- Earths stratosphere is similar to the surface of Mars: rarified air which is dry, cold, and irradiated. E-MIST is a balloon payload that has 4 independently rotating skewers that hold known quantities of spore-forming bacteria isolated from spacecraft assembly facilities at NASA. Knowing the survival profile of microbes in the stratosphere can uniquely contribute to NASA Planetary Protection for Mars.Objectives 1. Collect environmental data in the stratosphere to understand factors impacting microbial survival. 2. Determine of surviving microbes (compared to starting quantities). 3. Examine microbial DNA mutations induced by stratosphere exposure.
