Discover groundbreaking research that is helping pave the way for future space exploration and support systems in orbit.

The mission to the International Space Station involves a variety of experiments and studies, including C4 Photosynthesis in Space (APEX-09), which focuses on the role of plants in providing food and promoting the well-being of astronauts on deep space missions.

Under the leadership of principal investigator Pubudu Handakumbura from the Pacific Northwest National Laboratory, this project examines the effects of microgravity on the carbon dioxide capture mechanisms of different types of grasses, known as C3 and C4. By studying the molecular changes that occur in plants exposed to spaceflight stressors, researchers hope to gain a better understanding of photosynthesis in space and how plants respond to different environments. This knowledge could inform the development of bio-regenerative support systems for future missions and advancements in plant growth on Earth.

Another project, Killick-1: A GNSS Reflectometry CubeSat for Measuring Sea Ice Thickness and Extent (Nanoracks KILLICK-1), explores the use of a technique called Global Navigation Satellite System reflectometry (GNSS-R) to monitor ocean phenomena and improve climate models. Led by co-investigator Desmond Power from C-CORE, this project involves testing the use of GNSS-R to measure sea ice thickness. Not only does this project support the development of space and science capabilities in Newfoundland and Labrador, Canada, but it also provides hands-on experience for over 100 undergraduate and graduate engineering students.

The low-cost, lightweight, and energy-efficient GNSS-R technology has potential applications on Earth, including providing valuable data for weather and climate models and enhancing our understanding of ocean phenomena like surface winds and storm surge.

The Multi-resolution Scanner (MRS) Payload for Astrobee (Multi-Resolution Scanning) is another innovative project that aims to automate 3D sensing, mapping, and situational awareness systems. Led by Marc Elmouttie from Australia's national science agency CSIRO, in collaboration with The Boeing Company, this project will use a free-flying robot called Astrobee to create 3D maps inside the space station. The scanner combines technologies developed by CSIRO's mining and robotics teams to compensate for any weaknesses in individual systems, resulting in highly accurate 3D data and trajectory information. This technology could have a wide range of uses, including autonomous spacecraft operation, spacecraft inspection and maintenance, and autonomous vehicle operations on other celestial bodies.

The Nano Particle Haloing Suspension investigation, led by Stuart J. Williams from the University of Louisville Department of Mechanical Engineering, explores how nanoparticles and microparticles interact within an electrical field. By utilizing a process called nanoparticle haloing, which involves charged nanoparticles, researchers hope to improve the efficiency of quantum-dot synthesized solar cells. Conducting these experiments in microgravity provides valuable insights into the relationship between particle shape, charge, concentration, and interaction. This investigation is supported by NASA's Established Program to Stimulate Competitive Research (EPSCoR), which partners with government, higher education, and industry to enhance research infrastructure and capacity for research and development.

Overall, these projects demonstrate the diverse and groundbreaking research taking place on the International Space Station, with potential implications for not only space exploration but also advancements in technology and understanding of our own planet.
