Satellite Observations to Benefit Science and Society: Recommended Missions for the Next Decade
HyspIRI HYPERSPECTRAL INFRARED IMAGER
LAUNCH: 2013–2016
MISSION SIZE: Medium
ORBIT: LEO, SSO
AGENCY: NASA
ESTIMATED COST: $300 million
AREAS OF INTEREST: Ecosystems, Health, Solid Earth
INSTRUMENTS: Hyperspectral spectrometer
BENEFITS:
Data on changes in vegetation type and deforestation for ecosystem management and monitoring of changes in carbon sinks
Early warnings of drought
Improved exploration for natural resources
Predictions of the likelihood of volcanic eruptions and landslides
Highly detailed images of Earth’s surface are invaluable for studying and managing ecosystems and other natural resources. Satellite-based sensors can detect early signs of drought, soil types prone to landslides, volcanic unrest that may precede eruptions, and changes in the health and extent of coral reefs. Forest and agricultural managers can make use of timely, high-resolution images from space in responding to fires, the effects of invasive species, and other ecosystem threats. This imagery also helps scientists analyze climate variability and longer-term climate change.
HyspIRI will employ a hyperspectral imager and a thermal infrared scanner to monitor a variety of ecological and geological features at a wide range of wavelengths. The system will take advantage of recent advances in detectors, optics, and electronics to provide global coverage every 30 days at a resolution of 45 meters. Both instruments would be pointable, to allow for frequent high-resolution sampling of volcanic activity, wildfires, droughts, and other critical events. The system would also map surface rock and soil composition, in many cases with a quality close to that provided by laboratory X-ray diffraction analysis. These data would benefit exploration for natural resources as well as environmental remediation activities.
