South Carolina Students to Speak with NASA Astronaut on Space Station

Students at Laing Middle School in Mount Pleasant, South Carolina, which is near Charleston, will speak with a NASA astronaut living, working and doing research aboard the International Space Station at 10:20 a.m. EDT Friday, Sept. 8. The 20-minute, Earth-to-space call will air live on NASA Television and the agency’s website.

Expedition 52 Flight Engineer Col. Randy Bresnik is an alumnus of The Citadel, located in Charleston. He will answer questions from students at Laing Middle School. The school is hosting the event with the help of Citadel cadets and The Citadel STEM Center of Excellence. Cadets will lead the younger students as they pose questions to the Citadel astronaut alumnus.

Bresnik launched to the space station on July 28. He is expected to return to Earth in December. A Marine Corps veteran and member of The Citadel class of 1989, Bresnik is one of the college’s most visible principled leaders. In May of 2004, Bresnik was selected out of approximately 4,000 applicants to become one of the 11 members of NASA’s Astronaut Class 9, becoming the first graduate of The Citadel to have the opportunity to fly in space. Expedition 52/53 is Bresnik’s second mission to the space station, the first being in 2009. Bresnik is the commander of Expedition 53.

Media interested in covering the event should contact Kim Keelor at kkeelor@citadel.edu. Laing Middle School is at 2705 Bulrush Basket Lane in Mt. Pleasant.

The cadets will lead a two-part event for the eighth grade students, visiting the class first to teach them about Bresnik, the space station, how the live downlink works and conduct an in-class lesson related to the space station. On Sept. 8, they will lead the conversation with Bresnik, guiding the participating students as they ask questions that are expected to revolve around experiments which Bresnik is assisting, as well as space fitness. Middle school students across the South Carolina Lowcountry as well as cadets on The Citadel campus are expected to watch the event on NASA TV. A link to recording will be provided to other teachers wishing to show it in their classrooms.

Linking students directly to astronauts aboard the space station provides unique, authentic experiences designed to enhance student learning, performance and interest in science, technology, engineering and math (STEM). This in-flight education downlink is an integral component of NASA Education’s STEM on Station activity, which provides a variety of space station-related resources and opportunities to students and educators.

ISS Daily Summary Report – 9/06/2017

Posted on September 6, 2017 at 4:00 pm by HQ.
 

Venice Film Festival Public Affairs Office (PAO) Event:  Paolo Nespoli participated in a 20-minute ESA PAO event for the Venice Film Festival.  The documentary ‘Expedition’, which chronicles ESA Italian astronaut Paolo Nespoli’s preparation for human space mission, will be presented at the Venice Film Festival on September 6th. This PAO event was a press conference where journalists were given an opportunity to ask Paolo questions. The Director and producer of ‘Expedition’, Alessandra Bonavina, moderated the event.

Miniature Exercise Device (MED-2) Operations Session:  Today the crew continued to conduct the ARED portion of MED-2 operations that began earlier this week by using body markers and multiple floating camcorders to capture the crew performing dead lifts and rowing exercises. 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.

Genes in Space: The crew set up hardware in the maintenance work area (MWA) before conducting the Genes in Space experiment by processing the samples in the miniPCR, and then transferring the data to the SSC for downlink. The Genes in Space investigation, is a winning student-designed experiment, to test whether the polymerase chain reaction (PCR) can be used to study DNA alterations aboard the ISS. Spaceflight causes many changes to the human body, including alterations in DNA and a weakened immune system. Understanding whether these two processes are linked is important for safeguarding crew health, but DNA technology that can track these changes is relatively untested in space.

Electromagnetic Levitation (EML) European Drawer Rack (EDR) Maintenance: The crew performed maintenance activities by completing fan filter cleanings, rack rotations, and a handrail installation within the EML. EML is a facility composed of 4 inserts installed into the EDR on-orbit representing a facility for Electromagnetic Levitation of samples. The experiment samples are installed in a dedicated Sample Chamber that is attached to EML and will be replaced by new Sample Chambers for new experiment batches.

Space Automated Bioproduct Lab (SABL) Unit 2 Incubator Removal: Crewmembers removed a CO2 incubator controller from the SABL Unit 2 and then inserted ice bricks into SABL Unit 3 for conditioning. The SABL supports a wide variety of experiments in the life, physical and material sciences with a focus on supporting research of biological systems and processes. It has a temperature controlled volume with LED lighting for scientific hardware and experiments. It can be fitted to provide 5% CO2 for cell cultures.

ISS Daily Summary Report – 9/07/2017

Posted on September 7, 2017 at 4:00 pm by HQ.
 

MBSU I-Level Maintenance:  In early August, ground teams successfully transferred a degraded Main Bus Switching Unit (MBSU) from External Stowage Platform 2 (ESP2) site 4 to the JEM Airlock. Today, the crew removed the MBSU from the JEM A/L and performed Intermediate Level (I-Level) maintenance on the unit.  This MBSU is one of two failed units externally stowed on orbit that will be brought inside to undergo maintenance and repair.

Lighting Effects: This morning a crewmember provided a sleep log entry for the Lighting Effects investigation. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. Fluorescent bulbs are being replaced with solid-state light-emitting diodes (LEDs) that have adjustable intensity and color. Investigators will determine if the new lights improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have implications for people on Earth who use electric lights.

Light Microscopy Module (LMM) Camera Inspections: After completing routine inspections of the LMM Confocal Unit, LMM Confocal Camera, LMM Wide-field Camera, and the LMM Observation Camera for shattered materials, the crew reported that no damage was found to the equipment.  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). The LMM enables novel research of microscopic phenomena in microgravity, with the capability of remotely acquiring and downloading digital images and videos across many levels of magnification. The way that matter is organized and moves on the microscopic level profoundly affects the macroscopic world and an understanding of such processes helps scientists and engineers build more efficient materials and machines both for both the earth and space environments.

MAGVECTOR: The crew configured the power supply and supporting equipment prior to initiating the 13th experiment run of the MAGVECTOR investigation, which ends Thursday of next week.  MAGVECTOR investigates how Earth’s magnetic field interacts with an electrical conductor. Using extremely sensitive magnetic sensors placed around and above a conductor, researchers can gain insight into ways that the magnetic field influences how conductors work. This research not only helps improve future International Space Station experiments and electrical experiments, but it could offer insights into how magnetic fields influence electrical conductors in general, the backbone of our technology.

CAPCOM updated the US crew about solar flare activity being tracked by Houston.  There is no concern about radiation but the crew was advised of elevated locations in the orbit and areas of the station with more, and less, shielding.  On board sensors will alert the crew if necessary and CAPCOM will follow up with more details.
Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

ISS Daily Summary Report – 9/08/2017

Posted on September 8, 2017 at 4:00 pm by HQ.
 

Lighting Effects: The crew completed a visual assessment test in the Crew Quarters (CQs) by setting the light to the correct mode, turning all other light sources in the CQ off, and performing one Numerical Verification Test and one Color Discrimination Test. The crew will then photograph the completed tests, before transferring the photos for downlink. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. 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.

Multi-Omics-Mouse:  Today the crew performed routine maintenance operations by filling the transportation cage units with water and refilling the camera washer water of the Mouse Habitat Cage Unit located in the Cell Biology Experiment Facility (CBEF).  Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function.  After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis.

Rodent Research 9 (RR-9):  In support of the on-going RR-9 investigation, the crew restocked the Animal Habitat Units with new food bars and cleaned the lid and interior cages. RR-9 studies how microgravity affects the immune systems, muscles and bones of rodents during extended stays aboard the ISS.  After approximately 30 days aboard the ISS, the mice will be returned to Earth where scientists on the ground will study how their time in space has affected various tissues, including brain, muscle, heart, joints, eyes and the immune system.

MELFI (Minus Eighty Degree Laboratory Freezer for ISS) Electronic Unit Removal: While removing the failed spare Electronic Unit from MELFI-1, which will be 1 of 2 units returned on SpX-12.; the crew found corrosion on the fluid line connector. This activity has been paused until the ground teams can determine a forward plan of action. The MELFI is a cold storage unit that maintains experiment samples at ultra-cold temperatures until those samples can be returned to the ground for analysis.

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

ISS Daily Summary Report – 9/11/2017

Posted on September 11, 2017 at 4:00 pm by HQ.
 

Lung Tissue Operations and Removal:  On Saturday, the crew took samples and fixed media in the Tissue Bags, before inserting them in to a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  After completing the experiment, the crew disassembled the Lung Tissue hardware in the Microgravity Science Glovebox (MSG). The Lung Tissue investigation uses the microgravity environment of space to test strategies for growing new lung tissue. Using the latest bioengineering techniques, the Lung Tissue experiment cultures different types of lung cells in controlled conditions onboard the ISS. The cells are grown in a specialized framework that supplies them with critical growth factors so that scientists can observe how gravity affects growth and specialization as cells become new lung tissue.

Tropical Cyclone Irma: On Sunday, the crew configured the cameras in the Cupola and took a third set of pictures of Hurricane Irma. This is the first time the Tropical Cyclone investigation has captured three sets of pictures from the same storm.  Last week, Hurricane Irma peaked as a Category 5 for three days with maximum sustained wind at 185 miles per hour (mph). The Tropical Cyclone investigation is used to capture images of tropical cyclones and hurricanes that are rated at Category 3 or greater on the Saffir-Simpson scale. A pseudo-stereoscopic method is used to determine the altitudes of the cloud tops near the center (eye) of a cyclone by precisely tracking the apparent positions of cloud features with respect to the Earth and how those positions change over time as an observer (the ISS in this case) passes over the storm. The photographic images will be used to demonstrate that pseudo-spectroscopy can be used to measure the cloud altitudes to sufficient precision so that, when combined with other remote-sensing data, an accurate determination of the intensity of hurricane or cyclone can be made.

Lighting Effects: Over the weekend and this morning, the crew provided sleep log entries for the Lighting Effects investigation. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. Fluorescent bulbs are being replaced with solid-state light-emitting diodes (LEDs) that have adjustable intensity and color. Investigators will determine if the new lights improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have implications for people on Earth who use electric lights.

Multi-Omics-Mouse:  Today the crew transferred the Mouse Cage Units with the mice from the Cell Biology Experiment Facility (CBEF) to the Glove Box and performed routine maintenance operations by exchanging the waste collecting equipment, odor filters, and food cartridges.  Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function.  After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis.

Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Control Box Replacement: Earlier today, the crew began the 2nd of 6 suites of LMM enhancements to support upcoming ACE-T6 operations. While conducting the FIR LMM Control Box replacement, the crew could not reconnect the power and data cables to complete installation of the new control box. The clocking of the connectors on the new Control Box appeared to be different than those of the Control Box that was removed, which caused the two cables to interfere with one another to the point of precluding connection of either cable. The FIR rack was closed in a safe configuration and the cables remain disconnected. A forward plan is being worked to address the clocking issue. The other enhancements in the suite can be performed independent of this anomaly. The next activity (part 3) is scheduled for Thursday. 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).

MELFI (Minus Eighty Degree Laboratory Freezer for ISS) Electronic Unit Removal: Last week, the crew was scheduled to remove the failed Electronic Unit (EU) from MELFI-1, to return that EU and another previously failed EU on SpX-12.  A spare EU was scheduled to be installed in MELFI-1, bringing that facility back to an operational state. However, during the removal, fluid buildup was found on one of the connectors and the activity was suspended pending development of a cleanup procedure. Today the crew collected samples of the buildup before cleaning, removing, and packing the EU for return.  The MELFI is a cold storage unit that maintains experiment samples at ultra-cold temperatures until those samples can be returned to the ground for analysis.

ISS Daily Summary Report – 9/13/2017

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

52 Soyuz (52S) Dock: 52S launched from the Baikonur Cosmodrome this evening, and docked to the ISS bringing Misurkin, Acaba, and Vande Hei to the ISS. Docking to the Mini Research Module-2 (MRM-2) module was completed at 09:55 PM CDT with hatch opening at 12:08 AM CDT. The arrival of 52S increased the ISS crew complement from 3 to 6 crewmembers.

Fine Motor Skills (FMS): The crew performed a FMS session this morning. The FMS experiment is executed on a touchscreen tablet, where the crew 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 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.

Multi-Omics Mouse:  Today the crew collected samples for later analysis in support of the Multi-Omics Mouse investigation.  Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function.  After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis.

NanoRacks Module 9: The crew conducted the fourth operations session of NanoRacks Module 9 by activating mixture tubes in support of the NanoRacks-National Center for Earth and Space Science-Casper (NanoRacks-NCESSE-Casper) investigation.  NCESSE supports various schools and student-designed experiments that address challenges of living and working in space. The program is also a key initiative for U.S. science, technology, engineering and math (STEM), which strives to educate and inspire the next generation of scientists and engineers to work on the space program. 

Rodent Research 9 (RR-9):  The crew configured single stowage lockers to accommodate rodent habitats returning on SpX-12. The RR-9 experiment studies how microgravity affects the immune systems, muscles and bones of rodents during extended stays aboard the ISS.  After approximately 30 days aboard the ISS, the mice will be returned to Earth where scientists on the ground will study how their time in space has affected various tissues, including brain, muscle, heart, joint, the eyes and the immune system.

Space Station Remote Manipulator System (SSRMS) Latching End Effector A (LEE A) Survey: Today, the Robotics Ground Controllers powered up the Mobile Servicing System (MSS) and maneuvered the SSRMS to perform a survey of the LEE A latches using the P1 Lower Outboard (LOOB) External High Definition Camera (EHDC). No signs of damage was seen during the survey. The Robotics Ground Controllers also performed checkouts of LEE A in preparation for re-grappling SpaceX Dragon 12 on GMT Day 257 and of the Mobile Base System (MBS) Payload/Orbit Replaceable Unit (ORU) Accommodation (POA) in preparation for the LEE-A/POA swap during the Extra Vehicular Activity (EVA) on GMT 278.  Both the LEE A and the POA checkouts were nominal.  MSS performance today was also nominal.

ISS Daily Summary Report – 9/14/2017

Posted on September 14, 2017 at 4:00 pm by HQ.
 

iPad Operating System (iOS) Upgrade:  Today the crew connected the iPad Air 2 to an Space Station Computer (SSC), allowing ground controllers to update the operating system.

Dragon Departure Preparations:  Today the crew completed a computer based training session to review the Dragon departure documentation and a Robotic Onboard Trainer (ROBoT) session which included two simulated Dragon release runs. 

Commercial Orbital Transport Services (COTS) UHF Communication Unit (CUCU) Checkout:  In preparation for the upcoming SpaceX-12 unberth and release, the crew coordinated with ground teams to activate the CUCU System and perform a Crew Command Panel (CCP) checkout. The backup CCP unit was installed and checked out successfully, so the activity to change back to the prime CCP was aborted.  CCP and CUCU provides a command and telemetry communications link between ISS and Dragon during free flight operations in the vicinity of ISS.

Lighting Effects: Upon wakeup, the 51S subject provided a sleep log entry, and conducted a series of 3 Cognition tests throughout the day. The subject also completed 3 of 4 urine collections, which are divided within a 24-hour period. The fourth sample will be collected tomorrow morning.  Each sample is stowed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for freezing until their return and analysis. The Lighting Effects experiment hopes to better quantify and qualify how lighting can effect habitability of spacecraft. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. 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.

Gould Tribute Video: Today, a crewmember recorded a self-shooting video to pay tribute to Canadian pianist Glenn Gould. This video message will be part of a tribute concert by the Toronto Symphony Orchestra on September 22, in honor of Canadian pianist Glenn Gould, who would have turned 85 on September 25. Gould represented Canada on the “Golden Record” on board both Voyager 1 and 2. The video will also be promoted on social media.

Spaceborne Computer Installation and Checkout: The crew installed the Spaceborne Computer hardware into side-by-side EXPRESS Rack locker locations, configured the power, data, and thermal connections to the rack, before photographing the configuration and transferring the photos for downlink. Spaceborne Computer intends to run a year-long experiment of high performance commercial off-the-shelf (COTS) computer system on the International Space Station (ISS). During high radiation events, verify if the systems can still operate correctly by lowering their power, and therefore, speed. This research helps scientists identify ways of using software to protect ISS computers without expensive, time-consuming or bulky protective shielding.

Advanced Research Thermal Passive Exchange (ARTE) Thermal Exchange Setup and Hardware Stow: The crew completed the 2nd experiment run of the ARTE Thermal Exchange investigation. The Thermal Exchange hardware was installed in the MSG work volume, and the data was transferred from the SD card to the SSC for downlink. The hardware was then removed and stowed from the MSG. The ARTE Thermal Exchange investigation is sponsored by the Italian Space Agency (ASI); and studies the performance of a new type of heat pipe, which is a passive, low-weight device used to increase a material’s heat transfer capability. The investigation researches a new technology, called Axially Grooved Heat Pipes, which could be integrated into existing spacecraft, as well as used for future missions.

MagVector: The crew completed closeout and clean-up activities for the 13th experiment run of the MagVector investigation that began last week. The European Space Agency (ESA) MagVector investigation studies how Earth’s magnetic field interacts with an electrical conductor. Using extremely sensitive magnetic sensors placed around and above a conductor, researchers can gain insight into ways that the magnetic field influences how conductors work. This research not only helps improve future International Space Station experiments and electrical experiments, but it could offer insights into how magnetic fields influence electrical conductors in general, the backbone of our technology.

NanoRack Platforms-1 Module Removal: The crew removed NanoRacks Modules 67 and 72 from NanoRacks Platform-1 for return on SpaceX-12.
•NanoRack Module 67: NanoRacks-NDC-Ames for Space-Bacteria Testing determines whether bacteria mutate at a different rate in the microgravity environment of space. The experiments extend previous work on virulence in space by exposing different batches of bacteria to toxins known to cause mutations. Automated equipment tests and photographs batches of bacteria contained within different concentrations of toxins so that the observed mutation rates can be compared with those observed from control groups on Earth.
•NanoRack Module 72: NanoRacks-CUBERIDER-1 (NanoRacks-CR-1) is an educational module that runs on computer code written by 9th and 10th graders. Students program sensors on NanoRacks-CR-1 to record data on the microgravity environment and conduct tests aboard the station and then send results back to Earth. Through this investigation, students devise their own experiments and experience space science firsthand.

The NanoRack Platform is a multipurpose research facility that supports NanoRacks Modules by providing power and data transfer capabilities to operate investigations in microgravity.

Rodent Research 9 (RR-9):  To prepare for RR-9 Live Animal Return (LAR) activities, the crew will participated in a crew conference they setup and powered on the LAR transporters returning on SpX-12. The RR-9 experiment studies how microgravity affects the immune systems, muscles and bones of rodents during extended stays aboard the ISS.  After approximately 30 days aboard the ISS, the mice will be returned to Earth where scientists on the ground will study how their time in space has affected various tissues, including brain, muscle, heart, joint, the eyes and the immune system.

Tangolab-1 Card Cube Removal:  The crew removed two cards from the TangoLab-1 facility and inserted them into the Space Automated Bio-product Lab (SABL). The cards contain one experiment to study genetic mutations in fruit flies and one to study Carbon Dioxide scrubbing in cactus. TangoLab-1 is a reconfigurable general research facility designed for microgravity research and development and pilot manufacturing aboard the International Space Station (ISS).

Polar Sample Transfer from MELFI: The crew transferred samples from MELFI-1 and MELFI-2 to the four returning Polars using -32°C Ice Bricks and a Double Coldbag in preparation for SpaceX-12 descent.

ISS Daily Summary Report – 9/15/2017

Posted on September 15, 2017 at 4:00 pm by HQ.
 

Node 1 Communication:  Ground teams utilized the video conferencing system to patch Space to Ground channel 2 (S/G2) to an SSC in Node 1, and asked the crew to confirm that S/G2 voice was audible in Node 1.  Two separate configurations were tested, and both were confirmed to be audible.  Neither video nor return (ISS calling the ground) audio was enabled.  The ability to hear S/G2 calls in Node 1 has been a highly desired function.

Lighting Effects: Upon wakeup, the 51S subject provided a sleep log entry, and conducted the last of four urine collections, that were divided within a 24-hour period.  The sample was stowed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) for freezing until their return and analysis. The Lighting Effects experiment hopes to better quantify and qualify how lighting can effect habitability of spacecraft. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. 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.

Space Headaches: The crew completed questionnaires 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.

Sarcolab-3:  Today the crew set up and configured the Muscle Atrophy Research & Exercise System (MARES) facility in the Columbus module for Sarcolab-3 operations next week.  They installed the Ankle configuration and Electromyograph and Percutaneous Electrical Stimulation (PEMS) devices on MARES.  The data collected for Sarcolab-3 will be compared to pre and post-flight measurements to assess the impact of hypothesized microgravity induced muscle loss.  Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus, or calf muscle, where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

NanoRacks Module 9: The crew activated mixture tubes for the fifth NanoRacks Module 9 operations session in support of the NanoRacks-National Center for Earth and Space Science-Casper (NanoRacks-NCESSE-Casper) investigation.  NCESSE supports various schools and student-designed experiments that address challenges of living and working in space. The program is also a key initiative for U.S. science, technology, engineering and math (STEM), hat strives to educate and inspire the next generation of scientists and engineers to work on the space program.

ADvanced Space Experiment Processor (ADSEP):  The crew removed a Tissue cassette and two Cell Culturing (CellCult) cassettes from ADSEP. The Tissue cassette will be inserted in the Space Automated Bio-product Lab (SABL) and the CellCult cassettes will be inserted into a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  ADSEP is a thermally controlled facility that accommodates up to three cassette-based experiments that can be independently operated.  A collection of experiment cassettes is used to accommodate experiments in cell technology, multiphase fluids, solution chemistry, separation science, microencapsulation, and crystal growth.  For CellCult investigations, each cassette contains a rotating filtered bioreactor, a reservoir for fresh media, two peristaltic pumps, a waste reservoir, and up to 6 sample-collection or reagent containers connected by a manifold to the reactor. Cultures can be operated in continuous perfusion, batch fed, static, or sampling modes.  The removal of samples and the addition of additives to the reactor volume can be programmed or tele-operated.

Rodent Research 9 (RR-9):  The crew completed the RR-9 Live Animal Return (LAR) activities, by activating the lixits, installing food bars, and transferring the animals into the LAR transporters returning on SpX-12. The animals are safely stowed on SpX-12 and are ready for their return to Earth.  The RR-9 experiment studies how microgravity affects the immune systems, muscles and bones of rodents during extended stays aboard the ISS.  After approximately 30 days aboard the ISS, the mice will be returned to Earth where scientists on the ground will study how their time in space has affected various tissues, including brain, muscle, heart, joint, the eyes and the immune system.

CASIS Protein Crystal Growth PCG-6: The crew deactivated and inserted three PCG samples into the Minus Eight-degree Freezer for ISS (MELFI-2). Neutron Crystallographic Studies of Human Acetylcholinesterase for the Design of Accelerated Reactivators (CASIS PCG 6) produces crystals of acetylcholinesterase, a medically important neurotransmitter enzyme. Crystals grown in microgravity are larger and higher-quality and can be used for the technique called macromolecular neutron crystallography (MNC) to locate hydrogen atoms in the crystal structure. These hydrogen atoms play critical roles in the enzyme function and knowing their location clarifies that function. This advances development of better antidotes to fatal Organophosphate nerve agents, which act by inhibiting acetylcholinesterase in the nervous system.

CASIS Protein Crystal Growth (PCG-7): The crew inserted 10 PCG samples into to the Minus Eight-degree Freezer for ISS (MELFI-2). Crystallization of LRRK2 Under Microgravity Conditions (CASIS PCG 7) uses the microgravity environment aboard the ISS to grow larger versions of an important protein, LRRK2, implicated in Parkinson’s disease. Defining the exact shape and morphology of LRRK2 would help scientists better understand the pathology of Parkinson’s and aid in the development of therapies against this target, but gravity keeps Earth-grown versions of this protein too small and too compact to study. CASIS PCG 7 uses automated biotechnology devices to grow larger versions of this protein in space, which are then returned to Earth for detailed laboratory analysis.

Dragon Packing:  Today the crew packed and loaded items into the SpaceX-12 Dragon capsule for return to Earth.

Dragon Grapple:  Overnight, the Station Space Station Remote Manipulator System (SSRMS) was maneuvered from the post-Latching End Effector (LEE) A survey park position to the SpX-12 Dragon capture position. SSRMS then grappled Dragon nominally. The SSRMS was powered down to Dual String Keep Alive (DSKA). Dragon release is scheduled for this Sunday.

ISS Daily Summary Report – 9/18/2017

Posted on September 18, 2017 at 4:00 pm by HQ.
 

Dragon SpaceX (SpX)-12 Unberth:  Over the weekend, the crew packed critical items and egressed the vehicle in preparation for Dragon departure.  Dragon was unberthed from the ISS via ground commanding on Saturday at approximately 5:06 PM CDT.  Ground teams then maneuvered the Dragon to an overnight park position.  Early Sunday morning at 03:41 AM CDT, Dragon was released, with splashdown occurring roughly five and a half hours later.

Multi-Omics-Mouse:  On Saturday, the crew transferred the Mouse Habitat Cage Units from the Cell Biology Experiment Facility (CBEF), to the Transportation Cage Units for return on SpaceX-12. Several studies have reported space flight effects on the human immune system, but the relationship between microbiota and immune dysfunction during flight remains unclear. In the Multi-Omics-Mouse investigation, food with and without fructooligosaccharides (FOS) will be used as prebiotics, to determine if they improve the gut environment and immune function.  After the flight, researchers will analyze the gut environment (microbiota and metabolites) and immune system of the mice by multi-omics analysis.

ADvanced Space Experiment Processor (ADSEP):  On Saturday, the Tissue cassette that was inserted into the Space Automated Bio-product Lab (SABL) on Friday, was removed and returned on SpX-12. ADSEP is a thermally controlled facility that accommodates up to three cassette-based experiments that can be independently operated.  A collection of experiment cassettes is used to accommodate experiments in cell technology, multiphase fluids, solution chemistry, separation science, microencapsulation, and crystal growth.  For CellCult investigations, each cassette contains a rotating filtered bioreactor, a reservoir for fresh media, two peristaltic pumps, a waste reservoir, and up to 6 sample-collection or reagent containers connected by a manifold to the reactor. Cultures can be operated in continuous perfusion, batch fed, static, or sampling modes.  The removal of samples and the addition of additives to the reactor volume can be programmed or tele-operated.

Lighting Effects: Over the weekend, a 51S crewmember provided sleep log entries for the Lighting Effects investigation. The light bulbs on the ISS are being replaced with a new system designed for improved crew health and wellness. Fluorescent bulbs are being replaced with solid-state light-emitting diodes (LEDs) that have adjustable intensity and color. Investigators will determine if the new lights improve crew circadian rhythms, sleep, and cognitive performance. Results from this investigation also have implications for people on Earth who use electric lights.

Space Headaches: Over the weekend and today, a 52S crewmember completed daily questionnaires 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.

Marrow:  With operator assistance, a 52S crewmember collected blood samples for the Marrow investigation. The breath and ambient air sample collection was aborted due to an issue with the collection hardware. After resolving the hardware issue, the breath and ambient collection operations was rescheduled for tomorrow. The blood samples were processed in the centrifuge and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).  The Marrow investigation 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.

Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 51S crewmember  performed a series of urine collections in support of the Biochemical Profile and Repository experiments.  The urine samples were collected and placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The blood samples will be collected tomorrow.
•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.

Sarcolab-3:  Prior to conducting the operations segment of the Sarcolab-3 investigation, the crew completed setup activities for Ultrasound 2. Then, with assistance from a Russian operator, a USOS crewmember ingressed the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module and adjusted pads and constraints for the Sarcolab-3 ankle protocol which is ongoing.  The operator then collected ultrasound images of the subject’s leg. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss.  Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

Zero Boil-OFF Tank (ZBOT) Hardware Setup: Today the crew configured the majority of the ZBOT hardware in the Microgravity Science Glovebox (MSG) Work Volume and will complete the remaining setup activities tomorrow. The final configuration will be photographed for historical documentation. Rocket fuel, spacecraft heating and cooling systems, and sensitive scientific instruments rely on very cold cryogenic fluids. Heat from the environment around cryogenic tanks can cause their pressures to rise, which requires dumping or “boiling off” fluid to release the excess pressure, or actively cooling the tanks in some way. ZBOT uses an experimental fluid to test active heat removal and forced jet mixing as alternative means for controlling tank pressure for volatile fluids.

ISS Daily Summary Report – 9/19/2017

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

Space Headaches: The daily questionnaire for the ESA Space Headaches investigation was completed by a 52S crewmember.  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.

Marrow:  Today the crew successfully collected the breath and ambient air samples that were not able to be completed yesterday due to an issue with the collection hardware.  The Marrow investigation 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.

Human Research Program (HRP) Collections (Biochemical Profile, Repository): Today a 51S crewmember completed the urine sample collections that began yesterday in support of the Biochemical Profile and Repository experiments. With operator assistance, the subject also conducted blood sample collections and the samples were processed for double spin operations using the Refrigerated Centrifuge prior to being 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.

Zero Boil-OFF Tank (ZBOT) Hardware Setup: The crew completed the ZBOT hardware configuration in the Microgravity Science Glovebox (MSG) Work Volume that began yesterday. Rocket fuel, spacecraft heating and cooling systems, and sensitive scientific instruments rely on very cold cryogenic fluids. Heat from the environment around cryogenic tanks can cause their pressures to rise, which requires dumping or “boiling off” fluid to release the excess pressure, or actively cooling the tanks in some way. ZBOT uses an experimental fluid to test active heat removal and forced jet mixing as alternative means for controlling tank pressure for volatile fluids.

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. 

Space Test Program – H5 Innovative Coatings Experiment (STP-H5 ICE): The crew photographed four ICE material strips on STP-H5. The harsh radiation and extreme temperatures of space can corrode the paint and coatings that protect spacecraft exteriors, potentially damaging a spacecraft’s hull. Optical coatings are also important for robotic and human navigators, who would rely on specialized markings to capture or repair spacecraft. The STP-H5 ICE investigation studies new coatings for use on spacecraft in low-Earth orbit, determining their stability after 2 years in space.

Combustion Integrated Rack (CIR) Configuration for Advanced Combustion via Microgravity Experiments (ACME): The crew began configuration activities for the CIR optics bench which supports the ACME investigation. Due to the amount of hardware requiring installation, configuration activities will be conducted over the next two days. 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.

Fast Neutron Spectrometer: The crew completed the installation of the Fast Neutron Spectrometer in Node 1. Neutron spectrometers are used to make a wide range of measurements, including studies of a planetary body’s composition and measuring the flux of high-energy neutrons that could be harmful to humans. The Fast Neutron Spectrometer (FNS) investigation studies a new neutron measurement technique that is better suited for the mixed radiation fields found in deep space. Future manned and exploration missions benefit from clearer, more error-free measurement of the neutron flux present in an environment with multiple types of radiation.

Sarcolab-3:  With USOS operator assistance, a Russian subject ingressed the Muscle Atrophy Research & Exercise System (MARES) chair in the Columbus module and adjusted pads and constraints for the Sarcolab-3 ankle protocol.  The operator then collected ultrasound images of the subject’s leg. The subject is continuing the Sarcolab protocol.  The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss.  Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

EVA Mobility Unit (EMU) Resize:  Today the crew will continue activities to prepare for the upcoming EVAs.  They will resize EMUS to fit the specific crewmembers that will go outside during those upcoming EVAs.  The goals of the EVAs include performing an R&R on the SSRMS Latching End Effector (LEE) A, lubrication of the LEEs, and external camera replacement.

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.

Combustion Integrated Rack (CIR) Configuration for Advanced Combustion via Microgravity Experiments (ACME): The crew configured the CIR optics bench that will be used to support the ACME investigation. Due to the amount of hardware requiring installation, configuration activities took a couple of days this week to complete. 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.

Sarcolab-3: Today a USOS subject ingressed the Muscle Atrophy Research & Exercise System (MARES) chair, located in the Columbus module, while a Russian operator collected ultrasound images of the subject’s right leg during exercise activities. This completed the third and final day of the ankle configuration exercises, which were performed by three different USOS and Russian crewmembers. Later today, the MARES hardware was re-configured to support tomorrow’s knee configuration exercises. The data collected for Sarcolab-3 will be compared to pre and post-flight measurements to assess the impact of hypothesized microgravity induced muscle loss. Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crew members before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

Multi-Omics-Mouse Consolidation:  Following the successful completion and return of the Multi-Omics investigation last week, the crew completed item consolidation tasks and returned the Cell Biology Experiment Facility (CBEF) back to its nominal configuration.

EVA Preparation:  In preparation for the upcoming EVAs, the crew completed Enhanced Caution and Warning System (EWCS) training and EMU battery charging.

S-Band String 2 Troubleshooting: Yesterday, the ground team swapped S-Band string 1 to string 2 to gain confidence in its performance. On August 6, 2017, String 2 S-Band/UHF Audio Interface (AUAI)-1P showed intermittent functionality after an AUAI Passive Built-In Test (PBIT) fault indication. Space to Ground (S/G) audio on channels 1 and 2 became unusable. Functionality was recovered by switching to S-band string 1. Since the event, multiple attempts to duplicate the signature have been unsuccessful. The plan is to remain on string 2 until the schedule USOS EVAs in early October.
