NASA International Space Station On-Orbit Status 20 December 2016

The six Expedition 50 crew members from France, Russia and the United States are heading into the final holidays of the year with a muscle study and Earth observations today. The astronauts also checked out fluids and combustion science gear and practiced an emergency escape drill.
French astronaut Thomas Pesquet measured his muscle and tendon response today with assistance from Russian cosmonaut Sergey Ryzhikov. Pesquet used an ultrasound while wearing electrode stimulators around his right calf muscle. The Sarcolab experiment from the European Space Agency seeks to define which muscles are used and not used when living in space.

NASA astronaut Peggy Whitson worked on replacing gear inside an integrated rack facility that contains two racks. One rack, the Fluids Integrated Rack, studies how fluids behave in space. The other rack, Combustion Integrated Rack, enables the safe research into how flames behave and materials burn in space.

Commander Shane Kimbrough swapped sample cartridges inside the Electrostatic Levitation Furnace which enables the observation of the levitation, melting and solidification materials. At the end of the workday, he joined his Soyuz crewmates Ryzhikov and veteran cosmonaut Andrey Borisenko for an emergency Soyuz descent drill. The trio practiced the escape routes and procedures they would use in the unlikely event they would need to evacuate the station aboard the Soyuz spacecraft.

On-Orbit Status Report

Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab)-3: Yesterday, the crew configured the Muscle Atrophy Research & Exercise System (MARES) in the Columbus module. Today they completed the second of three in-flight sessions of joint-NASA-ESA-Russia Sarcolab experiment. The subject ingressed MARES, followed by the operator performing ultrasound measurements of the right calf muscle with remote guidance and direction assistance from ground specialists. Subject then donned Percutaneus Electrical Muscle Stimulator (PEMS) for electrical stimulation at rest and during voluntary muscle contraction, and Electromyography (EMG) electrodes to measure calf muscle and tendon response at the ankle (calf muscle insertion). The MARES equipment and software is used to measure calf strength during spaceflight. The inflight data will then be compared to preflight and postflight measurements to measure the impact of a hypothesized microgravity induced muscle loss. The goal of the Sarcolab investigation is to advance the understanding of muscle function and atrophy in space. Results will contribute to further improvement of countermeasures for long duration spaceflight.

Fluids Integrated Rack (FIR) Image Processing and Storage Unit (IPSU) Remove and Replace (R&R): The crew removed the degraded IPSU from the FIR and replaced it with a spare unit. Next week, the ACE-T-1 module delivered on HTV-6 will be installed and will run for 6 weeks. SpaceX-10 will deliver the Light Microscopy Module (LMM) Biophysics experiment which requires full IPSU capabilities, however, based on scheduling constraints, the IPSU was replaced prior to the ACE-T-1 exchange. The Effect of Macromolecular Transport of Microgravity Protein Crystallization (LMM Biophysics-1) studies why Proteins crystallized in microgravity are often higher quality than those grown on Earth, examining the movement of single protein molecules in microgravity. Advanced Colloids Experiment-Temperature control-1 (ACE-T-1) studies tiny suspended particles which were designed by scientists to connect themselves in a specific way to form organized structures within water. Materials having complex structures and unique properties potentially can be made with more knowledge of how these particles are joined together and the conditions which control their behaviors. FIR is a complementary fluid physics research facility designed to host investigations in areas such as colloids, gels, bubbles, wetting and capillary action, and phase changes, including boiling and cooling.

Combustion Integration Rack (CIR) Operations: The crew performed planned maintenance and troubleshooting on the CIR. In preparation for installation of the Cool Flames Investigation (CFI), the crew replaced a failed Fluids and Combustion Facility (FCF) IPSU and removed the CIR Low Light Level – Ultraviolet (LLL-UV) Imaging Package which was replaced with a CIR Intensived Camera Package. Results from the inspection were provided to ground teams for further troubleshooting procedure development. CFI provides new insight into the phenomenon where some types of fuels initially burn very hot, then appear to go out but they continue burning at a much lower temperature with no visible flames (cool flames). Understanding cool flame combustion assists scientists in developing new engines and fuels that are more efficient and less harmful to the environment.

Electrostatic Levitation Furnace (ELF) Cartridge Exchange: The crew attempted to perform the first of two days of cartridge exchange operations in Japan Aerospace Exploration Agency’s (JAXA) ELF located in Multi-Purpose Small Payload Rack (MSPR)-2. During the activity a bolt required for operations floated away. The bolt was recovered, however, due to scheduling constraints, remaining activities will require being rescheduled. ELF 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.

48S Emergency Egress On-Board Training (OBT): The 48S crew completed this OBT to practice exiting the ISS in case of an emergency. The training is scheduled for 12-14 weeks aboard the ISS and every 2.5 months thereafter.

Mobile Servicing System (MSS) Operations: Overnight, ground teams removed the failed Camera Light and Pan Assembly (CLPA) from the Space Station Remote Manipulator System (SSRMS) Tip Elbow (Boom B) and installed it onto the Mobile Transporter Relay Assembly (MTRA) wedge interface located on the Mobile Base System (MBS). A spare CLPA was flown on H-II Transfer Vehicle 6 (HTV-6) and installation on the SSRMS is scheduled as a get ahead task during the second Lithium Ion Battery replacement EVA in January. Following CLPA removal, the SSRMS and SPDM were configured in a park configuration.

H-2 Transfer Vehicle (HTV) Cargo Operations: The crew has completed ~29 hours of cargo transfer. There are ~13 hours of transfer remaining to be completed.
