JAXA (Japan Aerospace Exploration Agency) researchers examined the structures of four titanium-based compounds solidified in levitators in microgravity and on the ground and found that the internal microstructures were generally similar. These results could support development of new materials for use in space manufacturing.
To produce glass or metal alloys on Earth, raw materials are placed into a container and heated. But reactions between the container and the materials can cause imperfections. The JAXA Electrostatic Levitation Furnace can levitate, melt, and solidify materials without a container. The facility enables measurement of the thermophysical properties of high temperature melts and could accelerate development of innovative materials such as heat resistant ceramics for use in the aerospace and energy industries.
JAXA (Japan Aerospace Exploration Agency) astronaut Akihiko Hoshide works with the Electrostatic Levitation Furnace.European Space Agency/Thomas Pesquet Satellite 3D imaging of a Peruvian tropical forest demonstrated that measuring leaf traits with remote sensing may provide more accurate predictions of biomass production than structure data such as tree height. Carbon stored or sequestered in forests can help offset emissions that cause climate change, and improved estimates of tropical forest biomass could allow researchers to better evaluate these ecosystems and their offset contributions.
Global Ecosystem Dynamics Investigation (GEDI) provides high-resolution global observations of Earth’s forests and topography. These observations provide information on carbon and water cycling processes, biodiversity, and habitat, including quantifying carbon stored in vegetation and the potential for future carbon storage. The researchers suggest that estimates of tropical forest biomass could be further improved with data from new satellite missions and by integrating GEDI with dynamic vegetation models that include trait data.

NASA/Nick Hague Research indicates that refractive eye surgery is safe, effective, and suitable for astronauts. The study documented stable vision in two astronauts who, a few years prior to flight, underwent photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK), respectively. These visual correction procedures can reduce the logistical complications of wearing glasses or contact lenses in space.
International Space Station Medical Monitoring collects health data from crew members before, during, and after spaceflight. The medical evaluation requirements, including vision assessment, apply to all crew members and are part of efforts by all international partners to maintain crew health, ensure mission success, and enable crew members to return to normal life on Earth after their missions.
NASA astronauts Terry Virts (bottom) and Scott Kelly (top) perform eye exams as part of ongoing studies into crew vision health. NASA JAXA researchers report that accurately assessing the velocity of airflow in front of a spreading flame makes it possible to predict the flammability of thin, flat materials in microgravity. These results mean it could be possible to use ground tests to predict the flammability of solid materials and thus ensure fire safety in spacecraft and space habitations.
The JAXA Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE) investigation tested the flammability of various solid materials in different configurations, including filter paper. Microgravity significantly affects combustion phenomena such as the spread of flame over solid materials; while flames cannot spread over solid materials under low-speed oxygen flow in Earth’s gravity, they can in microgravity due to the lack of buoyancy. Testing of the flammability of materials for spacecraft previously has not considered the effect of gravity, and results from this investigation could address this issue, significantly improving fire safety on future exploration missions.

Credit: NASA / Langley Research Center NASA Administrator Bill Nelson will represent the agency during a Congressional Gold Medal ceremony at 3 p.m. EDT Wednesday, Sept. 18, recognizing the women who contributed to the space race, including the NASA mathematicians who helped land the first astronauts on the Moon under the agency’s Apollo Program.
Hosted by House Speaker Mike Johnson, the Congressional Gold Medal Ceremony will take place inside Emancipation Hall at the U.S. Capitol in Washington. Nelson is expected to be among the speakers.
The event will stream live on the speaker’s YouTube channel. The agency will share a direct link on this advisory in advance of the event.
Media without current congressional credentials on the Hill interested in participating in the event must RSVP by Sept. 13, to Abby Ronson at: abby.ronson@mail.house.gov.
Medal Information
Introduced by Rep. Eddie Bernice Johnson on Feb. 27, 2019, H.R.1396 – Hidden Figures Congressional Gold Medal Act – was signed into law later that year. Awards will include:
Congressional Gold Medal to Katherine Johnson, in recognition of her service to the United States as a mathematician Congressional Gold Medal to Dr. Christine Darden, for her service to the United States as an aeronautical engineer Congressional Gold Medals in commemoration of the lives of Dorothy Vaughan and Mary Jackson, in recognition of their service to the United States during the space race Congressional Gold Medal in recognition of all the women who served as computers, mathematicians, and engineers at the National Advisory Committee for Aeronautics and NASA between the 1930s and the 1970s.

Image: ESA’s Metal 3D Printer has produced the first metal part ever created in space.
The technology demonstrator, built by Airbus and its partners, was launched to the International Space Station at the start of this year, where ESA astronaut Andreas Mogensen installed the payload in the European Drawer Rack of ESA’s Columbus module. In August, the printer successfully printed the first 3D metal shape in space.
This product, along with three others planned during the rest of the experiment, will return to Earth for quality analysis: two of the samples will go to ESA’s technical heart in the Netherlands (ESTEC), another will go to ESA’s astronaut training centre in Cologne (EAC) for use in the LUNA facility, and the fourth will go to the Technical University of Denmark (DTU).
As exploration of the Moon and Mars will increase mission duration and distance from Earth, resupplying spacecraft will be more challenging. Additive manufacturing in space will give autonomy for the mission and its crew, providing a solution to manufacture needed parts, to repair equipment or construct dedicated tools, on demand during the mission, rather than relying on resupplies and redundancies.
ESA’s technology demonstrator is the first to successfully print a metal component in microgravity conditions. In the past, the International Space Station has hosted plastic 3D printers.
