Dragon Packing, Eye Science and Spacewalk Preps Today












ISS - Expedition 56 Mission patch.

The Expedition 56 crew has nearly completed loading the SpaceX Dragon resupply ship with cargo for retrieval back on Earth this Friday. The orbital residents are also busy with an intense day of space research and Russian spacewalk preparations.

Dragon is due to be released Friday at 12:37 p.m. EDT from the International Space Station carrying several tons of experiment results and orbital lab hardware. The crew has been packing the crucial research samples this week inside specialized, portable freezers onboard the commercial space freighter.

SpaceX technicians will pick up Dragon with its precious cargo after it splashes down in the Pacific Ocean and return to shore in southern California. Scientists and engineers will then begin the process of analyzing the critical space science and refurbishing station hardware.

Astronauts Serena Auñón-Chancellor and Alexander Gerst spent Wednesday morning helping doctors understand how living in space impacts the human eye. They are exploring the hypothesis that upward fluid shifts in the body caused by microgravity increases pressure on the brain possibly pushing against the eyes. This may affect the shape of the eye and permanently affect vision.

Cosmonauts Oleg Artemyev and Sergey Prokopyev are getting ready for a spacewalk on Aug. 15. The duo reviewed the translation paths to their work sites on the outside of the station’s Russian segment. During the near seven-hour excursion, the spacewalkers will hand-deploy four tiny satellites, install antennas and cables on the Zvezda service module and collect exposed science experiments.

A host of life science studies being returned aboard Dragon looked at cancer therapies, gut microbes, and a variety of other biological phenomena. Samples collected from those studies, including the experiment hardware housing the research, are being transferred from the station and stowed inside the Dragon.

The AngieX Cancer Therapy investigation is completing its run today with NASA astronaut Serena Auñón-Chancellor finalizing research operations inside the Microgravity Science Glovebox. The experiment tested a treatment that targets tumors and the resulting samples are being stowed inside Dragon science freezers.

Rodents studied for the Rodent Research-7 experiment to understand how microbes interact with the gut in space are being returned Friday. Biological samples observed in July for the Micro-11 human reproduction study are also being cold stowed aboard Dragon.
