Coauthors
Abstract	The High Energy cosmic-Radiation Detection (HERD) facility is one of several space astronomy payloads of the cosmic lighthouse program onboard China's Space Station, which is planned for operation starting around 2020-2025 for about 10 years. The main scientific objectives of HERD are indirect dark matter search, precise cosmic ray spectrum and composition measurements up to the knee energy, and high energy gamma-ray monitoring and survey. HERD is composed of a 3-D cubic calorimeter (CALO) surrounded by microstrip silicon trackers (STKs) from five sides except the bottom. CALO is made of about 10,000 cubes of LYSO crystals, corresponding to about 55 radiation lengths and 3 nuclear interaction lengths, respectively. The STK microstrips of seven X-Y layers are sandwiched with tungsten converters to make precise directional measurements of incoming electrons and gamma-rays. All STKs will also be used for measuring the charge and incoming directions of cosmic rays, as well as identifying back scattered tracks. With this design, HERD can achieve the following performance: energy resolution of 1% for electrons and gamma-rays beyond 100 GeV, 20% for protons from 100 GeV to 1 PeV; electron/proton separation power better than 1/100,000; effective geometrical factors of >3 m^2sr for electron and diffuse gamma-rays, >2.5 m^2sr for cosmic ray nuclei. R&D is under way for reading out the LYSO signals with optical fiber coupled to image intensified CCD and the beam test for the prototype of CALO made of LYSO crystals will take place in November 2015 at CERN.

Abstract	In this talk, I will summarize China's programs of high energy astrophysics in space. The approved missions are the Aark MAtter Particle Detecion Experiment (DAMPE) satellite for launch in the end of 2015, the Hard X-ray Modulation Telescope (HXMT) satellite mission for launch in 2016, the dedicated gamma-ray burst polarization expariment POLAR on China's spacelab for launch in 2016, the multiwavelength gamma-ray burst satellite mission SVOM for launch before 2022. Several missions are under study and will also be presented: the Einstein Probe (An X-ray Losbter Eye) satellite planned for launch around 2020, the X-ray Timing and Polarization (XTP) observatory planned for launch around 2020-2025, the X-ray All-Sky Monitor (XASM) and Neutron-star Extreme Astrophysics and Technology Exploration Research (NEATER) experiments onboard China's spacestation for launch around 2020, and the High Energy cosmic-Radiation Detection (HERD) facility onboard China's spacestation for launch between 2020-2025.
