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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A fisheye lens attached to an electronic still camera was used to capture this image of NASA astronaut Don Pettit.NASA Science ideas are everywhere. Some of the greatest discoveries have come from tinkering and toying with new concepts and ideas. NASA astronaut Don Pettit is no stranger to inventing and discovering. During his previous missions, Pettit has contributed to advancements for human space exploration aboard the International Space Station resulting in several published scientific papers and breakthroughs.
Pettit, accompanied by cosmonauts Alexey Ovchinin and Ivan Vagner, will launch to the orbiting laboratory in September 2024. In preparation for his fourth spaceflight, read about previous “science of opportunity” experiments Pettit performed during his free time with materials readily available to the crew or included in his personal kit.
Freezing Ice in Space
Thin ice under polarized light frozen aboard the International Space Station.NASA Have you ever noticed a white bubble inside the ice in your ice tray at home? This is trapped air that accumulates in one area due to gravity. Pettit took this knowledge, access to a -90° Celsius freezer aboard the space station, and an open weekend to figure out how water freezes in microgravity compared to on Earth. This photo uses polarized light to show thin frozen water and the visible differences from the ice we typically freeze here on Earth, providing more insight into physics concepts in microgravity.
Space Cup
NASA astronaut Don Pettit demonstrates how surface tension, wetting, and container shape hold coffee in the space cup.NASA Microgravity affects even the most mundane tasks, like sipping your morning tea. Typically, crews drink beverages from a specially sealed bag with a straw. Using an overhead transparency film, Pettit invented the prototype of the Capillary Beverage, or Space Cup. The cup uses surface tension, wetting, and container shape to mimic the role of gravity in drinking on Earth, making drinking beverages in space easier to consume and showing how discoveries aboard station can be used to design new systems.
Planetary Formation

Astronaut Don Pettit demonstrates a mixture of coffee grounds and sugar sticking together in microgravity to understand planetary formation. NASA Using materials that break into very small particles, such as table salt, sugar, and coffee, Pettit experimented to understand planetary formation. A crucial early step in planet formation is the aggregation or clumping of tiny particles, but scientists do not fully understand this process. Pettit placed different particulate mixtures in plastic bags, filled them with air, thoroughly shook the bags, and observed that the particles clumped within seconds due to what appears to be an electrostatic process. Studying the behavior of tiny particles in microgravity may provide valuable insight into how material composition, density, and turbulence play a role in planetary formation.
Orbital Motion
Charged water particles orbit a knitting needle, showing electrostatic processes in space. NASA Knitting needles made of different materials arrived aboard station as personal crew items. Pettit electrically charged the needles by rubbing each one with paper. Then, he released charged water from a Teflon syringe and observed the water droplets orbit the knitting needle, demonstrating electrostatic orbits in microgravity. The study was later repeated in a simulation that included atmospheric drag, and the 3D motion accurately matched the orbits seen in the space station demonstration. These observations could be analogous to the behavior of charged particles in Earth’s magnetic field and prove useful in designing future spacecraft systems.
Astrophotography

Bottom: Star trails photographed by NASA astronaut Don Pettit in March of 2012.NASA An innovative photographer, Pettit has used time exposure, multiple cameras, infrared, and other techniques to contribute breathtaking images of Earth and star trails from the space station’s unique viewpoint. These photos contribute to a database researchers use to understand Earth’s changing landscapes, and this imagery can inspire the public’s interest in human spaceflight.

One of the winning papers was co-authored by Russanne Low, PhD, Institute for Global Environmental Strategies (IGES). Low is a member of the NASA Earth Science Education Collaborative (NESEC), a NASA Science Activation project, and science lead for the Global Learning & Observations to Benefit the Environment (GLOBE) Mosquito Habitat Mapper.
The paper – Integrating global citizen science platforms to enable next-generation surveillance of invasive and vector mosquitoes – was published as part of a special issue of Insects on Citizen Science Approaches to Vector Surveillance. It is in the top 5% of all research outputs scored by Altmetric, which is a high-level measure of the quality and quantity of online attention that it has received. The scoring algorithm takes various factors into account, such as the relative reach of the different sources of attention. The paper has been cited 23 times.
Papers were selected by the journal’s Award Committee according to the following criteria:
– Scientific merit and broad impact;
– Originality of the research objectives and/or the ideas presented;
– Creativity of the study design or uniqueness of the approaches and concepts;
– Clarity of presentation;
