      See more space station research achievements and findings in the Annual Highlights of Results publication, and read highlights of results published between October 2022 and October 2023 below:
      A New Spin on Pulsars
      A view of NICER, attached to the space station’s exterior multipurpose payload shelving unit.NASA Neutron stars, ultra-dense matter left behind when massive stars explode as supernovas, are also called pulsars because they spin and emit X-ray radiation in beams that sweep the sky like lighthouses. The Neutron star Interior Composition Explorer (NICER) collects this radiation to study the structure, dynamics, and energetics of pulsars. Researchers used NICER data to calculate rotations of six pulsars and update mathematical models of their spin properties. Precise measurements enhance the understanding of pulsars, including their production of gravitational waves, and help address fundamental questions about matter and gravity.
      Learning from Lightning
      The space station’s robotic arm maneuvers the Atmosphere-Space Interactions Monitor, seen at the top of the image, for light testing. NASA Atmosphere-Space Interactions Monitor (ASIM) studies how upper-atmospheric electrical discharges generated by severe thunderstorms affect Earth’s atmosphere and climate. These events occur well above the altitudes of normal lightning and storm clouds. Using ASIM data, researchers reported the first detailed observations of  development of a of negative leader, or initiation of a flash, from in-cloud lightning. Understanding how thunderstorms disturb the high-altitude atmosphere could improve atmospheric models and climate and weather predictions.
      Regenerating Tissue in Space
      Tissue Regeneration-Bone Defect (Rodent Research-4 (CASIS)), sponsored by the ISS National Lab, examined wound healing mechanisms in microgravity. Researchers found that microgravity affected the fibrous and cellular components of skin tissue. Fibrous structures in connective tissue provide structure and protection for the body’s organs. This finding is an initial step to use connective tissue regeneration to treat disease and injuries for future space explorers.
      Mighty Muscles in Microgravity
      Installation of the Mouse Habitat Unit (MHU) in the station’s Cell Biology Experiment Facility. NASA/JAXA JAXA (Japan Aerospace Exploration Agency) developed the Multiple Artificial-gravity Research System (MARS), which generates artificial gravity in space. Three JAXA investigations, MHU-1, MHU-4, and MHU-5, used the artificial-gravity system to examine the effect on skeletal muscles from different gravitation loads – microgravity, lunar gravity (1/6 g), and Earth gravity (1 g). Results show that lunar gravity protects against loss of some muscle fibers but not others. Different gravitational levels may be needed to support muscle adaptation on future missions.
      Better Ultrasound Images
      JAXA astronaut Akihiko Hoshide uses the station’s ultrasound device to image the femoral artery in his right leg. NASA Vascular Echo, an investigation from CSA (Canadian Space Agency), examined changes in blood vessels and the heart during and after spaceflight using ultrasound and other measures. Researchers compared 2D ultrasound technology with a motorized 3D ultrasound and found that 3D is more accurate. Better measurements could help maintain crew health in space and quality of life for people on Earth.
      This is Your Brain in Space
      ESA astronaut Thomas Pesquet with a preflight scan of his brain for the Brain-DTI investigation. ESA/NASA The Brain-DTI investigation from ESA (European Space Agency) tested whether the brain adapts to weightlessness by using previously untapped connections between neurons. MRI scans of crew members before and after spaceflight demonstrate functional changes in specific brain regions, confirming the adaptability and plasticity of the brain under extreme conditions. This insight supports the development of ways to monitor brain adaptations and countermeasures to promote healthy brain function in space and for those with brain-related disorders on Earth.
      Improving Solar Materials
      The MISSE-FF platform is used to test how exposure to space affects materials, including those used for solar power in space.NASA Metal halide perovskite (MHP) materials convert sunlight into electrical energy and show promise for use in thin-film solar cells in space due to low cost, high performance, suitability for in-space manufacturing, and defect and radiation tolerance. For Materials International Space Station Experiment-13-NASA (MISSE-13-NASA), which continues a series investigating how space affects various materials, researchers exposed perovskite thin films to space for ten months. Results confirmed their durability and stability in this environment. This finding could lead to improvements in MHP materials and devices for space applications such as solar panels.
      Understanding Bubbles in Foams
      A sample cell for the FOAM investigation on the space station.NASA Wet foams are dispersions of gas bubbles in a liquid matrix. An ESA investigation, FSL Soft Matter Dynamics or FOAM, examines coarsening, a thermodynamic process where large bubbles grow at the expense of smaller ones. Researchers determined the coarsening rates for various types of foams and found close agreement with theoretical predictions. A better understanding of foam properties could help scientists improve these substances for a variety of uses, including firefighting and water treatment in space and making detergents, food, and medicine on Earth.
      Answering Burning Questions
      A sample of composite cotton and fiberglass fabric burns during Saffire-IV.NASA Fire is a constant concern in space. The Saffire series of experiments studies flame conditions in microgravity using empty Cygnus resupply spacecraft that have undocked from the space station. Saffire-IV examined fire growth with different materials and conditions and showed that a technique called color pyrometry can determine the temperature of a spreading flame. The finding helps validate numerical models of flame properties in microgravity and provides insight into fire safety on future missions.
      The Robot Hop
      An Astrobee robot performs a self-tossing maneuver on the space station.NASA Astrobatics tests robotic movement using hopping or self-toss maneuvers by the station’s Astrobee robots. In low gravity, robots could move faster, use less fuel, and cover otherwise impassable terrain with these maneuvers, expanding their orbital and planetary capabilities. Results verified the viability of the locomotion method and showed that it provides a greater range of distance. The work is a step toward autonomous robotic helpers in space and on other celestial bodies, potentially reducing the need to expose astronauts to risky environments.

      Plants off the Planet
      Plants can be used in regenerative life support systems, to provide food, and to contribute to the well-being of astronauts on future deep space exploration missions. C4 Photosynthesis in Space (APEX-09) examines how microgravity affects the mechanisms by which two types of grasses, known as C3 and C4, capture carbon dioxide from the atmosphere.
      “Plants respond to stressful conditions based on their genetic makeup and the environment,” said Pubudu Handakumbura, principal investigator with the Pacific Northwest National Laboratory. “We aim to uncover the molecular changes involved in plants exposed to spaceflight stressors and develop an understanding of the mechanisms of photosynthesis in space.” Results could clarify plant responses to stressful environments and inform the design of bio-regenerative support systems on future missions, as well as systems for plant growth on Earth.

      The ocean significantly affects the global climate. A technique called Global Navigation Satellite System reflectometry (GNSS-R), which receives satellite signals reflected from the surface of Earth, shows promise as a way to monitor ocean phenomena and improve climate models. Killick-1: A GNSS Reflectometry CubeSat for Measuring Sea Ice Thickness and Extent (Nanoracks KILLICK-1) tests using this technique to measure sea ice. The project supports development of space and science capabilities in Newfoundland and Labrador, Canada, by providing hands-on experience with space systems and Earth observation. More than 100 undergraduate and graduate engineering students participated in the project.
      “The most exciting aspect of this project is that students have the opportunity to launch a mission into space,” said Desmond Power, a co-investigator with C-CORE of Canada. “It is also exciting to build a tiny satellite that does different things, including contributing to our knowledge of climate change.”
      GNSS-R technology is low-cost, light, and energy efficient. Its potential applications on Earth include providing data for weather and climate models and improving the understanding of ocean phenomena such as surface winds and storm surge.

      Multi-resolution Scanner (MRS) Payload for the Astrobee (Multi-Resolution Scanning) tests technology to automate 3D sensing, mapping, and situational awareness systems.
      “Our MRS on an Astrobee free-flying robot will create 3D maps inside the space station,” said Marc Elmouttie, project lead with the Australian Commonwealth Scientific and Industrial Research Organization. “The technology combines multiple sensors, which compensates for weaknesses in any one of them and provides very high-resolution 3D data and more accurate trajectory data to understand how the robot moves around in space.”
      The technology could be used for autonomous operation of spacecraft with minimal or no human occupancy where robots must sense the environment and precisely maneuver, including the lunar Gateway space station. Other uses could be to inspect and maintain spacecraft and for autonomous vehicle operations on other celestial bodies. Results also support improvements in robotic technologies for harsh and dangerous environments on Earth.

      The Nano Particle Haloing Suspension investigation examines how nanoparticles and microparticles interact within an electrical field. A process called nanoparticle haloing uses charged nanoparticles to enable precise particle arrangements that improve the efficiency of quantum-dot synthesized solar cells, according to Stuart J. Williams, principal investigator with the University of Louisville Department of Mechanical Engineering.
      Quantum dots are tiny spheres of semiconductor material with the potential to convert sunlight into energy much more efficiently. Conducting these processes in microgravity provides insight into the relationship between shape, charge, concentration, and interaction of particles.
      The investigation is supported by NASA’s Established Program to Stimulate Competitive Research (EPSCoR), which partners with government, higher education, and industry on projects to improve a research infrastructure and research and development capacity and competitiveness.
