Advanced Combustion via Microgravity Experiments (ACME): The crew replaced the Combustion Integrated Rack (CIR) manifold bottles this morning. To prepare for the second part of the CLD Flames investigation the crew configured the ACME Chamber Insert, replaced the igniter tip, and replaced two ACME controllers. The ACME experiment series being performed in the CIR includes five independent studies of gaseous flames. The primary goals of ACME are to improve fuel efficiency and reduce pollutant production in routine fuel combustion activities on Earth. Its secondary goal is to improve spacecraft fire prevention through innovative research focused on materials flammability.

Kubik 6: The commissioning for ESA’s Kubik 6 facility continued today. The crew set up the Kubik 6 in the Columbus module, adjusted the sensor signal and calibrated the temperature sensors. They then installed the Foam Carriers in Kubik 6. Kubik is a small controlled-temperature incubator or cooler used to study biological samples in a microgravity environment. It is equipped with removable inserts designed for self-contained, automatic experiments using seeds, cells, and small animals.

Atomization: Today the crew set up and activated Atomization hardware in the Multi-purpose Small Payload Rack (MSPR). The Atomization experiment investigates the disintegration processes of a low-speed water jet for various jet issue conditions in the Japanese Experiment Module (JEM) to validate the new atomization concept by observing the process using a high speed camera. The knowledge gained can be applied to improve various engines utilizing spray combustion.

Human Research Program (Biochemical Profile, Marrow, Vascular Echo, and Repository): 53S crewmembers collected urine samples for their Return minus 14-day session of the Biochem Profile, Marrow, Vascular Echo and Repository investigations. Collecting of blood samples has been delayed because of an issue with activating the Refrigerated Centrifuge (RC). The alternate centrifuge will be used. Troubleshooting plans are in work by the team. A 54S crewmember collected urine samples for his Flight Day 60 session of the Biochem Profile and Repository investigations.

The Biochemical Profile investigation 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.

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.

Vascular Echo 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.

Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. The 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.

NeuroMapping: A 53S crewmember set up the Neuromapping hardware today and performed his Flight Day 150 tests in “strapped in” and “free floating” body configurations. The NeuroMapping investigation studies whether long-duration spaceflight causes changes to brain structure and function, motor control, and multi-tasking abilities. It also measures how long it takes for the brain and body to recover from possible changes. Previous research and anecdotal evidence from astronauts suggests movement control and cognition can be affected in microgravity. The NeuroMapping investigation includes use of structural and functional magnetic resonance brain imaging (MRI and fMRI) to assess any changes that occur after spending months on the ISS.

OA-9 Robotics Onboard Training: Today the crew scheduled to capture OA-9 performed a second Robotics Onboard Trainer (ROBoT) session a reviewed their Cygnus Attached Phase procedures. ROBoT is an on-orbit version of the ground-based Dynamics Skills Trainer (DST) that simulates robotics operations with graphical feedback.

Extravehicular Activity (EVA) Preparations: Today the crew conducted Extravehicular Mobility Unit (EMU) maintenance and EVA tool configurations in preparation for the upcoming US EVA #51 Node 2 EWC. Following the EMU Cooling Loop Scrubs, the crew took water samples from the cooling loops, performed and iodination of EMU Ion Filters, and tested the water samples for conductivity. The Node 2 EWC EVA is currently planned for June 14th.

Public Affairs (PAO) Live Event: Today Arnold and Tingle participated in a live PAO event with the Vaughn Next Century Learning Center in San Fernando, California. The audience for this event consisted of student representatives from all grade levels and ages across Vaughn’s TK-12 span and Science, Technology, Engineering and Math (STEM) programs.
