论文摘要
探索冰巨星行星的关键是避免尖端技术。复杂性会产生延迟和财务障碍。可以及时推出简单的机器人侦察兵，以在2030年代初从木星助攻。 NASA对大型任务的预算的需求，例如火星样本返回，将不允许在短期内允许前往天王星和海王星的旗舰任务。冰巨头探索的科学目标可以通过一系列快速，简单，负担得起的（FSA）飞行器来实现。由轨迹和资金决定的节奏将发射单独的成本范围轨道和探针。将使用机会公告（AO）选择承包商。航天器技术进步的游行提供了希望和前进的道路。关键是要开始小，并保持负担得起。
The key to the exploration of the Ice Giant planets is avoiding cutting edge technology. Complexity produces delay and financial roadblocks. Simple robot scouts can be launched in time to utilize gravity assists from Jupiter in the early 2030s. Demands on NASA's budget from large missions, such as Mars sample return, will not allow Flagship missions to Uranus and Neptune in the near term. The science goals of Ice Giant exploration can be accomplished by a series of fast, simple, affordable (FSA) craft. Separate lines of cost-capped Orbiters and Probes would be launched at a cadence dictated by trajectories and funding. Contractors would be selected using competitive Announcements of Opportunity (AO). The march of progress in spacecraft technology offers hope and a path forward. The key is to start small and keep it affordable.
