NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument recorded this image of ground surface temperatures in Dallas and Fort Worth, Texas, on June 20, 2022, at 7:17 a.m. Central Daylight Time. Even early in the day, manmade urban surfaces near city centers and transportation networks – streets, roads, and highways shown in red and orange – are warmer than the outskirts by up to 18 degrees Fahrenheit (10 degrees Celsius). The paved surfaces at Dallas/Fort Worth International Airport, shown in red near the top-center of the image, had the warmest temperatures, exceeding 86 F (30 C). Natural land surfaces such as vegetation and streams in rural areas, shown in green and blue, are cooler than nearby large bodies of water, shown in red and yellow, that tend to retain more heat overnight due to their higher heat capacity. Cities are usually warmer than open land because of human activities and the materials used in building and construction. Streets are often the hottest part of the built environment due to asphalt paving. Dark-colored surfaces absorb more heat from the Sun than lighter-colored ones; asphalt absorbs up to 95% of solar radiation and retains the heat for hours into the nighttime. ECOSTRESS measures the temperature of the ground, which is hotter than the air temperature during the daytime. The instrument launched to the space station in 2018. Its primary mission is to identify plants' thresholds for water use and water stress, giving insight into their ability to adapt to a warming climate. However, ECOSTRESS is also useful for documenting other heat-related phenomena, like patterns of heat absorption and retention. Its high-resolution images, with a pixel size of about 225 feet (70 meters) by 125 feet (38 meters), are a powerful tool for understanding our environment. https://photojournal.jpl.nasa.gov/catalog/PIA25422

NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument recorded this image of ground surface temperatures in London and surrounding areas on July 15, 2022, just before midnight local time. It shows surface temperatures exceeding 68 degrees Fahrenheit (20 degrees Celsius) at 11:57 p.m. British Summer Time. Parts of Europe in mid-July experienced a record-breaking heat wave. The United Kingdom reaching its highest air temperature on record on July 19, 104.5 F (40.3 C) in Coningsby, about 110 miles (177 kilometers) north of London, which itself saw a high of 104.3 F (40.2 C) the same day. That evening, the overnight low was also a record-breaker: 78.4 F (25.8 C) at Kenley Airfield in Greater London. In this image, the red areas indicate hotter temperatures commonly associated with developed areas. These surfaces – roofs, paved streets, and other built structures – remain warm long after the sun sets. Blue and green areas indicate cooler areas commonly associated with parks and other natural land surfaces. Because this image was acquired at night, it shows bodies of water being warmer than the land surface. This is because water tends to change temperature more slowly, so its temperature stays elevated long after land surfaces have cooled down. Cities are usually warmer than open land with natural surfaces because of human activities as well as the materials used in building and construction. Streets are often the hottest part of the built environment due to asphalt paving. Dark-colored surfaces absorb more heat from the Sun than lighter-colored ones; asphalt absorbs up to 95% of solar radiation and retains the heat for hours into nighttime. This image overlays ECOSTRESS surface temperature data on a Google satellite map for context.

The Western United States has been entrenched in an Extreme and Exceptional drought that has extended from the summer and into the fall of 2020. NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) imaged the drought on Oct. 16, 2020, and compared the same area to an image from ECOSTRESS taken a year earlier on Oct. 16, 2019. The bottom image shows the percentage change in plant water stress from 2019 to 2020. The images at left zoom into the Arizona and New Mexico border and Navajo Nation Territory area, featuring the ECOSTRESS Evaporative Stress Index (ESI), which shows plant water stress. The inset images on the right zoom further into the region, showing circular agricultural fields that have been irrigated. Blue colors represent low stress and high water use, whereas red colors represent high stress and low water use. Irrigation is able to alleviate plant water stress in many of the fields while the surrounding landscape suffers from the drought, though numerous agricultural fields are shut down in the drought image. The primary mission of ECOSTRESS, which launched to the International Space Station in June 2018, is to provide insight into plants' health, especially in a drought, by taking their temperature. Plants regulate their temperature by releasing water through tiny pores on their leaves. With sufficient water, they can maintain their temperature. When they lack water, their temperatures rise; ECOSTRESS can measure this change. https://photojournal.jpl.nasa.gov/catalog/PIA24132

NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) is aiding in the fight against fires in the Western U.S. As of July 27, 2021, the Bootleg Fire in southern Oregon had ballooned to more than 410,000 acres, damaging hundreds of buildings and vehicles in its path. ECOSTRESS measures surface temperature from the vantage point of the International Space Station. Researchers of the RADR-Fire team at Pacific Northwest National Laboratory have been experimenting with ECOSTRESS data as part of a new tool now being implemented for first responders like the U.S. Forest Service. In the visualization, ECOSTRESS is tracking the movement of the Bootleg Fire between July 7 and July and identifying its proximity to critical infrastructure — areas in red represent the hottest pixels ECOSTRESS detected. The extreme heat in those areas indicates the fire front, or where resources are most needed. Tasked with detecting plant water use and stress, ECOSTRESS's primary mission is to measure the temperature of plants heating up as they run out of water. But it can also measure and track heat-related phenomena like wildfires, heat waves, and volcanoes. ECOSTRESS observations have a spatial resolution of about 77 by 77 yards (70 by 70 meters), which enables researchers to study surface-temperature conditions down to the size of a football field. Due to the space station's unique orbit, the mission can acquire images of the same regions at different times of the day, as opposed to crossing over each area at the same time of day like satellites in other orbits do. This is advantageous when monitoring plant stress in the same area throughout the day, for example. Movie available at https://photojournal.jpl.nasa.gov/catalog/PIA23695

NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) sensor measured the water-stress levels of plants when it passed over the Peruvian Amazon rainforest on Aug. 7, 2019, before the fires there began. The map shows areas of plants in distress (brown) and areas of less stress (blue). Water-stressed plants released measurably less water vapor into the air at the time of the summer fires. The fire icons represent fires imaged by NASA's Terra satellite between Aug. 19 and 26. The burn pattern reveals that the fires were concentrated in areas of highly water-stressed plants, pointing to how water-stressed plants can impact the spread of fires. The data may one day help NASA's Earth-observing missions predict the path of future forest or brush fires. https://photojournal.jpl.nasa.gov/catalog/PIA23432

NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) imaged the temperature of Hurricane Dorian from the International Space Station on Sept. 6, 2019 as the storm made landfall in North Carolina. ECOSTRESS senses the amount of emitted infrared radiation from Earth, which is converted into an equivalent temperature scale in units of degrees Kelvin. In the image, red colors such as the well-defined eye represent warmer temperatures while purple/blue represent the cooler cloud top temperatures of strong storm clouds with the potential of producing heavy rain. The temperature patterns reveal fine cloud structures that contribute to the formation of the larger hurricane. The width of the image (~400 km) is based on what ECOSTRESS sees as the Space Station flies over any given spot on Earth. ECOSTRESS launched to the space station in June 2018. It can measure variations in temperature to within a few tenths of a degree and is able to detect temperature changes at various times of day over areas as small as a football field. ECOSTRESS' primary mission is to detect plant health from space; however, its measurements can be used to detect other heat-related phenomena — including urban heat, fires, and volcanic activity — as well. Although disaster response is not one of its primary objectives, these highly detailed hurricane temperature estimates can be used to improve weather models. https://photojournal.jpl.nasa.gov/catalog/PIA23422

Astronaut Donald Thomas conducts the Fertilization and Embryonic Development of Japanese Newt in Space (AstroNewt) experiment at the Aquatic Animal Experiment Unit (AAEU) inside the International Microgravity Laboratory-2 (IML-2) science module. The AstroNewt experiment aims to know the effects of gravity on the early developmental process of fertilized eggs using a unique aquatic animal, the Japanese red-bellied newt. The newt egg is a large single cell at the begirning of development. The Japanese newt mates in spring and autumn. In late autumn, female newts enter hibernation with sperm in their body cavity and in spring lay eggs and fertilized them with the stored sperm. The experiment takes advantage of this feature of the newt. Groups of newts were sent to the Kennedy Space Center and kept in hibernation until the mission. The AAEU cassettes carried four newts aboard the Space Shuttle. Two newts in one cassette are treated by hormone injection on the ground to simulate egg laying. The other two newts are treated on orbit by the crew. The former group started maturization of eggs before launch. The effects of gravity on that early process were differentiated by comparison of the two groups. The IML-2 was the second in a series of Spacelab flights designed to conduct research by the international science community in a microgravity environment. Managed by the Marshall Space Flight Center, the IML-2 was launch on July 8, 1994 aboard the STS-65 Space Shuttle Orbiter Columbia mission.

This observation shows the burn area and smoke plume created by the Apple fire in Southern California on Aug. 1, 2020. The observation was made possible by NASA's Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS). Data gathered by the mission can be further refined to measure the temperature of the wildfire, smoke plume and surrounding landscape. ECOSTRESS collected this data when the space station passed over the region at about 1:15 p.m. PST on Saturday, Aug. 1, 2020, when the burn area was approximately 4,000 acres in size. As of Aug. 3, it was more than 26,000 acres. Black smoke can be seen drifting east and over Joshua Tree National Park in the Mojave Desert. With a resolution of about 77 by 77 yards (70 by 70 meters), the image enables surface-temperature conditions down to the size of a football field to be studied. Tasked with detecting plant water use and stress, ECOSTRESS measures the temperature of plants as they heat up when they run out of water. But it can also measure and track heat-related phenomena like fires, heat waves, and volcanoes. https://photojournal.jpl.nasa.gov/catalog/PIA23799

On July 8, NASA's ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument captured ground surface temperature data over California. In the image, areas in red – including Death Valley – had surpassed 86 degrees Fahrenheit (30 degrees Celsius) by 7:16 a.m. local time, well above average ground surface temperatures for the area.
