Genetics, Vision and Earth Studies Aboard Station Today

The International Space Station was orbiting 257 miles above the English Channel when this photograph was taken of the Northern European countries of Denmark, Germany, Sweden and Poland. Japan’s H-II Transfer Vehicle-7, or HTV-7 resupply ship, is pictured at right attached the Harmony module.

Three Expedition 57 crew members are orbiting Earth today researching RNA sequencing and eye health aboard the International Space Station. The trio from the U.S., Germany and Russia also replaced combustion research hardware and activated Earth observation gear.

Flight Engineer Serena Auñón-Chancellor from NASA is helping scientists identify microbes and understand how their genetics change in space. She extracted and processed microbial samples today from swabbed station surfaces for later genetic sequencing using specialized hardware. Results will also help researchers observe how life adapts to the weightlessness of microgravity.

Auñón-Chancellor then observed and photographed samples for a protein crystal study to help doctors improve the development of disease-treating drugs. She then joined Commander Alexander Gerst of ESA (European Space Agency) for eye scans with an ultrasound device to learn how long-term missions affect vision.

Gerst started his day in the U.S. Destiny lab module replacing hardware inside the Combustion Integrated Rack that enables gas and flame studies. He later wrapped up the workday photographing how quartz and clay particles sediment in space.

Sergey Prokopyev of Roscosmos worked inside the Unity module setting up Earth photography gear for the long-running EarthKAM experiment. The study enables school students to remotely operate the station digital camera to photograph and download imagery of Earth landmarks such as coastlines and mountains.
