 10 spacewalk repair. Spacewalkers Chris Cassidy and Tom Marshburn repaired an ammonia leak on the P6 truss after power was shutdown in the area to protect the 2B power channel.

At the Baikonur Cosmodrome in Kazakhstan three new Expedition 36 crew members, Soyuz Commander Fyodor Yurchikhin and Flight Engineers Karen Nyberg and Luca Parmitano, are preparing to join their orbiting crewmates. They will launch May 28 at 4:31 EDT aboard the Soyuz TMA-09M spacecraft and dock four orbits – or about six hours later – to the Rassvet module.
