摘要
SDSS-V 将是一项针对超过六百万个天体的全天空、多历元光谱巡天。它旨在解码银河系的历史、追踪化学元素的出现、揭示恒星的内部运作并研究行星的起源。它还将创建银河系与本地星系群中气体的积分视场光谱图，其规模比当前最先进水平大 1000 倍，且空间分辨率足以揭示星系生态系统的自调节机制。SDSS-V 将开创全天空的系统光谱监测，揭示从 20 分钟到 20 年尺度的变化。因此，该巡天将追踪宇宙中最明亮持久天体——星系中心成长中的大质量黑洞——的闪烁、耀发与剧烈转变。SDSS-V 的范围与灵活性在现有及未来光谱巡天中将是独一无二的：它是全天空的，在两个半球拥有匹配的巡天基础设施；它提供近红外与光学多目标光纤光谱，可快速重构以服务于高密度目标、机会目标与时间域监测；并提供光学、超宽场积分视场光谱。SDSS-V 的计划于 2020 年启动，将恰逢其时地倍增来自重大空间任务（如 TESS、Gaia、eROSITA）与地面项目的科学产出。SDSS-V 建立在 SDSS 二十五年来在数据分析、协作基础设施与成果交付方面进展的传承之上。该项目目前正在细化其科学范围、优化巡天策略，并开发基于 SDSS-IV 基础设施的新硬件。我们在此呈现这些进展的现状概述，以寻求建立我们的全球机构与个人成员联盟。
