ISS Daily Summary Report – 10/13/2017

Posted on October 13, 2017 at 4:00 pm by HQ.
 

Advanced Nano Step Troubleshooting: Today the crew successfully completed troubleshooting operations by retrieving the Advanced Nano Step cartridge from the Solution Crystallization Observation Facility (SCOF) to access and adjust the position of the cell stage, due to movement issues during the sample observation.  JAXA’s Advanced Nano Step experiment investigates the relationship between impurity incorporation mechanisms and the quality of obtained protein crystals should be clarified for the progress to an “advanced” stage of the space utilization for structure-based drug design. In this mission, we observe the protein crystal growth surfaces of glucose isomerase crystals in space in the presence of various impurities with the use of a Michelson interferometer. In addition, we also clarify the crystal surface morphology on the molecular step level by using the laser confocal microscope. We evaluate the crystal quality of the returned crystals.

Lighting Effects:  A 51S crewmember completed a Visual Performance Test by stowing the hardware in their crewquarters, setting the light to the correct mode, turning all other light sources in the crew quarters off, and performing a Numerical Verification Test and a Color Discrimination Test. The completed tests will be photographed and downlinked. 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.

Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Hardware Configuration: To prepare for upcoming ACE-T6 operations, the crew configured the back of the optics bench for the LMM upgrades for confocal operations. The Light Microscopy Module (LMM) is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS).

Combustion Integrated Rack (CIR) Configuration for Advanced Combustion via Microgravity Experiments (ACME): The crew continued to conduct ACME insertion configurations that began earlier this week by setting the CIR valve timers to limit fuel and oxygen into the CIR combustion chamber. The crew also removed and replaced a CIR manifold bottle and a CIR absorber cartridge. 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 improved 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.

Device for the study of Critical Liquids and Crystallization) DECLIC Hose Relocation: Following last month’s hose relocation to troubleshoot the moderate temperature loop (MTL) flow issues to the DECLIC directional solidification insert (DSL), today the crew returned the DECLIC water supply and return hoses from the Lower Control Panel to the Upper Control Panel, and re-connected the GLACIER water supply and return hoses into the Lower Control Panel.  DECLIC is a multi-user facility utilized to study transparent media and their phase transitions in microgravity onboard the International Space Station (ISS). The DSI portion of the DECLIC multi-user facility experiment will study a series of benchmark experiments on transparent alloys that freeze like metals under microgravity onboard the International Space Station (ISS) using SCN (succinonitrile-a transparent organic substance in the liquid state that is used to study the phenomena related to solidification processes) based alloys. The DSI insert will be installed for the second run of the three series of DECLIC experiments.

Space Headaches:  The weekly questionnaire for the ESA Space Headaches investigation was completed by the crew.  The Space Headaches 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.

USOS Extra-Vehicular Activity (EVA) #46 Preparations:  Today the crew reviewed preliminary EVA procedures, conducted a conference with ground specialists, and charged batteries in preparation for next week’s EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the degraded CP13 camera and R&R of the Latching End Effector (LEE) A Camera Lens Assembly (CLA).

External Television Camera Group (ETVCG) Maintenance:  Today the crew performed maintenance procedures required to prep an ETVCG for future installation at Camera Port 13 (CP13). The ETVCGs provide external views of the station and provide enhanced situational awareness as well as views of the Earth from space.

Extravehicular Robotic Operations: Last night the ground controllers powered up and maneuvered the Space Station Remote Manipulator System (SSRMS) to grapple the Special Purpose Dexterous Manipulator (SPDM). SPDM Arm2 was used to unstow Robot Micro Conical Tool (RMCT) #2 from the Tool Holster Assembly (THA) and SPDM Arms and Body were configured in preparation for the Remote Power Controller Module (RPCM) P12B-B Remove and Replace activity.

ISS Daily Summary Report – 10/16/2017

Posted on October 16, 2017 at 4:00 pm by HQ.
 

68 Progress (68P) docking:  Saturday morning, 68P launched from Baikonur after a two day delay.  This morning, 68P docked successfully to DC1 nadir, bringing supplies to the ISS.

JAXA Protein Crystal Growth (PCG) #13 Installation:  Following the docking of 68P,  a crewmember stowed two canister bags containing protein samples in the JAXA Freezer-Refrigerator Of STirling cycle 2 (J-FROST2). This experiment will run from today through removal for return on Soyuz 51S.  The canisters contain protein samples prepared by Japanese and Russian researchers from universities, national research institutes, and the private sector. The purpose of this activity is to obtain high quality protein crystals in the microgravity environment at 20 degrees C for about 9 weeks. The results obtained by JAXA PCG #13 contribute to the development of drugs for multidrug-resistant bacteria, Alzheimer’s disease, muscular dystrophy and periodontitis. They will also aid in the development of a blood substitute and biosensor.

Advanced Nano Step Microgravity Measurements Apparatus (MMA) Cable Connection: After successfully adjusting the position of the cell stage to resolve movement issues during sample observations last week; today the MMA cable connection to the medical laptop was completed to measure MMA data during the Advanced Nano Step experiment run.  JAXA’s Advanced Nano Step experiment investigates the relationship between impurity incorporation mechanisms and the quality of obtained protein crystals should be clarified for the progress to an “advanced” stage of the space utilization for structure-based drug design. In this mission, we observe the protein crystal growth surfaces of glucose isomerase crystals in space in the presence of various impurities with the use of a Michelson interferometer. In addition, we also clarify the crystal surface morphology on the molecular step level by using the laser confocal microscope. We evaluate the crystal quality of the returned crystals.

Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 52S crewmember completed Flight Day (FD) 30 urine sample collections that began yesterday and blood sample collections in support of the Biochemical Profile and Repository experiments. The samples were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).
•The Biochemical Profile experiment tests blood and urine samples are 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.

Fine Motor Skills (FMS): A 51S crewmember completed a Flight Day 80 FMS session, where the subject performs a series of interactive tasks on a touchscreen tablet. The investigation studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compare with that of a closely matched participant on Earth; and how performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods.

USOS Extra-Vehicular Activity (EVA) #46 Preparations:  Today the crew configured tools, reviewed EVA procedures, and conducted a conference with ground specialists in preparation for next week’s EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the degraded CP13 camera and R&R of the Latching End Effector (LEE) A Camera Lens Assembly (CLA).

ISS Daily Summary Report – 10/17/2017

Posted on October 17, 2017 at 4:00 pm by HQ.
 

Miniature Exercise Device (MED-2):  Today crewmembers set up cameras in Node 3 to capture video from multiple views of the Advanced Resistive Exercise Device (ARED) and MED-2 hardware.  They also applied body markers, and performed exercises before transferring the video for downlink.  The ISS’s exercise equipment is large and bulky, while the MED-2 aims to demonstrate small robotic actuators can provide motion and resistance for crew workout sessions, reducing the size and weight of exercise equipment for long-duration space missions. The MED-2 investigation is a system to test key technologies needed to develop space based exercise equipment that may provide appropriate countermeasures to the adverse effects of microgravity. This technology is critical for the initial design and development of second and third generation Counter Measure Systems (CMS) hardware that is an order of magnitude lighter and smaller than existing ISS class of CMS hardware and that has significantly greater reliability.

Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Hardware Configuration: The crew continued to conduct the LMM configuration activities that began last week, by removing the Constrained Vapor Bubble (CVB) control box and LMM Monochrome camera, before installing the Fluids and Combustion Facility (FCF) high rate data link, the LMM confocal unit and brackets, and the LMM confocal and wide-field cameras. The LMM hardware configuration will support upcoming ACE-T6 operations. The Light Microscopy Module (LMM) is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS).

Meteor Grating Configuration: The crew removed and replaced gratings in the Meteor camera located in the Window Observational Research Facility (WORF) payload volume. The Meteor payload is a visible spectroscopy instrument with the primary purpose of observing meteors in Earth orbit. Meteor uses image analysis to provide information on the physical and chemical properties of the meteoroid dust, such as size, density, and chemical composition. Since the parent comets or asteroids for most of the meteor showers are identified, the study of the meteoroid dust on orbit provides information about the parent comets and asteroids.   

TangoLab-2 Card Troubleshooting: In August, during installation of a payload card into the TangoLab-2 slot, the card did not seat properly.  Today as part of the troubleshooting efforts, the crew took a different payload card from TangoLab-1 and then installed it into the slot in TangoLab-2. The crew photographed the inside of TangoLab-2 specifically where connectors are located for downlink.

Veg-03 Operations: The crew photo-documented the status of the plants in the Veggie facility. The Veg-03 investigation uses the Veggie plant growth facility to cultivate a type of cabbage, lettuce and Mizuna which are harvested on-orbit with samples returned to Earth for testing.  Organisms grow differently in space, from single-celled bacteria to plants and humans. Future long-duration space missions will require crew members to grow their own food, so understanding how plants respond to microgravity is an important step toward that goal. Veg-03 uses the Veggie plant growth facility to cultivate a type of cabbage, lettuce and Mizuna which are harvested on-orbit with samples returned to Earth for testing.

Earth Imagery from ISS Target Operations: The crew setup and configured the RED camera in the Cupola to capture video footage of New York City and the Nile Delta. The Earth Imagery from ISS investigation creates a series of videos, showcasing Earth from space. These videos will be taken with cameras on the International Space Station in 6K hi-resolution, then integrated into videos for screensavers for public enjoyment, exploration, and engagement.

USOS Extra-Vehicular Activity (EVA) #46 Preparations:  Today the crew set up cameras and reviewed robotics procedures/tools in preparation for this Friday’s EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the Latching End Effector (LEE) A Camera Lens Assembly (CLA).

Remote Power Controller Module (RPCM) P12B-B R&R:  Today, robotics ground controllers removed a degraded RPCM from external slot P12B-B and attempted to replace it with a functional unit from P13A-G. The installation of the new RPCM into P12B_B slot was unsuccessful this morning. Ground teams have backed off to a park position. Teams are discussing a forward plan. This RPC provides power to the S-band String 2 Transponder.

ISS Daily Summary Report – 10/19/2017

Posted on October 19, 2017 at 4:00 pm by HQ.

Circadian Rhythms:  Yesterday a crewmember instrumented themselves with Thermolab Double Sensors and mounted the Thermolab Unit to their belt, which began 36 hours of monitoring for the Circadian Rhythm investigation.  Circadian Rhythms investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crew members’ circadian clocks. The investigation also addresses the effects of reduced physical activity, microgravity and an artificially controlled environment. Changes in body composition and body temperature, which also occur in microgravity, can affect crew members’ circadian rhythms as well. Understanding how these phenomena affect the biological clock will improve performance and health for future crew members.

Fine Motor Skills (FMS): Today a 51S crewmember completed a Flight Day 85 FMS session which was executed on a touchscreen tablet, where the subject performs a series of interactive tasks. The investigation studies how fine motor skills are affected by long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity. The goal of FMS is to answer how fine motor performance in microgravity trend/vary over the duration of a six-month and year-long space mission; how fine motor performance on orbit compares with that of a closely matched participant on Earth; and how performance trends/varies before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate post-flight periods.

Space Headaches:  The crew completed the weekly questionnaire for the ESA Space Headaches investigation. The Space Headaches 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.

USOS Extra-Vehicular Activity (EVA) #46 Preparations:  Today the crew conducted a review of EVA procedures and a conference with ground teams.  They also inspected tethers, configured tools, printed cuff checklists, and prepared the equipment lock in preparation for tomorrow’s EVA. The goals of USOS EVA #46 include Removal and Replacement (R&R) of the Latching End Effector (LEE) A Camera Lens Assembly (CLA).

Tablet Updates:  As part of the ongoing efforts to update the operating system on the onboard tablets, the crew performed steps to update and configure those tablets.

Remote Power Control Module (RPCM) P12B-B R&R:  Wednesday morning, ground teams completed the robotic activities to swap RPCM P12B-B with P13A-G.  On Monday night RPCM P12B-B was extracted and installed into empty truss slot P11A-D and the replacement RPCM was removed from slot P13A-G, however it could not be inserted into the P12B-B at that time.  Robotics activities resumed on Tuesday afternoon and teams were able to successfully install the replacement RPCM in the P12B-B slot after 47 wiggle and push attempts.  The new P12B-B RPCM powered up nominally.  Ground teams then removed the failed RPCM from the P11A-D truss slot and relocated it to the P13A-B slot successfully.  The power up of the P13A-G RPCM was also performed nominally.  This completes the RPCM swap activities.

JEM Airlock (A/L) Reconfiguration:  Today, the crew removed the MBSU from the JEM A/L where it had been stowed after the I-Level maintenance was performed in early September.  The Kaber plate and adapter plate were then installed on the A/L slide table in preparation for installation of the KE2M satellite on Monday.  After KE2M and SIMPL, another JEM A/L-deployed satellite, are deployed next week, the MBSU will be returned to the JEM A/L for transfer and installation externally at External Stowage Platform 2 (ESP2).

External Robotics Operations:  Overnight, robotics ground controllers stowed the Special Purpose Dexterous Manipulator (SPDM) and configured the SSRMS to be in position for the EVA tomorrow.  The SSRMS is now based on LEE B, at Mobile Base System (MBS) Power Data Grapple Fixture 4 (PDGF), Worksite 6. LEE A is ready to receive a new LEE CLA.

International Space Station Crew Invites Public Along for Photographic Trip Around World

NASA astronaut and Expedition 53 Commander Randy Bresnik will spend one full orbit photographing Earth from the International Space Station on Monday, Oct. 23, and he is inviting people around the globe to share images from their Earth-side vantage point on social media.

Bresnik, with help from fellow astronaut Joe Acaba, will begin the “photo frenzy” from the station’s 360-degree Earth-facing cupola window beginning at 8:25 a.m. EDT. Traveling at about five miles per second, the station completes one orbit around Earth approximately every 90 minutes.

As part of NASA’s Year of Education on Station, an initiative to inspire more students and teachers than ever before during the 2017-18 school year, students located in areas Bresnik will photograph are especially invited to join him on the journey and share their photos, including their locations and names of their schools.

“You can’t look at the Earth and not be changed,” Bresnik said. “You realize every experience you’ve ever had and every person you’ve ever known is down on that little blue marble.”

The station’s orbit will begin with a sweep from the United Kingdom across central Europe to Oman, a pass near the Maldives, sunset west of Australia and sunrise over the south Pacific Ocean before concluding with a pass over North America from Puerto Vallarta, Mexico, to Montreal, Canada. Bresnik will be posting updates of his views on his social media accounts throughout, as satellite communications coverage allows.

Regardless of where you’ll be on Earth during their photo session, the astronauts are asking for your help to capture this moment in time, specifically from 8:25-9:55 a.m. EDT (12:25-13:55 GMT). They’re encouraging educators, students, and the public to post a picture to social media of their surroundings from their unique vantage point using the hashtag #1World1Orbit.

Astronaut photography documents how the planet changes over time, from human-caused changes like urban growth and reservoir construction, to natural dynamic events such as hurricanes, floods and volcanic eruptions. In addition to research applications, photography is a favorite pastime of the crew, and many astronauts feel compelled to share their cosmic perspective with humanity with humanity on social media.

There are opportunities for humanity to stay in touch with our representatives off the planet every day. You can track the station and sighting opportunities in your area anytime with NASA’s Spot the Station tool.

Another Earth observation from station opportunity is Sally Ride EarthKAM, which begins its next mission on Nov. 1, and allows student groups to track and analyze sections of the planet over time.

ISS Daily Summary Report – 10/20/2017

Posted on October 20, 2017 at 4:00 pm by HQ.
 

USOS Extra Vehicular Activity (EVA) #46:  Randy Bresnik (as EV1) and Joe Acaba (as EV2) successfully performed US EVA #46 with a Phased Elapsed Time (PET) of 6 hrs 49 min. The primary goals of the EVA were to Remove and Replace (R&R) a fuse in the Special Purpose Dexterous Manipulator (SPDM) Enhanced ORU Temporary Platform (EOTP), install an External High Definition Camera (EHDC) at the Camera Port 3 (CP3) location, and install a new Camera/Light Assembly (CLA) on the Space Station Remote Manipulator System (SSRMS) Latching End Effector A (LEE A). The crew also removed Multi-Layer Insulation (MLI) from an Main Bus Switching Unit (MBSU) and tied down an MLI Skirt on a spare Direct Current Switching Unit (DCSU). The crew also performed the following get ahead tasks: Lubrication of the LEE A Linear Bearings, Prep of two Pump Modules (PMs) by removing the MLI straps and tape used for launch loads, and T-Handle installation on the Port Radiator Grapple Bar (RGB).

Circadian Rhythms: The 51S crewmember removed and stowed the Double Sensors and Thermolab Unit equipment that was used to complete a 36 hour Circadian Rhythms session that began on Wednesday. Circadian Rhythms investigates the role of synchronized circadian rhythms, or the “biological clock,” and how it changes during long-duration spaceflight. Researchers hypothesize that a non-24-hour cycle of light and dark affects crewmembers’ circadian clocks. The investigation also addresses the effects of reduced physical activity, microgravity and an artificially controlled environment. Changes in body composition and body temperature, which also occur in microgravity, can affect crewmembers’ circadian rhythms as well. Understanding how these phenomena affect the biological clock will improve performance and health for future crewmembers.

Space Headaches:  Today a 51S crewmember completed a weekly questionnaire for the ESA Space Headaches investigation. The Space Headaches 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.
