RIA Novosti quotes specialists as saying that a delay until July 7 or 8 is now almost inevitable, but a formal decision is still pending. The landing of Malenchenko, Peake and Kopra will probably be moved to July 2. However, the dates may change depending upon the exact orbital parameters of the ISS.

The launch delay for Soyuz-MS-01 is now official, but the landing of Soyuz TMA-19M remains on schedule.

Quote
MOSCOW, June 6. /TASS/. Russia’s government commission has made a decision to postpone the launch of the manned Soyuz MS spacecraft to the International Space Station from June 24 till July 7, the state-run space corporation Roscosmos has said.

"For enhancing the safety of the newly modified spacecraft Soyuz MS’s flight to the ISS it has been decided to carry out more tests of software. The state commission has made a decision to launch the Soyuz FG rocket carrying the Soyuz-MS spacecraft till 04:36 Moscow time on July 7, 2016," the Roscosomos press-service has said.

The launch of another cargo spacecraft, Progress MS, has been delayed, too. Originally it was due on July 7. Now it has been scheduled for July 17.

Earlier, a source in the space rocket industry told TASS there was a possibility the launch of Soyuz MS may have to be postponed. He explained that specialists advised against hurrying with the launch as there was the risk of a glitch in the control system and problems while docking the new series spacecraft to the ISS. The Soyuz MS is to deliver to the ISS Russia’s Anatoly Ivanishin, NASA’s Kathleen Rubins and Japan’s Takuya Onishi.

The State Commission has decided not to put off the return of a Soyuz-TMA-19M spaceship with 3 ISS crew members onboard to Earth from June 18 to a later date,  Roscosmos said.
"Soyuz TMA-19M is to land at 12:12 Moscow time on June 18, 2016," the press service said.
A number of media outlets reported earlier that the ISS crew could be asked to extend their stay at the station because of a possible delay of the launch of a new manned spaceship Soyuz-MS. But a source in the Russian rocket and space industry told TASS that experts had recommended not to postpone the ISS crew’s return. Soyuz TMA-19M will take Russian Yuri Malenchenko, American Timothy Copra and Briton Timothy Peak back to Earth.

Why not delay their return surely halving the crew on ISS with no replacements on hand will impact science delivery. I would think that all sides should have a say in this not just the Russian?

Are there any good overviews of the Soyuz-MS upgrades?
Additional upgrades beyond those mentioned below will be introduced additional MS spacecraft as each new one is built. It is not guaranteed as to which flights will see additional upgrades applied. Soyuz MS(-01(No. 731)) is the first crewed spacecraft to have the below modifications and upgrades over the previous versions.

From ROSCOSMOS and RSC Energia press services is the following overview of the first Spacecrafts MS:
The new-series transportation spacecraft Progress MS and Soyuz MS designed and built by RSC Energia were developed as a result of a radical upgrade of Progress M and Soyuz TMA spacecraft. The onboard command radio system Kvant-B was replaced with an integrated command and telemetry system with an additional telemetry channel. The new command radio link will make it possible to receive signals via relay satellites Luch-5, which will significantly increase the radio coverage zone for the spacecraft – up to 70% of an orbit.

The new-model spacecraft are equipped with an advanced onboard radio system for rendezvous and docking Kurs-NA. As compared with an earlier model, Kurs-A, it has improved mass and dimensions parameters and makes it possible to delete from the spacecraft hardware configuration one of the three sets of radio antennas. Instead of the analog TV system Klyost, the spacecraft will use a digital TV system, which will make it possible to maintain communications between the spacecraft and the station via a space-to-space RF link.

Also included into the onboard equipment of the Soyuz MS and Progress MS series spacecraft to replace the equipment that is being phased out of production is a new Digital Backup Loop Control Unit BURK developed by RSC Energia, an upgraded Rate Sensor Unit BDUS-3A and a LED headlight SFOK. Thanks to the use of new ground and onboard radio systems, it became possible to use state-of-the-art data transmission protocols, which resulted in improved operational stability of spacecraft control system.

Most of the engineering solutions incorporated into the design of Soyuz MS and Progress MS spacecraft will be used in the design of the new-generation Crew Transportation Spacecraft (CTS), which is currently under development at RSC Energia.

A cynic might say because two USOS crew members are coming home thus impacting the science and operations on that part of the station far more.

Their mission was already extended once, and there are a lot of moving parts in the ISS VV scheduling. They are also edging up on the Soyuz on-orbit lifetime limit. But hey, if the people actually running the program made a trade that isn't the "obvious" choice to casual outside observers, it's probably a malicious conspiracy, right?

ISS Daily Summary Report – 06/20/16

Posted on June 20, 2016 at 5:36 pm by cosbourn.
 

Direct Current To Direct Current (DDCU) LA1A Trip: Last Thursday, DDCU LA1A tripped off due to a ~40 amp overcurrent. Parallel DDCU LA4A was already off for Battery 4A conditioning. A Failure Investigation Team (FIT) recommended the crew perform troubleshooting steps including rotation of the rack and visual inspection of the DDCUs, wire harnesses, and the Secondary Power Distribution Assembly (SPDA).  The crew also performed multimeter measurements on both DDCU outputs on the face of the DDCU as well as on the output cable leading to downstream wiring for indications of a fault. Following the troubleshooting, another FIT was held and the recommendation was to R&R DDCU LA1A which the crew completed this morning. Both DDCUs and Pressurized Mating Adapter (PMA)2 shell heaters were powered on and are operating nominally.  CEVIS has been reinstalled.  Ground teams have recovered most affected loads with a few remaining items to be repowered tonight.

Multi-Omics Operations:  The crew supported the Japan Aerospace Exploration Agency (JAXA) Multi-Omics investigation by collecting samples and inserting them in the Minus Eighty-degree Freezer for ISS (MELFI). The investigation evaluates the impacts of space environment and prebiotics on astronauts’ immune function by combining the data obtained from the measurements of changes in the microbiological composition, metabolites profiles, and the immune system.

NeuroMapping Operations: The crew set up the hardware and performed this experiment, including testing in both a “strapped in” and ”free floating” body configuration. The investigation studies whether long-duration spaceflight causes changes to the brain, including brain structure and function, motor control, and multi-tasking abilities. It also measures how long it takes for the brain and body to recover from changes. Previous research and anecdotal evidence from astronauts suggests movement control and cognition can be affected in microgravity. The NeuroMapping investigation performs structural and functional magnetic resonance brain imaging (MRI and fMRI) to assess changes that occur after spending an extended period on the ISS.

Ammonia Measurement Kit Chip Measurement System (CMS) Battery Changeout: The CMS draws a small amount of current even while inactive, therefore the batteries must be changed periodically to ensure the CMS will activate in an emergency. During this procedure the crew verified that the CMS would have activated using the installed batteries near end-of-life, then replaced them.

Treadmill 2 (T2) Monthly Maintenance: The crew completed this regularly scheduled maintenance to inspect the bungee shackle key mount witness marks, Y-Axis isolators, two boot snubbers, and all four snubber arms for signs of free play.

ISS Daily Summary Report – 06/21/16

Posted on June 21, 2016 at 4:00 pm by HQ.
 

NanoRacks CubeSat Deployer- External (NRCSD-E) Operations: Following Cygnus unberth last week, today NRCSD-E conducted post departure satellite deployments prior to Cygnus re-entry tomorrow, June 22. This set of cubesats includes 3 deployment silos containing a total of 5 LEMUR satellites.  Two out of three silos (four out of five satellites) were successfully deployed. The Orbital team downlinked and reviewed imagery to ascertain why one of the CubeSats did not deploy. Further troubleshooting is ongoing. The LEMUR satellites are equipped with payloads to provide two primary data products: AIS Data (Maritime Domain Awareness) and GPS-RO Data (Weather). NRCSD-E is a mechanical separation system for small U-class satellites designed specifically to interface with the Orbital-ATK Cygnus cargo resupply vehicle. It consists of an array of up to six individual 6U deployers contained within one mechanical housing that releases the CubeSats from Cygnus after it has completed its primary mission and departed the ISS.

Multi-Omics Operations:  The crew supported the Japan Aerospace Exploration Agency (JAXA) Multi-Omics investigation by collecting saliva samples and inserting them into the Minus Eighty-degree Freezer for ISS (MELFI). The investigation evaluates the impacts of space environment and prebiotics on astronauts’ immune function by combining the data obtained from the measurements of changes in the microbiological composition, metabolites profiles, and the immune system.

Extravehicular Mobility Unit (EMU) Swap: In preparation for tomorrow’s loop scrub activities, the crew retrieved EMUs 3005 and 3008 from the Crewlock and temp stowed them. He then removed EMU 3010 from the forward EMU Don/Doff Assembly (EDDA) and installed EMU 3008. He removed EMU 3003 from the aft EDDA and installed EMU 3005.

Microbial In-Flight Water Operations: The crew performed analysis of water samples collected earlier to determine water quality onboard the ISS. The focus was on microbial and coliform detection.

On-Board Training (OBT) 46 Soyuz (46S) Emergency Drill: The crew completed an emergency egress drill for proficiency in the event of an ISS emergency requiring crew departure. The OBT is scheduled after 12-14 weeks aboard the ISS and once every two and one half months thereafter.

ISS Daily Summary Report – 06/22/16

Posted on June 22, 2016 at 4:00 pm by HQ.
 

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.

Cosmonauts onboard ISS are to try out the manual control system of Progress MS

June 24, 2016

In accordance with the International Space Station (ISS) mission plan, on July 1, 2016 a trial test will be run on Progress MS cargo spacecraft of the upgraded system for remote control of the spacecraft – TORU (teleoperator control mode). The trial is necessary in order to complete the program of flight tests of Progress MS cargo spacecraft.

In the course of the scheduled tests the cargo spacecraft will depart at 08:35 Moscow Time from the docking compartment Pirs (DC-1) of the ISS to the distance of about 200 meters for a comprehensive check of TORU operation. The control of the cargo spacecraft will be assumed by the Roscosmos cosmonauts currently staying onboard the ISS Alexei OVCHININ and Oleg SKRIPOCHKA.

The final stage in the testing will be to re-attach the Progress MS to the station. The docking in the manual control mode is scheduled for July 1, 2016 at 09:10 Moscow Time to the module DC-1 Pirs of the ISS.

The TORU system is a system for remote manual control of spacecraft motion, and provides control via two joysticks and a control panel onboard the ISS.One of the joysticks controls the spacecraft translation, the other controls its attitude.The system also includes a TV camera installed on the spacecraft that is being docked.

The new-series transportation spacecraft Progress MS and Soyuz MS were developed as a result of a radical upgrade of Progress M and Soyuz TMA spacecraft.

The onboard command radio system Kvant-B was replaced with an integrated command and telemetry system with an additional telemetry channel. The new command radio link will make it possible to receive signals via relay satellites Luch-5, which will significantly increase the radio coverage zone for the spacecraft – up to 70% of an orbit.

The new-model spacecraft are equipped with an advanced onboard radio system for rendezvous and docking Kurs-NA. As compared with an earlier model, Kurs-A, it has improved mass and dimensions parameters and makes it possible to delete from the spacecraft hardware configuration one of the three radio antennas.

Instead of the analog TV system Klyost, the spacecraft will use a digital TV system, which will make it possible to maintain communications between the spacecraft and the station via a space-to-space RF link.

Also included into the onboard equipment of the Soyuz MS and Progress MS series spacecraft to replace the equipment that is being phased out of production is a new Digital Backup Loop Control Unit developed by RSC Energia, an upgraded Rate Sensor Unit BDUS-3A and a LED headlight SFOK.

Japanese Experiment Module (JEM) Airlock (JEMAL) Exposed Experiment Handrail Attachment Mechanism (ExHAM) #1-2 Operations: Following the JEM Remote Manipulator System (JEMRMS) Small Fine Arm (SFA) retrieval and detachment of 14 ExHAM #1 samples from the Handhold Experiment Platform last week, today the new samples were installed. ExHAM #1-2 is the first return and sample exchange mission of the 1-year exposed ExHAM #1 which contain 17 samples and 14 will be returned on SpX-9. ExHAM is a cuboid mechanism equipped with a fixture on the upper surface for grappling by the JEMRMS SFA, and has components on the under surface for attaching the ExHAM to the handrail on the JEM Exposed Facility.

Microchannel Diffusion Glacier Sample Retrieve and Diffusion Plate Changeout: Samples were retrieved from the Glacier and temporarily stowed to allow the samples to thaw. The Diffusion Plate in the LMM (Light Microscopy Module) AFC (Auxiliary Fluids Container) was removed and exchanged with another plate. Microchannel Diffusion takes advantage of microgravity to study interactions of medicine, biology, computer science and many other fields that benefit from nanotechnology at slightly larger scales, providing a new understanding of particle flows at the nanoscale.

Habitability Human Factors Directed Observations: The crew completed a Habitability session by recording and submitting 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.

Microbial In-Flight Water Operations: On Tuesday the crew collected water samples to determine water quality onboard the ISS with the focus on microbial and coliform detection. Today he visually analyzed Coliform Detection Bags and Microbial Capture Devices following the required 48 hours of incubation.

MEDIA ADVISORY M16-075

NASA TV to Air Russian Cargo Ship Movement at Space Station
 
A Russian cargo ship currently docked to the International Space Station will undock for a short test flight on Friday, July 1. NASA Television coverage will begin at 1:15 a.m. EDT.

The Progress 62 cargo ship will automatically undock from the Pirs Docking Compartment of the space station and manually be guided in to re-dock. The maneuver will begin with undocking at 1:36 a.m. and take approximately 30 minutes, with re-docking planned for 2:10 a.m.

This activity will test a newly installed manual docking system inside the station’s Russian segment. The resupply ship will back away to a distance of about 600 feet (about 183 meters) from the station, at which point Expedition 48 cosmonauts Alexey Ovchinin and Oleg Skripochka of the Russian space agency Roscosmos will take manual control of the spacecraft. They will use a workstation in the Zvezda Service Module to “fly” the Progress back to a linkup with Pirs.

The system test will include verification of software and a new signal converter incorporated in the upgraded manual docking system for future use in both Progress and piloted Soyuz vehicles in the unlikely event the “Kurs” automated rendezvous in either craft encounters a problem.

Progress 62 arrived at the station Dec. 23, 2015 with more than three tons of food, fuel and supplies, and will undock for the final time at 11:48 p.m. Saturday, July 2. The spacecraft, loaded with trash, will be deorbited by Russian flight controllers to burn up in the Earth’s atmosphere over the Pacific Ocean.

 The mention of the Mir collision is a neat coincidence- last night on the radio I heard a fantastic BBC bit [taking a break from Brexit] with Mike Foale recounting the incident.

ISS Daily Summary Report – 06/24/16

Posted on June 24, 2016 at 4:00 pm by HQ.
 
Multi-Omics: The crew checked the remaining Fructooligosaccharide (FOS) packages and stowed the Fructooligo Bag for the Japan Aerospace Exploration Agency (JAXA) Multi-Omics investigation. The Multi-Omics analysis of human microbial-metabolic cross-talk in the space ecosystem evaluates the impacts of space environment and prebiotics on astronauts’ immune function by combining the data obtained from the measurements of changes in the gut microbiological composition, metabolites profiles, and the immune system.

Expedite the Processing of Experiments to Space Station (EXPRESS) Rack-3 Laptop Computer (ELC) Operations: The EXPRESS Laptop Release 10 disk was removed from the EXPRESS Rack-3 Laptop and installed in the EXPRESS Rack-5 Laptop in preparation for upcoming European Modular Cultivation System (EMCS) maintenance activities.

Packed Bed Reactor Experiment (PBRE) Hardware Stow: Following completion of 4 weeks of PBRE operations, the crew spent the majority of his day de-configuring and stowing the PBRE hardware. The PBRE was used to study the behavior of gases and liquids when they flow simultaneously through a column filled with fixed porous media. The porous media or “packing” can be made of different shapes and materials and are used widely in chemical engineering as a means to enhance the contact between two immiscible fluid phases (e.g., liquid-gas, water-oil, etc.). Packed columns can serve as reactors, scrubbers, strippers, etc. in systems where efficient interphase contact is desired, both on Earth and in space. The next operations are planned for this December.

ISS Maneuver to Solar Attitude: Yesterday the ISS performed a CMG attitude maneuver to a slightly biased attitude that allows the Solar payload on Columbus to maintain visibility of the sun.  ISS will stay in the Solar attitude until June 27.

ISS Daily Summary Report – 06/27/16

Ultrasonic Background Noise Test (UBNT): The crew replaced batteries and transmitted data by closing out the Station Support Computer (SSC’s) Distributed Impact Detection System (DIDS) software and removing the UBNT hardware. UBNT detects high-frequency sounds generated by hardware on the U.S.-built portions of the ISS. Identifying sources of noise will aid in development of a leak locating system which would detect the high-pitched sound of air leaking through a pressurized wall. To detect leaks, the system would have to differentiate between harmless background sounds and a potentially dangerous air leak.

LAB Major Constituent Analyzer (MCA) Mass Spectrometer Assembly (MSA) Troubleshooting: In December 2014, the crew installed new Orbital Replacement Units ORU1, ORU2, and ORU8 in the Lab MCA.  When the Lab MCA was restarted, there was no communication with ORU2.  Today the crew attempted to isolate the problem to either ORU2 or the connector it mates with on the MCA drawer.  The crew reported no visible damage to either side of the ORU2 connector interface. He performed resistance checks on sockets on the drawer side connector saver and found that four of the sockets tested had lower than expected resistances.  To address one potential cause of this problem, the crew replaced ORU4, the Low Voltage Power Supply, and repeated the resistance check on the previously failed sockets.  The resistances of the sockets did not change so the original ORU4 was reinstalled.  The rack has been closed out with ORU2 and ORU8 uninstalled. Teams are meeting to discuss the forward plan.  The Node 3 MCA is operating nominally.

Remote Power Controller RPCM LA2A3B-G RPC 2 Trip: This morning the RPC that provides power to the Fluids Integrated Rack (FIR) Primary Power feed tripped.  At the time of the trip, ground teams were activating FIR for science operations.  The crew reported no smoke odor and Compound Specific Analyzer Combustion Products (CSA-CP) readings were zero.  A current spike high enough to trigger an RPC trip was not visible in the 50 Hz Direct Current to Direct Current Converter Unit (DDCU) current data, however, it is possible that the current spike was rapid enough to not be sampled at 50 Hz.  After analysis of the system showed that the suspect components would be isolated if the main power feed was not used, the rack was successfully repowered using the auxiliary power feed.  The auxiliary power feed will allow the MicroChannel Diffusion to achieve their science goals, and troubleshooting on the main power feed will occur after that payload’s objectives are complete.
