Introduction
The primary goal of the POLARIS (Polar Orbit, Lower Atmosphere Research Instrument using Spectroscopy) cubesat is to provide infrared spectral imagery from the Earth's upper atmosphere using the cost-efficient Aurora multi-pixel camera made by Thoth Technologies. The captured images will allow for analysis of numerous greenhouse gases in the atmosphere that is useful for understanding climate change (Fig. 1). This mission will demonstrate the radiation balance of the Earth by understanding the upwelling radiation and help to quantify the effects of clouds, aerosols, water vapor, and carbon dioxide on the climate (Fig. 2). Our secondary objectives are to:
Promote space exploration to our local community and university.
Demonstrate in a cost-effective manner the extensive capabilities of nano-satellites.
Provide a hands-on learning experience for our engineering and science students.
Typical infrared spectrograms [1].
Earth's energy budget [2].
