ISS Daily Summary Report – 4/18/2017
JEM (Japanese Experiment Module) Airlock (JEMAL) Operations:   They replaced the Multi-Purpose Experiment Platform (MPEP) on the Slide Table (ST) with the Cyclops to support the EVA contingency tie-down during NREP transfer to and from the ST via the JEM Remote Manipulator System (JEMRMS). 

Is someone able to explain this with plain words for a non-English native speaker?

ISS has two main release mechanisms available to deploy payloads from the JEM airlock. Usually, the standard small satellites are released from their containers, which are held by the MPEP, but non-standard payloads use the Cyclops (SSYKLOPS). This MPEP/Cyclops+containers+satellites is brought outside on the Slide Table in the airlock, and maneuvered with the JEM robotic arm to the "launch" position. Once the satellites are away, the container+MPEP/Cyclops is cycled back inside through the Slide Table and airlock.

The NREP is a payload installed in the JEM-EF (exposed facility, the "porch" of ISS) since August. I am not entirely sure why, but it looks this facility is being brought inside - I imagine because of OA-7's arrival with some experiments that need to be loaded up in NREP for exposure. Cyclops is able to have it tied down by EVAers in the case of a contingency prevents NREP from having it secured to either the slide table in the airlock or the JEM-EF's facility attachment points, and apparently MPEP doesn't offer the same capability.

Thank you for your detailed answer.
It is the first time that I heard about a contigency EVA in connection with installation/deinstallation on the JEM-EF.

ISS Daily Summary Report – 4/19/2017

Posted on April 19, 2017 at 4:00 pm by HQ.
 

Fluid Shifts Dilution Measurements:  The 49S subjects continued their Return minus 45 (R-45) Fluid Shifts Dilution Measurements activities today, collecting saliva, blood and urine and inserting them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer. Throughout the day, the crew will perform more collections, storing them in MELFI as well.  Fluid Shifts is a joint NASA-Russian experiment divided into Dilution Measurements, Baseline Imaging, and Baseline Imaging with Chibis (Lower Body Negative Pressure). The Fluid Shifts experiment investigates the causes for severe and lasting physical changes to astronaut’s eyes.  Because the headward fluid shift is a hypothesized contributor to these changes, reversing this fluid shift with a lower body negative pressure device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and to prevention of eye damage.

European Space Agency (ESA) Active Dosimeter Swap:  The crew replaced an Active Dosimeter Mobile Unit and downloaded the recorded data to an Active Dosimeter Personal Stowage Device. The European Crew Personal Active Dosimeter is worn by European ISS crewmembers on orbit to measure radiation exposure. This device, coupled with other dosimeters in the Columbus Laboratory, provides radiation dosage information that can be used to support risk assessment and dose management. The goal is to enable the verification of radiation monitoring systems for future medical monitoring of crewmembers in space.

Japanese Experiment Module (JEM) Airlock (JEMAL) Operations:  The crew depressed the airlock and vented remaining air in preparation for NanoRacks External Platform (NREP) operations next week.

Dose Tracker: The crew completed a medication tracking entry in the Dose Tracker application that runs on an iPad. Dose Tracker 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 investigation is expected to provide anecdotal evidence of medication effectiveness during flight and any unusual side effects experienced. 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 or pharmacodynamics is occurring during missions.

Mobile Serving System (MSS) Operations:  Yesterday afternoon, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) into position for the start of the Orbital ATK-7 (OA-7) Offset Grapples Practice Session. They then powered up the MSS in the Hot Backup configuration for the crew to practice maneuvering the SSRMS into the grapple envelope of the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF). They performed this several times and then performed a final run during which Ground Controllers safed the SSRMS to simulate a failure. The crew recovered by switching from the Cupola Robotic Workstation (RWS) to the Lab RWS and backing the SSRMS away. After the Offset Grapples Practice session, Ground Controllers reconfigured the MSS for nominal operations and maneuvered the SSRMS to a park position.  Finally, Robotic Flight Controllers performed a Direct Drive test of the Wrist Roll Joint (1) for mechanism health trending. Data collected will be compared with the data collected for joint 7.

On-Board Training (OBT) Robotic Onboard Trainer (RoBOT): Following yesterday’s successful launch of OA-7 and planned capture/berthing this Saturday, the crew completed a training session utilizing the RoBOT. They performed three Capture Point hold runs and numerous two meter runs. They also completed a self-study session.

ISS Daily Summary Report – 4/20/2017

Posted on April 20, 2017 at 4:00 pm by HQ.
 

50 Soyuz (50S) Launch/Dock: 50S launched from the Baikonur Cosmodrome today at 2:13AM CDT with Fyodor Yurchikhin and Jack Fischer aboard and docked in the automated mode to the Mini Research Module (MRM)-2 at 8:24AM CDT.  Following hatch opening at 10:05AM CDT, all crew members participated in a crew safety briefing to review emergency actions and roles and responsibilities in the event of a depressurization, fire or toxic release. With the arrival of these crewmembers the ISS is in 5-crew operations.

Electromagnetic Levitation (EML) Sample Coupling Electronic (SCE) Changeout: The crew swapped SCE Chambers in the Experiment Module of the EML today.  The SCE measures electrical resistivity of samples inside the EML which contains 4 inserts for Electromagnetic Levitation samples. The experiment samples are installed in a dedicated Sample Chamber that is attached to EML and will be replaced by new Sample Chambers for new experiment batches.

Microgravity Experiment Research Locker / INcubator (MERLIN) 2 Health and Status Troubleshooting:  The crew performed troubleshooting steps to recover Health and Status data which terminated on March 30, 2017. The crew then attempted to reboot the computer but the unit failed to reboot and is no longer cooling. A replacement MERLIN will arrive on OA-7.

Orbital 7 (OA-7) Arrival Preparations: In preparation for this Saturday’s OA-7 arrival, the crew deployed and performed a checkout of the Centerline Berthing Camera System (CBCS) on the Node 1 Nadir hatch. Video from the CBCS is used to aid Flight Controllers during Visiting Vehicle mating operations.

Urine Processing Assembly (UPA) Status: Overnight, the UPA experienced a fault due to apparent belt slippage in the DA. This signature has been seen on previous DAs, however it is the first occurrence since installing this ORU on April 13th. Ground teams are discussing the signature and forward plan for restarting the UPA.

Solar Array Wing (SAW) 3B Hinge Tear: During a review of imagery taken during Tuesday’s routine solar array inspection, ground teams identified a ~6-7 inch “tear” on one of the hinges of the 3B solar array blanket. The damage was reviewed prior to 50S docking and it was determined that, given the extent of the damage, there was no concern of propagation of that damage based on the expected loading conditions for the event. Followup imagery will be requested to assess the level of damage incurred and determine whether any additional actions will be required.

JAXA Protein Crystal Growth (PCG) #12 Installation and Execution:  The crew installed and configured the JAXA PCG#12 canisters in JEM Ryutai rack. This experiment will run until removal for return on 49S.  The two canisters contain a total of 47 protein samples that were prepared by Russian and Japanese researchers from universities, national research institutes, and the private sector. The purpose of this activity is to obtain high quality protein crystals in the microgravity environment at a constant temperature for about 6 weeks. Results may contribute to the development of drugs for multidrug-resistant bacteria, Alzheimer’s disease, muscular dystrophy and periodontitis. They will also aid in the development of a blood substitute and biosensor.

Orbital 7 (OA-7) Arrival Preparations: In preparation for OA-7 capture and berthing this Saturday, the crew completed the following:
•Reviewed Cygnus attached phase configuration, hardware, and stowage.
•Relocated Portable Computer System (PCS) and cables from Japanese Experiment Module Pressurized Module (JPM) Utility Outlet Panel (UOP) to the Lab UOP.
•Completed a Robotics Onboard Trainer (RoBOT) session to practice Capture Point hold runs and 2 meter runs.
