Organism/Organic Exposure to Orbital Stresses (ARC00XX220)
Research Area:
Species Studied
Scientific Name: Bacillus subtilis Species: Microbe
Scientific Name: Halorubrum chaoviatoris Species: Microbe

The overall goal of the O/OREOS mission is to demonstrate capability to conduct low-cost science experiments on autonomous nanosatellites in space in support of the Astrobiology Small Payloads program under the Planetary Science Division of the Science Mission Directorate at NASA’s Headquarters. Scientists will apply the knowledge they gain from O/OREOS to plan future experiments in the space environment to study how exposure to space changes organic molecules and biology. These experiments will help answer Astrobiology’s fundamental questions on the origin, evolution, and distribution of life in the universe.

NASA’s Astrobiology Program studies the origin, evolution, distribution, and future of life in the universe. The O/OREOS mission will demonstrate new technological capabilities that can advance scientists’ efforts in the field of Astrobiology research. Specifically, O/OREOS will demonstrate the ability of the low-cost nanosatellite platform to provide scientists with meaningful information about organisms and organic materials they expect to find in space.
