Space expansionism, science fiction, and space developments are intimately linked. SF from Verne, Wells, and others inspires space expansionists, and SF is shaped by space discoveries. SF makes space expansionism seem plausible but is often unbound by scientific possibility. An assessment of building block, life-engineering, and transformative technologies reveals that large-scale space activities are becoming more feasible, but creating enclosed ecologies, geo-engineering and terraforming remain doubtful. Anticipating the consequences of new technologies (technology assessment) remains difficult. Technology governance is plagued by recalcitrant syndromes. Theorists of catastrophic and existential risk view space colonization as necessary to escape a long list of possible major calamities (including hostile artificial superintelligence and misused genetic engineering for improved humans, called transhumanism). Human survival increasingly depends on competent futurism and social capacities to steer technology with reversals, regulations, and relinquishments, but these are difficult to establish and maintain. Can vital arrangements of restraint survive large-scale space expansion?

Large-scale space projects rely on a thorough Assembly, Integration, and Verification (AIV) process to provide the upmost reliability to spacecraft. While this has not traditionally been the case with CubeSats, their increasing role in space science and technology has led to new verification approaches, including in educational CubeSats. This work describes the integration and verification approach for ISTSat-1, which is an educational CubeSat from the Instituto Superior Técnico in Portugal that partially discards the typical stage-gate approach to spacecraft development in favor of a more iterative approach, allowing for the system-level verification of unfinished prototypes. Early verification included software functional testing on a flatsat model, thermal vacuum and vibration testing on a battery model, ionizing radiation testing on the on-board computer, and non-ionizing radiation (EMC) testing on all subsystems. The testing of functional prototypes at an early development stage led to uncovering system-level errors that would typically require hardware redesign at a later project stage. The team considers the approach to be useful for educational projects that employ a small, co-located team with low non-recurring engineering costs.
