Micro-12: On Sunday, the crew activated all eighteen Micro-12 Group Activation Packs (GAPs) by mixing microbial media and inoculum. Then crew terminated one GAP by adding a microbial fixative to preserve the organism for subsequent ground-based characterization. Today the crew terminated additional GAPs. Micro-12 examines the effects of spaceflight on the physiology of an exoelectrogenic microorganism, Shewanella oneidensis MR-1. Exoelectrogenic microbes can pass electrons through their cell membranes, and so can be used in microbial fuel cells to make electricity from waste organic material. This investigation is expected to provide insight into how microgravity affects biological electron transport systems, and microbial fuel cell use in future space missions.
Space Algae: On Sunday, the crew photographed the Space Algae culture bags in the Veggie facility and then removed and placed them in a stowage bag for return. They then shut down the Veggie facility. The Space Algae investigation explores the genetic basis for productivity of algae cultivated in space and whether this requires genetic adaptations or not. Algae may perceive microgravity as an abiotic stress, which can trigger production of high value compounds. Investigators plan whole genome sequencing of the space-grown algal populations to identify genes related to growth in spaceflight and testing of algal composition for production of high value compounds.
NanoRacks Module-9: On Sunday, the crew activated designated mixture tubes for the fourth session of the NanoRacks Module-9 investigation. The experiments contained in these tubes support a variety of experiments sponsored by the Student Spaceflight Experiments Program (SSEP) National Center for Earth and Space Science Education (NCESSE). The student-designed experiments address challenges of living and working in space. The program is also a key initiative for US science, technology, engineering and math (STEM) education, educating and inspiring the next generation of scientists and engineers to work on the space program. Findings from student experiments may contribute to future experiments that benefit the space program.
Japanese Small Satellite Orbital Deployer 9 (J-SSOD#9): Today the crew brought the Japanese Experiment Module (JEM) Airlock Slide Table into the JEM from the JEM Airlock and removed the Handhold Experiment Platform (HXP), which was used for the Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1 investigation. They then installed a SSOD deployer on the Slide Table. The J-SSODs are used to launch small satellites from the JEM Remote Manipulator System (JEMRMS). The crew also set up and photographed flags for Malaysia, Philippines and Bhutan on the deployer. The Slide Table was then retracted back into the JEMAL. J-SSOD#9 satellite deploys are planned for August 10th.
Microgravity Investigation of Cement Solidification (MICS): Today the crew transferred a MICS ampoule kit to the ISS Portable Glovebag, broke the seal between the upper and center ampoules in each of the sample bags, and mixed the contents with a spatula.The MICS investigation supports the evaluation of microstructure and material properties of benchmark cement samples. Different responses to thermal and mechanical loading are expected and will be characterized in detail. Positive attributes found in the hardening process due to the microgravity environment aboard the ISS will be reported with the intent of improving Earth-based cement and concrete processing.
Aerosol Samplers: Today the crew deployed Active Aerosol Samplers (AASs) in Nodes 1 and 3. The battery-powered AASs will actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the cold side of the channel, where an electron microscope (EM) grid is held in place by a tiny magnet. When returned to Earth, these grids are easily removed and placed directly in an EM for analysis.
Time Perception in Microgravity: The crew performed an experiment session for ESA’s Time Perception in Microgravity investigation today. The accurate perception of objects in the environment is a prerequisite for spatial orientation and reliable performance of motor tasks. Time is fundamental to motion perception, sound localization, speech, and fine motor coordination. The Time Perception experiment quantifies the subjective changes in time perception in humans during and after long-duration exposure to microgravity.
Meteor: Today the crew replaced the diffraction grating of the Meteor camera and adjusted its position relative to the Lab Windowwithin the Window Observational Research Facility (WORF). The Meteor payload is a visible spectroscopy instrument used to observe meteors in Earth orbit. Meteor uses image analysis to provide information on the physical and chemical properties of the meteoroid dust, such as size, density, and chemical composition. Since the parent comets or asteroids of most of the meteor showers are identified, the study of the meteoroid dust on orbit provides information about the parent comets and asteroids.
AngieX Cancer Therapy: The crew performed microscope, sample and therapy operations for the AngieX Cancer Therapy 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.
Dragon Cargo Operations: Today the crew continued work on the fourth SpaceX-15 Cargo Message as they continue to pack and load items slated for return on SpX-15. Specialists estimate the crew will require up to 10 hours to finish loading the vehicle prior to the planned departure date of 3 August.
Public Affairs Office (PAO) Event: Ricky Arnold participated in an Educational Event with NASA Interns from all NASA Centers. This event was a chance for interns to speak with a crew member on the ISS and make a lasting memory to add to their internship.
Advanced Resistive Exercise Device (ARED) Maintenance: The crew performed periodic preventive maintenance on the ARED. They inspected the X-Rotation Dashpots, cycled the Main Arm through full range of motion, and greased ARED Vibration Isolation System (VIS) Rails, Rollers and Upper Stop. This quarterly maintenance is performed every 90 days.
