The Expedition 50 crew is exploring a wide variety of phenomena today to understand the effects of living and working in space. Results from the advanced space research aboard the International Space Station has the potential to benefit humans on Earth and astronauts on long-term missions.

Two first-time space flyers, Sergey Ryzhikov from Russia and Thomas Pesquet from France, partnered again today for the Sarcolab muscle study. The duo used an ultrasound scanner and electrodes to measure and stimulate the knee muscles for possible muscle loss due to microgravity.

Commander Shane Kimbrough and NASA astronaut Peggy Whitson continued more maintenance work on the Electrostatic Levitation Furnace, a combustion research device that enables high temperature science. Whitson then worked on the Packed Bed Reactor Experiment gear that observes the behavior of gases and liquids.

Whitson and Pesquet later joined their Soyuz crewmate Oleg Novitskiy for a medical emergency drill. The three Expedition 50-51 crew members reviewed CPR procedures, medical hardware and their roles and responsibilities.

On-Orbit Status Report

Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight Sarcolab-3: Today's second operational day for the Sarcolab-3 experiment began with converting the Muscle Atrophy Research & Exercise System (MARES) from the ankle measurement configuration to the knee measurement configuration. The subject donned Percutaneus Electrical Muscle Stimulator (PEMS) and Electromyography (EMG) electrodes to stimulate and measure calf muscle and tendon response at the back of the knee (calf muscle origin). During the knee joint evaluation, the subject sat on the MARES dynamometer with the chair and pantograph set to obtain knee flexion and extension from 90 degree knee angle to full extension with the knee torque adapter securely fixed to the shin. The inflight data will be compared to pre and post flight measurements to measure the impact of a hypothesized microgravity induced muscle loss. Sarcolab investigates the adaptation and deterioration of the soleus, or calf muscle, where it joins the Achilles tendon which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

Packed Bed Reactor Experiment (PBRE) Module Exchange: The crew exchanged PBRE modules, removing Test Module/Wetting and installing the Test Module/Non-Wetting into the PBRE located in the Microgravity Science Glovebox (MSG) Work Volume (WV). The activity, originally scheduled for two days was successfully completed in one day. The PBRE investigation studies the behavior of gases and liquids when they flow simultaneously through a column filled with fixed porous media. The porous media or "packing" can be made of different shapes and materials and are used widely in chemical engineering as a means to enhance the contact between two immiscible fluid phases (e.g., liquid-gas, water-oil, etc.). Packed columns can serve as reactors, scrubbers, strippers, etc. in systems where efficient interphase contact is desired, both on Earth and in space.

Electrostatic Levitation Furnace (ELF): During yesterday's cartridge exchange, a bolt floated away. It was subsequently found and the exchange activities were rescheduled for today. The crew successfully removed the calibration cartridge and installed the test cartridge in the ELF. The Japanese Aerospace Exploration Agency's (JAXA) ELF is located in Multi-Purpose Small Payload Rack (MSPR)-2. It is an experimental facility designed to levitate/melt/solidify materials by containerless processing techniques using the Electrostatic Levitation method. With this facility, thermophysical properties of high temperature melts can be measured, and solidification from deeply undercooled melts can be achieved.

Japanese Experiment Module (JEM) Inter Module Ventilation (IMV) Cleaning: The crew cleaned the JEM Pressurized Module (JPM) starboard forward fan and IMV grille. The fan and grille were temporarily removed during the cleaning process.

Medical Emergency On-Board Training (OBT): The 49S crew reviewed medical emergency procedures and rescuer roles during a medical event requiring Cardiopulmonary Resuscitation (CPR) as follows:

Review emergency medical hardware configuration and determine desired deployed locations.
Determine individual preference for performing chest compressions in microgravity.
Discuss crew communication and coordination of care during an emergency medical event.
