ISS Daily Summary Report – 07/07/14

Posted on July 7, 2014 by HQ.
 

Radi-N2 Neutron Field Study (Radi-N2): Commander (CDR) Swanson deployed eight bubble detectors around the ISS for the Radi-N2 experiment. The objective of this investigation is to better characterize the ISS neutron environment and define the risk posed to the crewmembers’ health and provide the data necessary to develop advanced protective measures for future space flight.

Burning and Suppression of Solids (BASS)-II Operations: FE-5 Wiseman completed flame tests for the BASS-II investigation. Seven acrylic film samples were burned in air at various flow rates. Wiseman also burned a one-sided acrylic slab 4 mm thick. The BASS-II investigation examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The BASS-II experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

European Space Agency (ESA) Education Payloads Operations (EPO) Rosetta: FE-6 Gerst simulated the docking of the Rosetta mission scheduled to take place in November 2014. The mission consists of a lander called Philae docking to Comet 67P/Churyumov‐Gerasimenko. Philae will harpoon itself to the comet, take images, and retrieve samples for analysis. Gerst will demonstrate this mission on the ISS using a Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) satellite, a light object such as an earplug, and Velcro. This EPO will be recorded and downlinked for educational purposes.

Biochemical Profiles: FE-6 Gerst collected blood and urine for the Flight Day 30 Biochemical Profiles investigation. The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body.

On-board Training (OBT) Cygnus Robotics Onboard Trainer (ROBoT) Session 2: In preparation for next week’s planned Orb-2 arrival, Swanson, Gerst and Wiseman performed the 2nd session of this OBT. They practiced Cygnus approach from 30 meter hold through capture. The OBT also provides the chance to practice coordination among crew members.

Joint Station LAN (JSL) Japanese Experiment Module (JEM) Pressurized Module (JPM) 16-Port Ethernet Switch Install: Swanson installed a 16-Port Ethernet Switch in the JPM to expand support for ethernet devices such as the AVN443 High Definition (HD) encoder and XF305 camcorder hardware as well as additional SSC/CSL clients and payloads. Tomorrow he will deploy the HD Encoder and XF305 Camcorder in the JEM.

ISS Daily Summary Report – 07/08/14

Posted on July 8, 2014 by HQ.
 
Burning and Suppression of Solids (BASS)-II Operations: Flight Engineer (FE)-5 Wiseman conducted six flame tests for the BASS-II investigation. Clear and black rods were burned under the same conditions for comparison. The BASS-II investigation examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The BASS-II experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

Cell Biology Experiment Facility (CBEF) Maintenance: Commander (CDR) Swanson cleaned inside the CBEF micro-gravity and 1-gravity chambers. This is a periodic maintenance task for the CBEF.

Capillary Flow Experiment (CFE) Interior Corner Flow (ICF) Test: FE-6 Gerst set up hardware on the Maintenance Work Area (MWA) and then conducted ICF tests using the ICF8 hardware, which contains a segmented, 50 degree snow cone section. Gerst performed several drain tests with and without bubbles. CFE ICF studies capillary flow in interior corners of vessels with various geometries. Structured inside tanks providing interior corners are used in the design of fuel tanks to promote fuel flow to the outlet of the tank in the absence of gravity. Experimental results will provide the necessary boundary conditions as a function of container cross section and fill fraction. The benchmarked theory can be used to improve propellant management aboard spacecraft.

Binary Colloidal Alloy Test (BCAT)-Low Gravity Phase Kinetics Platform (KP) Sample Mixing: Wiseman mixed BCAT-KP samples 4 and 5 for a future BCAT-KP run in the Fluids Integrated Rack (FIR). Wiseman noted that sample 5 had approximately 12-15 bubbles. BCAT-KP provides a platform for material and industrial scientists to investigate colloid phase changes, providing results that may be used to develop new colloidal materials and formulations with unique properties. The results may support new applications, from new liquid crystals to consumer goods having longer shelf life and uses.

Joint Station LAN (JSL) Japanese Experiment Module (JEM) Pressurized Module (JPM) 16-Port Ethernet Switch Deploy: Yesterday Swanson installed a 16-Port Ethernet Switch in the JPM to expand support for ethernet devices such as the AVN443 High Definition (HD) encoder and XF305 camcorder hardware as well as additional Station Support Computer (SSC)/Crew Support Lan (CSL) clients and payloads. Today he deployed the HD Encoder and XF305 Camcorder in the JEM.   The voice and video checks with the ground will be performed tomorrow.

Node 2 (N2) Vestibule Fiber Optic Jumper Inspection: Swanson visually inspected jumper harnesses for damage and verified fiber optic jumper connectors are mated correctly in the N2 Starboard/Columbus Vestibule, N2 Port/JEM Pressurized Module (JPM) Vestibule and N2 Aft/LAB Vestibule.

ISS Daily Summary Report – 07/09/14

Posted on July 9, 2014 by HQ.
 

Burning and Suppression of Solids (BASS)-II Operations: FE-5 Wiseman conducted seven flame tests for the BASS-II investigation. Six of the samples were fabric and the seventh was an acrylic, spherical material. The BASS-II investigation examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The BASS-II experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

Sprint Operations: Commander (CDR) Swanson completed his Flight Day (FD) 105 Sprint Volume of Oxygen Utilized (VO2) protocol using the Blood Pressure (BP)/Electrocardiogram (ECG) hardware. Sprint evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in ISS crewmembers during long-duration missions.

European Space Agency (ESA) Education Payloads Operations (EPO): FE-6 Gerst completed a foaming water demonstration which was recorded and downlinked to the ground for education purposes.

Skin-B Sample Collection: Gerst conducted his third Skin-B data collection using the Tewameter probe to measure the skin barrier function; the Visioscan Camera to measure skin surface topography; and the Corneometer probe to measure skin hydration. The Skin-B experiment will improve understanding of skin aging which is slow on Earth but very much accelerated in space. This will also provide insights into the aging process in other (similar) bodily tissues in general. The data could help in determining impact on astronauts on future missions to the Moon and Mars for example where environmental conditions are more challenging.

Optical Payload for Lasercomm Science (OPALS) Operations: The OPALS ground team successfully downlinked a video file from the ISS to a ground station. During this test downlink, OPALS was at 25 degrees elevation above the horizon and the laser was modulated to 50 mega Hertz while changing the ground station beacon power profile. OPALS aims to demonstrate and test optical communications technologies from the ISS. This is accomplished by transferring video data from the OPALS hardware to a ground receiver at the Jet Propulsion Laboratory’s (JPL’s) Optical Communications Telescope Laboratory (OCTL).

Cygnus Offset Grapple On-Board Training: All 3 USOS crew members participated in this training today in preparation for Orb-2 arrival on July 15. Grapple approaches were practiced where the crew maneuvers the Latching End Effector (LEE) over the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF) pin and pulls the trigger when they enter the grapple envelope.  There were no commands loaded for the LEE during the triggering exercise, so there was no mechanism motion. For the last approach of the session, the crew practiced a hot backup Robotics Workstation System (RWS) transition from the Cupola RWS to the Lab RWS.  After the completion of the grapple practice, the Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) to the Node 2 Nadir Active Common Berthing Mechanism (ABCM) Survey Position.

Advanced Resistive Exercise Device (ARED) Rope Removed & Replaced (R&R): The crew successfully R&Rd the ARED exercise rope as part of nominal maintenance activities which is scheduled approximately every 80 days.

ISS Daily Summary Report – 07/10/14

Posted on July 10, 2014 at 6:08 pm by HQ.
 

Capillary Flow Experiment (CFE) Interior Corner Flow (ICF) Test: Flight Engineer (FE)-6 Gerst set up hardware on the Maintenance Work Area (MWA) and conducted ICF test using the ICF8 hardware which contains a segmented, 50 degree snow cone section. CFE ICF studies capillary flow in interior corners of vessels with various geometries. Structured inside tanks providing interior corners are used in the design of fuel tanks to promote fuel flow to the outlet of the tank in the absence of gravity. Experimental results will provide the necessary boundary conditions as a function of container cross section and fill fraction. The benchmarked theory can be used to improve propellant management aboard spacecraft.

Force Shoes: Gerst performed Treadmill 2 (T2) exercise using the Force Shoes which measured exercise loads experienced during T2 exercise. Ground teams will analyze the loads data and compare it with the data from T2 in order to calibrate the Force Shoes. Once the data is calibrated, the crew will conduct four sessions of Advanced Resistive Exercise Device (ARED) exercise with the Force Shoes to characterize the loads between the crew member and ARED.

Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES) Resonant Inductive Near-field Generation System (Rings): FE-5 Wiseman and Gerst integrated the Rings hardware with the SPHERES hardware and conducted a test session. The investigation uses the SPHERES platform and is designed to demonstrate and test, in a complex environment, enhanced technologies, and techniques related to micro electromagnetic formation flight and wireless inductive power transfer. By advancing the knowledge base with regards to inter-satellite attitude control and wireless power transfer, future systems can expect enhanced attitude control performance between separate satellites and potentially the ability to efficiently transfer power at a distance, possibly alleviating the need for alternate or expendable power sources.

Gradient Heating Furnace (GHF) Software Update:  Gerst performed several setup steps to allow the ground teams to update the GHF with new software in preparation for the Alloy Semiconductor investigation. There was a delay while loading the software, but it was completed successfully.  There are some remaining cleanup steps that will be completed at a later time.  He also removed the Hicari sample cartridge from the GHF in preparation for return on SpaceX-4. After successful completion of the software update, ground teams will conduct a nine-day checkout for Alloy Semiconductor. They Alloy Semiconductor investigation aims to develop a clear understanding of how semiconductor materials grow and crystallize in microgravity. The materials studied are also known to be useful as devices which convert heat into electricity (thermoelectrics). These studies may ultimately shed light on how higher quality crystals may be derived from other materials or incorporated into other devices such as solar cells.

Node 2 (N2) Nadir Centerline Berthing Camera System (CBCS) Installation: In preparation for Orb-2 berthing scheduled next Tuesday, Wiseman installed the CBCS and related avionics required for a visiting vehicle mating to N2 nadir.

ISS Daily Summary Report – 07/11/14

Posted on July 11, 2014 at 5:59 pm by HQ.
 

Orbital-2 (Orb-2) Launch: Launch is currently scheduled for Sunday, July 13 at 11:52 am CDT. Grapple is scheduled for Wednesday, July 16 at 5:37 am CDT followed by berthing to Node 2 (N2) Nadir.  Ingress is scheudled for Thursday, July 17.

Force Shoes: Flight Engineer (FE)-5 Wiseman performed Treadmill 2 (T2) exercise using the Force Shoes, which will measure exercise loads experienced during T2 exercise. Ground teams will analyze the loads data and compare it with the data from T2 to calibrate the Force Shoes. Once the data is calibrated, the crew will conduct four sessions of Advanced Resistive Exercise Device (ARED) exercise with the Force Shoes to characterize the loads between the crew member and ARED.

Burning and Suppression of Solids (BASS)-II Operations: Wiseman conducted 5 thick slab tests for the BASS-II investigation which examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

European Space Agency (ESA) Education Payloads Operations (EPO) Flying Classroom: FE-6 Gerst demonstrated the difference between vacuum and microgravity using a helicopter made out of paper and a pencil, as well as a paper airplane. The EPO will be recorded and downlinked for educational purposes.

Extravehicular Activity (EVA) Tether Inspections:  Commander (CDR) Swanson inspected tethers in preparation for USOS EVAs currently scheduled for August 21st and 29th.

Waste Water Filter Removal and Replacement:  Swanson replaced an expended waste water filter in the Water Processor Assembly (WPA).  This filter is located between the pump/separator Orbital Replacement Unit (ORU) and the waste water ORU.  During the replacement, a valve issue was experienced when the WPA was shutdown.  Ground teams believe the issue response was due to the removal of the Mostly Liquid Separator (MLS) check valve that occurred in January of this year.  The teams may need to revise the WPA shutdown procedures in the future based on this new signature.  The team is proceeding with the nominal standby heat up in preparation for completing a reprocess cycle overnight.

Reboost:  A 61 second .95 meter per second reboost was performed today which provides proper phasing for the 56 Progress 4-orbit rendezvous profile. It also provides margin for a series of low concern conjunctions over the weekend and simplifies operations for Orb-2 rendezvous.

a truly colorful exchange between the cosmonauts and Moscow concerning the content and structure of Russian radiograms--the subject of repeated complaints...

Max "it's clear that crew concerns aren't taken seriously and no one on the ground gives a rats----you know what---..." which received the standard MCC-H response of passing concerns to the "specialists".

Orbital-2 (Orb-2) Launch: Orb-2 launched successfully yesterday, achieved a nominal orbit and the solar array was successfully deployed.  Cygnus has executed several phasing burns to support rendezvous and grapple scheduled for Wednesday, July 16 at 5:39 am CDT followed by berthing to Node 2 (N2) Nadir.  The Orbital team is working through an issue with one of Cygnus Tracking and Data Relay Satellite System (TDRSS) radios, however, the redundant system is working without any issues.  Ingress is scheduled for Thursday, July 17.

Burning and Suppression of Solids (BASS)-II Operations: Flight Engineer (FE)-5 Wiseman conducted flame tests for two black, 0.5 inch diameter acrylic rods for the first time. The BASS-II investigation examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

Advanced Colloids Experiment (ACE)-M-2 Sample Exchange: Commander (CDR) Swanson removed the ACE-M-2 sample from the Fluids Integrated Rack (FIR), mixed it with a Binary Collodial Alloy Test (BCAT) magnet, and reinstalled the samples back into the FIR for ground analysis. In the ACE-M-2 investigation, a model colloidal system is used to observe the microscopic behavior of liquids and gases separating from each other, near the critical point, via a process called spinodal decomposition.

Sally Ride Earth Knowledge Acquired by Middle Schools (EarthKam) Set Up: FE-2 Artemyev and Wiseman set up the Sally Ride EarthKam equipment in the Service Module (SM) window and activated the equipment. Sally Ride EarthKam is a NASA education program that enables thousands of students to photograph and examine Earth from a space crew’s perspective. Using the Internet, students control a special digital camera mounted onboard the ISS. This enables them to photograph the Earth’s coastlines, mountain ranges and other geographic items of interest from the unique vantage point of space. The team at Sally Ride EarthKAM then posts these photographs on the Internet for the public and participating classrooms around the world to view.

European Space Agency (ESA) Gyrotwist Education Payloads Operations (EPO): FE-6 Gerst completed an EPO demonstrating how a gyroscope works in micro-gravity. This EPO was recorded for educational purposes.

High Definition Earth Viewing (HDEV): On Wednesday, July 9th HDEV stopped downlinking science data packets. Ground teams put HDEV in standby mode while operational power was removed from the payload for ten minutes. Once operational power was reapplied to HDEV, science data packets were recovered and video has been restored to the USTREAM website. Ground teams are still investigating the cause of the science data packet interruption.

Pre-Breathe Hose Assembly (PHA) Bag Reconfiguration: In preparation for planned EVAs in August, Swanson reconfigured 2 PHA bags to have 90 feet of pre-breathe hose in each bag and 1 section of coiled 30 foot hose. This is to support of a new pre-breathe hose configuration which reduces the PHA Quick Disconnect (QD) kickload and reduces the length of the of the 120 foot hoses to 90 feet per crew request.

Water Recovery System (WRS): Swanson completed this regularly scheduled maintenance to Remove and Replace (R&R) the WRS recycle tank.

Potable Water Dispenser (PWD) Sample Collect: Gerst collected hot PWD water samples for in flight processing and Total Organic Compound Analyzer (TOCA) analysis and ambient samples for iodine analysis.

Japanese Experiment Module (JEM) Inter-Module Velocity (IMV) Flow Measurement:  Gerst and Wiseman measured air velocity in the JEM Pressurized Module (JPM) overhead aft inlet, starboard aft inlet and starboard forward outlet using the Velocicalc instrument.

ISS Daily Summary Report – 07/15/14

Posted on July 15, 2014 at 5:24 pm by HQ.
 

Burning and Suppression of Solids (BASS)-II Operations: Flight Engineer (FE)-5 Wiseman completed two flame tests for the BASS-II investigation which examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. BASS-II results contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.

Orbital (Orb)-2 Arrival Preparations: In preparation for Orb-2 capture and berthing tomorrow, the following tasks were completed today:
•The 3 USOS crew members conducted On-Board Training (OBT) for Orb-2 attached phase operations, addressing hardware, stowage and attached phase configuration.
•Swanson and Gerst performed the 3rd session of Robotics On-board Trainer (RoBOT) training, completing 2 capture point hold runs which allows practicing free drift timing, malfunction response and nominal rate approaches.
•Swanson set up and checked out the Rendezvous and Proximity Operations Program (RPOP) to prepare the unit to determine the range and range rate of the approaching vehicle. This procedure also covers setup of the Hand-Held Light Intensification Detection and Ranging (LIDAR) if required.
•Gerst routed the Hardware Command Panel (HCP) power and data cables from the JEM Pressurized Module (JPM) through the Cupola and set up the HCP next to the Robotics Work Station (RWS) for Cygnus capture.

Human Research Facility (HRF)2 Supply Kit Resupply: Gerst removed expired limited life items and transferred contents from the HRF consumables kit to the appropriate supply kits. He took photos following completion of the activity.

Potable Water Dispenser (PWD) Filter Remove and Replace (R&R)/Fan Filter Cleaning/Quick Disconnect (QD) Corrective Maintenance: Swanson R&Rd the PWD filter and performed corrective QD maintenance on the PWD galley supply hose inlet QD. The PWD filters will be returned to the ground for refurbishment. Fan filter cleaning is required every 18 months.

Channel 3A Solar Array Wing (SAW) Photos: On June 19, a photo/survey of SAW 3A Flexible Collector Circuit (FCC) was performed and showed damage on particular areas of the array. Today, Wiseman took additional photos of the SAW using digital still camera and telephoto lenses from the Mini-Research Module (MRM)-2.  The images will be downloaded for review by ground teams to determine extent of the damage.

Oxygen Generation Assembly (OGA):  A pressure decay test performed yesterday involved multiple nitrogen purges of the OGA.  Following the test, OGA faulted due to high Hydrogen (H2) readings.  All 3 H2 sensor readings remained high and OGA was configured to Stop.  Ground specialists determined that the signature is likely cause by nitrogen saturation of the H2 sensors.  Nitrogen exposure is known to cause the semiconductor hydrogen sensors to bias towards a reversible high output. Today, ground controllers put OGA in standby to allow oxygen to remove the nitrogren from the oxygen outlet an H2 sensors.  As of the time of this report, the sensors were trending in the right direction and the team expected to be able to reactivate OGA later today.

ISS Daily Summary Report – 07/16/14

Posted on July 16, 2014 at 6:11 pm by HQ.
 

Orbital-2 (Orb-2) Capture/Berthing: The crew successfully captured Cygnus using the Space Station Remote Manipulator System (SSRMS) at 5:39 am CDT. The ground used the Space Station Remote Manipulator System (SSRMS) to maneuver Cygnus into position near the Node 2 Nadir berthing port for Passive Common Berthing Mechanism (PCBM) inspection and berthing. Following berthing, the crew proceeded with post-berthing activities including leak checks, hatch opening and vestibule outfitting and the vehicle is now on ISS power. The crew completed removal of the CBM Controller Panel Assemblies (CPAs) that were originally scheduled for tomorrow.  The crew is scheduled to ingress the vehicle tomorrow.

Sprint Operations: Flight Engineer (FE)-5 Wiseman completed his Flight Day (FD) 45 Sprint Volume of Oxygen Utilized (VO2) protocol using the Blood Pressure (BP)/Electrocardiogram (ECG) hardware. Sprint evaluates the use of high intensity, low volume exercise training to minimize loss of muscle, bone, and cardiovascular function in ISS crewmembers during long-duration missions.

Body Mass Measurements: Commander (CDR) Swanson, Wiseman, and FE-6 Gerst conducted body mass measurements using the Space Linear Acceleration Mass Measurement Device (SLAMMD) hardware. The hardware follows Newton’s Second Law of Motion by having two springs generate a known force against a crewmember mounted on an extension arm with resulting acceleration used to calculate the subject’s mass. The device is accurate to 0.5 pounds over a range from 90 pounds to 240 pounds.
