Crew Sets Up Advanced Science Gear, Loads Cargo Ship With Trash

The Expedition 63 crew started the workweek checking out hardware supporting life science, combustion research and ongoing Earth observations. A Russian cargo craft docked to the International Space Station is also being packed with old gear for disposal toward the end of the year.

The multitude of microgravity research that takes place every day on the orbiting lab, requires regular maintenance and monitoring by the crew or scientists on the ground. The ongoing research supports innovative applications and insights benefitting Earth and space industries.

Today, Commander Chris Cassidy serviced an advanced space microscope and swapped components supporting safe combustion investigations. Cassidy first configured the Light Microscopy Module, part of the Fluids Integrated Rack, which supports basic physics and biology research. Next, the veteran NASA astronaut replaced a burner and igniter tip inside the Combustion Integrated Rack that supports fuel and flame research.

On the Russian side of the space station, two cosmonauts focused on their slate of space research and lab maintenance.

Veteran Roscosmos Flight Engineer Anatoly Ivanishin tested battery temperatures and connections then took a 90-minute fitness test on the Zvezda service module’s treadmill. During the afternoon, Ivanishin changed out dust filters before activating hardware that measures the Earth’s nighttime atmosphere in near-ultraviolet wavelengths.

Cosmonaut Ivan Vagner, five weeks away from ending his first long-term space mission, joined Ivanishin for the morning battery inspections. Afterward, the first-time space flyer packed Russia’s Progress 75 cargo craft, docked to Zvezda’s rear port, with old and discarded station gear for disposal at the beginning of December.

Research into Fluid Dynamics, Astronaut Health and Earth Wraps Up Science-Centered Week

Aboard the International Space Station, a flurry of research activity is underway before the Expedition 63 crew winds down to the weekend, along with essential maintenance tasks to ensure the longevity of the orbiting laboratory.

Commander Chris Cassidy crossed off a few housekeeping items, like replacing the carbon dioxide sensor for the Cell Biology Experiment Facility and stowing Rodent Research hardware for return on a future SpaceX mission, in addition to completing additional tests runs and closeout activities in support of the Fluidics experiment. Future spacecraft and their fuel systems will get a boost from this investigation, which uses the measurement of liquid displacement within a sphere to gather observations in how fluids behave inside a fuel tank.

Cassidy also spent time working with the Advanced Plant Habitat mounted in the station’s EXPRESS rack to gather sound-level measurements. The habitat itself provides a large and enclosed chamber with stringent environmental controls, designed to give commercial and other bioscience research suitable conditions in which to grow despite the hostile environment to the station’s exterior: space.

Flight Engineers Anatoly Ivanishin and Ivan Vagner, cosmonauts from the Russian space agency Roscosmos, worked together to complete life-support hardware maintenance tasks such as inspecting and inventorying the gear. Ivanishin continued the routine chores, cleaning out the ventilation system within the Zvezda service module and also doing a check of Russian video-recording equipment.

After setting up an electrocardiogram for a 24-hour survey of his own heart health, Vagner terminated the test. In addition to investigating the effects of long-duration space travel on astronauts, he continued with setup and observation of our own planet using Earth photography. While the universe remain the ultimate unknown, there are still phenomena on Earth that scientists do not fully understand. For those particular mysteries, observations from station could prove eminently useful.

Space Station Upkeep a Priority as Astrobee Sweeps the Interior

As a free-flying, cube-shaped robot dubbed Astrobee zipped through the International Space Station today, the Expedition 63 trio aboard was occupied with upkeep and experiment maintenance tasks.

Astrobee is autonomous, and therefore no additional burden to the busy schedule of Commander Chris Cassidy of NASA and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner. Masterminded to assist the spare-faring crew with routine chores and give controllers on the ground an easy way to survey the station’s interior, the robot is currently flying about to capture additional video and imagery for later study.

Cassidy spent significant time in the Columbus laboratory module installing Fluidics hardware and setting it up for test runs. The experiment itself consists of three small transparent spheres with a centrifuge to move the liquids within. Data compiled from the investigation will one day improve applications in space, optimizing fuel systems, as well as on Earth, providing insight into how oceans work and the phenomenon of “rogue waves.” In addition, Cassidy replaced components in the Waste and Hygiene Compartment and performed life-support maintenance.

Vagner, meanwhile, helped with the life-support maintenance and serviced the Russian oxygen generator. With Ivanishin accompanying, they tackled cleaning air vents and dust filters to ensure the smooth running of the orbiting outpost. Smoke detectors within the Zarya module were also changed out during the housekeeping work.

The Russian crewmates contributed to the space station’s legacy as a microgravity testbed by furthering research objectives, with Ivanishin monitoring and identifying catastrophic events through the aid of Earth photography. Vagner added to the heart health study his counterpart had completed earlier in the week by setting up his own wearable monitor for a 24-hour electrocardiogram evaluation.

At 4:32 p.m. EDT, a planned reboost will put the orbiting laboratory in the proper positioning for the anticipated Soyuz launch of Expedition 64 on Oct. 14, followed by the landing of the current crew on Oct. 21.

Scans and Housekeeping Tasks Dominate with an Eye for the Future

The three Expedition 63 crewmates continued working on tasks aboard the International Space Station that will not only extend the outpost beyond its current 20-year tenure maximizing science in space, but also facilitate human travel deeper into the solar system.

Commander Chris Cassidy was again in the JAXA (Japan Aerospace Exploration Agency) Kibo laboratory module to continue setup with the Confocal Space Microscopy. The apparatus provides many advantages over conventional optical microscopy, some of which include the ability to control depth of field and collect sequential optical sections from thick biological specimens. Next up, Cassidy disconnected and stowed the Biomolecule Sequencer, which he had just used the day before with the Genes in Space 6 investigation.

The station commander also served as the test subject for additional ultrasound eye scans, performed by cosmonaut Ivan Vagner, who serves as the crew medical officer approximately 240 miles above Earth. It has now long been understood that crew members’ bodies change in a variety of ways during spaceflight, and some can even experience impaired vision. Gathering data on how ocular health changes during the course of a months-long mission will help inform scientists and mission planners for future expeditions requiring greater time in space and exploration at different destinations, like the Moon and Mars.

Vagner, along with fellow cosmonaut Anatoly Ivanishin, spent time transferring waste to the two cargo vehicles docked at station, Progress 75 and Progress 76. In addition, Ivanishin wiped down surfaces in the Russian segment and disconnected his electrocardiogram monitor after a full 24-hour test that surveyed the health of his heart.

NASA commercial provider Northrop Grumman announced that it will name the NG-14 Cygnus spacecraft, the cargo ship slated to launch Sept. 29 to replenish station with supplies and new science, after astronaut Kalpana Chawla. It is the company’s tradition to name each Cygnus after an individual who has played a pivotal role in human spaceflight, and Chawla was selected in honor of her prominent place in history as the first woman of Indian descent to go to space.

Studies on the Human Condition Take Flight Along With Piloting Investigation

Expedition 63 Commander Chris Cassidy of NASA and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner spent a full day after the holiday weekend on investigations that will help demystify the effects of space on the human body, as well as some routine maintenance tasks to ensure the health of the International Space Station — now in its 20th year supporting crews in space.

In the JAXA (Japan Aerospace Exploration Agency) Kibo laboratory module, Cassidy spent the first part of his Tuesday with Aquatic Habitat, a unique closed-water circulatory aquarium capable of accommodating small freshwater fish such as medaka or zebrafish, which serve as ideal subjects in the study of vertebrates. The station commander performed lens collection for the Confocal Space Microscopy setup and closeout, helping to maintain the microscope capable of providing fluorescence images of biological samples that inform scientists on the ground about the fundamental nature of cellular and tissue structure and functions. Cassidy later used the Biomolecule Sequencer for Genes in Space 6, which evaluates how exposure to radiation affects the long-term health of astronauts. The investigation, part of a series, will aid in finding the optimal DNA repair mechanisms that cells use in microgravity.

Meanwhile, on the Russian segment, Ivanishin furthered understanding in how the heart performs during long-duration spaceflight by setting up, and then wearing, an electrocardiogram for a 24-hour period. The crew member also wiped down instrumentation during routine maintenance and configured Earth-observation hardware to capture changes in the planet below.

Vagner, too, did some housekeeping for the outpost, performing transfers to Progress 75 cargo ship tanks in anticipation of its deorbit in Earth’s atmosphere sometime in December. The cosmonaut also focused on the Pilot-T piloting spacecraft and robots study, which uses a mathematical assessment model to develop recommendations and improve the training for cosmonauts expected to perform complicated operator tasks such as docking or flying spacecraft.
