The NISAR mission launched on July 30, 2025 to explore Earth's most complex natural processes. NISAR's science orbit is defined within a tightly-constrained diamond corridor which is achieved through the frequent execution of maneuvers, up to five per week. This maneuver frequency enables a fixed standard workday schedule with simpler planning. This paper discusses how frequent maneuver designs and automation lead to a sustainable orbit maintenance strategy. This paper also presents NISAR's two-maneuver design approach for mitigating conjunction risks while minimizing excursions from the diamond, an approach that is automated and decoupled from routine orbit maintenance.
