The six-member Expedition 36 crew is busy at work with station maintenance, international science and robotics. The crew is also preparing for the departure and arrival of Progress resupply vehicles.
Flight Engineer Chris Cassidy conducted science work with the ongoing experiment Advanced Colloids Experiment-1 (ACE-1) inside the Fluids Integrated Rack. The experiment observes colloids, microscopic particles evenly dispersed throughout materials, with the potential for manufacturing improved materials and products on Earth.
European Flight Engineer Luca Parmitano worked inside the Columbus laboratory maintaining the Biolab. The research facility enables biology experiments on microorganisms, cells, tissue cultures, small plants, and small invertebrates in microgravity. He later worked in the Human Research Facility to make room for new hardware being delivered soon on Russian and Japanese resupply ships.
Flight Engineer Karen Nyberg worked with Robonaut 2 in the Destiny laboratory. She was assisted by Cassidy as they telerobotically tested the humanoid robot’s maneuvers transmitted from both in space and on the ground. More tests are scheduled for Tuesday.
Commander Pavel Vinogradov was assisted by Flight Engineer Alexander Misurkin as he took a graded test on an exercise bike for an observation of his cardiovascular system. Later both cosmonauts teamed up for video and photo documentation of life on the International Space Station.
Flight Engineer Fyodor Yurchikhin joined Misurkin for more work with the ongoing Russian experiment BAR. That study tests new instruments and methods for locating pressure leaks inside the orbital laboratory.
Trash and discarded gear are being stowed inside the ISS Progress 50 resupply craft which will undock from the Pirs docking compartment Thursday at 4:43 p.m. EDT. A new Progress 52 cargo craft will launch to replace it on Saturday at 4:45 p.m. and dock to Pirs about six hours later.
Japan’s fourth cargo craft to visit the station, the HTV-4, is targeted for launch Aug. 3 at 3:48 p.m. Designed by the Japan Aerospace Exploration Agency, the resupply ship will launch from the Tanegashima Space Center and deliver 3.6 tons of dry cargo, water, experiments and spare parts.
