More than 30,000 scientists gathered in Washington, D.C. during the second week of December – many to show off the work of NASA’s science volunteers! The American Geophysical Union held its annual meeting of professionals this month – the world’s largest gathering of Earth and Space Scientists. Here’s what they were talking about.
Eighteen NASA-sponsored project team members presented discoveries made with volunteers on topics from solar eclipses to global freshwater lake monitoring and exoplanet research. Overall, 175 posters and presentations featured the work of volunteers (up from 137 in 2023). Overall, 363 scientists and presenters at the conference described themselves as being involved in citizen science research (up from 201 in 2023). Two dozen scientists at the meeting gathered for lunch in the atrium of the National Portrait Gallery to talk about doing NASA science with volunteers. They discussed projects about asteroids, landslide hazard prediction, solar eclipse science, water quality, martian clouds, and more. Science done with volunteers is often called citizen science or participatory science – it does not require citizenship in any particular country. “Between the immense datasets being collected by NASA missions and the perennial need to open wide the doors to science so everyone can experience the joy and rewards of doing research together, citizen science is needed now more than ever!” said Sarah Kirn, the participatory science strategist at the Gulf of Maine Research Institute in Portland.” You can join one of NASA’s many participatory science projects right here!

NASA has selected multiple companies to expand the agency’s Near Space Network’s commercial direct-to-Earth capabilities services, which is a mission-critical communication capability that allows spacecraft to transmit data directly to ground stations on Earth.
The work will be awarded under new Near Space Network services contracts that are firm-fixed-price, indefinite-delivery/indefinite-quantity contracts. Project timelines span from February 2025 to September 2029, with an additional five-year option period that could extend a contract through Sept. 30, 2034. The cumulative maximum value of all Near Space Network Services contracts is $4.82 billion.
Some companies received multiple task orders for subcategories identified in their contracts. Awards are as follows:
Intuitive Machines of Houston will receive two task order awards on its contract for Subcategory 1.2 GEO to Cislunar Direct to Earth (DTE) Services and Subcategory 1.3 xCislunar DTE Services to support NASA’s Lunar Exploration Ground Segment, providing additional capacity to alleviate demand on the Deep Space Network and to meet the mission requirements for unique, highly elliptical orbits. The company also previously received a task order award for Subcategory 2.2 GEO to Cislunar Relay Services. Kongsberg Satellite Services of Tromsø, Norway, will receive two task order awards on its contract for Subcategory 1.1 Earth Proximity DTE and Subcategory 1.2 to support science missions in low Earth orbit and NASA’s Lunar Exploration Ground Segment, providing additional capacity to alleviate demand on the Deep Space Network. SSC Space U.S. Inc. of Horsham, Pennsylvania, will receive two task order awards on its contract for Subcategories 1.1 and 1.3 to support science missions in low Earth orbit and to meet the mission requirements for unique, highly elliptical orbits. Viasat, Inc. of Duluth, Georgia, will be awarded a task order on its contract for Subcategory 1.1 to support science missions in low Earth orbit. The Near Space Network’s direct-to-Earth capability supports many of NASA’s missions ranging from climate studies on Earth to research on celestial objects. It also will play a role in NASA’s Artemis campaign, which calls for long-term exploration of the Moon.
NASA’s goal is to provide users with communication and navigation services that are secure, reliable, and affordable, so that all NASA users receive the services required by their mission within their latency, accuracy, and availability requirements.
These awards demonstrate NASA’s ongoing commitment to fostering strong partnerships with the commercial space sector, which plays an essential role in delivering the communications infrastructure critical to the agency’s science and exploration missions.
As part of the agency’s SCaN (Space Communications and Navigation) Program, teams at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, will carry out the work of the Near Space Network. The Near Space Network provides missions out to 1.2 million miles (2 million kilometers) with communications and navigation services, enabling spacecraft to exchange critical data with mission operators on Earth. Using space relays in geosynchronous orbit and a global system of government and commercial direct-to-Earth antennas on Earth, the network brings down terabytes of data each day.

A method for evaluating thermophysical properties of metal alloys
Simulation of the solidification of metal alloys, a key step in certain industrial processes, requires reliable data on their thermophysical properties such as surface tension and viscosity. Researchers propose comparing predictive models with experimental outcomes as a method to assess these data.
Scientists use data on surface tension and viscosity of titanium-based alloys in industrial processes such as casting and crystal growth. Non-Equilibrium Solidification, Modelling for Microstructure Engineering of Industrial Alloys, an ESA (European Space Agency) investigation, examined the microstructure and growth of these alloys using the station’s Electromagnetic Levitator. This facility eliminates the need for containers, which can interfere with experiment results.
European Space Agency (ESA) astronaut Alexander Gerst is shown in the Columbus module of the International Space Station during the installation of the Electromagnetic Levitator.ESA/Alexander Gerst Overview of techniques for measuring thermal diffusion
Researchers present techniques for measuring thermal diffusion of molecules in a mixture. Thermal diffusion is measured using the Soret coefficient – the ratio of movement caused by temperature differences to overall movement within the system. This has applications in mineralogy and geophysics such as predicting the location of natural resources beneath Earth’s surface.
A series of ESA investigations studied diffusion, or how heat and particles move through liquids, in microgravity. Selectable Optical Diagnostics Instrument-Influence of VIbrations on DIffusion of Liquids examined how vibrations affect diffusion in mixtures with two components and SODI-DCMIX measured more-complex diffusion in mixtures of three or more components. Understanding and predicting the effects of thermal diffusion has applications in various industries such as modeling of underground oil reservoirs.

Researchers validated the concept of using ferrofluid technology to operate a thermal control switch in a spacecraft. This outcome could support development of more reliable and long-lasting spacecraft thermal management systems, increasing mission lifespan and improving crew safety.
Überflieger 2: Ferrofluid Application Research Goes Orbital analyzed the performance of ferrofluids, a technology that manipulates components such as rotors and switches using magnetized liquids and a magnetic field rather than mechanical systems, which are prone to wear and tear. This technology could lower the cost of materials for thermal management systems, reduce the need for maintenance and repair, and help avoid equipment failure. The paper discusses possible improvements to the thermal switch, including optimizing the geometry to better manage heat flow.
