摘要
由 Nancy Grace Roman Space Telescope 执行的深层太空全景红外线观测将构成数十年间的基础天文基础设施。在本白皮书中，我们提出了一条具体且可行的路径，通过 Cycle 1 开始，以 的分辨率实现整个天空的成像，并在正式任务期间扩展至超广阔的覆盖范围。该初次观测将达到 AB 幅度 (5)，并最大化与同步观测仪器之间的协同作用，同时保留相当大的时间用于其他宏伟的罗马计划。我们概述了代表性的排程方案以及一个 Cycle 1 项目的示例，该项目三倍地扩大了早期 Roman-LSST 的重叠范围，并交付高价值社区数据产品，如 LSST 强制 photometry、联合 \textit{Gaia}-Roman 星测量以及Galactic 亚结构、强透镜和其他稀有系统的目录。Cycle 1 项目将为最终的全景罗马观测奠定基础，同时也能交付高影响力的早期科学。我们邀请广大社区参与塑造和实施该初始项目以及长期愿景中全景罗马观测的工作。
