SpaceX-6(SpX-6) Status:  Dragon has successfully completed several burns today on its way to station.  Cristoforetti and Virts are scheduled to capture Dragon tomorrow morning at approximately 06:00 CDT.   Space Aging and Nematode Muscle Familiarization: Kelly reviewed overview messages on 2 JAXA experiments currently onboard SpX-6.  Both experiments will study the impacts of the zero-gravity environment on C. elegans roundworms.  In Alterations of C. elegans muscle fibers by microgravity (Nematode Muscles), investigators hope to clarify how and why these changes take place in microgravity. Studying worms exposed to both microgravity, and gravity-like conditions in a centrifuge, could help scientists understand the molecular mechanisms responsible for muscle atrophy and other spaceflight-induced changes.  In the Study of the Effects of Spaceflight on the Aging of C. elegans (Space Aging), the crew will grow millimeter-long C. elegans roundworms in microgravity and compare their health and longevity with control specimens on Earth.  Both experiments will be incubated in the JAXA Cell Biology Experiment Facility (CBEF). The Effect of Long-Term Microgravity Exposure on Cardiac Autonomic Function (Biological Rhythms): Kelly continued his 48-hour data collection using Holter Electrocardiogram (ECG).  This morning, he completed the first 24-hour collection then exchanged the memory card and battery and started the next 24-hour collection. Biological Rhythms 48 hours studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. While space station keeps Greenwich Mean Time (GMT), it remains unknown whether a separate biological rhythm is imposed on long-term flight crews. To study this astronauts wear an Actiwatch sleep monitor for 96 hours and a Holter electrocardiograph for 48 hours in the middle of that sequence. Russian Joint Research (RJR) Microbial Air Sampler (MAS) and Surface Sample Kit (SSK) Sampling: Padalka is currently taking air samples and will later take surface samples (fungal and microbial) in modules throughout the ISS. These samples will be incubated and analyzed on Tuesday, April 21. The investigation refines locations and surfaces prone to microbial contamination throughout the ISS, shares monitoring technologies and data between NASA and Roscosmos, and provides a scientific basis for decisions about future microbial monitoring, both on ISS through its extended life, and on other future human exploration spacecraft. Dragon Robotics On-Board Trainer (RoBOT) On-Board Training (OBT): In preparation for tomorrow’s capture and berthing of the Dragon vehicle, the USOS crew conducted the second session of this training. They completed 2 Capture Point (CP) Hold runs which allows practice free drift timing, malfunction resolution and nominal rate approaches. They also practiced 2 meter approaches. Following the training, the crew reviewed Dragon attached phase operations. Centerline Berthing Camera System (CBCS): Virts installed the CBCS and all related avionics for Dragon mating at Node 2 Nadir. He performed a video system checkout by routing CBCS to the Robotic Work Station (RWS) and Ground, then powered down prior to removing the CBCS.

The Effect of Long-Term Microgravity Exposure on Cardiac Autonomic Function (Biological Rhythms): Kelly set up and donned a Holter Electrocardiogram (ECG).  He will record his ECG data for 48 hours, synching and downlinking the data between 21 and 24 hours after starting.  Biological Rhythms studies the effects of long-term microgravity exposure on heart function by analyzing an astronaut’s electrocardiogram for 48 hours. While ISS keeps Greenwich Mean Time (GMT), it remains unknown whether a separate biological rhythm is imposed on long-term flight crews. To study this, astronauts wear an Actiwatch sleep monitor for 96 hours and a Holter electrocardiograph for 48 hours in the middle of that sequence. Circadian Rhythms: Cristoforetti configured the Circadian Rhythm Armband Monitor and donned the Thermolab sensors and belt.  She will wear the Circadian Rhythm monitors for 36 hours then doff and download the data on Friday.  The objective of the Circadian Rhythm experiment is to obtain a better understanding of any alterations in circadian rhythms in humans during long-duration spaceflight.  Such knowledge will provide important insights into the adaptations of the human autonomic nervous system in space over time, and has significant practical implications by helping to improve physical exercise, rest- and work shifts as well as fostering adequate workplace illumination in the sense of occupational healthcare in future space missions.  The Circadian Rhythms will be measured by monitoring the bodies core temperature. During the first, mid and last session, the armband system will also be used. Node 3 (N3) Forward Midbay Intermodule Ventilation (IMV) Reconfiguration: Following yesterday’s procedure review and hardware gather, Cristoferetti removed existing IMV hardware from N3 Forward Midby and installed new ducting and an IMV Manual Valve in preparation for the PMM relocate to N3 Forward. Extravehicular Activity (EVA) Hard Upper Torso (HUT) Swap: Yesterday the crew moved Extravehicular Mobility Unit (EMU) 3011 from the Forward EMU Don/Doff Assembly (EDDA) to the Crewlock and EMU 3005 from the Crewlock to the Forward EDDA. Today Virts and Kelly swapped HUTs between EMU 3005 (size XL) and EMU 3010. This results in EMUs 3003 (size L) and 3010 (size XL) as primary EMUs with 3005 as backup.  Following the HUT swap the crew performed a successful EMU checkout of both 3005 and 3010 Today’s Planned Activities All activities were completed unless otherwise noted.

SpaceX (SpX-6) Launch: Dragon successfully launched today at 3:10 PM CDT. Capture is planned for Friday April 17th at ~6:00 AM CDT. European Modular Cultivation System (EMCS) Rotor Based Life Support System (RBLSS) and Water Reservoir Removal:  Cristoforetti successfully removed all four EMCS RBLSS Modules and two Water Reservoirs and packed them for return on SpaceX-6 (SpX-6).  The next planned use of EMCS is either the NASA experiment Plant RNA Regulation on SpX-8 or the ESA experiment Seedling Growth-3, currently manifested for SpX-9.  The RBLSS and Water Reservoir removal activities are routine maintenance and will be refurbished once returned to the ground. Kubik 6 Data Download: Following the successful completion of the Stem Cell Differentiation experiment, Cristoforetti copied the data from Kubik 6 to the European Drawer Rack (EDR) Laptop and then transferred the data to a Station Support Computer (SSC) for subsequent downloading to the ground for evaluation.  Stem Cells play a major role in the maintenance of bone mass, being the main source of osteoblasts during the bone remodeling and repair. The recruitment of an adequate number of osteoblasts is dependent on the availability of human Mesenchymal Stem Cells (hMSCs) and their proper response to growth, differentiation, and chemotactic signals in the microenvironment. This investigation aims at understanding how human mesenchymal stem cells react to a two week exposure to microgravity in terms of growth, senescence and differentiation towards osteoblasts when treated with Vitamin D3.  Spaceflight Effects on Neurocognitive Performance: Extent, Longevity, and Neural Bases (Neuromapping): Kelly performed his first inflight session of Neuromapping.  He configured the workstation and executed the Mental Rotation I Test, the Sensorimotor Adaptation Test, and the Dual Task Test while tethered, and the Mental Rotation II Test while free-floating.  NeuroMapping studies whether long-duration spaceflight causes any changes to the brain, including brain structure and function, motor control, and multi-tasking; as well as measuring how long it takes for the brain and body to recover from those possible changes. Previous research and anecdotal evidence from crewmembers returning from a long-duration spaceflight suggests that movement control and cognition are affected in microgravity. The NeuroMapping investigation utilizes structural and functional magnetic resonance brain imaging (MRI and FMRI) to assess any changes to crewmembers after a six-month mission on the International Space Station.  Payload On-orbit Still Shots for Utilization and Maintenance (POSSUM) Photography: Virts photographed the payload racks.  The images were downlinked and will be used for crew training and rack configuration confirmation.  Habitability Video Walk-Through: Kelly recorded a video, documenting observations using the iSHORT application, providing insights related to human factors and habitability.  Today’s video was of the hygiene areas onboard the ISS.  Habitability assesses the relationship between crew members and their environment in order to better prepare for future long-duration spaceflights to destinations, such as Near Earth Asteroids (NEA) and Mars. The ultimate goal is to understand how much habitable volume is required for vehicle internal design and layout, and if mission duration impacts the volume needed. Observations during the 1-year mission, as well as 6-month missions, can help spacecraft designers understand how much habitable volume is required, and whether a mission’s duration impacts how much space crew members need.  The iShort application will enable ground support teams and human factor engineers to study and evaluate the design of the ISS and use these results for future spacecraft. Combustion Integration Rack (CIR) Fuel Oxidizer Management Assembly (FOMA) Calibration Part 1: Kelly started the first part of the CIR FOMA calibration today.  He open the upper rack door, closed the bottle valves, relived the pressure in the manifolds, and closed the upper rack door. The Flight Calibration Unit (FCU) was used to collect pressure transducer data with the bottle pressure transducers at ambient pressure.  The FOMA calibration is part of CIR nominal maintenance.  The next use of CIR will be the FLame Extinguishment Experiment-2 JAXA (FLEX-2J) experiment. Node 3 (N3) Forward Midbay Intermodule Ventilation (IMV) Reconfiguration: Cristoferetti reviewed procedures for reconfiguration of N3 forward IMV hardware to provide IMV to the N3 forward berthing port in preparation for Permanent Multipurpose Module (PMM) relocation. She also gathered equipment for the reconfig task scheduled for tomorrow. Extravehicular Activity (EVA) Hard Upper Torso (HUT) Swap Preparation: Virts and Kelly moved EMU 3011 from the Forward EMU Don/Doff Assembly (EDDA) to the Crewlock, then moved EMU 3005 from the Crewlock to the Forward EDDA.  This activity was in preparation for tomorrow’s HUT swap between Extravehicular Mobility Unit (EMU) 3005 (size XL) and EMU 3010. This will result in EMUs 3003 (size L) and 3010 (size XL) as primary EMUs with 3005 as backup. A new EMU 3017 (size M) is scheduled to arrive on SpX-7. Node 1 (N1) 1553 Portable Computer System (PCS) Jumper Checkout: The crew performed a successful checkout of the N1 1553 PCS jumpers which connect to the primary Node 1 Multiplexer Demultiplexer (MDM) via the UB-ORB-N1 buses, this jumper would be used in the event all 3 Command & Control (C&C) MDMs failed or were unavailable. The checkout included a connectivity check to ensure the PCS would connect to the N1 MDM, as well as functionality checkout of the PCS connected to the Node Control Software (NCS).

Ocular Health: Virts and Cristoforetti completed their Return-30 day (R-30) Ocular Health activities today. They each performed ocular ultrasounds and Virts performed a cardiac ultrasound.  This week’s Ocular Health sessions were shared payload and medical requirements.  Ocular Health protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines. Human Research Program (HRP) Collections: Kelly collected blood, urine, and cheek swab samples in support of Biochemical Profile, Twins Study, and Cardio Ox experiments.  Following collection, samples were inserted into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). 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. Twins Study is an integrated compilation of ten different studies led by multiple PI’s at multiple centers.  The studies take advantage of a very unique opportunity to look at the effects of space travel on identical twins, one of whom experiences space travel for one year; the other mains earth-bound for that same year.  The study looks at changes in the human body in the fields of genetics, psychology, physiology, microbiology, and immunology. Cardio Ox is to determine whether biological markers of oxidative and inflammatory stress are elevated during and after space flight and whether this results in an increased, long-term risk of atherosclerosis in astronauts. Crew members provide blood and urine samples to assess biomarkers before launch, three sessions while in space, and again post-flight. Ultrasound scans of the carotid and brachial arteries will be obtained at the same time points, as well as through 5 years after landing as an indicator of cardiovascular health. Integrated Resistance and Aerobic Training Study (Sprint) Volume of Oxygen Utilized (VO2) Exercise Session:  Kelly performed his Sprint exercise session on the Cycle Ergometer with Vibration Isolation and Stabilization (CEVIS).  He donned Electrocardiogram (ECG) electrodes, Heart Rate Monitor (HRM) hardware, and Portable Pulmonary Function System (PPFS) calibrations, then executed the VO2 protocol.  The Sprint investigation evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in ISS crewmembers during long-duration missions. Upon completion of this study, investigators expect to provide an integrated resistance and aerobic exercise training protocol capable of maintaining muscle, bone and cardiovascular health while reducing total exercise time over the course of a long-duration space flight. This will provide valuable information in support of investigator’s long term goal of protecting human fitness for even longer space exploration missions. SpaceX-6 (SpX-6) Preparations: Today, the Robotics Ground Controllers powered up the Mobile Servicing System (MSS) on the Prime String and performed the Space Station Remote Manipulator System (SSRMS) Brake and Joint Diagnostics and Latching End Effector (LEE)-B Checkout and Setup.  Next they powered up the MSS on the Redundant String and repeated the SSRMS Brake and Joint Diagnostics and LEE-B Checkout and Setup.  The Robotics Ground Controllers then maneuvered the SSRMS such that the S1 Lower Outboard Camera could be used to verify that the LEE-B Snare Cables were correctly configured.  These activities were performed to check out the SSRMS in preparation for the capture of the SpX-6 Dragon on GMT 105 (15 Apr 15).  The Robotics Ground Controllers then maneuvered the SSRMS to the SpaceX High Hover position and are currently supporting the Visiting Vehicle Officer Robotic Workstation (RWS) camera calibration and overlays camera zoom test.  MSS performance today so far has been nominal. Node 3 (N3) Carbon Dioxide Removal Assembly (CDRA) Fault and Recovery: This morning the N3 CDRA faulted due to Air Selector Valve (ASV) 106 not transitioning between valve positions at the expected rate. Following the fault, ground teams individually commanded ASV 106 to move between valve positions. The commanding to ASV 106 was successful. N3 CDRA was recovered and is currently performing as expected. ASV 106 was replaced on March 24th, 2015. There are 2 spare ASVs available on board. Compound Specific Analyzer-Combustible Products (CSA-CP) Checkout:  During this morning’s CSA-CP checkout of the units that arrived on 42S the crew reported parameters still out of range.  The crew has re-stowed the units to continue off-gassing before deploying the units for operations.  Today’s Planned Activities All activities were completed unless otherwise noted.
