NASA and the Federal Aviation Administration (FAA) have established a research transition team to guide the development of wildland fire technology. 

Wildland fires are occurring more frequently and at a larger scale than in past decades, according to the U.S. Forest Service. Emergency responders will need a broader set of technologies to prevent, monitor, and fight these growing fires more effectively. Under this Wildland Fire Airspace Operations research transition team, NASA and the FAA will develop concepts and test new technologies to improve airspace integration. 

Current aerial firefighting operations are limited to times when aircraft have clear visibility – otherwise pilots run the risk of flying into terrain or colliding with other aircraft. Drones could overcome this limitation by enabling responders to remotely monitor and suppress these fires during nighttime and low visibility conditions, such as periods of heavy smoke. However, advanced airspace management technologies are needed to enable these uncrewed aircraft to stay safely separated and allow aircraft operators to maintain situational awareness during wildland fire management response operations. 

Over the next four years, NASA’s Advanced Capabilities for Emergency Response Operations (ACERO) project, in collaboration with the FAA, will work to develop new airspace access and traffic management concepts and technologies to support wildland fire operations. These advancements will help inform a concept of operations for the future of wildland fire management under development by NASA and other government agencies. The team will test and validate uncrewed aircraft technologies for use by commercial industry and government agencies, paving the way for integrating them into future wildland fire operations.  

ACERO is led out of NASA’s Ames Research Center in Silicon Valley under the agency’s Aeronautics Research Mission Directorate.

Join NASA in Celebrating Earth Day 2024 by Sharing a #GlobalSelfie

The globe of the Earth is visible against a black background. Overlaid in white lettering is "#GlobalSelfie."

NASA invites you — and everyone else on the planet — to take part in a worldwide celebration of Earth Day with the agency’s #GlobalSelfie event. While NASA satellites constantly look at Earth from space, on Earth Day we’re asking you to step outside and take a picture of yourself in your corner of the world. Then post it to social media using the hashtag #GlobalSelfie.

Bonus points if your #GlobalSelfie features your favorite body of water! About 71% of our Blue Marble is covered by water, and that water is one of the main reasons why Earth is like no other planet we’ve found in this solar system, or beyond.

Why #GlobalSelfie?

NASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. With Earth-observing missions orbiting our home planet right now, and more set to launch this year, NASA studies Earth’s atmosphere, land and oceans in all their complexity.

For Earth Day, we want everyone to share the planet from their point of view. Need an idea of what kind of picture to take? Get outside and show us mountains, parks, the sky, rivers, lakes – and you! Wherever you are, there’s your picture. 

How do I take part?

Post your photo to social media using the hashtag #GlobalSelfie. Make it public so we can see, and celebrate #EarthDay with you!

NASA Selects New Aircraft-Driven Studies of Earth and Climate Change

NASA has selected six new airborne missions that include domestic and international studies of fire-induced clouds, Arctic coastal change, air quality, landslide hazards, shrinking glaciers, and emissions from agricultural lands. NASA’s suite of airborne missions complement what scientists can see from orbit, measure from the ground, and simulate in computer models.  

Funded through the agency’s Earth Venture program, the missions center around the use of instruments mounted on aircraft to make measurements in finer detail—both in spatial resolution and shorter time scales—than can be made by many satellites. Competitively selected, the missions provide opportunities to supplement satellite observations and make innovative measurements.

“These missions will help us interpret what our current satellites are seeing from space and test new ideas and techniques for our upcoming Earth System Observatory,” said Karen St. Germain, director of NASA’s Earth Science Division. “There is also a strong focus on actionable Earth science—gathering fundamental observations that have connections to our economy and societal decision-making and information needs.”

Roughly $120 million has been allotted for the six missions, which will deploy at various times from 2026 to 2029. Three lead investigators were chosen for each mission, with at least one required to be an early career scientist. Full staffing of the science teams and selection of complementary instruments will be competed in the coming months. These changes in the selection process were made to promote diversity, equity, and inclusion in the teams.  

“We are constantly looking to foster the growth of the next generation of scientists,” said Barry Lefer, the program manager who led the Earth Venture selection panels at NASA Headquarters in Washington. “This round of missions will put an extra emphasis on bringing new people into mission planning and leadership.”

The six missions include:

Arctic coastal change

Maria Tzortziou of the City College of New York will lead a project to observe changes in river systems on the North Slope of Alaska. Known as FORTE (short for Arctic Coastlines–The Frontlines of Rapidly Transforming Ecosystems), the project will combine optical and radar measurements from planes, helicopters, boats, and drones to measure water flows and chemistry and observe how ecosystems respond to changing climate. The team will collaborate with indigenous communities to sustain observations over time.

Clouds created by fire

In PYREX—the Pyrocumulonimbus Experiment—David Peterson of the Naval Research Laboratory in Washington will lead a study of pyrocumulonimbus clouds, which form when wildfires burn hot enough to make their own weather. Flying over the western U.S. and Canada, researchers will examine the fire characteristics that produce pyrocumulonimbus, while exploring the mechanisms that lead these clouds to inject smoke into the stratosphere, where it can have climate effects.

Urban air pollution

James Crawford of NASA’s Langley Research Center in Hampton, Virginia, will lead HAMAQ (Hemispheric Airborne Measurements of Air Quality), a project that capitalizes on the recent launches of NASA’s TEMPO pollution-monitoring satellite instrument and comparable measurements made by Korean and European satellites. Over Mexico City and a U.S. city to be determined, scientists will investigate areas of poor air quality and test how satellite information can help improve ground-based forecasting and mitigation strategies.

Shifting weather, shifting lands

Climate change is leading to more extreme droughts and rainfall events that affect the stability of hillslopes and the soil and rock on them. Led by Alexander Handwerger of NASA’s Jet Propulsion Laboratory in Pasadena, California, LACCE (Landslide Climate Change Experiment) will combine airborne measurements with land-based sensors to track the way slopes and landslides are changing as water moves differently across the landscape.

Glacier retreat

John Holt of the University of Arizona will lead Snow4Flow, a project to quantify the retreat of glaciers and ice sheets in ways that can lead to better projections of land-ice change. In Alaska, southeastern Greenland, the Canadian Arctic, and Svalbard, the team will use microwave and high-frequency radar sounders to measure snow accumulation, ice melting, and changes in ice thickness and motion.

Agricultural emissions

While the burning of fossil fuels remains the leading source of carbon in our atmosphere, farmlands and ranchlands are also substantial sources of gas and particle emissions. In the NTERFAACE (Nitrogen and Carbon Terrestrial Fluxes: Agriculture, Atmospheric Composition, and Ecosystems) mission, led by Glenn Wolfe of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, researchers will measure the amount of greenhouse gases, nitrogen, and other pollutants that are emitted from agricultural lands across the United States.

The PYREX and Snow4Flow missions are funded at $30 million each, while the other four projects will each receive $15 million. These six investigations were selected from 42 proposals. The 2024 selections represent the fourth series of NASA Earth Venture investigations, which were first recommended by the National Research Council in 2007.

Hubble Captures a Bright Galactic and Stellar Duo

A spiral galaxy, seen face-on to the viewer. The bright center of the galaxy is crossed by a glowing bar, and it is surrounded by tightly wound spiral arms, forming a circular shape with relatively clear edges. Faraway galaxies are visible around it, along with a few bright stars, on a dark background. One star to the right of the galaxy is very large and extremely bright with long diffraction spikes.
This image from the NASA/ESA Hubble Space Telescope features the barred spiral galaxy NGC 3783.

This image from the NASA/ESA Hubble Space Telescope features NGC 3783, a bright barred spiral galaxy about 130 million light-years from Earth that also lends its name to the eponymous NGC 3783 galaxy group. Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than galaxy clusters do: whereas galaxy clusters can contain hundreds or even thousands of constituent galaxies, galaxy groups do not typically include more than 50. The Milky Way is actually part of a galaxy group, known as the Local Group, which also holds two other large galaxies (Andromeda and the Triangulum galaxy), as well as several dozen satellite and dwarf galaxies. The NGC 3783 galaxy group contains 47 galaxies. It also seems to be at a fairly early stage of its evolution, making it an interesting object to study. 

While the focus of this image is the spiral galaxy NGC 3783, the eye is equally drawn to the very bright object in the lower right part of this image. This is the star HD 101274. The perspective in this image makes the star and the galaxy look like close companions, but this is an illusion. HD 101274 lies only about 1,530 light-years from Earth, it is about 85,000 times closer than NGC 3783. This explains how a single star can appear to outshine an entire galaxy! 

NGC 3783 is a type-1 Seyfert galaxy, which is a galaxy with a bright central region. Hubble captures it in incredible detail, from its glowing central bar to its narrow, winding arms and the dust threaded through them, thanks to five separate images taken in different wavelengths of light. In fact, the galactic center is so bright that it exhibits diffraction spikes, normally only seen on stars such as HD 101274.

Students Celebrate Rockets, Environment at NASA’s Kennedy Space Center

Students Celebrate Rockets, Environment at NASA’s Kennedy Space Center

Students from Andrew Jackson Middle School in Titusville, Florida, participate in an environmentally focused Earth Day briefing on Tuesday, April 2, 2024, inside the news auditorium at the agency’s Kennedy Space Center in Florida. The panelists from left to right are Messod Bendayan, NASA Communications; Kelly McCarthy, NASA’s Office of STEM Engagement, Bob Kline, Kennedy’s Environmental Assurance Branch; Spencer Davis, Kennedy’s Exploration Ground Systems; Kim King-Wrenn, Merritt Island National Wildlife Refuge.

At NASA’s Kennedy Space Center, sustainability and preservation efforts here on Earth are as much of a priority as rocket launches, spacecraft, and the exploration of worlds beyond our own.

In celebration of Earth Day 2024, nearly 100 students from Andrew Jackson Middle School in Titusville, Florida, and a virtual audience of students across the country, attended NASA’s Next Gen STEM Earth Day panel at the NASA News Center’s John Holliman Auditorium and press site “bullpen.”  

On hand were NASA environmental and educational experts who discussed Kennedy’s unique role balancing space launch technology and protected habitat, the center’s new electric vehicle charging stations, and NASA’s Earthrise educational initiative that aims to increase science, technology, engineering, and mathematics literacy. 

Bob Kline, acting chief of Kennedy’s Environmental Assurance Branch, helped students learn about the importance of protecting the habitat that is refuge to more than 1,500 species of plants and animals. NASA Kennedy shares a boundary with the Merritt Island National Wildlife Refuge and the Canaveral National Seashore, which encompass over 140,000 acres of land, waters, and protected habitats.   

“Because we’re a wildlife refuge, it’s easy to think the launches would impact the wildlife, but it’s mostly the buildings that might get impacted by wildlife trying to live on them,” said Kline. “During renovations we’ve had to do special things to protect bats and other birds who live in roofs or under bridges. Everything we do, we’re very mindful of the animals, whether they’re endangered or not. We care about them deeply.” 

Panelist Kim King-Wrenn, a park ranger from Merritt Island National Wildlife Refuge, echoed Kline’s message. She told students that the spaceport is one of the most biologically diverse places in the world. 

Home to everything from the Florida scrub jay to endangered green sea turtles, King-Wrenn classifies Kennedy as the goldilocks of climate zones.  

“Right here is where the northern temperate zone and the southern, subtropical zones come together,” King-Wrenn said. “The more habitat diversity there is, the more diverse homes there are for more kinds of animals.”  

Students like 7th grader Zoe Oderman were fascinated by the coexistence of nature and technology across the spaceport. “The Vehicle Assembly Building was awesome, but I love that the beaches at Kennedy Space Center give turtles a place to lay their eggs, because other places in the area don’t,” Oderman said.  

Kennedy employee Spencer Davis discussed the installation of 56 electric vehicle charging stations during his time at the NASA Transportation Office on center. The new infrastructure helps support a fleet of electric government vehicles including the all-electric crew transport vehicles that will take Artemis astronauts from their crew quarters to the launch pad.

As part of NASA’s NextGen STEM project, the students joined others from across the country who participated virtually for an environmentally focused Earth Day briefing held inside Kennedy’s news auditorium to discuss how technology and science coexist with nature at the spaceport.

Later this summer, Davis and his team will be honored at the White House for these efforts to facilitate a future of zero carbon emission government vehicles and help save taxpayer money.  

“The big takeaway here is in order to charge up and drive one of Kennedy’s Chevrolet Bolts 100 miles, it only costs $2.80,” Davis said. “That’s basically the price of a soft drink.”  

The students also learned about Earthrise from panelist Kelly McCarthy, program specialist with NASA’s Office of STEM Engagement at the agency’s Stennis Space Center in Mississippi.  

The NASA education initiative provides educators with access to monthly collections of resources aimed at increasing STEM literacy and understanding the importance of protecting our home planet.  

“Earthrise is a really good way to find out the most relevant and useful solutions-based resources that exist right now,” McCarthy said. 

Besides offering their expertise on sustainable practices as well as words of encouragement to the future stewards of our planet, the panelists inspired students to pursue STEM careers, including at Kennedy. 

“You can do anything you want to do out here, and if you really apply yourself you can get into any field,” Davis told the students. “Don’t be afraid to step outside the box. Don’t be afraid to do something completely different, even if it’s scary. Take every opportunity and seize the moment.”

The event was coordinated through the Next Gen STEM project in NASA’s Office of STEM Engagement, which reaches students in schools and informal classrooms across the county.
