52Soyuz Landing Preparations: Crew and ground teams continued to prepare for tomorrow’s planned 52S Undock and landing. 52S is scheduled to undock tomorrow at 5:09 PM CST with landing at 8:31 PM CST. Today’s activities included packing 52S with return cargo, Emergency Roles and Responsibilities Review, and Change of Command Ceremony.
Lighting Effects: Upon wake up the 53S subject completed the two week sleep session study by providing daily sleep log entries to track his sleep patterns and wakefulness. 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.
Microbial Tracking-2 (MT-2): Over the weekend and today a 52S subject provided saliva samples to support the MT-2 investigation. The MT-2 series continues the monitoring of the types of microbes that are present on the ISS. It seeks to catalog and characterize potential disease-causing microorganisms onboard the ISS. Crew pre-flight, in-flight, and post-flight samples and environmental samples from ISS surface and air locations are collected to identify any associations between the microbial content of the samples, as well as potential health effects.
Functional Immune: Over the weekend and today two 52S crewmembers continued to support a five-day Functional Immune session that began Friday by collecting saliva samples. The samples support the return minus zero day (R-0) compliment for the 52S crewmembers. The crew will also perform a dry saliva collection using the Saliva Collection Dry Book. The Functional Immune investigation analyzes blood and saliva samples to determine the changes taking place in crewmembers’ immune systems during flight. The changes in the immune system are also compared with crewmembers’ self-reported health information. Results are expected to provide new insight into the possible health risks of long-duration space travel, including future missions to Mars, asteroids, or other distant destinations.
Veg-03 Operations: The crew performed Veg-03 operations by watering each plant pillows and photo documenting the progression of the plant grow outs. The overall goal of Veg-03 is to further demonstrate proof-of concept for the Veggie plant growth chamber and the planting pillows. Future long-duration missions into the solar system, finally culminating on Mars, will require a fresh food supply to supplement crew diets, which means growing crops in space. Previous investigations focused on improving productivity in controlled environments, but the limited quarters of the space shuttle and International Space Station made it difficult to conduct large-scale crop production tests. Veg-03 expands on previous validation tests of the new Veggie hardware, which crew members will soon use to grow cabbage, lettuce and other fresh vegetables in space.
Device for the study of Critical Liquids and Crystallization (DECLIC): The crew removed the Directional Solidification Insert (DSI) from the DECLIC Experiment Locker (EXL), before installing and activating the ALICE-LIKE Insert (ALI) in the EXL. The crew also removed and replace the removable hard disk drive inside the EXL. DECLIC is a multi-user facility utilized to study transparent media and their phase transitions in microgravity onboard the International Space Station (ISS).
At Home in Space: The crew took photographs to document ISS culture. This Canadian Space Agency investigation assesses culture, values, and psychosocial adaptation of astronauts to a space environment shared by multinational crews on long-duration missions. It is hypothesized that astronauts develop a shared space culture that is an adaptive strategy for handling cultural differences and they deal with the isolated confined environment of the spacecraft by creating a home in space. At Home in Space also uses questionnaires to investigate individual and culturally related differences, family functioning, values, coping with stress, and post-experience growth.
Earth Imagery from ISS Target (EIISS): Over the weekend, the crew used the Nikon camera to capture images of South Australia and Tasmania. Today, the crew captured Australia at night using the light from the moon and took images of the Australia Desert, the Southern tip of India, the USA East Coast and Ireland during the day. 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.
Remote Power Controller Module (RPCM) Removal and Replace (R&R) – Today, the crew successfully R&Red RPCM N13B_A using the Hot Mate/Demate technique. This is the second Intra-Vehicular Activity (IVA) RPCM Hot Mate/Demate replacement performed on-orbit, made possible by the updated firmware load which increases the boot delay time to 3 minutes. Following the crew activity, ground teams recovered power to the External Stowage Platform -1 (ESP-1) Primary Heaters. Power to these heaters was lost due to a trip in October 2017.
LAB1P1 Rack Flow Control Assembly (RFCA) Reconfiguration – Today, the crew relocated the LAB1P1 Internal Thermal Control System (ITCS) rack Bypass Jumper from the Moderate Temperature Loop (MTL) to the Low Temperature Loop (LTL). This reconfiguration places the MTL ITCS lines on the RFCA to allow MTL rack flow control, which is required to support the Life Support Rack arriving on HTV-7 later this year. The Lab ITCS was transitioned to Dual Loop Mode during the activity to mitigate impacts in the event of a water leak.
