ISS Daily Summary Report – 11/15/2017
 

Probiotics Operations: The crew completed the second half of the second sampling phase that began on GMT 316 with fecal sample collections. Today’s activities included saliva sample collections, a questionnaire, and a capsule intake. This sampling phase was the second of four sampling phases for the JAXA Probiotic experiment. Some species of harmful bacteria such as Salmonella grow stronger and more virulent in the microgravity environment of space. At the same time, the human immune system is weaker in space, leading to increased health risks. The objective of the Probiotics investigation is to study the impact of continuous consumption of probiotics on immune function and intestinal microbiota in astronauts under closed microgravity environment This investigation studies the effects of beneficial bacteria (Probiotics) to improve crew members’ intestinal microbiota as well as their immune function on long-duration space missions.

TangoLab-2 Card Cube Placement: The crew removed two CubeLabs from a polar that arrived on Orbital 8 (OA-8) and placed the cards in slots 5 and 7 of the TangoLab-2.  TangoLab provides a standardized platform and open architecture for experimental modules called CubeLabs. CubeLab modules may be developed for use in 3-dimensional tissue and cell cultures.

Microgravity Experiment Research Locker / INcubator (MERLIN) Sample Transfer: The crew transferred science samples from the powered MERLIN in OA-8 to the STaARS-1 Experiment Facility on the ISS. The objective of the Space Technology and Advanced Research Systems, Inc.-1 Experiment Facility (STaARS-1 EF) is to support biotechnology and life science investigations to characterize the effects of microgravity on living systems. The STaARS-1 EF aims to facilitate advanced studies targeting the molecular responses to microgravity that alter cell physiology and lead to unique cellular processes and the production of novel compounds that can impact pharmaceutical, tissue engineering, regenerative medicine, biofuel, and discovery sciences.

Robotics Operations:  Overnight, ground controllers ungrappled the Space Station Remote Manipulator System (SSRMS) from the Cygnus module and maneuvered it to pick up the Special Purpose Dexterous Manipulator (SPDM).  Today, the SSRMS/SPDM system will be used to move the UTA from ESP2 to ELC-1, and moved the LEE from its place on ELC-1 to ESP2.

Cygnus Status: Following yesterday’s successful berthing and crew ingress, today the crew began cargo transfer operations:

On-Board Training (OBT) Cygnus: With the arrival and ingress of OA-8 yesterday, the crew performed an emergency procedures review. All crew members participated in this mandatory OBT.

The crew mentioned to Houston that they observed, and were able to photograph, a sizable re-entry last night.  Paolo has apparently witnessed similar events previously and the crew noted the re-entry was on several frames of imagery and that the ground was illuminated prior to presumed impact.  Houston noted that they were "perusing" the internet for possible correlating events after noting the crew note on the incident this morning.

Any further news?  When/where?  Any independent sightings from land, sea, or air?

I think it's at about 10 seconds in the video

http://blogs.esa.int/VITAmission/2017/11/16/the-backstory-paolo-spots-a-meteoroid-from-the-iss/

The backstory: Paolo spots a meteoroid from the ISS   

Earlier today, we posted a remarkable video comprising a series of night-time photos captured by Paolo Nespoli on 5 November around 22:33 GMT. The images are shown in a time-lapse with a 1-second interval, and were taken while the Space Station was flying from the southern Atlantic Ocean over to Kazakhstan.

Paolo was lucky enough to capture a fast fireball falling to Earth over the Atlantic, off the South Africa west coast – look closely in the video below between 00:07 and 00:08 seconds (at upper right in the frame).

To understand in more detail what Paolo saw, we asked ESA’s Rüdiger Jehn and Detlef Koschny, responsible for near-Earth object (NEO ) activities at the Agency’s Space Situational Awareness Programme, to examine the images.

Comments from Detlef Koschny

    Indeed it looks like a bright meteor, or fireball. When I stretch the scale then I can see that the object was below the airglow – assuming it was close to the Earth limb – see the brightness-adjusted screenshot below:

    In the later images, one can see the fireball illuminating the clouds from above, so it must have been close to them – and close to the Earth’s limb. It also seems to show a little tail.
    It’s brighter than all the stars seen in the background; only at the very end of the video before sunrise do we see something of similar brightness – I guess Venus. So, if it is a meteor then it could be a decimeter-sized object.
    It might be a re-entering piece of space debris, but from looking at the entry angle (using the reflection on the clouds as reference) it’s coming in at too steep an angle.

Comments from Rüdiger Jehn

A fireball is basically a very bright meteoroid – a small bit of natural “space rock” – entering Earth’s atmosphere and burning brighter than the background stars. This particular meteoroid was moving much faster than typical, with an estimated speed of around 40 km/s.

This speed is actually quite fast for meteoroids, which typically enter the atmosphere at around 20 km/s.

To get this estimate, Rüdiger went through a rather intricate process, which he explains below:

    I overlaid Paolo’s images with a grid, and measured the distance that the meteoroid was moving between image 2 and 5 (see the faint red line in the image below).

    I then assumed that the meteoroid was moving without radial velocity in the plane which is at the horizon and crossed the ‘centre’ of the Earth.
    With this, I measured a distance of 97 km and assuming that image 2 and 5 in the movie are 3 seconds apart, then the velocity would be 32 km/s.
    Adding a small radial velocity component might bring the velocity maybe to 40 km/s, which is quite a fast meteoroid (they average around 20 km/s) – but still in the observable range between 11 and 72 km/s.

Detlef added:

As for the naming convention: A meteor is the light you see when a meteoroid or asteroid enters the atmosphere. The object that causes it – the little piece of rock – is called ‘meteoroid’ if smaller than 1 m, ‘asteroid’ if larger than 1 m (unlikely for this one).

We call bright meteors (brighter than Venus), a fireball. I guess this would qualify as a fireball.

Best quote heard during an inspection, "I was unaware that I was the only one who was aware."

BEAM Prepped for Cargo, CubeSats Deployed and Leg Muscles Scanned

An experimental module attached to the International Space Station is being prepared for upcoming cargo operations. Tiny research satellites were also ejected from the orbital lab while a pair of Expedition 53 crew members scanned their leg muscles today.

BEAM, officially called the Bigelow Expandable Activity Module, is being outfitted this week for future stowage operations. Excess gear, including inflation tanks and dynamic sensors, used during its initial expansion back in May of 2016 is being removed to make room for new cargo. BEAM’s old gear and trash will now be stowed in the Cygnus resupply craft for disposal early next month.

The Kibo lab module from the Japan Aerospace Exploration Agency was the site for the deployment of several CubeSats Monday morning. A mechanism attached to the outside of Kibo ejected the CubeSats that will orbit Earth and provide insights into antibiotic resistance, astrophysics and “space weather.” More CubeSats will be deployed Tuesday.

Flight Engineers Paolo Nespoli and Sergey Ryazanskiy spent Monday exploring how the lack of gravity affects leg muscles. Nespoli strapped himself into a specialized exercise chair and attached electrodes to his leg with assistance from Ryazanskiy. The Sarcolab-3 experiment uses measurements from an ultrasound device and magnetic resonance imaging to observe impacts to the muscles and tendons of a crew member.

ISS Daily Summary Report – 11/16/2017
 

Marrow: Upon wakeup, a 52S crewmember conducted breath and ambient air sample collections for the Marrow investigation, which looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.

NanoRacks-DreamUp Xtronaut Microbe (DreamXM) Operations: To initiate the NanoRacks DreamXM experiment, today a crewmember used cotton swabs to sample locations and inoculate several Petri Dishes to begin the DreamXM experiment.  Photos were taken of each Petri Dish as a baseline data point. Kits containing nearly identical materials were provided to students to perform a duplicate ground experiment. NanoRacks(DreamXM) teaches students the different microbial growths from a home-school setting and those in microgravity using near-identical flight kits flown and operated in the International Space Station (ISS). With access to an online portal, students swab away, paralleling the procedures of crew members and comparing results with online videos and datasets. The investigation aims to promote science, technology, engineering and math (STEM) fields to the next generation of students.

At Home in Space:  The crew took photographs to document ISS culture. This Canadian Space Agency investigation assesses culture, values, and psychosocial adaptation of astronauts to a space environment shared by multinational crews on long-duration missions. It is hypothesized that astronauts develop a shared space culture that is an adaptive strategy for handling cultural differences and they deal with the isolated confined environment of the spacecraft by creating a home in space. At Home in Space also uses questionnaires to investigate individual and culturally related differences, family functioning, values, coping with stress, and post-experience growth.

Fluids Integrated Rack (FIR) Light Microscopy Module (LMM) Camera Data Cable Swap: Today the crew exchanged data connections from the LMM Wide-field Camera to the LMM Confocal Camera and then relocated the connection of Fluids and Combustion Facility (FCF) Image Processor cable to troubleshoot the LMM wide-field camera data cable and connectors. The results of today’s troubleshooting activities are currently being assessed by the ground teams to determine if the Wide-field data cable should be replaced.  The Light Microscopy Module (LMM) is a modified commercial, highly flexible, state-of-the-art light imaging microscope facility that provides researchers with powerful diagnostic hardware and software onboard the International Space Station (ISS). The LMM Wide field camera will be used for every payload in the FIR.

Earth Imagery from ISS Target Operations: The crew captured images of Seattle and the Northwest Pacific, fishing boats in the Gulf of Thailand, and the Nile Delta at night. The Earth Imagery from ISS investigation creates a series of videos, showcasing Earth from space. These videos will be taken with cameras on the International Space Station in 6K hi-resolution, then integrated into videos for screensavers for public enjoyment, exploration, and engagement.

Two Phase Flow Operations:  The crew conducted checkout activities for the Two Phase Flow experiment equipment. The Two Phase Flow investigation seeks to build a database on the heat transfer efficiency of liquids in space that can be used in the design of high-performance thermal management systems for future space platforms.

Waste and Hygiene Compartment (WHC) Urine Hydraulic Components Remove & Replace (R&R): The crew performed preventive maintenance to R&R the urine valve block, urine lines, urine pressure sensors and WHC flush water tank empty pressure sensor.

Port Thermal Radiator Rotary Joint (TRRJ) Imagery:  The crew took imagery of the Port TRRJ from the Docking Compartment 1 (DC1) Window. During this task, the port radiator was rotated to specific angles in order to photograph specific sections of the radiator.

Space Station Computer (SSC) Server Deploy:  Today the crew deployed and configured a ZBook Laptop to be used as a Server to replace the T61p Linux Server 1 (LS1) Laptop.

ISS Server1 Rebuild:  Tonight during crew sleep, ground controllers will deploy a new build of the ISS Server1 Virtual Machine (VM).  In recent weeks, ISS Server1 has experienced numerous spontaneous lockups, causing disruptions to operations onboard.  The new build of Server1 has some modifications to it which are hoped to resolve the lockup issue.

On Board Training (OBT) Cygnus Rendezvous Debrief: Today the USOS crew participated in a debrief with ground teams to cover questions and comments related to Cygnus capture and berthing.

Spare Latching End Effector (LEE)/Utility Transfer Assembly (UTA) Flight Releasable Attachment Mechanism (FRAM) Swap:  This morning, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and Special Purpose Dexterous Manipulator (SPDM) to remove the UTA from External Stowage Platform (ESP)-2 and translated the Mobile Transporter (MT) from Work Site (WS)-4 to WS-7. They then removed the LEE and installed the UTA on ELC-1. Today, the MT was translated back to WS-4 from WS-7.  Later this evening, the LEE will be installed on ESP-2. These activities are in preparation for EVAs planned next January.

ISS Daily Summary Report – 11/17/2017
 

NanoRack Cubesat Deployer (NRCSD) #13: Installation: This morning, the JEM A/L inner hatch was opened and the slide table was extended to the JPM side. The crew then installed the NRCSD #13 deployer onto the Multipurpose Experiment Platform (MPEP). The slide table was retracted from the JPM side and the inner hatch was closed.  The Airlock was then depressurized in preparation for the planned deployment of the CubeSats next week.

Sarcolab-3:  Today the crew set up and configured the Muscle Atrophy Research & Exercise System (MARES) facility in the Columbus module for Sarcolab-3 operations next week.  They installed the Ankle configuration and Electromyograph and Percutaneous Electrical Stimulation (PEMS) devices on MARES.  The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss.  Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus, or calf muscle, where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crewmembers before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

Human Research Program (HRP) Collections (Biochemical Profile, Marrow, and Repository): A 51S crewmember completed Flight Day (FD) 60 blood sample collections to support the Biochemical Profile and Repository experiments. The samples were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).
•The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body.
•Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.
•Marrow looks at the effect of microgravity on bone marrow. It is believed that microgravity, like long-duration bed rest on Earth, has a negative effect on the bone marrow and the blood cells that are produced in the bone marrow.

Earth Imagery from ISS Target Operations: The crew captured video footage of the Indian-Himalayas-Tibetan Plateau, Seattle, and the Northwest Pacific. The Earth Imagery from ISS investigation creates a series of videos, showcasing Earth from space. These videos will be taken with cameras on the International Space Station in 6K hi-resolution, then integrated into videos for screensavers for public enjoyment, exploration, and engagement.

Story Time from Space: A crewmember participated in the Story Time from Space project by reading “Notable Notebooks Scientists and Their Writing” today while being videotaped.  The recording will be downlinked and used for educational purposes. Story Time rom Space combines science literacy outreach with simple demonstrations recorded aboard the ISS. Crewmembers read science, technology, engineering and mathematics-related children’s books on orbit, and complete simple science concept experiments. Video and data collected during the demonstrations are downlinked to the ground and posted in a video library with accompanying educational materials.

Space Headaches:  The crew completed the weekly questionnaire for the ESA Space Headaches investigation. The Space Headaches investigation collects information that may help in the development of methods to alleviate associated symptoms and improvement in the well-being and performance of crewmembers in space. Headaches during space flight can negatively affect mental and physical capacities of crewmembers that can influence performance during a space mission.

Spare Latching End Effector (LEE)/Utility Transfer Assembly (UTA) Flight Releasable Attachment Mechanism (FRAM) Swap:  Overnight, the MT translated back to WS-7 from WS-4 and the spare LEE was installed on ESP-2. These activities are in preparation for EVAs planned next January, and have positioned the spare LEE in a more EVA-accessible location for the LEE R&R.

Pressure Probe Troubleshooting:  Today, the crew performed troubleshooting on the Internal Sampling Adapter Scopemeter Pressure Probe and multimeter.  This hardware exhibited issues earlier this week while performing JEM ITCS maintenance.

ISS Server1 Rebuild:  Thursday evening during crew sleep, ground controllers deployed a new build of the ISS Server1 Virtual Machine (VM).  In recent weeks, ISS Server1 has experienced numerous spontaneous lockups, causing disruptions to operations onboard.  The new build of Server1 has some modifications to it which are hoped to resolve the lockup issue.

ISS Daily Summary Report – 11/20/2017
 

NanoRack CubeSat Deployer (NRCSD) #13 Deploy: Today three NRCSD #13 deployers were individually ground commanded by JAXA to deploy from the International Space Station (ISS). Due to the configuration of single- and double-wide deployers, NRCSD #13 has a total five deployers (silos 1, 3, 5, 7, and 8).  There are no deployers for silos 2, 4, and 6. Today, the crew recorded video still photos of the satellite deployment.    Deployer silos #3 (EcAMSAT) and #1 (ASTERIA) were nominally deployed.  The third double-wide deployer, silo #5 (RBLE), did not initially deploy upon command.  After several attempts and some troubleshooting, the RBLE satellite was deployed.  Each of the three silos deployed today contained a single 6U CubeSat.  Deployers #7 (TechEdSat) and #8 (OSIRIS-3U) will be deployed tomorrow.

Earth Imagery from ISS Target Operations: Over the weekend the crew captured images and video footage of the South Tip of India, the Indian-Himalayas-Tibetan Plateau, the Hawaiian Islands, the Mediterranean Sea at Night, and Seattle and the Pacific Northwest US. The Earth Imagery from ISS investigation creates a series of videos, showcasing Earth from space. These videos were taken with cameras on the International Space Station in 6K hi-resolution, then will be integrated into videos for screensavers for public enjoyment, exploration, and engagement.

Human Research Program (HRP) Collections (Biochemical Profile and Repository): Over the weekend, 52S crewmembers completed Flight Day (FD) 60 urine sample collections, and today blood and urine samples were collected to support the Biochemical Profile and Repository experiments. Once collected, samples were placed in the Minus Eighty Degree Celsius Laboratory Freezer for ISS (MELFI).
•The Biochemical Profile experiment tests blood and urine samples obtained from astronauts before, during, and after spaceflight. Specific proteins and chemicals in the samples are used as biomarkers, or indicators of health. Post-flight analysis yields a database of samples and test results, which scientists can use to study the effects of spaceflight on the body.
•Repository is a storage bank used to maintain biological specimens over extended periods of time and under well-controlled conditions. This repository supports scientific discovery that contributes to our fundamental knowledge in the area of human physiological changes and adaptation to a microgravity environment and provides unique opportunities to study longitudinal changes in human physiology spanning many missions.

Sarcolab-3:  A USOS crewmember with Russian operator assistance ingressed into the Muscle Atrophy Research & Exercise System (MARES) chair and adjusted the pads and restraints to complete the Sarcolab-3 ankle protocol.  The operator collected ultrasound images of the subject’s leg. The data collected for Sarcolab-3 will be compared to pre and post flight measurements to assess the impact of hypothesized microgravity induced muscle loss.  Myotendinous and Neuromuscular Adaptation to Long-term Spaceflight (Sarcolab) investigates the adaptation and deterioration of the soleus (calf muscle) where it joins the Achilles tendon, which links it to the heel and carries loads from the entire body. Muscle fiber samples are taken from crewmembers before and after flight, and analyzed for changes in structural and chemical properties. MRI and ultrasound tests and electrode stimulation are conducted to help assess muscle and tendon changes caused by microgravity exposure.

NanoRacks Vuze (One Strange Rock) Camera Mounted Operations: The crew deployed the NanoRack Vuze camera to record 3-dementional 360-degree videos inside of the ISS. The mounted camera captured a “day in the life” style footage as the crew went about their nominal tasks throughout the ISS. National Geographic Channel–Virtual Reality Educational Video for Television Series–“One Strange Rock” (One Strange Rock Virtual Reality) is a 10-part series that transports a virtual reality camera to the ISS for recording of a National Geographic special on the Earth as a natural life-support system. Crew aboard the ISS record a series of virtual reality pieces for incorporation into a larger documentary about natural history and the solar system. Each episode features a different crewmember and addresses different topics using next generation virtual reality technology to raise awareness about the Earth system and the space program.

Meteor Grating Configuration and Hard Drive Exchange: The crew removed and replaced diffraction gratings in the Meteor camera and then removed and replaced the hard drive in the Meteor laptop located in the Window Observational Research Facility (WORF) payload volume. The Meteor payload is a visible spectroscopy instrument with the primary purpose of observing meteors in Earth orbit. Meteor uses image analysis to provide information on the physical and chemical properties of the meteoroid dust, such as size, density, and chemical composition. Since the parent comets or asteroids for most of the meteor showers are identified, the study of the meteoroid dust on orbit provides information about the parent comets and asteroids. 

Bigelow Expandable Aerospace Module (BEAM) Outfitting:  This week, the crew is outfitting BEAM to make room for future stowage capability inside BEAM.  Today, the crew removed hardware from BEAM and disposed most of it on OA-8 Cygnus. The crew removed a stowage locker, wire harness cover, wire harness and Rip Stitch Straps.  They crew then removed the Deployment Dynamic Sensor system that was used for inflation of BEAM, which will be returned on a future flight.  Finally, the crew removed the empty inflation tanks.  The crew will continue with the outfitting activities tomorrow.

Cygnus Cargo Operations:  The ISS crew completed 2 hours and 30 minutes of OA-8 cargo operations today. At this time an estimated 78% of OA-8 cargo operations have been completed, leaving approximately 10 hours remaining. Ground teams continue to gather request to dispose of items on the Cygnus vehicle, which may increase the amount of time required to completed the loading operations.

New York Students to Speak with NASA Astronauts on Space Station


Students at U.S. Military Academy in West Point, New York, will speak with NASA astronauts living, working and doing research aboard the International Space Station at 9:15 a.m. EST Monday, Nov. 27. The 20-minute, Earth-to-space call will air live on NASA Television and the agency’s website.

Randy Bresnik, Mark Vande Hei and Joe Acaba will be asked questions by students. The discussion will include topics about life aboard the space station, NASA’s deep space exploration plans, and scientific research in space.             

This is Bresnik’s second mission to the station, and he serves as the station’s Expedition 53 commander. Bresnik launched to the orbiting laboratory on July 28 and is scheduled to return to Earth in December. Vande Hei and Acaba both arrived at the space station on Sept. 12. This is Vande Hei’s first space mission and Acaba’s third. Both will return to Earth in February 2018.

Vande Hei was an assistant professor of physics at West Point. He and his crewmates will speak to cadets in the Department of Physics and Nuclear Engineering. West Point was selected through a competitive process to host a downlink with the station.

Media interested in attending the event should contact Kimberly Lewis at [email protected] or 845-938-7907. United States Military Academy is at 900 Washington Road in West Point.

Linking students directly to astronauts aboard the space station provides unique, authentic experiences designed to enhance student learning, performance and interest in science, technology, engineering and math (STEM). This in-flight education downlink is an integral component of NASA’s Year of Education on Station which provides extensive space station-related resources and opportunities to students and educators.
