We present optimized observation schedules for a distributed configuration of the Remote Occulter Mission. Accounting for refueling rounds, we show that an Earth-orbiting Remote Occulter could enable up to 158 ground-based observations of 80 exoplanetary targets in a mission lifetime. We develop two target lists, provide exposure time estimates for each potential target star, present an analytic approach for determining target observability, and estimate the cost of station-keeping and retargeting maneuvers required to maintain such a mission. We optimize the mission observation schedule over these cost and science delivery estimates using deterministic and metaheuristic optimization methods with varying degrees of operator intervention and conclude by assessing mission profile sensitivity to both isolated and accumulated cost and design perturbations.

使用超大型望远镜工作的轨道恒星的系外行星成像调度优化

我们为远程掩星任务的分布式配置提出了优化的观测计划。考虑到加油回合,我们表明,在任务生命周期中,绕地球轨道的隐秘者可以对80个系外目标进行多达158个地面观测。我们制定了两个目标清单,为每个潜在目标恒星提供了曝光时间估算,提出了一种确定目标可观测性的分析方法,并估算了维持这种任务所需的站位维护和重新定向演习的成本。
