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.
