NASA International Space Station On-Orbit Status 22 June 2016

Astronaut Jeff Williams works on a pair of U.S. spacesuits inside the Quest airlock.

Commander Jeff Williams continued the ongoing maintenance on U.S. spacesuits throughout the workday on Wednesday. Meanwhile, the Cygnus cargo craft from Orbital ATK re-entered the Earth's atmosphere completing one final experiment.

Williams scrubbed cooling loops and collected water samples from inside U.S. spacesuits ahead of a pair of spacewalks planned for later this year. The main task planned for the first spacewalk will be installing an international docking adapter to the Harmony module. The second spacewalk will see the replacement of batteries as part of maintenance for the International Space Station's power system.

Cygnus has been busy since its release from the station June 14 serving as a platform for science. Its first experiment saw a large fire set inside the vehicle helping scientists understand combustion in space. Earlier this week, a set of nanosatellites was released from Cygnus. Finally, as Cygnus broke apart during its re-entry recorders downlinked data providing insights into the behavior of spacecraft re-entering Earth's atmosphere.

On-Orbit Status Report

Cygnus Re-entry: Cygnus re-entry burn was completed today at 7:45 AM CDT following unberth last Tuesday, June 14.

- The NRCSD-E deployment planned for yesterday succeeded in deploying four of five LEMUR satellites. Several additional attempts were made to deploy the final satellite, but were not successful. Orbital-ATK has confirmed via imagery that the deployer's doors did not open.
- Prior to unberth, the ReEntry Breakup Recorder- Wireless (REBR-W) was configured to activate upon sensing deorbit loads and transmit data automatically. The REBR team has not received data as expectedas of the writing of this report. REBR is a cost-effective system that rides a re-entering space vehicle, records data during the re-entry and breakup of the vehicle, and returns the data for analysis. Understanding how vehicles behave during atmospheric reentry gives future spacecraft developers unique information that can enhance design efficiencies and safety.

62P Thruster Test: Russian ground teams performed a thruster test on 62P. However, only the X axis thrusters fired, the Z and Y axis thrusters did not. Ground teams are investigating, and a re-test of the thrusters is expected on June 27. Following the 62P thruster test, Moscow experienced issues reintegrating the Progress into the control loop. The maneuver back to the Torque Equalibrium Attitude (TEA) was subsequently performed using thruster configuration SM411. Thruster configuration will remain SM411 until Moscow has a forward plan for reintegrating the Nadir Progress. In the meantime, a 62P prop purge is planned for tomorrow.

Dose Tracker: The crew completed entries for medication tracking on an iPad today. This investigation documents the medication usage of crew members 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.

Habitability Human Factors Directed Observations: The crew recorded and submitted a walk-through video documenting observations of an area or activity providing insight related to human factors and habitability. The Habitability investigation collects observations about the relationship between crew members and their environment on the International Space Station. Observations can help spacecraft designers understand how much habitable volume is required and whether a mission's duration impacts how much space crew members need.

Extravehicular Mobility Unit (EMU) Maintenance: The crew spent most of his day performing the following activities to dump and fill EMU 3005, 3008 feedwater tanks to satisfy maintenance requirements for on-orbit stowage. Due to previous EMU off-nominal conditions, steps were included for trend tracking:

- Obtain a feedwater sample from EMU 3005 water tanks for future ground analysis.
- Initiate ionic and particulate filtration of the EMU and Airlock cooling water loops.
- Iodinate EMU Ion Filters and complete a 2-hour EMU iodination.
- Obtain a 250 mL sample of EMU cooling loop water to determine the effectiveness of the Ion Filter in scrubbing EMU and Airlock cooling water. 10 mL of the water sample will be used for a conductivity test. The remainder of the water will be returned to ground for chemical analysis.
- Determine a conductivity measurement for EMU water samples. Each sample will be measured once and two readings will be recorded from the Liquid Conductivity Meter display.
- Regenerate Metal Oxide (Metox) canisters by baking out CO2 in the Metox Regenerator oven.

Station Support Computer (SSC) service pack installation: Ground controllers installed a new service pack on the SSCs onboard ISS.

Node 3 MCA anomaly: This morning, Node 3 MCA experienced an ion pump current spike and shut down. A system restart recovered the MCA functionality.
