ISS Daily Summary Report - 9/05/2019

60 Soyuz (60S) Undock/Landing Preparation:

 :

The 60S unmanned vehicle has been activated in preparation for tomorrow's undocking at 1:14 PM CT and landing in Kazakhstan at 4:34 PM CT. The hatches between the Soyuz and ISS have been closed and successful leak checks performed. No US cargo is manifested for return on this unmanned flight. Therefore, no NASA personnel will be at the landing site.

Fluid Shifts:

 :

The crew performed several activities including Cerebral and Cochlear Fluid Pressure (CCFP), Distortion Product Otoacoustic Emission (DPOAE) measurements, Optical Coherence Tomography (OCT), and ultrasound scans in support of the Fluid Shifts investigation. This is week 2 of the 3 week sequence and focuses on baseline imaging. Fluid Shifts is a NASA investigation, divided into Dilution Measurements, Baseline Imaging, and Imaging with Chibis and is typically spread over several weeks. The Chibis hardware is used to perform the Lower Body Negative Pressure (LBNP) part of the experiment. 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 LBNP device is being evaluated as a possible intervention. Results from this study may help to develop preventative measures against lasting changes in vision and prevention of eye damage.

Fluid Science Laboratory/Reference mUltiscale Boiling Investigation (FSL/RUBI) Cable Exchange:

 :

As a corrective measure for a power cable with bend radius issues, the crew replaced the short power cable with a power cable previously used successfully for the Soft Matter Dynamics experiment. Nucleate boiling is a process that is used in many technical applications of heat transfer. Examples are power plants and reactor technology, air conditioning technology as well as chemical and process engineering. The design of new processes and evaporators is significantly hindered by the fact that general methods of calculation are not available yet. The development of such methods requires a better understanding of highly complex and dynamic transport phenomena.

Microgravity Crystals:

 :

In support of day 6 of the on-going experiment run, the crew set up a microscope, then took images of the solutions and any crystals in the wells of the crystal plates. The Microgravity Crystals investigation crystallizes a membrane protein that is integral to tumor growth and cancer survival. Although crystallization of this protein has yielded unsatisfactory results on Earth, this investigation leverages extensive protein crystallization work on the space station, significantly increasing the likelihood of successful crystal growth. Results may support development of cancer treatments that target the protein more effectively and with fewer side effects.

Rodent Research-17 (RR-17) Maintenance:

 :

The crew restocked Habitats 2 and 3 and cleaned the access unit. RR-17 uses younger and older mice as model organisms to evaluate the physiological, cellular and molecular effects of the spaceflight environment. Some responses to spaceflight in humans and model organisms such as mice resemble accelerated aging. This investigation provides a better understanding of aging-related immune, bone, and muscle disease processes, which may lead to new therapies for use in space and on Earth.

Space Moss:

 :

The crew detached the plant experiment unit from the Cell Biology Experiment Facility (CBEF) micro-G incubator unit and set up the Space Moss Sample on the Microscope for observation. Space Moss grows mosses aboard the ISS and on Earth to determine how microgravity affects their growth, development, gene expression, photosynthetic activity, and other features. Tiny plants without roots, mosses need only a small area for growth, an advantage for their potential use in space and future bases on the Moon or Mars.

Time Perception:

 :

Using a head-mounted Oculus Rift display/headphones, a finger trackball, and support computer, several crewmembers performed the Time Perception experiment sessions. Although some initial issues were encountered, they were resolved by using a backup headset. In this experiment, a program on the laptop induces visual and audio stimuli to measure a subject's response to spatial and time perception in a microgravity environment. The accurate perception of objects in the environment is a prerequisite for spatial orientation and reliable performance of motor tasks. Time is fundamental to motion perception, sound localization, speech, and fine motor coordination.

Main Bus Switching Unit (MBSU) Operations:

 :

To finalize this week's MBSU operations, today the failed MBSU was removed from the Japanese Experiment Module Airlock (JEMAL) slide table and placed in a Cargo Transfer Bag (CTB). The MBSU-3 was declared hard failed on April 29, 2019. The MBSU will return to ground on SpaceX-19.

Extravehicular Activity (EVA) Systems Briefing Package Review:

 :

In preparation for the planned P6 Battery EVAs, the crew reviewed the Intravehicular (IV) briefing package which provides reminders, emergency briefing, helpful tips and procedures used during EVA preparation.

JAXA Spacecraft Carries Science, Technology to the Space Station


The Japanese Space Agency (JAXA) developed an uncrewed cargo transfer craft, called the H-II Transfer Vehicle (HTV), to deliver supplies to the International Space Station. This image shows the HTV-7 resupply ship after its release from the Canadarm2 robotic arm as the space station orbited above the Pacific Ocean some 311 miles west of Baja California.

The Japan Aerospace Exploration Agency (JAXA) cargo ship H-II Transfer Vehicle-8 (HTV-8) is scheduled to lift off Sept. 10 at 5:33 p.m. EDT (6:33 a.m. Japan Standard Time) to the International Space Station from Japan's Tanegashima Space Center, 10 years after JAXA launched its first HTV mission. HTV-8 arrives at the space station on Sept. 14.

Here are details about some of the scientific investigations and facilities heading to the orbiting lab on HTV-8.

Preparing for dusty landings

The new Hourglass investigation examines how different levels of gravity affect the behavior of granular materials such as regolith, dust that covers the surface of planets and planetary-like bodies. A better understanding of the behavior of these granular materials supports design of spacecraft for future landings on the Moon, Mars and other celestial bodies.


Samples for the Hourglass investigation include lunar, Mars and Phobos regolith simulants, Alumina beads, and Toyoura and Slica sands.

Scientists are conducting similar research on regolith and granular materials using the space station's Hermes research facility. Hermes provides long duration exposure to microgravity and the vacuum of space.

Better space-to-ground and space-to-space communication

The Demonstration of Small Optical Communication System (SOLISS) investigation demonstrates new technology for future broadband data communication in space. SOLISS is an optical system mounted on the Japanese Experiment Module (JEM), an external platform providing continuous exposure to space for a variety of experiments. SOLISS technology allows transmission of large amounts of data from the space station, as well as from satellites in geostationary orbit to ground stations.

Predicting flammability in microgravity

FLARE explores the flammability of materials in microgravity by burning various solid fuels under different conditions inside a flow tunnel. Microgravity significantly affects how combustion occurs, but current tests of the flammability of materials for crewed space missions do not consider the effect of gravity. This investigation demonstrates a new way to predict flammability in microgravity that could fill this gap and significantly improve fire safety aboard spacecraft on future exploration missions. Final components of the FLARE module arrive on the cargo ship.

The unpiloted Soyuz MS-14 spacecraft approaches the International Space Station for an automated docking.

Beginning at 1:45 p.m. EDT Friday, NASA Television and the agency's website will air the undocking and departure from the International Space Station of an uncrewed Russian Soyuz spacecraft. The Soyuz MS-14  is scheduled to undock from the station's aft-facing Zvezda module at 2:14 p.m.

The uncrewed Soyuz launched from the Baikonur Cosmodrome in Kazakhstan on Wednesday, Aug. 21 on a test flight to validate the spacecraft's compatibility with a Soyuz 2.1a booster rocket. The spacecraft arrived and docked to the station on Monday Aug. 26. The upgraded Soyuz spacecraft and the Soyuz booster will be used to transport crews to the International Space Station beginning in spring 2020.
