The model accommodates current activities and published positions, and increases involvement by allocating accountability for necessary professional and administrative activities. It coordinates messaging and other outreach functions to improve brand management. It increases sustainability by balancing volunteer workload. And it provides an open-ended structure that can be modified gracefully as needs, focus, and context evolve. Over the past 20 years, Space Architecture has attained some early signs of legitimacy as a discipline: an active, global community of practicing and publishing professionals; university degree programs; a draft undergraduate curriculum; and formal committee establishment within multiple professional organizations. However, the nascent field has few outlets for expression in built architecture, which exacerbates other challenges the field is experiencing in adolescence: obtaining recognition and inclusion as a unique contributor by the established aerospace profession; organizing and managing outreach by volunteers; striking a balance between setting admittance or performance credentials and attaining a critical mass of members; and knowing what to do, beyond sharing common interests, to actually increase the market demand for space architecture.

In order, we present a survey of distinct proposed concepts, reasonable performance parameter ranges for the missions of interest, configuration complications introduced by large aerobrakes, preliminary design and analysis of one concept and a feasible orbital assembly scenario, and assessment of relevant technology development programs.

The ocean-world science puzzle – which may reveal whether life is widespread in the cosmos, why it exists where it does, and how it originates – can only be solved by exploring all of them. Potential life in these places could not have shared our origins, yet these worlds contain the only evidence about life that we can touch, essentially forever. Thus, their exploration has existential significance. Planning a multiworld exploration campaign would be a multi-generational undertaking. The technical challenges are diverse and formidable, far harder than at Mars: missions to the Jovian and Saturnian ocean worlds are severely power-limited; trip times can be more than a decade. And the science targets are global-scale oceans beneath kilometers of cryogenic ice. Today, we lack the instrumentation, subsystems, and machine-intelligence technologies needed. A systematic OWEP (ocean worlds exploration program) strategy can make most effective use of funding and time. The three priority ocean-world targets are Europa at Jupiter, and Enceladus and Titan at Saturn. Five hypothetical programmatic scenarios are compared to the default case. A coherent OWEP should have several parts: first, dedicated continuous investment in enabling technologies; and second, two directed-purpose, medium-class (∼$1B) missions per decade that conduct pivotal investigations on a documented roadmap. A robust OWEP would cost about 1/40th more per year than NASA's current budget.
