ISS Daily Summary Report – 3/14/2018
 

Veg-03:  Today the crew watered the Veg-03 plants and continued with the photo-documentation of plant growth for the Veg-03 investigation. Veg-03 supports the proof-of concept for the Veggie plant growth chamber and the planting pillows. Future long duration space missions will require a fresh food supply grown in space to supplement crew diets.

Earth Imagery from ISS Target (EIISS): Today the crew captured images of the area from southern California to the Baja peninsula for the Earth Imagery investigation.  EIISS captures a series of videos showcasing targets around the world as seen from the ISS. These videos will be integrated into a product for later release.

Meteor: The crew performed a routine changeout of the hard drive in the Meteor laptop located in the Window Observational Research Facility (WORF).  The Meteor payload uses a visible spectroscopy instrument to observe meteors in Earth orbit and then analyze the images to provide information on the physical and chemical properties of meteoroid dust. The study of the meteoroid dust on-orbit provides information about the parent comets and asteroids.   

On-Board Training (OBT) 53 Soyuz (53S) Emergency Egress Drill:  All three crew members participated in a training session when they reviewed and practiced procedures that would be performed in the event of an emergency that required the crew to egress ISS and execute an emergency descent. This drill is scheduled after the crew has been onboard for 12 to 14 weeks and every 2.5 months thereafter.

Extravehicular Activity (EVA) Airlock Unstow: In preparation for US EVA #49 at the end of the month, the crew relocated hardware not needed for the upcoming EVA and prepared the Airlock to support EVA operations.

MetOx Regeneration Initiation:  Today the crew initiated a MetOx regeneration cycle on 2 MetOx canisters. This process is expected to take 14 hours and the crew is scheduled to terminate the regeneration cycle and remove the canisters from the MetOx Regenerator on Friday.  These two canisters will be used during an upcoming EVA.

Eye Exams: Today the crew completed routine eye exams using an Ultrasound machine. Eye exams are performed regularly onboard in order to monitor crewmembers eye health.  Eyesight is one of the many aspects of the human body that is affected by long-duration stays in a microgravity environment.

Progress 69P ISS Reboost: Last night the ISS performed a nominal reboost using the 69P thrusters.  The purpose of the reboost was to start phasing for 53S landing in June and 70P 2-orbit constraints in July.  The reboost time of ignition (TIG) was 072/21:25:00 GMT (Tuesday, March 13, 04:25:00 pm CDT), with a burn duration of 1 m 48 s.

Remote Power Control Modules (RPCM) P14B-G and P13A-G Swap:  In July 2017 RPCM P14B-G Remote Power Controller (RPC) 11, which powers the thermostatically controlled Port Thermal Radiator (PTR) Multiplexer/Demultiplexer MDM survival heaters, tripped due to a hybrid Field Effect Transistor (FET) failure.  To regain functionality of the heaters, later today ground robotic specialist will use the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) to swap RPCM P14B-G and P13A-G.  Since there is no load downstream of RPCM P13A-G RPC 11 there will be no impact of this hybrid FET failure following the swap.

ISS Daily Summary Report – 3/15/2018
 

Remote Power Control Modules (RPCM) P14B-G and P13A-G Swap:  Ground robotic operations using the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) to perform a swap of RPCM P14B-G and P13A-G continue. The installation of the new RPCM P14B-G was successful; however, the ground team was unable to fully seat the RPCM in the P13A-G location within operational time constraints. The SPDM, along with RPCM for the P13A-G location, was backed away from the work site. The specialists are planning to re-attempt the installation overnight tonight. The RPCM installed in the P14B-G location has been powered up, and RPC 11, feeding the PTR MDM survival heaters, was successfully closed recovering the survival heaters functionality.

Two Phase Flow (TPF): Today the crew deactivated the TPF experiment equipment in the Multi-Purpose Small Payload Rack (MSPR) for the experiment run completed overnight, adjusted the MSPR valve setting and then reactivated the equipment for a four-day experiment run that begins tonight. The Two-Phase Flow experiment investigates the heat transfer characteristics of flow boiling in the microgravity environment. This experiment provides a fundamental understanding of the behaviors of bubble formation, liquid-vapor flow in a tube, and how heat transfers in cooling systems. Two-phase flow employs a sample cooling loop using perfluorohexane, often used in coolants for electronics, to establish flow rate and heating power in different conditions.

Manufacturing Device (MD): The crew removed and stowed a 3D printed item from the Manufacturing Device today.  They also cleaned the extruder nozzle in preparation for subsequent MD prints.  The Manufacturing Device supports the production of components on the ISS for both NASA and commercial objectives. It is capable of producing parts out of a wide variety of thermopolymers including engineered plastics.

NeuroMapping: A 53S crewmember set up the Neuromapping hardware today and performed their Flight Day 90 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.

Lighting Effects:  Today a crewmember set up the Actiwatch hardware to prepare for a two week sleep study session that starts today and will include the time of crew sleep shifting prior to the arrival of the 54S vehicle on March 23rd. The Actiwatch and sleep logs will be used to track the crewmember’s 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.

JEM Airlock (JEMAL): Today the crew reconfigured the JEM ORU Transfer Interface (JOTI) in support of upcoming Materials ISS Experiment – Flight Facility (MISSE-FF) payload operations.  MISSE-FF will be a permanent external platform on the ISS that is modular and robotically serviceable. Remotely controllable sample carriers will provide sample protection and on-demand picture data previously unavailable on prior experiments.  Sample plates containing a variety of surface materials will be exposed to the space environment outside the ISS for varying durations to inform satellite designers on how different materials degrade over time.  MISSE-FF is currently manifested on SpaceX-14.

Eye Exams: Today the crew completed the second day of routine eye exams using Optical Coherence Tomography (OCT) and a Fundoscope. Eye exams are performed regularly onboard in order to monitor crewmembers eye health.  Eyesight is one of the many aspects of the human body that is affected by long-duration stays in a microgravity environment.

Extravehicular Mobility Unit (EMU) Li-Ion Battery Data Logging: Today the crew initiated a charging Autocycle of two EMU Long Life Batteries (LLB). Over the course of three days, the Autocycle will both charge the batteries and capture battery health data. These two batteries will support the upcoming US EVA #49 scheduled for later this month.

Linguini SSC Service Pack: Overnight the MCC-H ground team will deploy the Linguini Space Station Computer (SSC) service pack. This service pack will add the 54S/55S crew accounts, software to support Pressure Management Device (PMD), migrate the Bigelow Expandable Aerospace Module (BEAM) laptop to ZBook, expand the SpaceX Vehicle Data Transfer capability, and add NextGen Printer software support.

ISS Daily Summary Report – 3/16/2018
 

Veg-03:  Today the crew watered the Veg-03 plants and harvested leaves from each plant.  The leaves will then be preserved and inserted into cold stowage for later return to the Earth. The remainder of the plants will be left to grow and sprout new leaves. Veg-03 supports the proof-of concept for the Veggie plant growth chamber and the planting pillows. Future long duration space missions will require a fresh food supply grown in space to supplement crew diets.

Mouse Stress Defense:  Today the crew set up a Glove Box in preparation for transfer of mice for the Mouse Stress Defense investigation after their arrival on the SpaceX-14 Dragon vehicle. Space flight brings an extreme environment with unique stressors. Microgravity provokes cellular mechanical stresses and perturbs cellular signaling, leading to reduction of muscle and bone density. To overcome these stresses, one of the promising strategies is to activate Nrf2, a master regulator of antioxidant pathway. Mouse Stress Defense investigates how Nrf2 contributes to effective prevention of space-originated stresses.

NanoRacks Rock Candy:  The crew continued the ongoing photo-documentation of each Rock Candy pouch, showing any visible sugar crystal growth in each. This investigation teaches students about the effects of microgravity on crystal formations using nearly identical flight kits flown and operated onboard the 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.

Space Headaches:  The crew completed the weekly questionnaire for the ESA Space Headaches investigation today. This investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission.

Lighting Effects: Upon waking, a 53S subject completed a daily sleep log entry 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.

Extravehicular Mobility Unit (EMU) Suit Maintenance: Following this week’s removal of EMU 3008 and installation of EMUs 3003 and 3010 on the Equipment Lock EMU Don/Doff Assembly, the crew performed routine maintenance on EMU 3003 and 3006 including a loop scrub and EMU water conductivity tests.  These tests are required to ensure proper function of the EMU water subsystem during this month’s US EVA.

Node 3 Major Constituent Analyzer (MCA) Inspection:  On GMT 60, the Verification Gas Assembly (VGA) was replaced on the Node 3 MCA. After the R&R, partial pressure readings were not as expected and handheld Portable Oxygen Monitor (POM) and Carbon Dioxide Monitor (CDM) readings confirmed the MCA was not producing reliable partial pressure readings. In order to troubleshoot potential causes of the data irregularities, the crew performed an inspection of interfaces manipulated during the R&R. Following the crew inspection activities, the ground performed an MCA zero calibration and began a Quest airlock rapid sample activity so that ground teams can assess the MCA sample data.

Remote Power Control Modules (RPCM) P14B-G and P13A-G Swap: Overnight, the ground robotic specialists, using the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM), completed the swap of RPCMs P14B-G and P13A-G. Both RPCMs are re-powered and the PTR MDM survival heaters are functional with the good RPC 11 in the P13A-G location.

ISS Daily Summary Report – 3/19/2018
 

Circadian Rhythms: Today, a crewmember began a three day European Space Agency (ESA) Circadian Rhythms experiment by donning the Thermolab Double sensors, which are to be worn for 36 hours.  The objective of the experiment is to get a better understanding of any alterations in circadian rhythms in humans during long-term space flights. Such knowledge will not only provide important insights into the adaptations of the human autonomic nervous system in space over time, but also 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.

Veg-03:  Today the crew watered the Veg-03 plants and harvested leaves from each plant. The leaves were then preserved and inserted into cold stowage for later return to the Earth. The remainder of the plants were left to grow and sprout new leaves. Veg-03 supports the proof-of concept for the Veggie plant growth chamber and the planting pillows. Future long duration space missions will require a fresh food supply grown in space to supplement crew diets.

Earth Imagery from ISS Target (EIISS): On Sunday, the crew captured images of the Aurora Borealis.  EIISS captures a series of videos showcasing targets around the world as seen from the ISS. These videos will be integrated into a product for later release.

Lighting Effects: Upon waking over the weekend and this morning, a 53S subject completed a daily sleep log entry 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.

Columbus Condensate Water Separator Assembly (CWSA) Maintenance: This morning, the crew inspected and cleaned the Columbus CWSA unit.  After the inspection was completed the crew Removed and Replaced (R&R) the CWSA Desiccant Module.

Temperature and Humidity Control (THC) Intermodule Ventilation (IMV) Flow Measurement:  As part of system health monitoring, the crew used a Velocicalc tool to measure the amount of airflow through selected ventilation inlets and outlets.  Today’s measurements were taken in the PMA1, Node1, Node 2, Node 3, and the Cupola.

EVA Tool Gather and Configuration: The crew gathered and configured tools and hardware for US Extravehicular Activity (EVA) 49: N3 Enhanced Wireless Communication (EWC) & Camera Port (CP) 8 and US EVA 50: Pump Flow and Control Subsystem (PFCS) Relocate.

Space Station Robotic Manipulator System (SSRMS) Operations:  Friday evening (GMT 075-076), the Robotics Ground Controllers powered up the Mobile Servicing System (MSS) and maneuvered Special Purpose Dexterous Manipulator (SPDM) Arm1 to stow Robot Micro Conical Tool 1 (RMCT1) on SPDM Tool Holder Assembly 1 (THA1). Then SPDM was reconfigured to use Arm2 to stow RMCT2 on SPDM THA2. Finally SSRMS was maneuvered as required to stow SPDM on Mobile Base System (MBS) Power Data Grapple Fixture (PDGF) #2. SSRMS was maneuvered to park positon. MSS performance was nominal.

ISS Daily Summary Report – 3/20/2018
 

Mouse Stress Defense:  Today the crew continued preparations for the Mouse Stress Defense investigation which will start after the arrival of mice on the SpaceX-14 Dragon vehicle. The crew reconfigured laptop cables and connected the Cell Biology Experiment Facility (CBEF) to a backup power source.  Space flight brings an extreme environment with unique stressors. Microgravity provokes cellular mechanical stresses and perturbs cellular signaling, leading to reduction of muscle and bone density. To overcome these stresses, one of the promising strategies is to activate Nrf2, a master regulator of antioxidant pathway. Mouse Stress Defense investigates how Nrf2 contributes to effective prevention of space-originated stresses. 

NanoRacks Vuze (One Strange Rock):  The crew opened all Cupola Window shutters this morning and deployed the NanoRacks Vuze Camera in the Cupola to record views for one full Earth rotation, including sunrise and sunset.  The mounted camera captures day-in-the-life style footage as the crew goes about their nominal tasks in the ISS. This is one of a series of videos recorded by the crew to be used in the “One Strange Rock” virtual reality educational series recorded for the National Geographic Channel. Each episode in the series will feature a different crew member and address different natural history and solar system topics, raising awareness of the space program and the Earth as a life-support system.

Manufacturing Device (MD):  The crew removed and stowed a 3D printed item from the Manufacturing Device today.  They also cleaned the extruder nozzle in preparation for subsequent MD prints.  The Manufacturing Device supports the production of components on the ISS for both NASA and commercial objectives. It is capable of producing parts out of a wide variety of thermopolymers including engineered plastics.

Combustion Integrated Rack (CIR): The crew removed and replaced manifold bottles today to support the ongoing microgravity combustion research operations in the CIR.  Testing for the ACME investigation is currently being performed in the CIR.  ACME includes a set of 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.

Lighting Effects: A 53S crewmember completed a daily sleep log entry this morning upon waking to record 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.

Extravehicular Activity (EVA) Preparations: In preparation for the Node 3 (N3) Assembly External Wireless Communications (EWC) EVA currently planned for March 29th, the crew initiated charging of the EVA Helmet Interchangeable Portable Light (EHIP), Pistol Grip Tool (PGT), Rechargeable EVA Battery Assembly (REBA) and EVA Camera D4 batteries and terminated a MetOx Regeneration cycle.

US Lab Major Constituent Analyzer (MCA) Orbital Replacement Unit (ORU)-2 Remove and Replace (R&R): Today the crew replaced the Lab MCA Mass Spectrometer (ORU 02) with the on-orbit spare. The previously installed ORU 02’s ion pump failed in April 2017. Replacing the mass spectrometer regains MCA capability onboard while the team continues to troubleshoot the unexpected readings coming from the Node 3 MCA following the Verification Gas Assembly replacement on March 1. The ground is in the process of activating the Lab MCA. They will then perform an up-to 72 hour dryout and calibration before data is considered to be within spec accuracies.

Common Communications for Visiting Vehicles (C2V2) Checkout: This morning, a checkout of the C2V2 system was performed in support of the Orbital-ATK Cygnus (OA-9) mission which will utilize the C2V2 system for approach and capture for the first time. The test verified command capability from MCC-H (Houston), MCC-D (Dulles for Orbital) and from on board via the Portable Computer System (PCS). Ground teams are reviewing the results of the checkout.
