The out-of-this-world hype cycle describes expectations and realities for extra-terrestrial resource production. Triggered by a technological innovation cluster in communication/automation/transport for the space industries, it inspires visions of prospecting and inter-planetary travel for economic gains. Visionary narratives are founded on (1) techno-futurism, a linear process of capital accumulation based on innovation; (2) techno-optimism, the belief that innovation will solve modern-day challenges without impacting consumption-based lifestyles; and (3) expansion of the resource base for economic development. We use a constructivist approach to scrutinise the opportunities for, and impediments to, off-Earth extraction through economic, political, sociological, legal, humanities, geological and engineering philosophies. Visionaries elevate the terrestrial activity of mining to the extra-terrestrial environment in a fantastical Martianist narrative while a counter-Martianist narrative simplifies extra-terrestrial prospecting and extractive challenges. The infancy of prospecting and limited engagement with the realities of terrestrial mining practice suggest that off-Earth extraction is a distant prospect. We conclude that expanding industrial activity by outsourcing of raw materials production is inhibited by the Terrestrial actor. Debates about out-of-this-world hype, the limiting factors to access raw materials beyond the Earth, and an immature (high-risk) safety culture for off-Earth extraction, reveal the imperative for multi-actor transformative behavioural change.

超凡脱俗的炒作周期描述了对地外资源生产的期望和现实。由航天工业的通信/自动化/运输技术创新集群触发，它激发了勘探和星际旅行以获得经济利益的愿景。有远见的叙述建立在 (1) 技术未来主义，一种基于创新的资本积累线性过程；(2) 技术乐观主义，相信创新将解决现代挑战而不影响以消费为基础的生活方式；（三）扩大经济发展的资源基础。我们采用建构主义方法，通过经济、政治、社会学、法律、人文、地质和工程哲学，审视地球外开采的机会和障碍。有远见的人在奇幻的火星主义叙事中将陆地采矿活动提升到地外环境，而反火星主义叙事则简化了地外勘探和开采挑战。勘探的起步阶段和对陆地采矿实践现实的有限参与表明，地外开采是一个遥远的前景。我们得出的结论是，通过原材料生产外包来扩大工业活动受到陆地参与者的抑制。关于地球外的炒作、获取地球以外原材料的限制因素以及地球外开采的不成熟（高风险）安全文化的辩论，揭示了多参与者变革性行为改变的必要性。
