The National Aeronautics and Space Administration’s (NASA) Great Observatories Maturation Program (GOMAP) will advance the science definition, technology, and workforce needed for the Habitable Worlds Observatory (HWO) with the goal of a phase A start by the end of the current decade. GOMAP offers long-term cost and schedule savings compared with the “technology readiness level (TRL) 6 by preliminary design review” paradigm historically adopted by large NASA missions. Many of the key technologies in the development queue for HWO require the combined activities of (1) facility and process development for validation of technologies at the scale required for HWO and (2) deployment in the “real-world” environment of mission integration and test prior to on-orbit operations. We present a concept for the SmallSat Technology Accelerated Maturation Platform (STAMP), an integrated facility, laboratory, and instrument prototype development program that could be supported through the GOMAP framework and applied to any of NASA’s future Great Observatories (FGOs). This brief describes the recommendation for the first entrant into this program, “SmallSat Technology Accelerated Maturation Platform-1 (STAMP-1),” an ESPA Grande-class mission advancing key technologies to enable the ultraviolet capabilities of HWO. STAMP-1 would advance new broadband optical coatings, high-sensitivity ultraviolet detector systems, and multi-object target selection technology to TRL 6 with a flight demonstration. STAMP-1 advances HWO technology on an accelerated timescale, building on current research opportunities in space and earth sciences (ROSES) strategic astrophysics technology (SAT) + astrophysics research and analysis (APRA) programs, reducing cost and schedule risk for HWO while conducting a compelling program of preparatory science and workforce development with direct benefits for HWO mission implementation in the 2030s.

SmallSat 技术加速成熟平台-1：一项旨在推进宜居世界观测站紫外线科学、劳动力和技术的提案


美国国家航空航天局 (NASA) 大型天文台成熟计划 (GOMAP) 将推进宜居世界天文台 (HWO) 所需的科学定义、技术和劳动力，目标是在本十年末启动 A 阶段。与 NASA 大型任务历史上采用的“通过初步设计审查达到技术准备级别 (TRL) 6”范式相比，GOMAP 可实现长期成本和进度节省。 HWO 开发队列中的许多关键技术需要结合以下活动：(1) 设施和流程开发，以按 HWO 所需的规模验证技术；(2) 在任务集成和部署的“现实世界”环境中部署在轨运行之前进行测试。我们提出了小型卫星技术加速成熟平台 (STAMP) 的概念，这是一个综合设施、实验室和仪器原型开发计划，可以通过 GOMAP 框架提供支持，并应用于 NASA 未来的任何大型天文台 (FGO)。本简报描述了对该计划的第一个参与者的建议，即“小卫星技术加速成熟平台-1 (STAMP-1)”，这是一项 ESPA Grande 级任务，旨在推进关键技术以实现 HWO 的紫外线能力。 STAMP-1 将通过飞行演示将新型宽带光学涂层、高灵敏度紫外线探测器系统和多物体目标选择技术提升至 TRL 6。 STAMP-1 以加速的时间尺度推进 HWO 技术，以当前空间与地球科学 (ROSES) 战略天体物理技术 (SAT) + 天体物理研究和分析 (APRA) 项目的研究机会为基础，降低 HWO 的成本和进度风险，同时开展引人注目的预备科学和劳动力发展计划，对 2030 年代 HWO 任务的实施有直接好处。
