Scans and Housekeeping Tasks Dominate with an Eye for the Future













ISS - Expedition 63 Mission patch.

September 9, 2020

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.
