The Einstein Probe (EP) is a x-ray space telescope mission by Chinese Academy of Sciences (CAS) in partnership with ESA and the Max Planck Institute for Extraterrestrial Physics (MPE) dedicated to time-domain high-energy astrophysics.[1][2] The primary goals are "to discover high-energy transients and monitor variable objects".[3] It will carry two instruments: the Wide-field X-ray Telescope (WXT) and the Follow-up X-ray Telescope (FXT).[4]
FXT has optics adopted from eROSITA, "the mirror module consists of 54 nested Wolter mirrors with a focal length of 1600 mm and an effective area of greater than 300 cm2 at 1.5 keV."[4] WXT has a new optics design, called "lobster-eye", that has wider field of view.[2][4] "Lobster-eye" optics was first tested by by the Lobster Eye Imager for Astronomy (LEIA) mission, launched in 2022.[2][5]
The probe weights 1450 kg and is 3-by-3.4 metres.[2]
EP is planned to be launched in January 2024 by Chang Zheng rocket from the Xichang Satellite Launch Centre in China, and will be placed to low Earth orbit.[2]
