Project Overview
• Funded through a NASA Cooperative Agreement Notice. 
• Partner provides 50% of resources for project. 
• One year period of performance
• The technical challenge: to effect the transition of tunable, snapshot hyperspectral 
imaging technology from the biomedical domain to that of Earth remote sensing by 
reducing instrument to 5kg and cubesat like volume.
• Benefit to NASA: Advances the MSFC science goals of developing instruments that 
examine Earth science processes on small and regional scales, and that benefit 
humanity for disaster response and public health.

Objective
1) Take an existing benchtop hyperspectral imager used for medical applications and reduce 
it in size to <5kg and approaching a 3U cubesat format
2) Demonstrate the ability to capture tunable snapshot hyperspectral imagery
• Benchtop camera was 
reduced in size to fit within 
the payload requirements 
for octocopter unoccupied 
aerial system.
• SNAP-IMS was integrated 
into UAS and collected 
hyperspectral data over 
NASA test area.
4SNAP-IMS
Camera produced image data in a matrix of 350x350 pixels x 66 layers and written to .tif files
Each layer is a spectral channel-spectral channels range from 473 to 668 in 3 nm increments.
Initial processing of data into RGB files shows discernible structure. 
Left image shows concrete retaining walls. The bright dot is sunlight reflected off a convex mirror.
Reconstructed image 
of scene over NASA 
test area.
• Processed data is 
calibrated to sunlight 
reflected from mirror 
in the scene.
• Spectral data can be 
extracted from 
individual pixels.

This activity supports the desire of the MSFC Earth Science Office to develop 
small instrument payloads suitable for collecting data from various platforms 
such as cubesats, small sats, UAS of various sizes and occupied aerial 
vehicles.
