ISS Daily Summary Report – 5/15/15

Posted on May 15, 2015 at 4:33 pm by HQ.
 

Fluid Physics Experiment Facility (FPEF) Marangoni Deformation (MD) Removal: Cristoforetti removed the MD10 from the FPEF in preparation for Dynamic Surf-3 scheduled in Increment 45.  Fluid convection observations are performed of a silicone oil liquid bridge that is generated by heating the one disc higher than the other within the FPEF. By observing and understanding how such fluids move, researchers can learn about how heat is transferred in microgravity, and ultimately drive the design and development of more efficient fluid flow based systems and devices.

Actiwatch Reconfiguration: Kelly reconfigured his and Kornienko’s SLEEP Actiwatches.  He verified the remaining battery life and modified the settings to match the data collection intervals required for the experiment. The Sleep ISS-12 experiment monitors ambient light exposure and crew member activity, and collects subjective evaluations of sleep and alertness, to examine the effects of space flight and ambient light exposure on sleep during a year-long mission on the International Space Station (ISS).

Microbial Observatory-1 Sample Collection: Virts performed surface and air sampling using various devices in multiple locations and photograph each location prior to sample collection. This activity is to characterize the types of microbial populations on ISS.  The samples will return on SpaceX-6.

ISS Reboost: The ISS is scheduled to perform a reboost tonight using 58 Progress (58P) thrusters. Planned burn duration is 15 minutes, 1 second with a Delta-V of 1.64 meters/second. This reboost, combined with a planned burn on June 7, targets phasing requirements for 41 Soyuz (41S) landing currently scheduled for June 11.

Mobile Servicing System Operations: Today, the Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) to prepare to stow Robotic Micro-Conical Tool 2 (RMCT2).  SPDM Arm 1 was then used to maneuver RMCT2 over the Tool Holster Assembly (THA) and stow the RMCT.  After releasing the RMCT, Arm 1 was configured to a stow configuration.  The Robotics Ground Controllers are currently maneuvering SSRMS to place the SPDM on Mobile Base System (MBS) Power Data Grapple Fixture 2 (PDGF2).  They will then release SPDM and maneuver SSRMS to a park position.

Node 3 Carbon Dioxide Removal Assembly (CDRA) In Flight Maintenance (IFM) Update –Yesterday, the crew successfully replaced the N3 CDRA blower fan.  Ground teams completed leak checks on beds 1 and 2 today.  No leaks were detected on vacuum side, however, data indicates a possible leak on the air side. No impacts expected to CO2 removal and plan is to leave Node 3 CDRA operational while engineering continues to monitor.  Lab CDRA will be deactivated tonight. CO2 levels remain low.

The Station also has a set of thrusters on the Zvezda module can be employed. However, they are mainly reserved for when a Visiting Vehicle can’t conduct the task, as the requirement of protecting the Station’s propellant stores is paramount.

I thought the reason ISS tries not to use Zvezda engines is due to limited number of cycles they are designed for?

Presently, Progress M-26M is docked on Zvezda. If Zvezda's engines were ignited, they would destroy Progress.

I try to find other reboost failures in ISS history. I've found one on November 29th, 2006 (Progress M-58's engines stopped because of ISS new configuration after STS-115).

I'm pretty sure there was another case more recently, but I do not find it !!

A more recent failure in a ISS reboost burn using a the SM Main Engines was on January 14 2009 when incorrectly loaded data caused serious vibrations through-out the station structure.

Updated the article as NASA gave info saying M-26M DID fire the thrusters on the first attempt, but aborted one second in.

https://blogs.nasa.gov/spacestation/2015/05/18/station-orbit-boosted-sunday-night-eye-science-on-monday/

"A previous attempt on Friday evening was aborted one second into the burn automatically by the Progress vehicle. Russian flight controllers identified an issue with one of the eight thrusters on the spacecraft that was disabled for Sunday’s backup attempt."

There are two sets of DPO engines on Progress for a performing of ISS orbit's boosts. Each set is including four engines. After a finding of problem with one engine they disabled not only this engine but all set of four engines which it included in. So yesterday's reboost was performed by four engines of other set. That is why Monday's reboost was two times longer than Saturday's reboost.

ISS Daily Summary Report – 05/18/2015

Posted on May 18, 2015 at 5:36 pm by HQ.
 

Fluid Shifts Before, During and After Prolonged Space Flight and Their Association with Intracranial Pressure and Visual Impairment (Fluid Shifts): Kelly begun his Flight Day (FD) 45 Fluid Shifts Dilution Measurements today.  Upon wakeup he collected baseline saliva, blood and urine and inserted them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer.  Throughout the day, he performed more urine, blood, and saliva collections, inserting those samples into MELFI as well.  The Dilution Measurements are the first part in the series of FD45 Fluid Shifts measurements. Next week, Kelly and Kornienko will be performing their Baseline Imaging using the ultrasound.  The third portion of the Fluid Shifts experiment involves utilization of the Russian Chibis (Lower Body Negative Pressure – LBNP) during ultrasound measurements.  Fluid Shifts 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 investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Ocular Health: Virts and Cristoforetti performed their Return-30 (R-30) Ocular Health sessions.  Each crew acted as the Crew Medical Officer (CMO) for each other’s tonometry session, and Cristoforetti assisted Virts in collecting his blood pressure.  The crew also performed vision tests and questionnaires.  The Ocular Health protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines.

Dragon Release On-Board Training (OBT): In preparation for SpX-6 unberth scheduled this Thursday, today Virts and Kelly performed proficiency training on the Dragon departure profile, departure crew procedures, and crew interfaces for monitoring and commanding Dragon.  The lesson walks through the steps in the departure procedures and provides representative Remote Work Station (RWS) and Portable Computer System (PCS) screenshots for each step. The lesson also provides an overview of the Dragon commands available to the crew via the Crew Command Panel (CCP). The crew will also perform Dragon Robotics On-Board Trainer (RoBOT) OBT.

ISS Reboost: The ISS reboost attempt Friday night using 58 Progress (58P) thrusters was aborted within the first second of the burn. MCC-M confirmed the abort was due to Rendezvous and Docking (R&D) Thrusters #1 on Manifold #1 unable to pass an automatic readiness check at the time of ignition.  A second attempt to reboost ISS was successfully performed overnight on Sunday utilizing Manifold #2. The burn duration was 32 min and 3 sec. The planned delta velocity (dV) was 1.75 m/s, but the actual dV was 1.89 m/s. This difference was within family to previous reboosts in this configuration and is not expected to cause any long-term trajectory impacts. This reboost set up phasing for 41S landing scheduled on June 11th 2015.   MCC-M will be investigating the issue with Thruster #1 on Manifold #1.

Japanese Experiment Module (JEM) Power Strip (PS)-120 Junction Box: Today, Virts installed the JEM PS-120 Junction Box at the JPM1F7 location. The newly installed junction box will provide crews the ability to have a total of eight simultaneous 120V loads plugged in.

JEM Network Storage (NeST):  Virts installed the NeST, which will provide more network storage capability on JEM LAN during Ku LOS period.  This hardware was required to be installed to accommodate the PS-TEPC, scheduled to arrive onboard later this year.

ISS Daily Summary Report – 05/19/15

Posted on May 19, 2015 at 4:59 pm by HQ.
 

USOS Crew Reduced Duty Day: Today was a reduced duty day for the USOS Crew as a result of sleep shifting in preparation for SpaceX-6 departure on Thursday, 21 May 2015.

Fluid Shifts Before, During and After Prolonged Space Flight and Their Association with Intracranial Pressure and Visual Impairment (Fluid Shifts): Kornienko begun his Flight Day (FD) 45 Fluid Shifts Dilution Measurements today, with the assistance of Padalka as his Crew Medical Officer (CMO).  Upon wakeup he collected baseline saliva, blood and urine and inserted them into Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI) prior to ingesting a Sodium Bromide (NaBr) tracer.  Throughout the day, he performed more urine, blood, and saliva collections, inserting those samples into MELFI as well.  The Dilution Measurements are the first part in the series of FD45 Fluid Shifts measurements. Next week, Kelly and Kornienko will be performing their Baseline Imaging using the ultrasound.  The third portion of the Fluid Shifts experiment involves utilization of the Russian Chibis (Lower Body Negative Pressure – LBNP) during ultrasound measurements.  Fluid Shifts 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 investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Ocular Health: Virts with Cristoforetti as his CMO, and ground remote guidance, performed his Optical Coherence Tomography (OCT) exam to measure retinal thickness, volume, and retinal nerve fiber layer as required for his Return-30 (R-30) Ocular Health sessions.  Later in the day, he executed his fundoscope exam to obtain images of the retinal surface, again with Cristoforetti and ground assistance.  The Ocular Health protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines.

Commercial Orbital Transport Services (COTS) UHF Communication Unit (CUCU) Checkout:  In preparation for the upcoming SpaceX-6 departure, Kelly worked with ground teams to activate the CUCU System and successfully performed a Crew Command Panel (CCP) checkout. CUCU provides a command and telemetry communications link between ISS and Dragon during free flight operations in the vicinity of ISS. 

Dragon Cargo Transfer Operations: Today, Cristoforetti continued with Dragon cargo operations.  The crew has approximately 3 hours of SpaceX-6 cargo operations remaining.

Mobile Servicing System (MSS) Operations:  Robotics Flight Controllers walked the Space Station Remote Manipulator System (SSRMS) off of worksite 4 Mobile Remote Servicer (MRS) Base System Power and Data Grapple Fixture (PDGF) 1 to the Node2 PDGF. Once the walk off was complete, they commanded the SSRMS to grapple Dragon in preparation for Thursday’s unberth and release.   In conjunction with today’s operations, Flight Controllers also performed a checkout of Latching End Effector A (LEE-A), and performed commissioning on the SSRMS Gear Box Limping (GBL) feature.  The LEE-A checkout gathered additional data on latching currents since the LEE-A was lubricated on Extravehicular Activity (EVA) 30 in February.  The GBL feature produces greater arm compliance than passive limping, and is intended to reduce the required rigidization force to capture a fixed grapple fixture.  Later today the Robotics Ground Controllers will maneuver LEE-B to grapple the SpaceX-6 Dragon Flight Releasable Grapple Fixture (FRGF) ready for Dragon unberth and release on GMT 141 (21 May 15). They will also perform an initial checkout of GBL on LEE-B during this operation.

ISS Daily Summary Report – 05/20/15

Posted on May 20, 2015 at 5:10 pm by HQ.
 

Double Cold Bag (DCB) Packing:  Virts and Kelly packed the +4 degrees Celsius (°C) DCB with conditioned Ice Bricks and samples from Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI)-2 and -32°C DCBs with Ice Bricks and frozen samples from MELFI-3.  The +4°C DCB will be returning with Cell Shape and Expression, CASIS PCG-3, Nematode Muscles, and NanoRacks Module-53 samples.  The -32°C DCB will be returning with frozen HRP samples.  Once packed, the DCBs were placed in Dragon prior to hatch closure.

SpaceX-6 Departure Preparations:  This morning, the crew completed final cargo loading. Later, they configured Dragon’s pressurized segment for departure and closed its hatch.  Once the Dragon hatch was closed, they configured the Node 2 vestibule by removing Air Revitalization System (ARS) and data jumpers then installed the Common Berthing Mechanism (CBM) Controller Panel Assemblies (CPAs). SpaceX-6 unberth activities are scheduled to start this evening at 11:30pm CDT and Dragon release at ~6:04am CDT Thursday morning utilizing the Space Station Remote Manipulator System (SSRMS).

Node 3 Forward 2 Stowage Removal:  In preparation for Permanent Multipurpose Module (PMM) relocation next week, Virts removed stowage from the Node 3 Forward location. PMM relocation from Node 1 nadir to Node 3 forward is planned for Wednesday, May 27th.

ISS Daily Summary Report – 05/21/2015

Posted on May 21, 2015 at 5:50 pm by HQ.
 

SpaceX-6 Dragon Departure:  Overnight, the crew disconnected both power jumpers, installed the Center Disk Cover, and closed Node 2 Nadir Hatch.  They then successfully depressurized and pressure checked the Node 2/Dragon vestibule.  Dragon was unberthed from the Node 2 Nadir docking port and subsequently released by the crew utilizing the Space Station Remote Manipulator System (SSRMS) at 6:04am CDT this morning.  Dragon splashdown was in the Pacific Ocean landing zone at 11:42am CDT. The Recovery team has Dragon safely on the recovery boat and they are heading to port.

Fluids Integrated Rack (FIR) Advanced Colloids Experiment (ACE)-Microscopy-3 (M3):  Virts accessed the FIR Light Microscopy Module (LMM) and removed the Auxiliary Fluids Container (AFC) that housed the ACE-M3 sample.  He removed the sample and using the Binary Colloidal Alloy Test (BCAT)-3 magnet mixed the samples prior to returning the sample to the LMM.  ACE-M3 research involves the design and assembly of complex three-dimensional structures from small particles suspended within a fluid medium. These so-called self-assembled colloidal structures are vital to the design of advanced optical materials. In the microgravity environment, we will study the relation between particle shape, crystal symmetry and structure, a fundamental issue in condensed matter science.

BCAT-Low Gravity Phase Kinetics Platform (KP) Intervelometer Change:  Cristoforetti changed the camera battery, transferred images to a laptop for ground controllers to downlink, and then set the D2Xs intervalometer.  The BCAT-KP experiment aims to help materials scientists develop new consumer products with unique properties and longer shelf lives. Colloids are mixtures of small particles distributed throughout a liquid, which include milk, detergents and liquid crystals. Gravity affects how the particles clump together and sink, making the International Space Station an ideal platform to study their fundamental behaviors.

Columbus Solid State Drive Installation:  Kelly removed the two Columbus Video Cassette Recorders (VCR) from the starboard end cone then replaced them with two newer design Solid State Drive (SSD) recorders. The newer SSD recorders will provide additional recording capability without the use of Hi-8 tapes. During cable connection portion of the activity, the crew encountered issues with connector clearances. Ground teams are investigating the problem.

ISS Daily Summary Report – 05/22/15

Posted on May 22, 2015 at 5:50 pm by HQ.
 

Ocular Health (OH): Virts and Cristoforetti completed their Return (R)-30 OH today.  They each performed ultrasounds of their eye with the assistance of the other crewmember acting as a Crew Medical Officer (CMO).  Virts, again with Cristoforetti as his CMO, performed an ultrasound echocardiogram. The Ocular Health protocol calls for a systematic gathering of physiological data to characterize the risk of microgravity-induced visual impairment/intracranial pressure in ISS crewmembers. Researchers believe that the measurement of visual, vascular and central nervous system changes over the course of this experiment and during the subsequent post-flight recovery will assist in the development of countermeasures, clinical monitoring strategies, and clinical practice guidelines.

Biolab Microcassette Review: Cristoforetti removed the distribution and cleaning (D&C) cassette from the Biolab Microscope.  She then removed all syringes from the Biolab Automatic Ambient Stowage (AAS) Standard Insert and then installed it into the AAS compartment.  The Microcassette, containing data from the TripleLux-A experiment, will be returned on 41 Soyuz for ground specialists to analyze the data.  Triplelux-A uses a rat macrophage cell line to investigate and compare the ability of macrophages to kill pathogens under normal gravity and microgravity conditions.  The goal is to gain a better understanding of immune suppression in spaceflight.

Extravehicular Mobility Unit (EMU) Loop Scrub:  Kelly configured EMU Suits 3005 and 3010 for today’s loop scrubbing activity. He then initiated the ionic and particulate filtration (scrubbing) and conducted biocidal maintenance (iodination) on EMU 3005 and Airlock cooling water loops. An issue was detected with cooling on EMU 3010, therefore scrubbing was not performed on that suit.  Water samples were obtained after the loop scrub activity to determine the effectiveness of the filtering.  A portion of this water sample will used for a conductivity test and the remaining water will be sent to the ground for chemical analysis. Ground Teams are investigating the cooling issue with EMU 3010.

Mobile Servicing System (MSS) Operations:  Robotics Ground Controllers powered up the MSS and walked the Space Station Remote Manipulator (SSRMS) off Node 2 Power Data Grapple Fixture (PDGF) onto the Lab PDGF. After completing the walk off, the Robotics Ground Controllers maneuvered the SSRMS to Node3 Forward survey start position and reconfigured both arms of Special Purpose Dexterous Manipulator (SPDM) in preparation of Permanent Multipurpose Module (PMM) relocation next Wednesday. MSS performance today was nominal.

Wastewater Storage Tank Assembly (WSTA) Slow Fill Troubleshooting – Over the past few weeks, it has taken significantly longer than expected to transfer pretreated urine from an EDV to the WSTA.  Today the crew performed troubleshooting steps to attempt to correct the issue.  They first transferred pretreated urine using the Russian compressor to determine if the pressure supply is the cause of the slow transfer.  This had no effect on the transfer rate.  They then back-flowed pretreated urine from the WSTA into an EDV to attempt to clear any air bubbles or blockage that could be restricting flow through the filter of the EDV transfer hose.  A subsequent WSTA fill initially showed improvement for the first 5-10% of the fill but then returned to the prior slow fill rate.  Ground teams will continue to troubleshoot the issues.

International Docking Adapter (IDA)1 Control Panel Checkout:  Virts performed a checkout of the IDA1 Control Panel.  The IDA1 Control panel was installed earlier in the increment and will be used during the IDA1 install EVA, currently planned later this year.

ISS Daily Summary Report – 05/25/2015

Posted on May 25, 2015 at 10:25 am by HQ.
 

Fluid Shifts Before, During and After Prolonged Space Flight and Their Association with Intracranial Pressure and Visual Impairment (Fluid Shifts):  Kelly and Padalka performed a system test of the Ultrasound in the Service Module.  The crew configured the ultrasound, laptop, and video, and with assistance from the ground remote guider, then performed an ultrasound scan.  This test of capability is to verify capability in advance of the Fluid Shift ultrasound operations when the crew uses the Lower Body Negative Pressure (Chibis) suit next week.  This week, the crew will be performing their baseline data collections in the United States On-orbit Segment (USOS).  Fluid Shifts is a joint NASA-Russian experiment that 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 investigated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and eye damage.

Marangoni Deformation 30 (Dynamic Surf-3):  Cristoforetti set up the Fluid Physics Experiment Facility (FPEF) Dynamic Surf-3 core and body.  She then configured the Dynamic Surf-3 cassette, installed it into the core and body.  The assembly was then installed into the FPEF.  Cristoforetti completed the Dynamic Surf-3 setup activities on Wednesday, with the ground checkout activities later that night. The Dynamic Surf investigation is part of a series of JAXA experiments that Marangoni convection driven by the presence of surface tension gradient as produced by a temperature difference at a liquid/gas interface. Fluid convection observations of a silicone oil liquid bridge that is generated by heating the one disc higher than the other within the Fluid Physics Experiment Facility (FPEF). By observing and understanding how such fluids move researchers can learn about how heat is transferred in microgravity, and ultimately drive the design and development of more efficient fluid flow based systems and devices.  The objective of scientific research on Marangoni convection utilizing microgravity is to make clear the flow transition phenomena from steady to oscillatory, chaotic, and finally turbulent flows. Therefore, it is important to understand an underlying principal of Marangoni convection. The findings and knowledge obtained through the space experiment is applied to industrial processes, as well as fluid physics.

Handhold Experiment Platform (HXP) Installation: This week the crew and ground controllers will be installing the HXP on the JEM Exposed Facility (JEF).  Today, ground controllers used the JEM Remote Manipulator System (JEMRMS) to retrieve the Small Fine Arm (SFA).  On Tuesday, the JEM Airlock (JEMAL) outer hatch will be opened and slide table extended for the SFA to grapple the HXP and install on one of the handrails of the JEF.  The HXP is composed of several exposure experiments which will remain attached to the JEF for approximately one year, collecting data on material interactions to long duration space exposure.

Extravehicular Mobility Unit (EMU) Loop Scrub:  Virts configured EMU suits 3003 and 3010 for today’s activities.  He then successfully initiated ionic and particulate filtration (scrubbing) on both suits.  Later during biocidal maintenance (iodination), EMU 3010 was unable to establish sufficient cooling water flow to complete the process.  Iodination maintenance was successfully performed on EMU 3003.  A water sample was obtained to determine the effectiveness of the filtering. A portion of this water sample will used for a conductivity test and the remaining water will be sent to the ground for chemical analysis. Ground Teams are currently planning to perform a Fan Pump Separator change out on EMU 3010 during the first week of June.

Permanent Multipurpose Module (PMM) Preparation:  In preparation for the upcoming PMM relocation, Kelly has secured PMM Rack hardware and stowage.  In addition, he gathered vestibule outfitting hardware for Node 1 Nadir and Node 3 Forward ports later in the day.  PMM relocation from Node 1 Nadir to Node 3 Forward is planned for Wednesday, May 27th starting at 4:30am CDT.

ISS Daily Summary Report – 05/26/2015

Posted on May 26, 2015 at 3:48 pm by HQ.
 

Fine Motor Skills (FMS): Kelly and Kornienko performed their Flight Day 60 FMS sessions this morning.  In the Fine Motor Skills experiment, crew members perform a series of interactive tasks on a touchscreen tablet. Fine motor skills are crucial for successfully interacting with touch-based technologies, repairing sensitive equipment, and a variety of other tasks. In Fine Motor Skills, crew members perform a series of interactive tasks on a touchscreen tablet. The investigation is the first fine motor skills study to measure long-term microgravity exposure, different phases of microgravity adaptation, and sensorimotor recovery after returning to Earth gravity.

Handhold Experiment Platform (HXP) Installation: Today, the JEM Airlock outer hatch was opened and slide table extended for the Small Fine Arm (SFA) to grapple the HXP and install on one of the handrails of the JEM Exposed Facility (JEF).  The HXP is composed of several exposure experiments which will remain attached to the JEF for approximately one year, collecting data on material interactions to long duration space exposure.

Permanent Multipurpose Module (PMM) Relocation Preparation:  In support of tomorrow’s PMM relocation, the crew installed the Centerline Berthing Camera System (CBCS) on Node 3 Forward hatch this morning.  Later, they configured PMM for egress by deactivating lights, closed Node 1 Remotely Actuated Motorized Valve (RAMV), removed Inter-module Ventilation (IMV) and remaining power and data jumpers, then closed the PMM hatch.  Once the PMM hatch was closed, the crew performed Node 1 Nadir CBM Control Panel Assembly (CPA) installation, connected Node 1 bulkhead feedthrough power cable, installed the Center Disk Cover, closed Node 1 Nadir Hatch, and depressurized the vestibule. PMM relocation from Node 1 Nadir to Node 3 Forward is planned for tomorrow morning starting at approximately 4:30 am CDT.
