If we decide in the future to create sustainable habitats and ecosystems beyond Earth, enlarging our environmental responsibilities, then science will have a critical role to play. As the cost of access to space continues to fall, a fresh look at the research agenda for creating sustainable habitats and ecosystems is timely and necessary. We encourage contributions on all aspects of either local terraforming or global terraforming on or beyond Earth, including planetary atmospheres, climate modeling and climate feedbacks, monitoring of climate change beyond Earth, spacecraft data analysis, hydrology, soil/regolith composition, soil and regolith characterization and remediation for biological suitability, biogeochemistry, in-situ resource utilization for environmental control and life-support, oxygen production, ecology, and space physics, as well as the exploration and distribution of terraforming-relevant resources. Submissions on technologies and techniques that support applied astrobiology goals are particularly encouraged.
