描述了继即将到来的雨燕任务之后的下一代伽马射线爆发（GRB）任务。拟议的高能 X 射线成像巡天望远镜 EXIST 将产生有限的（实用的）GRB 触发灵敏度、宽带光谱和时间响应以及宽视场的空间分辨率。它将提供 GLAST 在 GeV 能量下检测到的伽玛暴的高分辨率光谱和位置。与下一代任务 Constellation-X、NGST 和 LISA 以及光学巡天 (LSST) 望远镜一起，EXIST 将使伽玛暴能够用作早期宇宙和第一代恒星的探测器。单独的 EXIST 就可以给出约 10-50 英寸的位置（长或短伽玛暴）、滞后的近似红移，并限制喷流、孤儿余辉、中微子和 SGR 的物理特性。
A next generation Gamma Ray Burst (GRB) mission to follow the upcoming Swift mission is described. The proposed Energetic X‐ray Imaging Survey Telescope, EXIST, would yield the limiting (practical) GRB trigger sensitivity, broad‐band spectral and temporal response, and spatial resolution over a wide field. It would provide high resolution spectra and locations for GRBs detected at GeV energies with GLAST. Together with the next generation missions Constellation‐X, NGST and LISA and optical‐survey (LSST) telescopes, EXIST would enable GRBs to be used as probes of the early universe and the first generation of stars. EXIST alone would give ∼10–50″ positions (long or short GRBs), approximate redshifts from lags, and constrain physics of jets, orphan afterglows, neutrinos and SGRs.
