NASA Space Station On-Orbit Status 20 December 2017.

Today - Zebrafish Muscle 2: Following the fixation and stowing of experiment units (EUs) from Group A earlier this week, today the crew performed fixation on the EUs from Groups B and C and then stowed them in the refrigerator of the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).

The results from Zebrafish Muscle 2 operations will help to determine whether atrophy of muscles under microgravity also occurs in zebrafish, and why that muscle atrophy occurs in microgravity. Physical exercise and control of posture are important for maintaining muscle mass and strength. In microgravity conditions, the postural, known as anti-gravity muscles, undergo atrophy because of prominent decrease in their gravity-dependent activity.

APEX-05 Operations: APEX-05 petri plates were installed into the VEGGIE facility to begin the growth process of the plants. When plants are grown in the confines of the International Space Station (ISS), they do not seem to get enough air and as a result, exhibit a stress response in their genes and proteins. The Spaceflight-induced Hypoxic/ROS Signaling (APEX-05) experiment grows different wild and mutant varieties of Arabidopsis thaliana, in order to understand how their genetic and molecular stress response systems work in space. The plants grow from seeds in the Veggie plant growth facility aboard the ISS, are frozen, and returned to Earth for detailed laboratory analysis.

Synthetic Bone BioCell Operations: During today's scheduled microscope operations for BioCell Habitats A and B, microscope issues inside the Microgravity Science Glovebox (MSG) prevented ground teams from viewing video footage of the growing bone cells from the BioCells. With the deferment of today's fixation of BioCell Habitat A, the crew was able to accelerate one of tomorrow's media exchanges to today. Ground teams will continue to resolve the issue with the microscopy video downlink and are rescheduling tomorrow's activities. Synthetic Bone uses BioCell habitats A, B, and C. The BioCell habitats will be used to test the functionality and effectiveness of new material that can assist in recovery from bone injuries or dental work during long-term space travel. Determining how well Tetranite integrates with bone cell cultures can also inform general strategies for addressing bone loss in space. Synthetic Bone examines the cellular response to a new type of bone adhesive in the microgravity environment of space. This experiment uses facilities aboard the International Space Station (ISS) to grow bone cells in the presence of a commercially available bone adhesive, and a new product called Tetranite. Sets of bone cell cultures grow with the different adhesives for 20 days and are then fixed, frozen, and returned to Earth for detailed analysis in a fully equipped biological laboratory.

Arthrospira-B (Batch Culture) Assembly: Four Arthrospira experiment containers were retrieved from a Glacier and transferred to the Columbus module where they were assembled and installed into the Biolab Incubator. The Arthrospira B experiment is an important step in making improvements in the area of closed regenerative life support systems in space which will help in making future human exploration missions beyond low Earth orbit become a reality. The cyanobacterium Arthrospira sp. strain PCC8005 is a candidate for use in spacecraft biological life support systems, for CO2 and nitrate removal, and oxygen and biomass production. However, to ensure the reliability of such a biological life support system it is necessary to characterize the response of Arthrospira sp. PCC8005 to in situ spaceflight conditions.

JAXA Low Temperature (LT) Protein Crystal Growth (PCG): PCG samples were retrieved from the Freezer-Refrigerator Of STirling cycle (FROST) and then the crew initiated the crystallization of the samples before inserting them back into the FROST where crystallization is continuing at a temperature of 4 degrees Celsius. The samples will remain in the FROST until they are returned on SpX-13 for evaluation by ground teams. The goal of the JAXA LT PCG experiment is to make high quality protein crystals in a microgravity environment at a low temperature.

Dose Distribution Inside the ISS - 3D (DOSIS 3D): Passive radiation detectors were installed in the Columbus module in support of European Space Agency's (ESA's) DOSIS 3D investigation. This experiment uses several active and passive detectors to determine the radiation doses inside the ISS and provides documentation of the actual nature and distribution of the radiation fields. A concise three dimensional (3D) dose distribution map of all the segments of the ISS will be developed based on this data and data from JAXA and NASA monitoring devices.

Japanese Experiment Module Airlock (JEM A/L) Depress: The crew depressurized the JEM A/L and vented the remaining air in preparation for upcoming NanoRacks External Platform (NREP) activities.
