Investment in spacefaring enterprises must offer transformative solutions to Earth-based challenges. Providing for the future health of our home planet is possibly the greatest return on investment. Therefore, ensuring that the large costs of astronautics also yield benefits on Earth is critical. The goal of space bioprocess engineering is the design, realization and management of biologically driven technologies for supporting off-world human exploration. Here, we outline several technologies with high dual-use potential, argue that continued investment in such technologies is justified, and offer insight into specific research and development strategies that will increase sociological, political and technological benefits for sustainable development on Earth.

The integration of biology and spacefaring has led to the development of three interrelated fields: Astrobiology, Bioastronautics, and Space Bioprocess Engineering. Astrobiology is concerned with the study of the origin, evolution, distribution, and future of life in the universe, while Bioastronautics focuses on the effects of spaceflight on biological systems, including human physiology and psychology. Space Bioprocess Engineering, on the other hand, deals with the design, deployment, and management of biotechnology for human exploration. This paper highlights the unique contributions of each field and outlines opportunities for biologists to engage in these exciting avenues of research. By providing a clear overview of the major fields of biology and spacefaring, this paper serves as a valuable resource for scientists and researchers interested in exploring the integration of these disciplines.
