Tanager-1
Earth observation greenhouse gas satellite
From Wikipedia, the free encyclopedia
Tanager-1 is an Earth observation satellite designed to detect and measure emissions of greenhouse gases, particularly methane and carbon dioxide, at the level of individual facilities. It is the first satellite deployed for the Carbon Mapper initiative and was launched on 16 August 2024 aboard a Falcon 9 rocket from Vandenberg Space Force Base in California.[1][2][3]

The satellite carries a hyperspectral imaging spectrometer developed at NASA's Jet Propulsion Laboratory (JPL) and was built and operated by Planet Labs as part of a public-private collaboration involving scientific and nonprofit organisations.[2][4]
Background
Tanager-1 was developed to improve the detection and monitoring of high-intensity greenhouse gas emission sources, including methane emissions from industrial infrastructure.[1] The mission forms part of broader efforts to expand satellite-based atmospheric monitoring and provide data for scientific and policy applications.[2][5]
Development and launch
Tanager-1 was developed through the Carbon Mapper partnership, which includes NASA's Jet Propulsion Laboratory and Planet Labs.[6][3]The satellite was launched on 16 August 2024 aboard SpaceX's Transporter rideshare mission from Vandenberg Space Force Base in California.[2][3]
Following launch, mission operators established communication with the spacecraft and initiated commissioning procedures to verify instrument performance.[3]
Mission and instrumentation
Tanager-1 carries a hyperspectral imaging spectrometer that measures reflected light across multiple wavelengths, allowing detection of atmospheric gases based on their spectral signatures.[2][7]The satellite is designed to detect, locate, and quantify methane and carbon dioxide emissions from specific sources such as landfills and energy infrastructure.[8][5]
Early observations identified greenhouse gas plumes in several regions following commissioning of the instrument.[8][5]
