NASA’s ECOSTRESS Maps Burn Risk Across Phoenix Streets

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s ECOSTRESS instrument on June 19 recorded scorching roads and sidewalks across Phoenix where contact with skin could cause serious burns in minutes to seconds, as indicated in the legend above.
NASA/JPL-Caltech
Roads and sidewalks in some areas get so hot that skin contact could result in second-degree burns.
Researchers at NASA’s Jet Propulsion Laboratory in Southern California have mapped scorching pavement in Phoenix where contact with skin — from a fall, for example — can cause serious burns. The image shows land surface temperatures across a grid of roads and adjacent sidewalks, revealing how urban spaces can turn hazardous during hot weather.
Data for this visualization of the Phoenix area — the fifth most populous city in the United States — was collected at 1:02 p.m. local time on June 19, 2024, by a NASA instrument aboard the International Space Station. Called ECOSTRESS (short for the Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station), the instrument measures thermal infrared emissions from Earth’s surface.
The image shows how miles of asphalt and concrete surfaces (colored here in yellow, red, and purple, based on temperature) trap heat. The surfaces registered at least 120 degrees Fahrenheit (49 degrees Celsius) to the touch — hot enough to cause contact burns in minutes to seconds.
The image also shows cooling effects of green spaces in communities like Encanto and Camelback East, in contrast to the hotter surface temperatures seen in Maryvale and Central City, where there are fewer parks and trees.
“We create these maps to be intuitive to users and help make data more accessible to the public and citizens scientists,” said Glynn Hulley, a JPL climate researcher. “We see them as a vital tool for planning effective heat interventions, such as tree planting, that can cool down the hottest roads and sidewalks.”
Homing in on Heat
At the lower right of the image is Phoenix’s Sky Harbor International Airport, where ECOSTRESS recorded some of the hottest land surface temperatures within the city —around 140 F (60 C). The air temperature on June 19 at the airport reached 106 F (43 C).
Air temperature, which is measured out of direct sunlight, can differ significantly from the temperature at the land surface. Streets are often the hottest surfaces of the built environment due to dark asphalt paving that absorbs more sunlight than lighter-colored surfaces; asphalt absorbs up to 95% of solar radiation. These types of surfaces can easily be 40 to 60 degrees F (22 to 33 degrees C) hotter than the air temperature on a very hot day.
Launched to the International Space Station in 2018, ECOSTRESS has as its primary mission the identification of plants’ thresholds for water use and water stress, giving insight into their ability to adapt to a warming climate. But the instrument is also useful for documenting other heat-related phenomena, like patterns of heat absorption and retention.
To produce the image of Phoenix, scientists used a machine learning algorithm that incorporates data from additional satellites: NASA/USGS Landsat and Sentinel-2. The combined measurements were used to “sharpen” the surface temperatures to a resolution of 100 feet (30 meters) by 100 feet (30 meters).
More About the Mission
JPL built and manages the ECOSTRESS mission for the Earth Science Division in the Science Mission Directorate at NASA Headquarters in Washington. ECOSTRESS is an Earth Venture Instrument mission; the program is managed by NASA’s Earth System Science Pathfinder program at NASA’s Langley Research Center in Hampton, Virginia.
NASA astronaut Matthew Dominick captured this image of Hurricane Beryl in the Caribbean on July 1, 2024, while aboard the International Space Station, and posted it to X. The Category 4 hurricane had winds of about 130 mph (215 kph).
Hurricanes – tropical cyclones that form over the Atlantic Ocean or the eastern Pacific Ocean – use warm, moist air as fuel. The warm, moist air over the ocean rises upward from near the surface, causing an area of lower air pressure below. Air from surrounding areas with higher air pressure pushes into the low pressure area. Then that “new” air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean’s heat and water evaporating from the surface.

NASA Stennis Hosts Take Our Children to Work Day
Gator Speaks
Conversations filled the room with anticipation for the day ahead.
NASA’s Stennis Space Center hosted Take Our Children to Work Day on June 27 with a day set aside for children of employees to see up close the work carried out at NASA Stennis by its diverse workforce.
A video featuring NASA Stennis Associate Director Rodney McKellip welcomed the enthusiastic crowd. He shared about the different hats worn by the more than 5,000 employees throughout the NASA Stennis federal city.
There are engineers who help make the south Mississippi NASA center the premier rocket engine test facility in the country. NASA Stennis, the place that tested rocket stages to put the first humans on the Moon, remains on the frontlines of preparing NASA and the United States for its return to the Moon through the Artemis campaign to explore more of the lunar surface than ever before.
Those attending Take Our Children to Work Day learned how NASA Stennis has many rocket scientists and test engineers carrying out this work, but that is not all.
Gator Speaks
NASA/Stennis
A team of folks, including accountants, lawyers, environmental specialists, educators, and public affairs specialists, wear the NASA hat to ensure mission success too.
There also are teams climbing on test stands, installing rocket engines into the stands, working with piping, electrical, welding, construction projects, safety inspections, and more.
In addition to being the premier propulsion test site supporting NASA’s mission, NASA Stennis is where commercial companies experience success and benefit from the expertise of NASA personnel. Companies like Relativity Space, Rocket Lab, and Evolution Space have established ongoing operations at NASA Stennis as the commercialization of space continues.
The NASA Stennis federal city also includes a range agencies, universities, and companies sharing costs and carrying out individual missions.
It is the command site for the largest collection of oceanographers in the world and where Navy Seals train.
Participants learned about such operations from a panel of employees from NASA, Aerojet Rocketdyne, an L3 Harris Technologies company, Lockheed Martin, and Relativity Space.
They toured NASA Stennis and participated in activities facilitated by NASA, Aerojet Rocketdyne, and the National Data Buoy Center.
The NASA Stennis associate director left them with a final thought before their day started: If you hear something loud during the day, just know that is the sound of progress at the nation’s premier rocket propulsion test facility and federal city known as NASA Stennis.
Sure enough, that afternoon, the unmistakable sound of engine testing could be heard across the site. For this ol‘ Gator, it sounds like music to the ears.

NASA Stennis Achieves Primary Success for Historic In-Space Mission
NASA’s Stennis Space Center and partner Sidus Space Inc. announced primary mission success July 2 for the center’s historic in-space mission – an autonomous systems payload aboard an orbiting satellite.
Science fiction fans at the Mississippi Comic Convention were provided an out-of-this world experience, while learning about NASA, during the two-day event in Jackson, Mississippi, thanks to employees from NASA’s Stennis Space Center.
“I’ve never been to an outreach activity that you reached so many people and from such a wide spectrum of people, from grade schoolers to retired grandparents,” said Troy Frisbie, NASA Stennis legislative affairs officer and chief of staff. “We interacted with a wide audience and really shared how NASA and NASA Stennis benefit all. It was a really, really good experience.”
The NASA booth, at an event that attracted 18,000 people to the Mississippi Trade Mart and Coliseum on June 22-23, featured an immersive experience with virtual reality goggles. Participants were able to view an engine test conducted at NASA Stennis, take a virtual spacewalk while visiting the International Space Station, and experience a simulated rocket launch to Mars.
One group enjoying the interaction with NASA was the Star Trek fan club from Jackson, Mississippi.
“They were real big supporters of NASA,” Frisbie said. “They loved the virtual reality experience and encouraged others at the convention to come by and visit with us.”
NASA Stennis budget analyst Rebecca Mataya and engineers Paul Fuller, Steven Helmstetter, and Chris Barnett-Woods volunteered with Frisbie. The center employees talked to college students majoring in engineering, graphic design, architecture, education, and healthcare.
“The assumption is everybody has to be an engineer to work at NASA, and that is not the case,” Frisbie said. “There are all kinds of opportunities, and that was an eye opener for many.”
Conversations centered on job opportunities and careers with NASA, as well as work conducted at NASA Stennis. The volunteers also fielded general questions about NASA’s powerful SLS (Space Launch System) rocket and the agency’s Artemis campaign of returning astronauts to the Moon for scientific discovery, economic benefits, and inspiration for a new generation of explorers: the Artemis Generation.
“We enjoyed telling the NASA story and how NASA Stennis on the Gulf Coast of Mississippi serves as an economic engine that contributes to this nation’s space dreams,” Frisbie added.
