Paper Abstract

A “formation flight astronomical survey telescope” (FFAST) is a new project that will cover a large sky area in hard X-ray. In particular, it will focus on the energy range up to 80 keV. It consists of two small satellites that will go in a formation flight. One is an X-ray telescope satellite carrying a “super mirror” and the other is a detector satellite carrying an SDCCD. Two satellites are put into a low earth orbit. They are in a formation flight with a separation of 20 m. Since two satellites are put into Keplerian orbit, the observation direction is moving the sky rather than pointing to a fixed direction. This project will survey a large sky area at hard X-ray region to study the evolution of the universe.
