Preparations for Next Moonwalk Simulations Underway (and Underwater)
Jacquelyn Shuman visually assesses a prescribed fire at Ft. Stewart in Georgia, working with partner organizations as part of the Department of Defense Ft. Stewart 2024 Fire Research Campaign. USFS/Linda Chappell Jacquelyn Shuman, FireSense Project Scientist at NASA Ames Research Center, originally wanted to be a veterinarian. By the time she got to college, Shuman had switched interests to biology, which became a job teaching middle and high school science. Teaching pivoted to finance for a year, before Shuman returned to the science world to pursue a PhD.
It was in a forest ecology class taught by her future PhD advisor, Herman “Hank” Shugart, that she first discovered a passion for ecosystems and dynamic vegetation that led her into the world of fire science, and eventually to NASA Ames.
While Shuman’s path into the world of fire science was not a direct one, she views her diverse experiences as the key to finding a fulfilling career. “Do a lot of different things and try a lot of different things, and if one thing isn’t connecting with you, then do something different,” Shuman said.
Diving into the World of Fire
Shuman’s PhD program focused on boreal forest dynamics across Russia, examining how the forest changes in response to climate change and wildfire. During her research, she worked mainly with scientists from Russia, Canada, and the US through the Northern Eurasia Earth Science Partnership Initiative (NEESPI), where Shugart served as the NEESPI Chief Scientist. “The experience of having a highly supportive mentor, being a part of the NEESPI community, and working alongside other inspiring female scientists from across the globe helped me to stay motivated within my own research,” Shuman said.
After completing her PhD, Shuman wanted to become involved in collaborative science with a global impact, which led her to the National Center for Atmospheric Research (NCAR). There, she spent seven years working as a project scientist on the Next Generation Ecosystem Experiment NGEE-Tropics) on a dynamic vegetation model project called FATES (Functionally Assembled Terrestrial Ecosystem Simulator). As part of the FATES team, Shuman used computer modeling to test vegetation structure and function in tropical and boreal forests after wildfires, and was the lead developer for updating the fire portion of the model.
This figure shows fire characteristics from an Earth system model that uses vegetation structure and interactive fire. The FATES model captures the fire intensity associated with burned land and grass growth in the Southern Hemisphere. Shuman et al. 2024 GMD Fire has also played a powerful role in Shuman’s personal life. In 2021, the Marshall Fire destroyed neighborhoods near her hometown of Boulder, Colorado, causing over $513 million of damage and securing its place as the state’s most destructive wildfire. Despite this, Shuman is determined to not live in fear. “Fire is part of our lives, it’s a part of the Earth system, and it’s something we can plan for. We can live more sustainably with fires.” The way to live safely in a fire-inclusive ecosystem, according to Shuman, is to develop ways to accurately track and forecast wildfires and smoke, and to respond to them efficiently: efforts the fire community is continuously working on improving.
The Fire Science Community
Collaboration is a critical element of wildland fire management. Fire science is a field that involves practitioners such as firefighters and land managers, but also researchers such as modelers and forecasters; the most effective efforts, according to Shuman, come when this community works together. “People in fire science might be out in the field and carrying a drip torch and marching along in the hilltops and the grasslands or be behind a computer and analyzing remote sensing data,” Shuman said. “We need both pieces.”
Protecting communities from wildfire impacts is one of the most fulfilling aspects of Shuman’s career, and a goal that unites this community. “Fire research poses tough questions, but the people who are thinking about this are the people who are acting on it,” Shuman said. “They are saying, ‘What can we do? How can we think about this? What information do we need? What are the questions?’ It’s a special community to be a part of.”
Looking to the Future of Fire
Currently at NASA Ames Research Center, Shuman is the Project Scientist for FireSense: a project focused on delivering NASA science and technology to practitioners and operational agencies. Shuman acts as the lead for the project office, identifying and implementing tools and strategies. Shuman still does ecosystem modeling work, including implementing vegetation models that forecast the impact of fire, but also spends time traveling to active fires across the country so she can help partners implement NASA tools and strategies in real time.

“Right now, many different communities are all recognizing that we can partner to identify the best path forward,” Shuman said. “We have an opportunity to use everyone’s strengths and unique perspectives. It can be a devastating thing for a community and an ecosystem when a fire happens. Everyone is interested in using all this collective knowledge to do more, together.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
A SpaceX Falcon Heavy rocket with the Europa Clipper spacecraft aboard is seen at Launch Complex 39A as preparations continue for the mission, Sunday, Oct. 13, at NASA’s Kennedy Space Center in Florida. NASA Find details about the launch sequences for the orbiter, which is targeting an Oct. 14 liftoff on its mission to search for ingredients of life at Jupiter’s moon Europa.
In less than 24 hours, NASA’s Europa Clipper spacecraft is slated to launch from the agency’s Kennedy Space Center in Florida aboard a Falcon Heavy rocket. Its sights are set on Jupiter’s ice-encased moon Europa, which the spacecraft will fly by 49 times, coming as close as 16 miles (25 kilometers) from the surface as it searches for ingredients of life.
Launch is set for 12:06 p.m. EDT on Monday, Oct. 14, with additional opportunities through Nov 6. Each opportunity is instantaneous, meaning there is only one exact time per day when launch can occur. Plans to launch Europa Clipper on Oct. 10 were delayed due to impacts of Hurricane Milton.
NASA’s Europa Clipper is the first mission dedicated to studying Jupiter’s icy moon Europa, one of the most promising places in our solar system to find an environment suitable for life outside of Earth. With its massive solar arrays extended, Europa Clipper could span a basketball court (100 feet, or 30.5 meters, tip to tip). In fact, it’s the largest spacecraft NASA has ever built for a planetary mission. The journey to Jupiter is a long one — 1.8 billion miles (2.9 billion kilometers) — and rather than taking a straight path there, Europa Clipper will loop around Mars and then Earth, gaining speed as it swings past.
The spacecraft will begin orbiting Jupiter in April 2030, and in 2031 it will start making those 49 science-focused flybys of Europa while looping around the gas giant. The orbit is designed to maximize the science Europa Clipper can conduct and minimize exposure to Jupiter’s notoriously intense radiation.
But, of course, before any of that can happen, the spacecraft has to leave Earth behind. The orbiter’s solar arrays are folded and stowed for launch. Testing is complete on the spacecraft’s various systems and its payload of nine science instruments and a gravity science investigation. Loaded with over 6,060 pounds (2,750 kilograms) of the propellant that will get Europa Clipper to Jupiter, the spacecraft has been encapsulated in the protective nose cone, or payload fairing, atop a SpaceX Falcon Heavy rocket, which is poised for takeoff from historic Launch Complex 39A.
Launch Sequences
The Falcon Heavy has two stages and two side boosters. After the side boosters separate, the core stage will be expended into the Atlantic Ocean. Then the second stage of the rocket, which will help Europa Clipper escape Earth’s gravity, will fire its engine.
Technicians encapsulated NASA’s Europa Clipper spacecraft inside payload fairings on Wednesday, Oct. 2, at NASA’s Kennedy Space Center in Florida. The fairings will protect the spacecraft during launch as it begins its journey to explore Jupiter’s icy moon Europa. NASA/Ben Smegelsky Once the rocket is out of Earth’s atmosphere, about 50 minutes after launch, the payload fairing will separate from its ride, split into two halves, and fall safely back to Earth, where it will be recovered and reused. The spacecraft will then separate from the upper stage about an hour after launch. Stable communication with the spacecraft is expected by about 19 minutes after separation from the rocket, but it could take somewhat longer.
About three hours after launch, Europa Clipper will deploy its pair of massive solar arrays, one at a time, and direct them at the Sun.
Mission controllers will then begin to reconfigure the spacecraft into its planned operating mode. The ensuing three months of initial checkout include a commissioning phase to confirm that all hardware and software is operating as expected.
While Europa Clipper is not a life-detection mission, it will tell us whether Europa is a promising place to pursue an answer to the fundamental question about our solar system and beyond: Are we alone?
Scientists suspect that the ingredients for life — water, chemistry, and energy — could exist at the moon Europa right now. Previous missions have found strong evidence of an ocean beneath the moon’s thick icy crust, potentially with twice as much liquid water as all of Earth’s oceans combined. Europa may be home to organic compounds, which are essential chemical building blocks for life. Europa Clipper will help scientists confirm whether organics are there, and also help them look for evidence of energy sources under the moon’s surface.

Scheduled to arrive at Jupiter in April 2030, the mission will be the first to specifically target Europa for detailed science investigation. NASA/JPL-Caltech More About Europa Clipper
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland; NASA’s Marshall Space Flight Center in Huntsville, Alabama; and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

Back to Fire Science Landing Page FireSense
The FireSense project is focused on delivering NASA’s unique Earth science and technological capabilities to operational agencies, striving to address challenges in US wildland fire management. The project concentrates on four use-cases to support decisions before, during, and after wildland fires. These include the measurement of pre-fire fuels conditions, active fire dynamics, post fire impacts and threats, as well as air quality forecasting, each co-developed with identified wildland fire management agency stakeholders.
Strategic Tac Radio and Tac Overwatch (STRATO)
The Strategic Tac Radio and Tac Overwatch (STRATO) system is designed to provide real-time fire observations and last-mile communications with firefighters from stratospheric platforms. By providing persistent communications to a wildfire response team for a week or longer, STRATO is expected to offer capabilities beyond the currently used tethered balloons, which have a limited range and coverage area. By achieving station-keeping at altitudes up to 70,000 feet above ground level—to be demonstrated in flight testing—the STRATO will be able to provide communications to incident response teams in areas with no cellphone coverage.
