Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) SmoothNav: The crew set up the SPHERES work area to activate and check out the hardware and EXPRESS laptop computer (ELC) before conducting the SmoothNav experiment run. SmoothNav develops an estimation algorithm aggregating relative state measurements between multiple, small, and potentially differently instrumented spacecraft. The algorithm obtains the most probable estimate of the relative positions and velocities between all spacecraft using all available sensor information, including past measurements. The algorithm remains portable between different satellite platforms with different onboard sensors, adaptable in the case that one or more satellites become inoperable, and tolerant to delayed measurements or measurements received at different frequencies.
Cell Biology Experiment Facility (CBEF) Configuration Change: The crew changed the configuration of the CBEF and cleaned the inside of the incubator unit to prepare the facility for the Mouse Stress Defense investigation arriving on SpaceX-14. The CBEF is a Japan Aerospace Exploration Agency (JAXA) sub-rack facility located in the Saibo (living cell) Experiment Rack. The CBEF is used in various life science experiments, such as cultivating cells and plants in the Japanese Experiment Module (JEM) and consists of an incubator and control equipment for control and communications.
Tropical Cyclone: The crew configured the camera settings in the Cupola to take untended images of the Category 4 Typhoon Cebile in the Southern Indian Ocean. The Tropical Cyclone investigation captures images of tropical cyclones and hurricanes that are rated at Category 3 or greater on the Saffir-Simpson scale. A pseudo-stereoscopic method is used to determine the altitudes of the cloud tops near the center (eye) of a cyclone by precisely tracking the apparent positions of cloud features with respect to the Earth and how those positions change over time as an observer (the ISS in this case) passes over the storm. The photographic images will be used to demonstrate that pseudo-spectroscopy can be used to measure the cloud altitudes to sufficient precision so that, when combined with other remote-sensing data, an accurate determination of the intensity of hurricane or cyclone can be made.
Internal Thermal Control System (ITCS) Water Sampling: Today the crew sampled fluid from the ITCS for return and analysis on the ground. This is regularly scheduled preventive maintenance to verify health of the ITCS.
Eye exams: The crew completed routine OCT and Fundoscope eye exams today. Eye exams are performed regularly onboard in order to monitor crewmembers eye health. Eyesight is one of the many aspects of the human body that is affected by long-duration stays in a microgravity environment.
