Gulfstream V Research Aircraft

The Johnson Space Center (JSC) procured a long-range Gulfstream GV aircraft as part of a shared usage agreement between the International Space Station (ISS) Program and the NASA Earth Sciences Division (ESD). The ISS Program will use this aircraft to fulfill the Soyuz Direct and Commercial Crew Program Crew Return missions, and ESD will use this aircraft to support airborne science missions in remote locations around the world. The collaboration between the ISS Program and ESD replicates the successful shared usage model currently implemented by JSC on the Gulfstream GIII aircraft and provides the agency a business jet to serve as a true long range platform to execute missions around the world.

AVIRIS-NG

The AVIRIS-NG is a whisk-broom imaging spectrometer with a spectral range of 380-2510 nm and sampling resolution of 5nm.

HyTES

The HyTES sensor is a hyperpectral imaging spectrometer measuring thermal emission in the 7.5 μm-12 μm range. It will provide ecosystem diversity metrics in terrestrial settings and physical marine measurements (e.g. sea surface temperatures)

PRISM

The PRISM sensor is a pushbroom imaging spectrometer with a spectral range from 350-1050 nm as well two bands in the short wave infrared (SWIR) spectral region. It’s primary function will be to explore marine and freshwater ecosystem distribution, structure and composition.

LVIS

The Land, Vegetation, and Ice Sensor (LVIS) is a laser altimeter scanner able to produce 3-D images of topography and vegetation. Data from LVIS would be fused with spectral information from the above scanners to enhance biodiversity observation and prediction.
