NASA International Space Station On-Orbit Status 10 August 2016

Rubins and Williams will conduct a spacewalk in August 2016 to install the first International Docking Adapter, the new docking port that will enable the future arrival of U.S. commercial crew spacecraft.

A pair of astronauts tried on U.S. spacesuits this morning ahead of a spacewalk next week. Afterward, the crew explored heart cells, fluid pressure in the head and the eyes and the composition of meteors.

NASA astronauts Jeff Williams and Kate Rubins are due to work outside the International Space Station on Aug. 19 for 6.5 hours. The duo tried on the spacesuits today they will wear during the spacewalk to complete the installation of the first of two International Docking Adapters to the Harmony module. Commercial Crew vehicles are being developed by Boeing and SpaceX that will dock to the new adapters in the future.

Rubins then moved on to observing heart cells with a specialized microscope. The heart cells are derived from stem cells that were manufactured from human skin cells.

Williams joined cosmonaut Anatoly Ivanishin for ultrasound scans and vision checks. That work was part of the Fluid Shifts study that is exploring how the lack of gravity influences head pressure and eye shape possibly affecting an astronaut's vision.

Japanese astronaut Takuya Onishi replaced a hard drive on a laptop computer that collects data on the composition of meteors entering Earth's atmosphere. Cosmonauts Oleg Skripochka and Alexey Ovchinin participated in a study that seeks to improve the ability of a crew member to pilot a spacecraft.

On-Orbit Status Report

Fluid Shifts Operations in the Service Module: With ground team assistance, crewmembers continued Fluid Shifts Imaging exams by conducting the Optical Coherence Tomography (OCT) exam, Ultrasound scans, the Distortion Product Otoacoustic Emission (DPOAE) tests, and a Tonometry exam. This investigation characterizes the space flight-induced fluid shift, including intra- and extravascular shifts, intra- and extracellular shifts, changes in total body water and lower vs. upper body shifts. Results from this investigation are expected to help define the causes of the ocular structure and vision changes associated with long duration space flight, and assist in the development of countermeasures.

Mouse Epigenetics Cage Unit Maintenance: The crew completed standard maintenance activities for the Mouse Epigenetics experiment by refilling the water in the Mouse Habitat Cage Unit located in the Cell Biology Experiment Facility (CBEF). The Mouse Epigenetics investigation studies altered gene expression patterns in the organs of male mice that spend one month in space, and also examines changes in the deoxyribonucleic acid (DNA) of their offspring. Results from the investigation identify genetic alterations that happen after exposure to the microgravity environment of space.

Heart Cells Microscope Operations: The crew set up the Heart Cells microscope, removed the BioCell Habitat from the Space Automated Bioproduct Lab (SABL) and the Multiwell BioCell from the BioCell Habitat and inserted into the microscope before conducting Heart Cells operations. The Heart Cells investigation studies the human heart, specifically how heart muscle tissue, contracts, grows and changes (gene expression) in microgravity and how those changes vary between subjects. Understanding how heart muscle cells, or cardiomyocytes, change in space improves efforts for studying disease, screening drugs and conducting cell replacement therapy for future space missions.

Meteor Hard Drive Change: The crew R&Rd the hard drive in the Meteor Laptop located in the Window Observational Research Facility (WORF) in preparation for upcoming meteor showers. The Meteor investigation provides the first space-based measurement of meteor flux. It also allows for the monitoring of carbon-based compounds. Continuous measurement of meteor interactions with the Earth's atmosphere could also spot previously unforeseen meteor showers.

Dose Tracker: The crew completed entries for medication. This investigation documents the medication usage of crewmembers before and during their missions by capturing data regarding medication use during spaceflight, including side effect qualities, frequencies and severities. The data is expected to either support or counter anecdotal evidence of medication ineffectiveness during flight and unusual side effects experienced during flight. It is also expected that specific, near-real-time questioning about symptom relief and side effects will provide the data required to establish whether spaceflight-associated alterations in pharmacokinetics (PK) or pharmacodynamics (PD) is occurring during missions.

MSG Video File Transfer Issues - Yesterday, the Microgravity Sciences Glovebox (MSG) experienced an issue with the Video Unit Equipment (VUE). Ground teams were unable to access the solid state storage devices during HeartCell video downlink operations. A soft reboot was attempted with no success. A power cycle was then conducted and the drives were recovered. In addition, ground teams are having difficulties in downlinking large files associated with the payload. The HeartCell data is being recorded, so no loss of science at this time. If required, the current work-around is to have the crew utilize a thumb drive to allow the files to be downlink. Currently, the VUE is functional except for downlinking large files. Ground teams are investigating.

Extravehicular Activity (EVA) Preparations: The crew continued preparations for the IDA2 EVA scheduled on August 19. This morning they performed pressurized Extravehicular Mobility Unit (EMU) On Orbit Fit Check Verification (OFV) of EMUs 3003 and 3008 to assess fit and feel of the suits prior to the EVA.
