Spider是一个气球实验，将以约1°的分辨率测量大部分天空中宇宙微波背景的偏振。六个单色折射毫米波望远镜与天线耦合过渡边缘超导测辐射热计的大阵列将提供系统灵敏度分别为4.2和3.1 μKcmb/s在100和150 GHz。一个旋转的半波片将调制每个望远镜的偏振灵敏度，控制系统。在225 GHz和275 GHz工作的辐射热计阵列将允许消除极化的银河前景。在2010年从澳大利亚的爱丽丝泉开始的为期2-6天的首次飞行中，Spider将把50%的天空映射到一个必要的深度，以提高我们对再电离光学深度的认识。
Spider is a balloon-borne experiment that will measure the polarization of the Cosmic Microwave Background over a large fraction of a sky at ~ 1° resolution. Six monochromatic refracting millimeter-wave telescopes with large arrays of antenna-coupled transition-edge superconducting bolometers will provide system sensitivities of 4.2 and 3.1 μKcmb√s at 100 and 150 GHz, respectively. A rotating half-wave plate will modulate the polarization sensitivity of each telescope, controlling systematics. Bolometer arrays operating at 225 GHz and 275 GHz will allow removal of polarized galactic foregrounds. In a 2-6 day first flight from Alice Springs, Australia in 2010, Spider will map 50% of the sky to a depth necessary to improve our knowledge of the reionization optical depth by a large factor.
