Space Station Science Highlights: Week of September 24, 2018

ISS – Expedition 56 Mission patch.

Sept. 28, 2018

The Japan Aerospace Exploration Agency (JAXA) H-II Transfer Vehicle-7 (HTV-7) resupply ship arrived at the International Space Station on Thursday, packed with more than five tons of science and supplies for the Expedition 56 crew.

Included among the newly-arrived science is the station’s Life Sciences Glovebox, a state-of-the-art microgravity research facility that enables high-value biological research in low-Earth orbit.

Students from around the globe take photos from space station

Not everyone can go to space, but everyone can see Earth from an astronaut’s perspective with the Sally Ride Earth Knowledge Acquired by Middle School Students (Sally Ride EarthKAM) program. Students can remotely control a digital camera mounted on the space station and use it to take photographs of coastlines, mountain ranges and other features and phenomena. The images are posted online where the public and participating classrooms can view Earth from the station’s unique vantage point.

This week, the crew replaced a 50mm lens with an 85mm lens and initiated an imaging session for the more than 27,000 students stemming from 33 countries involved in the program’s 63rd mission. See recent EarthKAM images here: https://www.earthkam.org/ek-images

Investigation studies complex assemblies in space

The assembly of colloidal and nanostructures is important for technological applications and for a fundamental understanding of self-assembly processes that are abundant in nature and in living matter. A better understanding of complex assembly will lead to the ability to design and grow man-made nanostructured materials with life-like functionality. The Advanced Colloids Experiment-Temperature-2 (ACE-T-2) looks at the assembly of complex structures from micron-scale colloidal particles interacting via tunable attractive interactions.

The samples contain suspensions of colloidal particles that, upon nearing the critical solvent temperature, give rise to critical interactions between the particles. Regulating the temperature enables control of the particle interactions, leading to the growth of complex structures.

This week, the crew performed a sample module exchange within the Light Microscopy Module (LMM), contained within the Fluid Integration Rack (FIR).

Fast Neutron Spectrometer moves to Destiny Lab

Neutron spectrometers are used to make a wide range of measurements, including studies of a planetary body’s composition and measuring the flux of high-energy neutrons that could be harmful to humans. The Fast Neutron Spectrometer (FNS) investigation studies a new neutron measurement technique that is better suited for the mixed radiation fields found in deep space. Future operated and exploration missions benefit from clearer, more error-free measurement of the neutron flux present in an environment with multiple types of radiation.

The investigation employs a set of simple exposure coupons that allow visual comparison of the effects of the space environment to a well-characterized white reference coating for this environment. Comparing photographs of these newly developed coatings to a white reference sample provides researchers information on the stability of the coatings. Animation Credit: NASA.

This week, the crew relocated the FNS from Node 1 to its new location in the Destiny Laboratory.
