The NASA Breath Diagnostics challenge tasks solvers to leverage their expertise to develop a classification model that can accurately discriminate between the breath of COVID-positive and COVID-negative individuals, using existing data. The ultimate goal is to improve the accuracy of the NASA E-Nose device as a potential clinical tool that would provide diagnostic results based on the molecular composition of human breath.
Award: $55,000 in total prizes

NASA Science Activation Teams Present at National Rural STEM Summit
NASA Science Activation (SciAct) teams participated in the National Rural STEM (Science, Technology, Engineering, & Mathematics) Summit held June 4-7, 2024 in Tucson, Arizona. Hosted by Kalman Mannis of the Rural Activation and Innovation Network (Arizona Science Center) and the SciTech Institute, the summit fostered learning and sharing among organizations dedicated to creating partnerships and pathways for authentic STEM learning in rural communities.
Participants included:
Matt Cass and Randi Neff from SciAct’s Smoky Mountains STEM Collaborative, who presented “A sense of place: Crafting authentic experiences for rural STEM learners”; Tina Harte from NASA (Science Systems and Applications, Inc), who presented “Nature explorations with NASA”; Kalman Mannis from the SciAct STEM Ecosystems project and the Rural Activation and Innovation Network, who presented “Building leaders in STEM through coaching, connections, and camaraderie”; and members of the SciAct Rural Committee. SciAct STEM Ecosystems is supported by NASA under cooperative agreement award number 80NSSC210007 and is part of NASA’s Science Activation Portfolio. Learn more about how Science Activation connects NASA science experts, real content, and experiences with community leaders to do science in ways that activate minds and promote deeper understanding of our world and beyond: https://science.nasa.gov/learn

Firefly Aerospace’s Alpha rocket leaves a glowing trail above the skies of Vandenberg Space Force Base in California on July 3, 2024. Firefly Aerospace/Trevor Mahlmann As part of NASA’s CubeSat Launch Initiative, Firefly Aerospace launched eight small satellites on July 3 aboard the company’s Alpha rocket. Named “Noise of Summer,” the rocket successfully lifted off from Space Launch Complex 2 at Vandenberg Air Force Base in California at 9:04 p.m. PDT.
The CubeSat missions were designed by universities and NASA centers and cover science that includes climate studies, satellite technology development, and educational outreach to students.
Firefly Aerospace completed its Venture-Class Launch Services Demonstration 2 contract with this launch. The agency’s venture-class contracts offer launch opportunities for new providers, helping grow the commercial launch industry and leading to cost-effective competition for future NASA missions.
NASA’s CubeSat Launch Initiative provides a low-cost way for universities, non-profits, science centers, and other researchers to conduct science and technology demonstrations in space.

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.
