Lighting Effects: Upon wakeup, a 53S subject provided a daily sleep log entry to track his sleep patterns and wakefulness. The Lighting Effects experiment hopes to better quantify and qualify how lighting can effect habitability of spacecraft. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. The Lighting Effects investigation studies the impact of the change from fluorescent light bulbs to solid-state light-emitting diodes (LEDs) with adjustable intensity and color and aims to determine if the new lights can improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have major implications for people on Earth who use electric lights.

Plant Gravity Perception Operations European Modular Cultivation System (EMCS): The crew replaced the EMCS Thermal Control System (TCS) cold spot sponge before replacing the Experiment Containers (ECs) on the EMCS rotors with new ECs to begin the next Plant Gravity Perception experiment run. The Plant Gravity Perception investigation germinates normal and mutated forms of thale cress, a model research plant, to study the plants’ gravity and light perception. Results provide new information about plants’ ability to detect gravity and how they adapt to an environment without it, which benefits efforts to grow plants for food on future missions. The EMCS is an experiment facility that is dedicated to studying plant biology in a reduced gravity environment. It supports the cultivation, stimulation, and crew-assisted operation of biological experiments under controlled conditions. The facility has performed multi-generation (seed-to-seed) experiments and studies the effects of gravity and light on early development and growth, signal perception and transduction in plant tropisms.

Combustion Integrated Rack (CIR) Manifold #2 Bottle Replacement: The crew removed and replaced a CIR manifold #2 bottle on the front of the optics bench. CIR provides sustained, systematic microgravity combustion research and it houses hardware capable of performing combustion experiments to further research of combustion in microgravity. This is for the ACME investigation which is a set of five independent studies of gaseous flames to be conducted in the CIR. ACME’s primary goal is to improved fuel efficiency and reduced pollutant production in practical combustion on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability.

NanoRacks DreamUp Xtronaut Crystal Growth (DreamXCG): The crew continued to track the progression of the DreamXCG formation that was initiated two weeks ago, by taking photo and video images of each pouch to show any visible sugar crystal growth. This investigation teaches students about the effects of microgravity on crystal formations using near-identical flight kits flown and operated aboard the International Space Station (ISS). With access to crew member videos and data on the same experiment, students are able compare crystal formations in space to those in their classrooms. The investigation aims to promote science, technology, engineering, and math (STEM) fields to the next generation of students.

Tropical Cyclone: The crew configured the camera settings in the Cupola to take untended images of the Category 3 Typhoon Gita, near the South Pacific island nation of Tonga. The Tropical Cyclone investigation is used to capture 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.

Earth Imagery from ISS Target (EIISS): Using the RED camera, the crew captured images of the Amazon River, the Gulf of Thailand, and the Baja Peninsula. EIISS is used to support creation of a series of videos showcasing Earth views taken from space. The videos are taken with cameras on the ISS in 6K hi-resolution and are integrated into videos for screensavers for public enjoyment, exploration, and engagement.

Columbus Mass Memory Unit (MMU) Memory Card Replacement: Today, the crew replaced one of the Memory Cards to restore internal redundancy in MMU2. To gain access to MMU2, the crew rotated the Human Research Facility 1 (HRF-1) rack and performed the memory card replacement.
