暗宇宙探测器（DUNE）是一个宽视场成像任务概念，其主要目标是以前所未有的精度研究暗能量和暗物质。为此，DUNE针对弱引力透镜进行了优化，并使用了互补的宇宙学探测，如重子振荡、综合萨克斯-沃尔夫效应和星团计数。直接的附加目标涉及星系的演化，要用突破性的统计学来研究，银河系和附近星系的详细结构，以及地球质量行星的人口统计学。DUNE是一个中型任务，由一个1.2米的望远镜组成，设计用于在一个可见光波段和三个近红外波段（1deg2视场）进行全天调查，这将为天文学留下独特的遗产。DUNE已与SPACE共同被选中用于欧空局评估阶段，这导致了欧几里得合并任务概念。
The Dark UNiverse Explorer (DUNE) is a wide-field imaging mission concept whose primary goal is the study of dark energy and dark matter with unprecedented precision. To this end, DUNE is optimised for weak gravitational lensing, and also uses complementary cosmological probes, such as baryonic oscillations, the integrated Sachs-Wolf effect, and cluster counts. Immediate additional goals concern the evolution of galaxies, to be studied with groundbreaking statistics, the detailed structure of the Milky Way and nearby galaxies, and the demographics of Earth-mass planets. DUNE is a medium class mission consisting of a 1.2m telescope designed to carry out an all-sky survey in one visible and three NIR bands (1deg2 field-of-view) which will form a unique legacy for astronomy. DUNE has been selected jointly with SPACE for an ESA Assessment phase which has led to the Euclid merged mission concept.
