An introduction to the NASA Hyperspectral InfraRed Imager (HyspIRI) mission and preparatory activities

- The HyspIRI mission was recommended in the 2007 Earth Science Decadal Survey.
- HyspIRI would have 2 instruments: a VSWIR imaging spectrometer and a multiband TIR.
- Global coverage, frequent revisits (5-16 days), good spatial resolution (30-60 m)
- HyspIRI addresses unique and urgent Earth science and applications objectives.

In 2007, the NASA Hyperspectral InfraRed Imager (HyspIRI) mission was recommended in Earth Science and Applications from Space: National Imperatives for the Next Decade and Beyond (Decadal Survey) to address critical science questions in multiple areas, in particular ecosystems and natural hazards. HyspIRI is comprised of two instruments, a visible to short-wavelength infrared (VSWIR) imaging spectrometer and a thermal infrared (TIR) multispectral imager, together with an Intelligent Payload Module (IPM) for onboard processing and rapid downlink of selected data. The VSWIR instrument will have 10 nm contiguous bands and cover the 380-2500 nm spectral range with 30 m spatial resolution and a revisit of 16 days. The TIR instrument will have 8 discrete bands in the 4-13 μm range with 60 m spatial resolution and a revisit of 5 days. With these two instruments in low Earth orbit, HyspIRI will be able to address key science and applications questions in a wide array of fields, ranging from ecosystem function and diversity to human health and urbanization.
