该3.5米分块镜机器人空间望远镜任务为太阳系小天体与行星防御，结合地基中红外望远镜，利用CODES等系统开展小天体恢复、表征及轨道预测，评估其 hazard。
AI 中文摘要
基线0.2至1.5微米的观测台为近地天体及其他小天体提供快速响应天体测量、可见光与近红外分类、自转与相位曲线、天体恢复及长弧轨道改进。仪器研究还评估了至2.70微米的校准通量，目标为3.0微米的工作波段边缘。若热、探测器、冷却、质量、功率或成本约束要求，可正式将波段缩减至2.5微米作为工程退避方案。该3.5米分块镜机器人空间望远镜不携带中红外通道，地基中红外望远镜协同提供推断直径与反照率所需的热通量，而空间任务提供同期反射光测量与观测几何。该项目结合天体恢复、物理表征、轨道精化及基于协方差的 hazard assessment（此处保留英文专有名词），其CODES动力学系统与OGFinder-to-OpenOrb处理路径将测得的天体测量数据关联至可复现的轨道解与近距离接近预测。
英文摘要
The baseline 0.2--1.5 $μ$m observatory provides rapid-response astrometry, visible and near-infrared taxonomy, rotation and phase curves, recovery, and long-arc orbit improvement for near-Earth objects and other small bodies. The instrument study also evaluates calibrated throughput to 2.70 $μ$m with a 3.0 $μ$m operational band-edge goal. A reduction to 2.5 $μ$m remains the formal engineering off-ramp if thermal, detector, cooling, mass, power, or cost constraints require it. The 3.5-meter Segmented-Mirror Robotic Space Telescope does not carry a mid-infrared channel. Coordinated ground-based mid-infrared telescopes provide the thermal fluxes required to infer diameter and albedo, while the space mission supplies contemporaneous reflected-light measurements and observing geometry. The program combines recovery, physical characterization, orbit refinement, and covariance-based hazard assessment. Its CODES dynamics system and OGFinder-to-OpenOrb processing path connect measured astrometry to reproducible orbit solutions and close-approach predictions.
CommentsRevised to clarify the small-body science scope, expand prior-study attribution, and distinguish 3.5ST optical/NIR observations from targeted ground-based MIR follow-up
