Space Station Science Highlights: Week of June 11, 2018

June 15, 2018

Scientific work continued aboard the International Space Station this week, as crew members collected biological samples, observed crystal growth, tested grip force, and more.

NASA astronaut Serena Auñón-Chancellor, Alexander Gerst of the European Space Agency (ESA), and Sergey Prokopyev of Roscosmos recently joined Expedition 56 and began pitching in on these and other science tasks.

Here are more details on this week’s scientific work aboard your orbiting laboratory:

Crystal close-ups

Advanced Colloids Experiment-Temperature-7 (ACE-T-7) investigates self-assembled colloids, which are complex three-dimensional structures made from small particles suspended within a fluid medium. These are vital to design of advanced optical materials and active devices.

Activity on ACE-T-7 this week included mixing of Capillaries 1, 2 and 3 based on observed crystal formation. Science imaging of all three capillaries continues, as well as adjusting camera settings on Capillary 1 to optimize surface crystal images.

That feeling in your gut

Fecal samples were collected for JAXA’s Multi-Omics experiment and placed in the Minus Eighty-Degree Celsius Laboratory Freezer for ISS (MELFI). Crew also collected saliva samples for the investigation.

Multi-Omics evaluates how the space environment and prebiotics affect an astronauts’ immune function, combining data on changes in the gut microbial composition, metabolites profiles, and the immune system.

Get a grip

The European Space Agency’s GRIP investigation studies the effects of long-duration spaceflight and the forces of gravity and inertia on grip force and upper limb movements during manipulation of objects. Results may provide insight into potential hazards as astronauts move between different gravitational environments, as well as support design and control of human-computer interactions in challenging environments such as space. Information from the investigation also could be useful for rehabilitation of impaired upper limb control as a result of neurological diseases in patients on Earth.

This week, the crew completed the third of three GRIP operations in the supine position, or lying down facing up.

Blood, breath, and no tears

Crew collected breath and blood samples for CSA’s Marrow investigation, which looks at the effect of microgravity on bone marrow. It is believed that microgravity has a negative effect on the bone marrow and the blood cells produced in bone marrow, similar to the effects of long-duration bed rest on Earth.

This week also included collection of blood samples for JAXA’s CFE and Medical Proteomics investigations, Vascular Echo, Functional Immune and Probiotics.
