ISS Daily Summary Report – 8/14/2018

Biological Experiment Laboratory (BioLab):

Спойлер

The crew installed a new BioLab Incubator Door Locking Bolt today. The BioLab is a multiuser research facility located in the Columbus laboratory. It is used to perform space biology experiments on microorganisms, cells, tissue cultures, small plants, and small invertebrates. BioLab allows scientists to gain a better understanding of the effects of microgravity and space radiation on biological organisms.

Human Research (Cell-Free Epigenome (CFE), Marrow and Medical Proteomics):

Спойлер

A 55S crewmember collected Flight Day 60 blood samples for JAXA's CFE, Marrow and Medical Proteomics investigations today.  They also collected a breath sample for Marrow.

[/li]
• For the CFE study, blood samples are collected fr om astronauts and cellular genes are analyzed.  The results provide insight into how human bodies function during space flight.
• Marrow 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.
• The Medical Proteomics investigation evaluates changes of proteins in blood serum, bone and skeletal muscles after space flight, and also supports identification of osteopenia-related proteins. By combining research results for space mice, astronauts and ground patients, proteins related to osteopenia can be identified using the latest proteome analysis technique.  It is anticipated that the use of the marker proteins related to osteopenia will be of benefit in the future for assessing the health of astronauts as well as osteoporosis patients on ground.

Rodent Research-7 (RR-7):

Спойлер

Today the crew restocked and cleaned the rodent habitats. They also stowed fecal pellets and food bar/Habitat swabs in a Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI). The RR-7 investigation examines how the space environment affects the community of microorganisms in the gastrointestinal tract of mice (also known as the microbiota). It also looks at microgravity's effects on multiple physiological systems known to be affected by the microbiota, including the gastrointestinal, immune, metabolic, circadian, and sleep systems. These studies should help explain mechanisms underlying interactions between these systems and the role of the microbiota in these interactions.

Extravehicular Mobility Unit (EMU) Data Recorder (EDaR) Cable Inspection and Install:

Спойлер

Today the crew performed a visual inspection of the connectors on all four cable EDaR cable harnesses to verify the correct clocking of the pins and sockets relative to the connector housing. They also added a visual identifier to each connector to enable quicker inspections in the future and performed a continuity check on three pairs of pins for all four cables to confirm end-to-end integrity of the wiring within the harness. After confirming that the connectors were clocked correctly and had the right connectivity, the crew installed the complete EDaR system into EMU 3003 and 3004. EDaR is a new system that provides real-time data storage from EMU systems and increases the rate in which EMU telemetry is sent to ground controllers.

Public Affairs Office (PAO) Event:

Спойлер

Today Drew Feustel recorded a downlink messages for use during the unveiling of a new area at the Amarillo, Texas airport titled "From Amarillo to Outer Space" honoring the late NASA astronaut and STS-107 Commander Rick Husband. He also recorded messages for release at the 29th Annual Thermal and Fluids Analysis Workshop and the annual meeting of the American Society of Cinematographers.

Intermodule Ventilation (IMV) Flow Measurement Survey:

Спойлер

Ground testing has identified errors in the calibration procedure used during the manufacture of Velocicalc hardware. Recently reported lower than expected airflow measurements indicate that one of the on-orbit probes may be affected and reporting incorrect values. In response, the crew took new airflow measurements today at the LAB Aft Port Fan location using two different Velocicalc Probes, allowing for a comparison between units and verification that the issue is with a probes and not the IMV system. To wrap up the activity, the crew used the spare Velocicalc to retake IMV flow measurements at the locations wh ere suspect measurements were taken last month.

Water Process Assembly (WPA) Ion Exchange Bed Remove and Replace:

Спойлер

Today the crew performed routine maintenance to replace the WPA Ion Exchange Bed. The WPA Ion Exchange Bed removes ionic oxidation byproducts produced in the WPA Catalytic Reactor and provides iodine disinfectant to prevent microbial growth in the Water Storage Tank and Potable Bus.

Mobile Servicing System (MSS) Operations:

Спойлер

Last night robotic ground controllers maneuvered the Space Station Remote Manipulator System (SSRMS) as required to stow the Robotic Offset Tool (ROST) and Special Purpose Dexterous Manipulator. Both ROST and SPDM were used during last week's HTV-7 Battery Remove and Replace (R&R) Get-Ahead tasks.

Russian cosmonaut Oleg Artemyev works outside the International Space Station during a 5-hour, 11-minute spacewalk that took place Aug. 18, 2014, when he was an Expedition 40 Flight Engineer.

Expedition 56 Flight Engineers Oleg Artemyev and Sergey Prokopyev of the Russian space agency Roscosmos are preparing for their exit from the station's Pirs docking compartment airlock at approximately 11:58 a.m. EDT. The spacewalk is planned to last about six hours outside of the International Space Station's Russian segment.

The primary objectives during the spacewalk will be to manually launch four small technology satellites, retrieve material science samples from the hull of the Zvezda service module, and install an experiment called Icarus onto the Russian segment of the space station.

Icarus is a collaborative environmental experiment between the German Aerospace Center (DLR) and Roscosmos to study the migratory patterns of small animals on Earth. It consists of an antenna and GPS hardware to track the movements of animals that have been tagged with small GPS receivers. The experiment may provide data about how animals move from one location to another, how animal population density shifts over time, and how diseases spread.

Coverage of the spacewalk is now underway on NASA Television and the agency's website.

Russian cosmonauts prep for spacewalk
August 15, 2018 | Stephen Clark

Clad in pressurized spacesuits, Russian cosmonauts plan to head outside the International Space Station on Wednesday to hand-release four tiny CubeSats and install hardware for a German experiment to track animal migration.

Russian flight engineers Oleg Artemyev and Sergey Prokopyev are set to head out of the station's Pirs airlock at 1558 GMT (11:58 a.m. EDT) Wednesday for a spacewalk scheduled to last more than six hours. NASA TV will provide live coverage of the excursion, and a live stream is available on this page.

Wednesday's spacewalk will be the third in Artemyev's cosmonaut career, and the first for Prokopyev. It will be the 212th spacewalk dedicated to assembly and maintenance of the International Space Station since 1998, and the 55th staged from the station's Russian segment.

Their tasks include the deployment — by hand — of four CubeSats built by Russian students.

The spacewalkers will carry with them two Tanyusha satellites, each about the size of a small toaster oven, built by students at Southwestern State University with demo payloads to study spacecraft autonomy technology and to measure the vacuum of space. Another pair of SiriusSat CubeSats, assembled by Russian schoolchildren and equipped with particle detectors, will also be with the cosmonauts.

Prokopyev will toss the four nanosatellites into space by hand just outside the Pirs airlock, using a manual release method used on previous Russian spacewalks. The duo will record video of the deployment for Russian media.

The CubeSats were launched earlier this year inside Russian Progress supply ships.

Once the CubeSat deployments are complete, the duo will turn their attention to the installation of antennas and cables for a German-led instrument package to track global animal movements. The equipment will be placed outside the station's Zvezda service module.

Called Icarus, the project aims to reveal changes in migratory routes, animal connections and other animal behavior. The antenna for Icarus was carried aloft in February, and a computer launched on a Russian Progress mission last year to help process the signals coming from tracking units tagged to animals on Earth.

"Icarus is a global collaboration of research scientists that are interested in life on the globe, and once we put together all the information on mobile animals, then we have a different and new understanding of life on Earth," said Martin Wikelski, lead scientist on the Icarus project, director of the Max Planck Institute of Ornithology, and professor the University of Konstanz in Germany.

The spacewalkers will set up an antenna boom, route cables and install the Icarus antenna.

Other tasks planned for Wednesday's spacewalk include the retrieval of materials exposure samples from the hull of the Zvezda service module.

If the cosmonauts have time, they could be assigned a "get-ahead" task of removing and jettisoning a disused Russian experiment package. The jettisoned instrument unit will eventually re-enter Earth's atmosphere.

Airlock is now depressurized; spacewalk has now started by my criterion. Will start with hatch opening by Russian space agency criterion, however.
