ISS Daily Summary Report – 10/09/2018
 


Lighting Effects: A Crewmember provided a sleep log entry upon waking. 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.

JAXA Low Temperature Protein Crystal Growth (LT PCG): Low Temp Protein Crystal Growth samples were prepared and inserted into the Glacier facility. The goal of the JAXA LT PCG experiment is to produce high quality protein crystals in a microgravity environment at a low temperature.

JEM Small Satellite Orbital Deployer (J-SSOD): The J-SSOD #10 launch hardware was removed from the Multi-Purpose Experiment Platform in preparation of the Loop Heat Pipe Radiator installation. J-SSOD provides a novel and safe small satellite launching capability from the ISS.

Demonstration of Loop Heat Pipe Radiator (LHPR) System: The Crew installed the LHPR System and the External Ethernet Extender onto the Multi-Purpose Experiment Platform inside the JEM Airlock for future deployment. LHPR is an advanced two-phase heat transfer device that utilizes the evaporation and condensation of a working fluid to transfer heat, and the capillary force to circulate the fluid. This investigation demonstrates the heat transfer performance/functions under microgravity conditions using the LHPR experimental apparatus, which is grappled by the JEM Remote Manipulator System (JEMRMS). This technology can be applied in the thermal control system of future satellites that generate large amounts of heat that could negatively affect satellite operations.

Binary Colloidal Alloy Test – Cohesive Sediment (BCAT-CS): The Crew checked the camera alignment and focus by viewing the latest BCAT images on a laptop. BCAT-CS focuses on the study of forces between particles that cluster together by using sediments of quartz and clay particles. Conducting the research in the microgravity environment of the ISS makes it possible to separate the forces acting on the particles over a short range (adhesive forces) versus those acting over a long range (cohesive forces). The quartz/clay system is commonly found in a wide variety of environmental settings (such as rivers, lakes, and oceans) and plays an important role in technological efforts related to deep-sea hydrocarbon drilling and carbon dioxide sequestration.

Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Biophysics: Crew reconfigured the FIR LMM Biophysics facility and installed the Biophysics Plate 2 into the LMM Petri Base Auxiliary Fluids Container. Proteins are important biological molecules that can be crystallized to provide better views of their structure, which helps scientists understand how they work. Proteins crystallized in microgravity are often higher in quality than those grown on Earth. The Effect of Macromolecular Transport on Microgravity Protein Crystallization (LMM Biophysics 4) studies why this is the case, examining the movement of single protein molecules in microgravity.

Human Resources Facility (HRF) 1: Crew unstowed a Z-Book to be used as HRF Portable Computer 1 and connected it Express Rack 3. The new Z-book laptops will be used for upcoming NeuroMapping sessions. HRF-1 provides an on-orbit laboratory that enables scientists conducting human life science research to evaluate the physiological, behavioral, and chemical changes induced by space flight. Research performed using HRF-1 provides data to help scientists understand how the human body adapts to long-duration spaceflight.

Basic Express Rack 10 (ER-10B): Express Rack 10B was activated by the ISS Crew for the first time today. The new rack arrived on HTV-7 and was previously installed by the Crew. Today’s activities included initiating the Manual Flow Control Valve that will affect the Moderate Temperature Loop (MTL)flow into the Rack. In addition, they worked with the ground teams and successfully performed the initial activation and checkout of the rack. EXpedite the PRocessing of Experiments for Space Station (EXPRESS) Racks are multipurpose payload rack systems that store and support research aboard the ISS. The EXPRESS Racks support science experiments in any discipline by providing structural interfaces, power, data, cooling, water, and other items needed to operate science experiments in space.

VHF-1 Emergency Comm Checks: The Crew configured USOS and ROS Audio Subsystems to support successful VHF-1 comm checks with Houston, Huntsville, Tsukuba, and Moscow via the Wallops Flight Facility. VHF-1 provides an emergency back up for ISS to ground communications and is verified using each of the three U.S. ground sites at least once per year.

ISS Daily Summary Report – 10/10/2018
 


Waste and Hygiene Compartment (WHC) Anomaly: Shortly after Crew wake, the Crew reported all lights were off on the WHC Control Panel and the associated power switch was in the off/tripped position. Attempts to reactivate WHC were not successful. The crew then performed troubleshooting steps in order to isolate the problem to the WHC Pump Separator. The Pump Separator was successfully replaced with an onboard spare. WHC is now operating nominally.

Lighting Effects: A crewmember recorded Light Meter readings for an empty crew quarter compartment. 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.

Electro-static Levitation Furnace (ELF): Crew replaced the Gas Bottle for ELF as ground teams discovered that the previous bottle is currently depleted. ELF is an experimental facility designed to levitate, melt and solidify materials by containerless processing techniques using the electrostatic levitation method.  With this facility thermophysical properties of high temperature melts can be measured and solidification from deeply undercooled melts can be achieved.

Actiwatch Spectrum: The Actiwatch Spectrum hardware was setup for checkout and then stowed by the ISS crew. The Actiwatch Spectrum is a waterproof, nonintrusive, sleep-wake monitor worn on the wrist of a crewmember. The device contains an accelerometer for measuring motion and color sensitive photodiodes (a photodetector capable of converting light into voltage) for monitoring ambient lighting. Together, these capabilities enable the Actiwatch Spectrum to be used to analyze circadian rhythms, sleep-wake patterns, and activity.

Advanced Combustion via Microgravity Experiments (ACME) / Electric-Field Effects on Laminar Diffusion (E-FIELD) Flames: The crew replaced the Manifold 4 bottle and the ground will be downlinking files from ACME test points and monitoring the bottle pressure. For E-Field Flames an electric field with voltages as high as 10,000 volts is established between the burner and a mesh electrode. The motion of the charged ions, which are naturally produced within the flame, are strongly affected by a high-voltage electric field. The resulting ion-driven wind can dramatically influence the stability and sooting behavior of the flame. Conducting the tests in microgravity allows for great simplifications in the analysis, enabling new understanding and the development of less polluting and more efficient combustion technology for use on Earth.

Life Support Rack (LSR): The crew prepared the O2 generator, performed the Red Helium Camera setup, and performed a meter reading. LSR is a Technology Demonstrator for Closed Loop Air Revitalization. LSR captures carbon dioxide from cabin air and recovers 50% of its oxygen for use by the astronauts. LSR operates for a minimum of one year on the International Space Station to demonstrate the robustness of the technology for future Exploration Missions.

Aerosol Samplers: All Sampler drawers were closed and stowed. The Samplers have individual drawer-like surfaces covered with sticky carbon tape that will capture aerosols in the ISS air. Aerosols are small particles suspended in the air. In the Earth’s atmosphere they include soot, dust, pollen and a wide range of other natural and human-made materials. Because smoke and dust do not move in microgravity the way they do on Earth, aerosols in the ISS air pose hazards for crewmembers. The Aerosol Samplers investigation collects airborne particles in the ISS cabin air and returns them to Earth so scientists can study the particles with powerful microscopes.

Spacewalk to inspect hole in Soyuz spacecraft’s hull cancelled over aborted rocket launch
Quote
A spacewalk to inspect a hole in the manned Soyuz MS-09 spacecraft’s hull scheduled for mid-November has been cancelled due to the abortive launch of the Soyuz-FG carrier rocket, Roscosmos Executive Director for Manned Programs Sergei Krikalyov said on Friday.
"The spacewalk was planned for mid-November. Alexei Ovchinin and Sergei Prokopyev were expected to make the spacewalk together. There will be no spacewalk on November 15. We will see, if we manage to make the shift intervals long enough, we will try to make this spacewalk with one of the next crews. The flight program will now be on hold and revised," Krikalyov said.

MEDIA ADVISORY M18-150

Missouri, Colorado Students to Speak with Astronaut on Space Station

Elementary school students from Missouri and Colorado will talk live with an astronaut on the International Space Station next week. Both Earth-to-space calls will air live on NASA television and the agency’s website.

NASA astronaut Serena Auñón-Chancellor will answer questions posed by 4th grade students from Katie Harper Wright Elementary School in St. Louis at 1:15 p.m. EDT on Monday, Oct. 15. The downlink is in association with the National Park Service’s recognition of both the 50th anniversary of the National Trails System and NASA’s 60th anniversary.

A National Park Service mascot, Seaman Jr., a plush toy replica of the original Newfoundland dog, Seaman made its way to the International Space Station. Seaman explored the trail with his owner, Capt. Meriwether Lewis and colleague 2nd Lt. William Clarkon their Corps of Discovery Expedition across the Louisiana Purchase from 1804 to 1806. From the space station’s unparalleled perspective of Earth, Seaman Jr. tracked the 3,700 mile Lewis and Clark National Historic Trail. Seaman Jr.’s travels abroad the station will debut during the downlink.

The event will be held the Gateway Arch National Park at 11 North 4th St, St. Louis. Media interested in covering should contact Erin Hilligoss-Volkmann at [email protected] 314-655-1615.

Auñón-Chancellor also will answer questions from Frontier Academy and Dos Rios Elementary School students at noon on Thursday, Oct. 18 in Evans, Colorado. The downlink will be hosted by High Plains Library District based in Greeley, Colorado, in collaboration with the Space Science Institute and its National Center for Interactive Learning. Students will participate in hands-on science and engineering activities surrounding the downlink, and the event will be streamed live to other public libraries and schools across the country.

The event will be held at Riverside Library and Cultural Center at 3700 Golden St, Evans. Media interested in covering should contact Kelli Johnson at [email protected] 970-506-8560.

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 mathematics (STEM). Astronauts living in space on the orbiting laboratory communicate with NASA’s Mission Control Center in Houston 24 hours a day through the Space Network’s Tracking and Data Relay Satellites (TDRS).

ISS Daily Summary Report – 10/11/2018
 


56 Soyuz (56S) Anomaly: 56S launched today at 3:40 AM CDT.  At 3:42 AM CDT the Soyuz crew reported that a booster failure had occurred.  Per standard response to a booster abort in this timeframe, the descent module separated and performed a ballistic descent and landing near Dzhezkazgan, Kazakhstan.  At 4:20 AM CDT, Russian Search and Rescue forces arrived at the landing location after which the crew was safely extracted and transported to Dzhezkazgan via helicopter. They were subsequently transported via fixed wing aircraft to Baikonur, Kazakhstan.

Team Task Switching (TTS): The crew completed a TTS survey today. When crewmembers are required to switch their attention between tasks frequently, performance on each of the tasks can be negatively affected.  The objective of the TTS investigation is to gain knowledge about whether or not crewmembers have difficulty in switching tasks and determine the impacts of these switches to both reduce any negative consequences and improve individual and team motivation and effectiveness.

Food Acceptability: The crew completed the Food Acceptability questionnaires today. This investigation seeks to determine the impact of repetitive consumption of food currently available from the spaceflight food system.  Results will be used in developing strategies to improve food system composition to support crew health and performance on long duration missions.

Myotones: The crew gathered Myotones Hardware in preparation of upcoming operations. The investigation observes the biochemical properties of muscles during long-term exposure to the spaceflight environment. Results from this investigation are expected to provide insight into principles of human resting muscle tone which could lead to the development of new strategies for alternative treatments for rehabilitation both on Earth and for future space missions.

Basic Express Rack #10B Locker remove: Lockers were removed from the newly installed Basic Express Rack (BER) #10B and stowed in new locations. EXpedite the PRocessing of Experiments for Space Station (EXPRESS) Racks are multipurpose payload rack systems that store and support research aboard the ISS. The EXPRESS Racks support science experiments in any discipline by providing structural interfaces, power, data, cooling, water, and other items needed to operate science experiments in space.

HII Transfer Vehicle (HTV)-7 Cargo Transfer: The crew continued HTV-7 cargo transfer operations today. Ground specialists estimate approximately 15 hours remain to complete transfer.

ISS Daily Summary Report – 10/12/2018
 


56 Soyuz (56S) Anomaly Follow Up:   Following yesterday’s launch anomaly, the 56S crew returned to Moscow after medical evaluations in Baikonur, Kazakhstan.  Roscosmos has created an investigative commission to look into the booster anomaly. In addition, Energia has formed a commission to find ways to improve performance and reliability of the Soyuz launch escape system.  ISS Increment Teams are actively replanning activities as a result of the launch anomaly.

HII Transfer Vehicle (HTV)-7 Cargo Transfer:  The crew continued HTV-7 cargo transfer operations today. Ground specialists estimate approximately 10 hours remain to complete transfer.

Myotones Measurements:  A crewmember performed skin marking and measurements with the Myotones Device. Data was then transferred to the laptop. Myotones investigation observes the biochemical properties of muscles during long-term exposure to the spaceflight environment. Results from this investigation are expected to provide insight into principles of human resting muscle tone, which could lead to the development of new strategies for alternative treatments for rehabilitation both on Earth and for future space missions.

Sextant Navigation:  The Crew performed the sixth Sextant Navigation session using the Star, planet and Moon Limb sighting. .  The primary science objective of sighting using the method of lunar distances was fully accomplished. This session also served to rehearse the technique that will be used for Orion lunar navigation. Astronauts onboard the ISS test a hand-held sextant that is intended for use on future Orion exploration missions. The results from this investigation can aid in the development of emergency navigation methods for future manned spacecraft. Historically, Gemini missions in 1965-66 were the first to exercise sextant sightings from a spacecraft. A sextant was built into Apollo vehicles as a navigation backup in case of lost communications.

Basic Express Rack #10B Locker remove:  Lockers were removed from the newly installed Basic Express Rack 10B and stowed in new locations. EXpedite the PRocessing of Experiments for Space Station (EXPRESS) Racks are multipurpose payload rack systems that store and support research aboard the ISS. The EXPRESS Racks support science experiments in any discipline by providing structural interfaces, power, data, cooling, water, and other items needed to operate science experiments in space.

Time Perception in Microgravity: Time Perception in Microgravity: The crew performed a Time perception session. The accurate perception of objects in the environment is a prerequisite for spatial orientation and reliable performance of motor tasks.  Time is fundamental to motion perception, sound localization, speech, and fine motor coordination.

NanoRacks Platform 3 Relocate: The NanoRacks Platform 3 was relocated from Express Rack 4 to Express Rack 10B. NanoRacks Platforms is a multipurpose research facility on board the ISS. NanoRacks Platforms supports NanoRacks Modules in the CubeSat form factor by providing power and data transfer capabilities to operate investigations in microgravity.

This technology can be applied in the thermal control system of future satellites that generate large amounts of heat that could negatively affect satellite operations.

Life Support Rack (LSR): ISS crew continued configuration for the Life Support rack by installing the CO2 absorbers and setup of the Air Water Management System. LSR is a European Space Agency technology demonstrator for closed loop air revitalization. It captures carbon dioxide from cabin air and recovers 50% of its oxygen for use by the astronauts. LSR operates for a minimum of one year on the ISS to demonstrate the robustness of the technology for future Exploration Missions

Zero-g Battery Testing: A crewmember completed testing of a sample alkaline batteries. All batteries passed and were restowed for return. Over many years, some crewmembers have reported that batteries on orbit do not last as long as they do on the ground. In the Zero-g Battery Testing experiment, an ISS crew member installs several sets of batteries into a standard camera flash, identifies batteries that fail to work, and returns them to the ground for analysis. If battery life is, in fact, shorter in space, this knowledge could lead to development of better batteries for use in space and on the ground.

HII Transfer Vehicle (HTV)-7 Cargo Transfer: The crew continued HTV-7 cargo transfer operations today. Ground specialists estimate approximately ~7 hours remain to complete transfer of identified items.

ISS Daily Summary Report – 10/16/2018
 
Cold Atom Lab (CAL):  A Crewmember attached the Helium monitor to the front of the CAL hardware to collect readings. The CAL produces clouds of atoms that are chilled to about one ten billionth of a degree above absolute zero — much colder than the average temperature of deep space. At these low temperatures, atoms have almost no motion, allowing scientists to study fundamental behaviors and quantum characteristics that are difficult or impossible to probe at higher temperatures. In microgravity, researchers may be able to achieve even colder temperatures than what is possible on the ground, and observe these cold atom clouds for longer periods of time.

Lighting Effects:  Crew performed a numerical and color discrimination visual test at a designated location. 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.

Radiation Dosimetry Inside ISS-Neutrons (RADI-N2): Today the eight detectors were retrieved from NOD3F3 rack front area location and handed back to the Russian crew for data extraction and download. This Canadian Space Agency investigation measures neutron radiation levels in the ISS.  These bubble detectors are designed to only detect neutrons and ignore all other radiation.

BioServe Protein Crystallography (BPC)-1: A crewmember used pipettes to mix varying viscosity solutions into the crystallization plates. BPC-1 seeks to demonstrate the feasibility of conducting protein crystal growth in real time onboard the ISS.  Crewmembers add solutions to the hardware, observe the crystals that form and adjust for follow-on experiments. This approach gives scientists the ability to optimize crystal growth in microgravity instead of waiting for samples to return and then launching them again.

HII Transfer Vehicle (HTV)7 Cargo Transfer:  The crew continued HTV7 cargo transfer operations today. Ground specialists estimate approximately ~4 hours remain to complete transfer of identified items.

Extravehicular Mobility Unit (EMU) Li-Ion Battery Data Logging:  Today the crew initiated a charging Auto cycle of two EMU Long Life Batteries (LLB) with data logging. Over the course of three days, the Auto cycle will capture battery health data and help ground experts understand the charge and discharge capacities of these new and improved LLBs. The data will also be used to compare charging system performance between the on-orbit and ground based systems.

BioServe Protein Crystallography (BPC)-1:  Crew performed viscosity solutions into Crystallization plates mixing. Plate samples were stowed in the SABL unit. BPC-1 seeks to demonstrate the feasibility of conducting protein crystal growth in real time onboard the ISS. Crewmembers add solutions to the hardware, observe the crystals that form and adjust for follow-on experiments. This approach gives scientists the ability to optimize crystal growth in microgravity instead of waiting for samples to return and then launching them again.

JAXA Low Temperature Protein Crystal Growth (LT PCG):  Ice packs were placed into the Freezer-Refrigerator Of STirling cycle (FROST)-2 unit in preparation for LT PCG4 samples that will eventually be transferred to the HTV Small Return Capsule (HSRC). The goal of the JAXA LT PCG experiment is to produce high quality protein crystals in a microgravity environment at a low temperature.

Waste and Hygiene Compartment (WHC) Pre-Treat Tank Remove and Replace (R&R):  Today the crew R&R’d the Pre-Treat Tank as part of nominal WHC preventative maintenance. During the activity, the crew discovered pretreat liquid that had leaked into the containment hose connected to the vent caps on the new tank. The leaking tank was bagged and stowed and an alternate tank was subsequently used to complete the R&R.  Each tank contains five liters of pre-treat solution, a mix of acid, chromium oxide, and water, used for toilet flushing and required for nominal WHC operation.

LAB 1 Port 1 (LAB1P1) Pivot Fitting Swap:  During installation of the Life Support Rack (LSR) on October 1, the Active Rack Isolation System (ARIS) pivot brackets were removed from LAB1P1 and replaced with Ishikawajima-Harima Heavy Industries [IHI] style pivot brackets. However, when the crew attempted to re-reinstall an area smoke detector, a 1 cm interference between the smoke detector mounting plate and the new IHI pivot bracket was reported. Today, the crew removed the IHI pivot bracket and replaced it with outside-style ARIS pivot fittings. This eliminated interference between the pivot fitting and the smoke detector bracket.

System Operations Data File (SODF) Warning Book Updates:  The crew printed and incorporated updates to Warning procedure books today. The changes are required in support of Life Support Rack activation, expected early November.

Advanced Resistive Exercise Device (ARED) Quarterly Maintenance:  The crew completed ARED quarterly maintenance, which includes steps to inspect the x-rotation dashpots, cycle the main arm through the full range of motion and grease ARED Vibration Isolation System (VIS) rails and rollers.
