First NASA Neurodiversity Network Intern to Present at the American Geophysical Union Annual Conference
The NASA Science Activation Program’s NASA’s Neurodiversity Network (N3) project sponsors a summer internship program for high school students, in which learners on the autism spectrum are matched with NASA Subject Matter Experts. N3 intern Lillian Hall and mentor Dr. Juan Carlos Martinez Oliveros presented Lilly’s summer research project on December 9 at the 2024 American Geophysical Union conference in Washington, D.C. Their poster, entitled “Eclipse Megamovie: Image Processing”, represents the first time an N3 intern has co-authored a presentation at the prestigious AGU conference.
The NASA Citizen Science project, Eclipse Megamovie, is leveraging the power of citizen science to construct a high-resolution time-lapse of the Sun’s corona during the April 8, 2024 total solar eclipse. By coordinating the work of hundreds of participants along the path of totality, a substantial dataset of images was obtained. The goal of the project is to unveil dynamic transformations in the Sun’s atmosphere that are only visible during a total solar eclipse.
To process the vast quantity of imaging data collected, Lilly assisted Dr. Martinez Oliveros and other researchers in implementing a robust pipeline involving image calibration, registration, and co-location. Image registration techniques aligned the solar features across different frames, compensating for Earth’s rotation and camera movement. Finally, they used imaging techniques to enhance the signal-to-noise ratio, revealing subtle coronal structures and possible dynamics. This comprehensive data processing methodology has enabled the extraction of meaningful scientific information from the Eclipse Megamovie dataset.
Here’s what Lilly had to say: “Working with N3 has given me a chance to use my neurodiverse perspective to make an impact on NASA research. Through the processes of my project and the opportunity to share it at the American Geophysical Union conference, I am so grateful to have found my spot in the planetary science field I dream to continue researching in the future.”

5 Min Read NASA and Italian Space Agency Test Future Lunar Navigation Technology
The potentially record-breaking Lunar GNSS Receiver Experiment (LuGRE) payload will be the first known demonstration of GNSS signal reception on and around the lunar surface. Credits: NASA/Dave Ryan As NASA celebrates 55 years since the historic Apollo 11 crewed lunar landing, the agency also is preparing new navigation and positioning technology for the Artemis campaign, the agency’s modern lunar exploration program.
A technology demonstration helping pave the way for these developments is the Lunar GNSS Receiver Experiment (LuGRE) payload, a joint effort between NASA and the Italian Space Agency to demonstrate the viability of using existing GNSS (Global Navigation Satellite System) signals for positioning, navigation, and timing on the Moon.
During its voyage on an upcoming delivery to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, LuGRE would demonstrate acquiring and tracking signals from both the U.S. GPS and European Union Galileo GNSS constellations during transit to the Moon, during lunar orbit, and finally for up to two weeks on the lunar surface itself.
The Lunar GNSS Receiver Experiment (LuGRE) will investigate whether signals from two Global Navigation Satellite System (GNSS) constellations, the U.S. Global Positioning System (GPS) and European Union’s Galileo, can be tracked at the Moon and used for positioning, navigation, and timing (PNT). The LuGRE payload is one of the first demonstrations of GNSS signal reception and navigation on and around the lunar surface, an important milestone for how lunar missions will access navigation and positioning technology. If successful, LuGRE would demonstrate that spacecraft can use signals from existing GNSS satellites at lunar distances, reducing their reliance on ground-based stations on the Earth for lunar navigation.
Today, GNSS constellations support essential services like navigation, banking, power grid synchronization, cellular networks, and telecommunications. Near-Earth space missions use these signals in flight to determine critical operational information like location, velocity, and time.
NASA and the Italian Space Agency want to expand the boundaries of GNSS use cases. In 2019, the Magnetospheric Multiscale (MMS) mission broke the world record for farthest GPS signal acquisition 116,300 miles from the Earth’s surface — nearly half of the 238,900 miles between Earth and the Moon. Now, LuGRE could double that distance.
“GPS makes our lives safer and more viable here on Earth,” said Kevin Coggins, NASA deputy associate administrator and SCaN (Space Communications and Navigation) Program manager at NASA Headquarters in Washington. “As we seek to extend humanity beyond our home planet, LuGRE should confirm that this extraordinary technology can do the same for us on the Moon.”
NASA, Firefly, Qascom, and Italian Space Agency team members examine LuGRE hardware in a clean room.Firefly Aerospace Reliable space communication and navigation systems play a vital role in all NASA missions, providing crucial connections from space to Earth for crewed and uncrewed missions alike. Using a blend of government and commercial assets, NASA’s Near Space and Deep Space Networks support science, technology demonstrations, and human spaceflight missions across the solar system.
“This mission is more than a technological milestone,” said Joel Parker, policy lead for positioning, navigation, and timing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We want to enable more and better missions to the Moon for the benefit of everyone, and we want to do it together with our international partners.”

JOEL PARKER
PNT Policy Lead at NASA's Goddard Space Flight Center
The data-gathering LuGRE payload combines NASA-led systems engineering and mission management with receiver software and hardware developed by the Italian Space Agency and their industry partner Qascom — the first Italian-built hardware to operate on the lunar surface.
Any data LuGRE collects is intended to open the door for use of GNSS to all lunar missions, not just those by NASA or the Italian Space Agency. Approximately six months after LuGRE completes its operations, the agencies will release its mission data to broaden public and commercial access to lunar GNSS research.
Firefly Aerospace’s Blue Ghost Mission One lander is carrying 10 NASA science and technology instruments to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.Firefly Aerospace “A project like LuGRE isn’t about NASA alone,” said NASA Goddard navigation and mission design engineer Lauren Konitzer. “It’s something we’re doing for the benefit of humanity. We’re working to prove that lunar GNSS can work, and we’re sharing our discoveries with the world.”
The LuGRE payload is one of 10 NASA-funded science experiments launching to the lunar surface on this delivery through NASA’s CLPS initiative. Through CLPS, NASA works with American companies to provide delivery and quantity contracts for commercial deliveries to further lunar exploration and the development of a sustainable lunar economy. As of 2024, the agency has 14 private partners on contract for current and future CLPS missions.
Demonstrations like LuGRE could lay the groundwork for GNSS-based navigation systems on the lunar surface. Bridging these existing systems with emerging lunar-specific navigation solutions has the potential to define how all spacecraft navigate lunar terrain in the Artemis era.

Funding and oversight for the LuGRE payload comes from the agency’s SCaN Program office. It was chosen by NASA as one of 10 funded research and technology demonstrations for delivery to the lunar surface by Firefly Aerospace Inc, a flight under the agency’s CLPS initiative.

Este mapa de la Tierra en 2024 muestra las anomalías de la temperatura global de la superficie, es decir, cuánto más caliente o más fría estuvo cada región del planeta en comparación con el promedio de 1951 a 1980. Las temperaturas normales se muestran en blanco, las superiores a las normales en rojo y naranja, y las inferiores a las normales en azul. Una versión animada de este mapa muestra la evolución de las anomalías de la temperatura global a lo largo del tiempo, desde 1880. Descarga esta visualización del Estudio de Visualización Científica del Centro Goddard de la NASA: https://svs.gsfc.nasa.gov/5450.Crédito: Estudio de Visualización Científica de la NASA Read this release in English here.
En el año 2024, la temperatura promedio de la superficie de la Tierra fue la más cálida que se haya registrado, según un análisis liderado por científicos de la NASA.
“Una vez más, se ha batido el récord de temperatura: 2024 fue el año más cálido desde que se empezaron a llevar registros en 1880”, dijo el administrador de la NASA, Bill Nelson. “Entre las temperaturas récord y los incendios forestales que amenazan actualmente nuestros centros y personal en California, nunca ha sido más importante entender nuestro planeta cambiante”.
Las temperaturas globales del 2024 estuvieron 2,30 grados Fahrenheit (1,28 grados Celsius) por encima del promedio para el período de referencia de la NASA (de 1951 a 1980), superando el récord establecido en 2023. El nuevo máximo histórico llega después de 15 meses consecutivos (junio de 2023 a agosto de 2024) de récords de temperaturas mensuales, una racha de calor sin precedentes.
Científicos de la NASA también estiman que en el 2024 la Tierra estuvo alrededor de 2,65 grados Fahrenheit (1,47 grados Celsius) más cálida que el promedio de mediados del siglo XIX (1850-1900). Durante más de la mitad del 2024, las temperaturas promedio superaron en 1,5 grados Celsius el nivel de referencia, y el promedio anual, con incertidumbres matemáticas, podría haber superado el nivel por primera vez.
“El Acuerdo de París sobre el cambio climático establece esfuerzos para mantenerse por debajo del nivel de 1,5 grados a largo plazo. Para poner eso en perspectiva, las temperaturas durante los períodos cálidos en la Tierra hace tres millones de años —cuando el nivel del mar era decenas de metros más alto que hoy— eran solo unos 3 grados Celsius más cálidos que los niveles preindustriales”, dijo Gavin Schmidt, director del Instituto Goddard de Investigaciones Espaciales (GISS, por sus siglas en inglés) de la NASA en Nueva York. “Estamos a medio camino de alcanzar niveles de calor del Plioceno en apenas 150 años”.
Los científicos han concluido que la tendencia al calentamiento de las últimas décadas está siendo impulsada por el dióxido de carbono, el metano y otros gases de efecto invernadero que atrapan el calor. Según un análisis internacional reciente, en 2022 y 2023 la Tierra registró un aumento récord de las emisiones de dióxido de carbono procedentes de combustibles fósiles. La concentración de dióxido de carbono en la atmósfera ha aumentado desde los niveles preindustriales en el siglo XVIII de aproximadamente 278 partes por millón a alrededor de 420 partes por millón en la actualidad.
La NASA y otras agencias federales recopilan regularmente datos sobre las concentraciones y emisiones de gases de efecto invernadero. Estos datos están disponibles en el Centro de Gases de Efecto Invernadero de Estados Unidos, una iniciativa de múltiples instituciones que consolida la información procedente de observaciones y modelos, con el fin de ofrecer a los responsables de la toma de decisiones un único punto de acceso a datos y análisis.
Tendencias de calor excepcional
Las temperaturas de cada año pueden verse influidas por fluctuaciones climáticas naturales como El Niño y La Niña, que alternativamente calientan y enfrían el océano Pacífico tropical. El fuerte fenómeno de El Niño que comenzó en el otoño boreal de 2023 contribuyó a que las temperaturas mundiales superaran los récords anteriores.
La ola de calor que comenzó en 2023 siguió superando las expectativas en 2024, según Schmidt, a pesar de que El Niño remitió. Los investigadores están trabajando en la identificación de los factores que contribuyen a este fenómeno, incluidos los posibles efectos climáticos de la erupción volcánica de Tonga de enero de 2022 y de las reducciones de la contaminación, que pueden cambiar la cubierta de nubes y la forma en que la energía solar se refleja hacia el espacio.
“No en todos los años se van a batir récords, pero la tendencia a largo plazo es clara”, dijo Schmidt. “Ya estamos viendo el impacto en las precipitaciones extremas, las olas de calor y el aumento del riesgo de inundaciones, que van a seguir empeorando mientras continúen las emisiones”.
Cambios a nivel local
La NASA elabora su registro de temperaturas a partir de los datos de temperatura del aire en superficie recolectados por decenas de miles de estaciones meteorológicas, así como de los datos de temperatura de la superficie del mar adquiridos por instrumentos en barcos y boyas. Para el análisis de estos datos, se emplean métodos que toman en consideración el espaciamiento variado de las estaciones de temperatura a nivel global y los efectos del calentamiento urbano que podrían sesgar los cálculos.
Una nueva evaluación publicada a principios de este año por científicos de la Escuela de Minas de Colorado, la Fundación Nacional para las Ciencias, la Administración Nacional Oceánica y Atmosférica (NOAA, por sus siglas en inglés) y la NASA provee aún más confianza en los datos de temperatura global y regional de la agencia.
“Cuando se producen cambios en el clima, primero se ven en la media mundial, luego se ven a nivel continental y después a nivel regional. Ahora lo estamos viendo a nivel local”, dijo Schmidt. “Los cambios que se están produciendo en las experiencias meteorológicas cotidianas de la gente se han hecho muy evidentes”.
Los análisis independientes de la NOAA, Berkeley Earth, el Centro Hadley (parte de la Oficina Meteorológica del Reino Unido, Met Office) y el Servicio de Cambio Climático de Copernicus en Europa también han concluido que las temperaturas de la superficie global para 2024 fueron las más altas desde que comenzaron los registros modernos. Estos científicos utilizan gran parte de los mismos datos de temperatura en sus análisis, pero emplean metodologías y modelos diferentes. Todos muestran la misma tendencia al calentamiento.
El conjunto completo de datos de la NASA sobre las temperaturas de la superficie global, así como los detalles (en inglés) de cómo los científicos de la NASA llevaron a cabo el análisis, están a disposición del público en GISS, un laboratorio de la NASA gestionado por el Centro de Vuelo Espacial Goddard de la agencia en Greenbelt, Maryland.
