The commercial spaceflight industry is progressing rapidly. Yet, there is a lack of research theorising what the spatio-temporal contours of sustainability look like if the biosphere, along with its finite resources and limited ability to sustain continued population growth, constitutes a boundary that can be readily transcended. Informed by the concept of sustainable trajectory, this paper presents a conceptual model that extends the traditional spatial (e.g. national, global) and temporal (e.g. near future, intergenerational) scales that sustainability discourses in geography are typically predicated upon. We conducted a critical narrative literature review to analyse the implications of space tourism in the context of sustainable trajectory. Our analysis highlights deep tensions between the perspectives of sustainability typically promulgated in academic spheres and the path dependencies currently being formed by private spaceflight companies.
