Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Compact Fire Infrared Radiance Spectral tracker, or C-FIRST, is managed an operated by NASA’s Jet Propulsion Laboratory, and supported by NASA’s Earth Science Technology Office. Combining state-of-the-art imaging technology with a compact design, C-FIRST enables scientists to gather data about fires and their impacts on ecosystems with greater accuracy and speed than other instruments. C-FIRST was developed as a spaceborne instrument, and flew onboard NASA’s B200 aircraft in January 2025 to conduct an airborne test.NASA/JPL-Caltech The January wildfires in California devastated local habitats and communities. In an effort to better understand wildfire behavior, NASA scientists and engineers tried to learn from the events by testing new technology.
The new instrument, the Compact Fire Infrared Radiance Spectral Tracker (c-FIRST), was tested when NASA’s B200 King Air aircraft flew over the wildfires in the Pacific Palisades and Altadena, California. Based at NASA’s Armstrong Flight Research Center in Edwards, California, the aircraft used the c-FIRST instrument to observe the impacts of the fires in near real-time. Due to its small size and ability to efficiently simulate a satellite-based mission, the B200 King Air is uniquely suited for testing c-FIRST.
Managed and operated by NASA’s Jet Propulsion Laboratory in Southern California, c-FIRST gathers thermal infrared images in high-resolution and other data about the terrain to study the impacts of wildfires on ecology. In a single observation, c-FIRST can capture the full temperature range across a wide area of wildland fires – as well as the cool, unburned background – potentially increasing both the quantity and quality of science data produced.
“Currently, no instrument is able to cover the entire range of attributes for fires present in the Earth system,” said Sarath Gunapala, principal investigator for c-FIRST at NASA JPL. “This leads to gaps in our understanding of how many fires occur, and of crucial characteristics like size and temperature.”
For decades, the quality of infrared images has struggled to convey the nuances of high-temperature surfaces above 1,000 degrees Fahrenheit (550 degrees Celsius). Blurry resolution and light saturation of infrared images has inhibited scientists’ understanding of an extremely hot terrain, and thereby also inhibited wildfire research. Historically, images of extremely hot targets often lacked the detail scientists need to understand the range of a fire’s impacts on an ecosystem.
NASA’s Armstrong Flight Research Center in Edwards, California, flew the B200 King Air in support of the Signals of Opportunity Synthetic Aperture Radar (SoOpSAR) campaign on Feb. 27, 2023.NASA/Steve Freeman To address this, NASA’s Earth Science Technology Office supported JPL’s development of the c-FIRST instrument, combining state-of-the-art imaging technology with a compact and efficient design. When c-FIRST was airborne, scientists could detect smoldering fires more accurately and quickly, while also gathering important information on active fires in near real-time.
“These smoldering fires can flame up if the wind picks up again,” said Gunapala. “Therefore, the c-FIRST data set could provide very important information for firefighting agencies to fight fires more effectively.”
For instance, c-FIRST data can help scientists estimate the likelihood of a fire spreading in a certain landscape, allowing officials to more effectively monitor smoldering fires and track how fires evolve. Furthermore, c-FIRST can collect detailed data that can enable scientists to understand how an ecosystem may recover from fire events.
“The requirements of the c-FIRST instrument meet the flight profile of the King Air,” said KC Sujan, operations engineer for the B200 King Air. “The c-FIRST team wanted a quick integration, the flight speed in the range 130 and 140 knots on a level flight, communication and navigation systems, and the instruments power requirement that are perfectly fit for King Air’s capability.”
By first testing the instrument onboard the B200 King Air, the c-FIRST team can evaluate its readiness for future satellite missions investigating wildfires. On a changing planet where wildfires are increasingly common, instruments like c-FIRST could provide data that can aid firefighting agencies to fight fires more effectively, and to understand the ecosystemic impacts of extreme weather events.

The cover of Spinoff 2025, NASA’s annual publication that chronicles commercial products born from space technology, is a detailed view of the lunar surface captured by cameras on the Orion spacecraft on a close approach of the Moon during the Artemis I mission.Credit: NASA The latest edition of NASA’s Spinoff publication, which highlights the successful transfer of agency technology to the commercial sector, is now available online.
For nearly 25 years, NASA has supported crew working in low Earth orbit to learn about the space environment and perform research to advance deep space exploration. Astronauts aboard the International Space Station have learned a wealth of lessons and tried out a host of new technologies. This work leads to ongoing innovations benefiting people on Earth that are featured in NASA’s annual publication.
“The work we do in space has resulted in navigational technologies, lifesaving medical advancements, and enhanced software systems that continue to benefit our lives on Earth,” said Clayton Turner, associate administrator, Space Technology Mission Directorate at NASA Headquarters in Washington. “Technologies developed today don’t just make life on our home planet easier – they pave the way to a sustained presence on the Moon and future missions to Mars.”
The Spinoff 2025 publication features more than 40 commercial infusions of NASA technologies including:
A platform enabling commercial industry to perform science on the space station, including the growth of higher-quality human heart tissue, knee cartilage, and pharmaceutical crystals that can be grown on Earth to develop new medical treatments. An electrostatic sprayer technology to water plants without the help of gravity and now used in sanitation, agriculture, and food safety. “Antigravity” treadmills helping people with a variety of conditions run or walk for exercise, stemming from efforts to improve astronauts’ fitness in the weightlessness of space. Nutritional supplements originally intended to keep astronauts fit and mitigate the health hazards of a long stay in space. As NASA continues advancing technology and research in low Earth orbit to establish a sustained presence at the Moon, upcoming lunar missions are already spinning off technologies on Earth. For example, Spinoff 2025 features a company that invented technology for 3D printing buildings on the Moon that is now using it to print large structures on Earth. Another group of researchers studying how to grow lunar buildings from fungus is now selling specially grown mushrooms and plans to build homes on Earth using the same concept.
Spinoffs produce innovative technologies with commercial applications for the benefit of all. Other highlights of Spinoff 2025 include quality control on assembly lines inspired by artificial intelligence developed to help rovers navigate Mars, innovations in origami based on math for lasers and optical computing, and companies that will help lead the way to hydrogen-based energy building on NASA’s foundation of using liquid hydrogen for rocket fuel.
“I’ve learned it’s almost impossible to predict where space technology will find an application in the commercial market,” said Dan Lockney, Technology Transfer program executive at NASA Headquarters in Washington. “One thing I can say for sure, though, is NASA’s technology will continue to spin off, because it’s our goal to advance our missions and bolster the American economy.”
This publication also features 20 technologies available for licensing with the potential for commercialization. Check out the “Spinoffs of Tomorrow” section to learn more.
Spinoff is part of NASA’s Space Technology Mission Directorate and its Technology Transfer program.

During a live Fox News broadcast covering the intense Palisades wildfire in California, an unusual event captured viewers' attention. A camera aimed at the blazing inferno recorded a mysterious spherical object emerging suddenly from the middle of the flames. This object moved at a remarkable speed before vanishing over the treetops, leaving many wondering about its origin and purpose.
The object does not appear to be debris carried aloft by the fire’s updraft. Its trajectory and speed seem too controlled and deliberate to be a random effect of the wildfire. Additionally, the object shows no signs of explosion or disintegration, characteristics that might be expected if it were merely a piece of material affected by the intense heat.
Observers have ruled out common explanations such as birds, planes, or helicopters. The object’s rapid movement and apparent change in direction suggest advanced maneuverability, sparking comparisons to UFOs/UAPs.
With the growing number of reported sightings involving drones, orbs, and UFOs, the appearance of this potential UFO or drone in such an environment is especially intriguing. Could this object represent evidence of advanced technology monitoring Earth's natural disasters? Or is it an entirely natural but poorly understood phenomenon?

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping scientists understand Io’s interior. Image data: NASA/JPL-Caltech/SwRI/MSSS
Image processing by Gerald Eichstädt A new study points to why, and how, Io became the most volcanic body in the solar system.
Scientists with NASA’s Juno mission to Jupiter have discovered that the volcanoes on Jupiter’s moon Io are each likely powered by their own chamber of roiling hot magma rather than an ocean of magma. The finding solves a 44-year-old mystery about the subsurface origins of the moon’s most demonstrative geologic features.
A paper on the source of Io’s volcanism was published on Thursday, Dec. 12, in the journal Nature, and the findings, as well as other Io science results, were discussed during a media briefing in Washington at the American Geophysical Union’s annual meeting, the country’s largest gathering of Earth and space scientists.
About the size of Earth’s Moon, Io is known as the most volcanically active body in our solar system. The moon is home to an estimated 400 volcanoes, which blast lava and plumes in seemingly continuous eruptions that contribute to the coating on its surface.
This animated tour of Jupiter’s fiery moon Io, based on data collected by NASA’s Juno mission, shows volcanic plumes, a view of lava on the surface, and the moon’s internal structure. NASA/JPL-Caltech/SwRI/Koji Kuramura/Gerald Eichstädt Although the moon was discovered by Galileo Galilei on Jan. 8, 1610, volcanic activity there wasn’t discovered until 1979, when imaging scientist Linda Morabito of NASA’s Jet Propulsion Laboratory in Southern California first identified a volcanic plume in an image from the agency’s Voyager 1 spacecraft.
“Since Morabito’s discovery, planetary scientists have wondered how the volcanoes were fed from the lava underneath the surface,” said Scott Bolton, Juno principal investigator from the Southwest Research Institute in San Antonio. “Was there a shallow ocean of white-hot magma fueling the volcanoes, or was their source more localized? We knew data from Juno’s two very close flybys could give us some insights on how this tortured moon actually worked.”
The Juno spacecraft made extremely close flybys of Io in December 2023 and February 2024, getting within about 930 miles (1,500 kilometers) of its pizza-faced surface. During the close approaches, Juno communicated with NASA’s Deep Space Network, acquiring high-precision, dual-frequency Doppler data, which was used to measure Io’s gravity by tracking how it affected the spacecraft’s acceleration. What the mission learned about the moon’s gravity from those flybys led to the new paper by revealing more details about the effects of a phenomenon called tidal flexing.
This five-frame sequence shows a giant plume erupting from Io’s Tvashtar volcano, extending 200 miles (330 kilometers) above the fiery moon’s surface. It was captured over an eight-minute period by NASA’s New Horizons mission as the spacecraft flew by Jupiter in 2007.NASA/Johns Hopkins APL/SwRI Prince of Jovian Tides
Io is extremely close to mammoth Jupiter, and its elliptical orbit whips it around the gas giant once every 42.5 hours. As the distance varies, so does Jupiter’s gravitational pull, which leads to the moon being relentlessly squeezed. The result: an extreme case of tidal flexing — friction from tidal forces that generates internal heat.
“This constant flexing creates immense energy, which literally melts portions of Io’s interior,” said Bolton. “If Io has a global magma ocean, we knew the signature of its tidal deformation would be much larger than a more rigid, mostly solid interior. Thus, depending on the results from Juno’s probing of Io’s gravity field, we would be able to tell if a global magma ocean was hiding beneath its surface.”
The Juno team compared Doppler data from their two flybys with observations from the agency’s previous missions to the Jovian system and from ground telescopes. They found tidal deformation consistent with Io not having a shallow global magma ocean.
“Juno’s discovery that tidal forces do not always create global magma oceans does more than prompt us to rethink what we know about Io’s interior,” said lead author Ryan Park, a Juno co-investigator and supervisor of the Solar System Dynamics Group at JPL. “It has implications for our understanding of other moons, such as Enceladus and Europa, and even exoplanets and super-Earths. Our new findings provide an opportunity to rethink what we know about planetary formation and evolution.”
There’s more science on the horizon. The spacecraft made its 66th science flyby over Jupiter’s mysterious cloud tops on Nov. 24. Its next close approach to the gas giant will occur 12:22 a.m. EST, Dec. 27. At the time of perijove, when Juno’s orbit is closest to the planet’s center, the spacecraft will be about 2,175 miles (3,500 kilometers) above Jupiter’s cloud tops and will have logged 645.7 million miles (1.039 billion kilometers) since entering the gas giant’s orbit in 2016.
