我们描述的科学动机，使命的概念和仪器的空间，在ESA宇宙愿景2015- 2025规划周期的第一次呼叫中，提出了一项M级使命，用于概念研究。太空计划旨在通过拍摄近红外光谱和测量超过5亿个星系在0 <z<2下降到托亚布~23，位于天空3πsr上方。此外，SPACE还将瞄准更小的天区，对托亚布~26和2 <z< 10 +的数百万个星系进行深光谱调查。由于天空背景高出10500倍，这些目标是地面观测无法达到的（参见例如Aldering，LBNL报告编号LBNL-51157，2001）。为了实现主要的科学目标，空间站将使用一个直径为1.5米的里奇-克雷蒂安望远镜，该望远镜配备了一套数字微镜装置阵列，覆盖0.4平方度的总视场，并将执行大规模多路复用多目标光谱学（例如，每次指向6000个目标），光谱分辨率为R~400，以及衍射限制成像，连续覆盖范围为0.8至1.8 μm。由于空间探测器的深度、红移范围、体积覆盖范围和光谱质量，它将以独特的灵敏度揭示大多数基本宇宙学特征，包括密度涨落及其周转的功率谱。空间探测器还将通过测量物质和辐射解耦时留下的重子声学振荡，对暗能量状态方程参数及其演化施加高精度约束，宇宙学超新星的距离-光度关系、宇宙膨胀率的演化、宇宙大尺度结构的增长率和高Z星系团。来自SPACEmission的数据集将代表整个天文学界的长期遗产，其数据将在未来许多年内被挖掘。
We describe the scientific motivations, the mission concept and the instrumentation ofSPACE, a class-M mission proposed for concept study at the first call of the ESACosmic-Vision 2015–2025planning cycle.SPACEaims to produce the largest three-dimensional evolutionary map of the Universe over the past 10 billion years by taking near-IR spectra and measuring redshifts for more than half a billion galaxies at 0 <z< 2 down toAB~23 over 3πsr of the sky. In addition,SPACEwill also target a smaller sky field, performing a deep spectroscopic survey of millions of galaxies toAB~26 and at 2 <z< 10 +. These goals are unreachable with ground-based observations due to the ≈500 times higher sky background (see e.g. Aldering, LBNL report number LBNL-51157, 2001). To achieve the main science objectives,SPACEwill use a 1.5 m diameter Ritchey-Chretien telescope equipped with a set of arrays of Digital Micro-mirror Devices covering a total field of view of 0.4 deg2, and will perform large-multiplexing multi-object spectroscopy (e.g. ≈6000 targets per pointing) at a spectral resolution of R~400 as well as diffraction-limited imaging with continuous coverage from 0.8 to 1.8 μm. Owing to the depth, redshift range, volume coverage and quality of its spectra,SPACEwill reveal with unique sensitivity most of the fundamental cosmological signatures, including the power spectrum of density fluctuations and its turnover.SPACEwill also place high accuracy constraints on the dark energy equation of state parameter and its evolution by measuring the baryonic acoustic oscillations imprinted when matter and radiation decoupled, the distance-luminosity relation of cosmological supernovae, the evolution of the cosmic expansion rate, the growth rate of cosmic large-scale structure, and high-zgalaxy clusters. The datasets from theSPACEmission will represent a long lasting legacy for the whole astronomical community whose data will be mined for many years to come.
