Engineers in a clean room at NASA's Jet Propulsion Laboratory in Southern California in April 2023 examine the imaging spectrometer that will ride aboard the first of two satellites to be launched by the Carbon Mapper Coalition. The instrument will help researchers detect emissions of carbon dioxide and methane from sources on Earth's surface from space. The gold-colored component is the spectrometer, which was developed at JPL. It's designed to receive sunlight reflected from Earth and divide that light into hundreds of distinct colors in the near-infrared and visible portion of the electromagnetic spectrum. By analyzing the light's spectroscopic signature – the wavelengths that show up in the signal as well as those that do not – researchers can determine whether the instrument is observing greenhouse gas emissions and, if so, estimate their concentrations. The black portion at the base of the instrument is a telescope that captures light from Earth's surface and reflects it into the spectrometer. When released into the atmosphere, carbon dioxide and methane are the greenhouse gases most responsible for human-caused global warming. Both have unique spectral signatures that make them detectable from space via spectroscopy. The imaging spectrometer is JPL's contribution to the Carbon Mapper Coalition, a joint effort led by the nonprofit Carbon Mapper that also includes Planet Labs PBC, the California Air Resources Board, Arizona State University, and the University of Arizona. Once the instrument is in orbit, researchers will use its measurements to identify the sources of carbon dioxide and methane plumes it detects. Identification of the origins of emissions is considered the first step towards mitigation. https://photojournal.jpl.nasa.gov/catalog/PIA25869
JPL Engineers Work on Carbon Mapper Imaging Spectrometer
An artist's concept depicts one of the Carbon Mapper Coalition's Tanager satellites, which will use imaging spectrometer technology developed at NASA's Jet Propulsion Laboratory in Southern California to measure methane and carbon dioxide point-source emissions, down to the level of individual facilities and equipment, on a global scale. The Tanager-1 satellite, launched from Vandenberg Space Force Based in California on Aug. 16, 2024, was developed as part of a philanthropically funded public-private coalition led by the nonprofit Carbon Mapper. JPL and Planet Labs PBC, which built Tanager-1, are both members of the Carbon Mapper Coalition. The group plans to launch a second Tanager satellite, called Tanager-2, also being built by Planet Labs and equipped with a JPL-built imaging spectrometer. https://photojournal.jpl.nasa.gov/catalog/PIA26411
Carbon Mapper Coalition's Tanager Satellite
The Carbon Mapper Coalition's Tanager-1 satellite on Sept. 19, 2024, captured data over Karachi, Pakistan, showing the location and concentration of a methane plume measuring about 2½ miles (4 kilometers) long, emanating from a landfill. Enabled by the nonprofit Carbon Mapper and built by Planet Labs PBC, Tanager-1 uses an imaging spectrometer designed by NASA's Jet Propulsion Laboratory in Southern California. Carbon Mapper's preliminary estimate of the source emissions rate is about 2,600 pounds (1,200 kilograms) of methane released per hour. Launched from Vandenberg Space Force Base in California on Aug. 16, 2024, Tanager-1 is part of a broader effort by the nonprofit Carbon Mapper to identify and measure greenhouse gas point-source emissions on a global scale. Both Planet and JPL are members of the philanthropically funded Carbon Mapper Coalition. https://photojournal.jpl.nasa.gov/catalog/PIA26416
Tanager-1 First Methane and Carbon Dioxide Plume Detections
An imaging spectrometer designed by NASA's Jet Propulsion Laboratory captured its first data over Karachi, Pakistan, on Sept. 19, 2024. The instrument is aboard the Carbon Mapper Coalition's Tanager-1 satellite, which was built by Planet Labs PBC. An imaging spectrometer can measure hundreds of wavelengths of light that are reflected by Earth's surface. Different compounds in the planet's atmosphere and on the ground absorb different wavelengths of light, leaving spectral "fingerprints" that researchers can identify. The imaging spectrometer aboard Tanager-1 will enable the satellite to measure methane and carbon dioxide point-source emissions, down to the level of individual facilities and equipment, on a global scale. The image at the front of the cube shows a mix of information on land cover and water in the city and surrounding area, including exposed soil (brown), vegetation (green), and clouds. The rainbow colors extending through the main part of the cube are the wavelengths of light from corresponding spots in the front image. Tanager-1, which launched on Aug. 16, 2024, was developed as part of a philanthropically funded public-private coalition led by the nonprofit Carbon Mapper. Planet Labs and JPL are both members of the Carbon Mapper Coalition. https://photojournal.jpl.nasa.gov/catalog/PIA26412
Tanager-1 First Light
This spectral "fingerprint" of methane was produced from data taken during a September 2023 test at NASA's Jet Propulsion Laboratory in Southern California of a state-of-the-art imaging spectrometer that will measure the greenhouse gases methane and carbon dioxide from space. The instrument measures hundreds of wavelengths of light reflected by Earth's surface and absorbed by gases in the planet's atmosphere. Different compounds absorb different wavelengths of light, leaving a kind of spectral fingerprint that the imaging spectrometer can identify. These infrared fingerprints, invisible to the human eye, can pinpoint and quantify strong greenhouse gas emissions, and accelerate mitigation efforts. Before the imaging spectrometer was shipped from JPL to Planet Labs PBC in San Francisco, where it will be integrated into a Tanager satellite, there was a rare opportunity to use a sample of methane to test the completed instrument while it was in a vacuum chamber. The test was successful, and the imaging spectrometer produced this clear spectral fingerprint of methane (appearing as a red line in the graph). Designed and built by JPL, imaging spectrometer will be part of an effort led by the nonprofit Carbon Mapper organization to collect data on greenhouse gas point-source emissions. The information will help locate and quantify "super-emitters" – the small percentage of individual sources responsible for a significant fraction of methane and carbon dioxide emissions around the world. https://photojournal.jpl.nasa.gov/catalog/PIA26095
