PRISM

Hi!!

Today I am going to talk about one of the current missions that are happening out there in the space.

This current mission which I am talking about has an acronym which is Prism and it was launched in 2012. It is an instrument whose target is the Earth's Surface and Atmosphere.

The coastal zone is home to a high fraction of humanity and day by day is increasingly affected by natural and human-induced events from tsunamis to toxic blooms and oil spills. Current satellites provide a broad overview of these events but do not have the necessary spectral, spatial and temporal, resolution to characterize and understand them.

Prism's goal is to address this gap.

A compact, lightweight, airborne Portable Remote Imaging Spectrometer (PRISM) was developed at the Jet Propulsion Laboratory. Optimized for the spectral range, PRISM offers high temporal resolution and below cloud flight altitudes to resolve spatial features as small as 30 cm. The sensor performance defines the state of the art in light throughput, spectral and spatial uniformity, and polarization insensitivity.

PRISM also has a two-channel spot radiometer at short-wave infrared (SWIR) band (1240 nm and 1640 nm) in order to provide accurate atmospheric correction of the ocean colour measurements.

To date, PRISM has flown on two Twin Otter aircraft from NASA's Glenn Research Center and Twin Otter International. Additional options are being explored and development is underway which will allow integration on other aircraft, including pressurized/high-altitude platforms that will enable wide area coverage. Imagine preserving finding another way to preserve the planet... And to prevent the deformation of the coastal zone, sure. Continue online with me to know about updates and more cool stuff!
