ISS Daily Summary Report – 7/30/2019

Biorock: The crew took photos of the biofilms in the Kubik 5 and Kubik 6 Biorock Experiment Containers.  The interaction between microbes and rocks in a liquid phase can be affected by reduced gravity in several ways. The reduction of thermal convection in low-gravity, and its absence in microgravity, minimizes the natural stirring in liquids and gases, and may restrict the supply of food and oxygen to the bacteria – leading to a suppression of growth, proliferation and mining performance. The goals of the Biorock investigation is to verify and quantify this assumption, and to find out if morphological and genetic changes occur in the biofilms.

Cell Science-02 (CS-02): The crew performed a growth factor injection and manual feeding for the Cell CS-02 investigation which uses osteoblast progenitor cells isolated from mouse bones to investigate the effects of microgravity on osteoblast cellular processes at the molecular and biochemical level. CS-02 uses a computational biology omics approach to investigate how osteoblasts respond to treatment with two known osteo-inductive factors. 

Combustion Integration Rack (CIR)/ Advanced Combustion via Microgravity Experiments (ACME) Manifold Bottle Exchange: The crew replaced the 40% O2 gas bottle with a 30% O2 bottle. They also replaced the ethylene fuel bottle with a hydrogen/methane mixture fuel bottle. Telemetry showed a slow leak in the hydrogen/methane bottle and teams are discussing a recovery plan. Flame Design part 1 investigation is complete and preparations are in work for transition to the s-Flame investigation. The purpose of s-Flame is to advance our ability to predict the structure and dynamics, including extinction and instabilities, of both soot-free and sooty flames. The results may contribute to the development of lean-burn engines for improved efficiency and reduced pollutant emissions here on Earth.

GRIP: The crew performed a seated science-2 session of the GRIP experiment which consists of 3 protocols: Dynamics Seated, References Seated and References Supine. They are performed in 3 separate sub-sessions.  ESA’s Grip investigation tests how the nervous system takes into account the forces due to gravity and inertia when manipulating objects.  Results from this investigation may provide insight into potential hazards for astronauts as they manipulate objects in different gravitational environments.  They also support design and control of haptic interfaces to be used in challenging environments such as space, and provide information about motor control that will be useful for the evaluation and rehabilitation of impaired upper limb control in patients with neurological diseases. 

ISS Experience: The crew set up the ISS Experience system, performed an introductory recording, and captured a GRIP seated science-2 session. The ISS Experience creates a virtual reality film documenting daily life aboard the ISS. The 8 to 10 minute videos created from footage taken during the six-month investigation cover different aspects of crew life, execution of science aboard the station, and the international partnerships involved. The ISS Experience uses a Z-CAM V1 Pro Cinematic Virtual Reality (VR) 360-degree camera with nine 190° fisheye lenses.

Nanoracks Module 9: The crew performed the ops 2 session during which the crew interacted with groups of experiment tubes from several different bags, typically by opening clamps and shaking the tubes to mix the contents. Some of the experiments involve the effects of microgravity on saturated copper sulfate crystals, the growth of several organisms in microgravity, germination of peppermint seeds in space, the curing of oil-based paint, rust formation, etc.

Treadmill 2 (T2) Status: Following last Friday’s T2 over temperature caution and subsequent ground team commanded shutdown, the team reviewed associated telemetry and confirmed that no real over temperature condition occurred. The caution message has since been inhibited and T2 is go for crew use. The team continues to investigate the caution indication and why it went into alarm erroneously.

Waste and Hygiene Compartment (WHC) Dose Pump Changeout: The crew reported a WHC Pre-Treat bad quality light indication. Following troubleshooting with the ground team, the crew successfully changed out the Dose Pump to return WHC to nominal operations. The pump is a critical part of the WHC as it injects the pre-treat liquid required to properly recycle waste urine.

4A Pump/Flow Control Subassembly (PFCS) Reset: Today a Power On Reset (POR) occurred associated with the 4A PFCS and temporarily stopped external coolant flow to the 4A batteries. Ground teams quickly assessed telemetry then worked from established procedures to recover Photovoltaic Thermal Control System (PVTCS) coolant flow. 4A Channel cooling was down for approximately 22 minutes, during which time the battery temperatures never exceeded Flight Rule limits.
