Space Station Remote Manipulator System (SSRMS) 52 Soyuz (52S) Survey: Today, ground operators walked the SSRMS off to the Functional Cargo Block (FGB) and conducted a video survey of the exterior 52S prior to return. 52S will return CDR Alexander Misurkin, FE-3 Joe Acaba, FE-2 Mark Vande Hei to Earth early next week.
Carbon Dioxide Removal Assembly (CDRA) Blower Testing: Ground teams are continuing testing of CDRA blower speed capabilities in order to maximize carbon dioxide removal from the ISS atmosphere.
ExtraVehicular Activity (EVA) Battery Charging: Today the crew configured a lithium-ion battery charger and initiated an Extravehicular Mobility Unit (EMU) Long Life Battery (LLB) charge cycle. Data logging is required to extend the expiration date of the LLBs.
Veg-03: Over the weekend, the crew continued to perform Veg-03 operations by thinning out the plants to one plant per pillow and added water to the small plant pillows. 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.
Human Research Program (HRP) Collections (Biochemical Profile, Marrow, and Repository): Over the weekend, a 52S crewmember completed his breath and ambient air sample collections to support the Marrow experiment, and today he completed his return minus 14 day (R-14) blood, and urine sample collections to support the Biochemical Profile, and Repository experiments. The samples were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).
- Marrow looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.
- The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body.
- Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.
Sally Ride Earth Knowledge Acquired by Middle School Students (EarthKAM) Node 2 Setup and Activation: Yesterday, the crew setup and activated the payload components for EarthKAM in Node 2 for a week-long imaging session. Sally Ride EarthKam allows thousands of students to photograph and examine Earth from a space crew’s perspective. Using the Internet, the students control a special digital camera mounted on-board the International Space Station. This enables them to photograph the Earth’s coastlines, mountain ranges and other geographic items of interest from the unique vantage point of space. The team at Sally Ride EarthKAM then posts these photographs on the Internet for the public and participating classrooms around the world to view.
Microbial Tracking-2 (MT-2): A 52S subject completed saliva and body sample collections in support of 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.
Combustion Integrated Rack (CIR) Advanced Combustion via Microgravity Experiments (ACME) Igniter Replacement: The crew removed and replaced the damaged ACME igniter tip. CIR provides sustained, systematic microgravity combustion research and it houses hardware capable of performing combustion experiments to further research of combustion in microgravity. The ACME investigation is a set of five independent studies of gaseous flames to be conducted in the CIR. ACME’s primary goal is to improve 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.
Plant Gravity Perception Operations European Modular Cultivation System (EMCS): Today the crew removed the EMCS Maintenance Work Area (MWA) Rotor A and Rotor B cassettes. The cassettes were promptly placed in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The crew also replaced the EMCS Thermal Control System (TCS) cold spot sponge. 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.
Earth Imagery from ISS Target (EIISS): Using the RED camera, the crew captured images of the Iberian Peninsula and Italy along with the Nile River and Red Sea. 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.
Rodent Research 6 (RR-6): Today the crew prepared the habitats for stowing. The Rodent Research-6 (RR-6) mission uses mice flown aboard the International Space Station (ISS) and maintained on Earth to test drug delivery systems for combatting muscular breakdown in space or during disuse conditions. RR-6 includes several groups of mice selectively treated with a placebo or implanted with a nanochannel drug delivery chip that administers compounds meant to maintain muscle in low gravity/disuse conditions.
Vascular Echo Ultrasound Using Echo: Today, the crew attached the ECG Electrodes and Cable and performed two scanning activities with remote guidance from ground team. Near the end of the activity, the crew donned the Leg Cuffs and performed an ultrasound scan prior to disconnecting and temp stowing the EGC Cable. The crew left the Echo connected to allow ground team to remotely transfer data from the Echo unit to its External Hard Disk. Vascular Echo investigation examines changes in blood vessels, and the heart, while the crew members are in space, and then follow their recovery on return to Earth. The results could provide insight into potential countermeasures to help maintain crew member health, and quality of life for everyone.
Robotic Operations: Yesterday and overnight Robotic Ground Controllers powered up the Mobile Servicing System (MSS) and maneuvered the Special Purpose Dexterous Manipulator (SPDM) and the Space Station Remote Manipulator System (SSRMS) to unstow the Spare SSRMS Yaw Joint from SPDM Enhanced Orbital Replaceable Unit (ORU) Temporary Platform (EOTP) and stow it on External Stowage Platform 2 (ESP-2) site 5. Next they configured the SPDM for stow and stowed it on Mobile Base System (MBS) Power Data Grapple Fixture 2 (PDGF2). Finally the SSRMS was walked off Node2 and onto the Lab in preparation for the 52S survey.
