Abstract

Microorganisms may exist in Low Earth Orbit both from terrestrial sources, and potentially, from extraterrestrial origins. A simple, low cost method for in-situ detection is proposed, suitable for CubeSat and similar micro and nano-satellite implementation. A block of silica aerogel, similar to that used on the highly successful Stardust mission, is used as a collection medium. Edge-wise UV illumination by a LED array, and orthogonal optical emission detection by a photodetector array, is used for identification. The detection process is on-going, and no sample return is required. Potential terrestrial background sources and missions of extraterrestrial opportunity are discussed.
