The Einstein Probe (EP) mission is a small scientific satellite dedicated to time-domain high-energy astrophysics. It aims at discovering transients and monitoring variable objects in 0.5-4 keV X-rays, for which it will employ a large instantaneous field-of-view (60°×60°, or ~1 steradian), along with moderate spatial resolution (FWHM ~5arcmin) and energy resolution. It will also carry a follow-up observation X-ray telescope with a smaller field-of-view (1°×1°) — capable of much larger light-collecting power and better energy resolution than the main survey telescope. Public transient alerts will also be issued rapidly, in order to trigger multi-wavelength follow-up observations from the world-wide community. Its wide-field imaging capability is achieved by using established technology of novel micro-pore “lobster-eye” optics, thereby offering unprecedentedly high sensitivity and large Grasp superseding previous and existing X-ray all-sky monitors and survey missions.
Einstein Probe has been selected as one of the candidate missions for advanced studies under the pilot space science programme of the Chinese Academy of Sciences.
