Space Station Science Highlights: Week of October 1, 2018













ISS - Expedition 57 Mission patch.

Oct. 5, 2018

It was a busy week aboard the International Space Station as Expedition 56 Commander Drew Feustel and Flight Engineer Ricky Arnold of NASA, along with Flight Engineer and Soyuz Commander Oleg Artemyev of the Russian space agency Roscosmos returned to Earth. With their departure comes the start of Expedition 57 and a new space station commander.

Feustel, Expedition 56 Commander, handed off the station command to Alexander Gerst of the European Space Agency during a Change of Command Ceremony on Wednesday.

In addition to all of the crew excitement, science was being conducted in the areas of human research, technology development, plant biology and more.

Blood and Saliva samples collected for ambient return

Protecting crew health is important as NASA prepares for long duration, deep-space missions. Functional Immune studies previously uninvestigated areas of the body’s immune response and if spaceflight alters a crew member’s susceptibility to disease.

The immune system is a complex weaving of biological structures and processes. Decreased activity in just one piece can cause changes in disease risk within the human body. Studies have shown in microgravity there are immune system modifications. This may create an environment where, in some crew members, rashes, unusual allergies and latent virus reactivation may present themselves.

This week, crew members collected saliva and blood samples for an ambient return aboard the 54S Soyuz spacecraft.

Japanese satellite prepares for upcoming deployments

The JEM Small Satellite Orbital Deployer (J-SSOD) provides a novel, safe, small satellite launching capability to the space station. The J-SSOD is a unique satellite launcher, handled by the Japanese Experiment Module Remote Manipulator System (JEMRMS), which provides containment and deployment mechanisms for several individual small satellites.

This week, the crew installed the J-SSOD-10 onto the Multipurpose Experiment Platform (MPEP) in preparation for this weekend’s satellite deployments.

Arabidopsis plants thinned to allow for more growth

Understanding how plants grow and thrive in harsh environments, both on Earth and in space, is important for advancements in agriculture. The Advanced Plant Habitat Facility (Plant Habitat) is a fully automated facility used to conduct plant bioscience research and provides a large, enclosed, environmentally controlled chamber aboard the space station.

The crew performed plant thinning as a part of the Plant Habitat-1 investigation. In this activity, the young Arabidopsis plants, small flowering plants related to cabbage and mustard, were thinned. This gives the remaining plants a better chance to continue their growth.

Other work was done on these investigations:

- BEST seeks to advance use of sequencing DNA and RNA in space: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7687

- Food Acceptability examines changes in how food appeals to crew members during their time aboard the station. Acceptability of food – whether crew members like and actually eat something – may directly affect crew caloric intake and associated nutritional benefits: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7562

- The Sally Ride EarthKAM program allows students to 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: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=87

- The Life Sciences Glovebox (LSG) is a sealed work area that accommodates life science and technology investigations in a workbench-type environment. Due to its larger size, two crew members can work in the LSG simultaneously: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Facility.html?#id=7676

- MATISS investigates the antibacterial properties of materials in space for possible application in future spacecraft: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=7333

- MobiPV aims to improve the efficiency of activity execution by giving crewmembers a wireless set of wearable, portable devices that utilize voice navigation and a direct audio/video link to ground experts: https://www.nasa.gov/mission_pages/station/research/experiments/explorer/Investigation.html?#id=1818
