ISS Daily Summary Report – 8/07/2018

Japanese Experiment Module (JEM) Moderate Temperature Loop (MTL) Leak Update: The JEM MTL leak continues with the rate of 20 mL/day. On Friday, the crew completed a visual inspection of the Gas Trap Bypass Valve in the JEM Thermal Control System (TCS)2 rack but were unable to find evidence of a leak. They also isolated the Multi-purpose Small Payload Rack (MSPR)1 and MSPR2 racks from the JEM MTL line. The leak continued over the weekend, however, exonerating those racks as the leak source. Today the crew isolate EXPRESS Rack #5 as teams continue to search for the source of the leak.

Advanced Combustion via Microgravity Experiments (ACME): The crew replaced the Combustion Integrated Rack (CIR) manifold bottles today to support the second part of the Coflow Laminar Diffusion (CLD) Flames investigation that began during the previous increment pair. The ACME experiment series being performed in the CIR includes five independent studies of gaseous flames. CLD Flames is one of the five independent studies with an overall goal to improve our understanding of the physical and chemical processes controlling diffusion flame structure and lifting phenomena and to provide for rigorous testing of numerical models, including thermal radiation, soot formation, and detailed chemical kinetics. Such understanding allows for detailed computational predictions of pollutant formation and enables the improvement of combustion efficiency and reduction of pollutant emission in practical terrestrial combustion. The primary goals of ACME are to improve fuel efficiency and reduce pollutant production in routine fuel combustion activities on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability.

Fluid Shifts: To prepare for tomorrow’s Fluid Shifts Imaging Measurement test, today the crew setup the Cerebral and Cochlear Fluid Pressure (CCFP) analyzer hardware and performed a CCFP functional checkout and data transfer. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the head ward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

Center for the Advancement of Science in Space (CASIS) Protein Crystal Growth (PCG) 13:  Today the crew removed and stowed the CO2 incubator and meter from the Space Automated Bioproduct Laboratory (SABL) and completed a hard drive swap to prepare the facility for CASIS PCG 13 activities next week. CASIS PCG 13 seeks to enhance the way crystals are grown in a microgravity environment by allowing crew members to observe imperfections within a crystal and make real-time adjustments to follow-up experiments, rather than returning a sample to Earth and relaunching to try again. This dramatically reduces the time it takes to conduct an experiment aboard the space station and creates a timely, realistic and more cost-effective solution for prospective researchers. 

AngieX Cancer Therapy:  In conclusion of last week’s AngieX Cancer Therapy activities, today the crew removed and stowed the Microgravity Science Glovebox (MSG) life science hardware used to conduct the investigation. The AngieX investigation examines whether endothelial cells cultured in microgravity represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels.  AngieX has developed a treatment that targets both tumor cells and vasculature, but needs a better model on which to test it. This study may facilitate development of a cost-effective method that does not require animal testing and which may help develop safer and more effective vascular-targeted drugs.

MagVector 3D: The crew performed two sample exchanges for ESA’s MagVector 3D sample yesterday.  Twelve different samples will be processed on the ISS.  MagVector supports a study of how Earth’s magnetic field interacts with an electrical conductor. Using extremely sensitive magnetic sensors placed around and above a conductor, researchers can gain insight into ways that the magnetic field influences how conductors work. This research is expected to help improve future ISS experiments and electrical experiments, and could offer insights into how magnetic fields influence electrical conductors in general. 

Barrios Protein Crystal Growth (PCG): Yesterday the crew retrieved a Barrios PCG microplate from a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) and inserted the samples into the Space Automated Bioproduct Laboratory (SABL).  Barrios PCG focuses on the successful transfer and mixing of different solutions into commercial off-the-shelf multiwell plates. Video of the growth of the protein crystals in the multiwell plates will be downlinked for evaluation. 

Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) Zero Robotics: Today the crew set up cameras for the SPHERES Zero Robotics investigation and completed a dry run session.  The SPHERES-Zero-Robotics investigation establishes an opportunity for high school students to design research for the ISS. As part of a competition, students write algorithms for the SPHERES satellites to accomplish tasks relevant to future space missions. The algorithms are tested by the SPHERES team and the best designs are selected for the competition to operate the SPHERES satellites on board the ISS.

Microbial Tracking-2 (MT-2):  Today the crew collected saliva and body samples for the Microbial Tracking-2 investigation and placed them inside a MELFI.  MT-2 monitors the different types of microbes that are present on ISS over a 1-year period.  After the samples are returned to Earth, a molecular analysis of the RNA and DNA will be conducted to identify the specific microbes that are present on ISS in order to understand the microbial flora diversity on the ISS and how it changes over time.

Sextant Navigation: Today the crew calibrated the sextant and then performed the second session for the Sextant Navigation investigation. This session will emphasize position stabilization and sighting. Following data collection, the crew will record the results and stow the equipment. The Sextant Navigation investigation focuses on stability and star sighting opportunities in microgravity. Astronauts onboard the ISS test a hand-held sextant that is intended for use on future Orion exploration missions. The results from this investigation can aid in the development of emergency navigation methods for future manned spacecraft. Historically, Gemini missions in 1965-66 were the first to exercise sextant sightings from a spacecraft. A sextant was built into Apollo vehicles as a navigation backup in case of lost communications.

Preparation for H-II Transfer Vehicle (HTV)-7 Rack Relocations: This week the crew will execute a series of activities in order to prepare ISS for the installation of new racks arriving on HTV-7. Today the crew reviewed procedures, cleared stowage from rack fronts in the Permanent Multipurpose Module (PMM) and reorganize stowage in the Japanese Experiment Logistics Module – Pressurized Section (JLP) and Japanese Logistic Module (JPM). These activities, coupled with tomorrow’s continued disassembly of the decommissioned Muscle Atrophy Resistive Exercise System (MARES) rack in the PMM, will enable the crew to transfer five racks within ISS on Thursday.

Mobile Servicing System (MSS) Operations: Overnight, robotics ground controllers used the Space Station Remote Manipulator System (SSRMS) to survey cable configurations in the S0 Bay 1 area for ExtraVehicular Activity (EVA) planning. Once complete, specialists executed a walk-off from the Node 2 Power Data Grapple Fixture (PDGF) to Mobile Base System (MBS) PDGF 4, translated the Mobile Transporter (MT) from Worksite (WS)6 to WS7, and unstowed Special Purpose Dexterous Manipulator (SPDM). SSRMS remains in a park position in preparation for tonight’s activity to break torque on Channel 2A battery bolts in preparation for the upcoming HTV-7 Battery R&R EVAs.
