Roman 简述

Roman 将凭借其宽广的视场（field of view）和先进的光学设计（optical design），在可见光至近红外（near-infrared）波段扫描大片天区。该任务将提供关键见解，有助于揭示暗能量（dark energy）和暗物质（dark matter）的本质，并发现新的系外行星（exoplanet）。

Roman will scan a large patch of the sky in visible to near-infrared light, with its wide field of view and advanced optical design. The mission will provide key insights that will help reveal the nature of dark energy and dark matter and find new exoplanets.

为了实现其科学目标，Roman 配备了一面 2.4 m 的主镜（primary mirror）以及两台仪器：宽视场仪器（WFI）和一台日冕仪技术验证器。

To achieve its science goals, Roman is equipped with a primary mirror of 2.4 m and two instruments: the Wide Field Instrument (WFI) and a Coronagraph Instrument technology demonstrator.

Roman 是由美国国家航天局（NASA）主导的任务，欧洲空间局（ESA）作为机会任务参与其中，提供科学专业知识和指导，以最大化该任务的科学回报。ESA 还通过其深空（deep space）地面站（ground station）网络提供必要的硬件和通信支持。

Roman is a NASA-led mission to which ESA contributes as a Mission of Opportunity, providing scientific expertise and guidance to maximise the mission's scientific return. ESA also provides essential hardware and communications support through its deep-space ground station network.
