Not to be confused with Einstein Observatory.

The Einstein Probe (EP) is an 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 the Lobster Eye Imager for Astronomy (LEIA) mission, launched in 2022.[2][5][6]

The probe weights 1450 kg and is 3-by-3.4 metres.[2]

EP is scheduled for launch on 9 January 2024, at 07:20 UTC by a Long March 2C rocket from the Xichang Satellite Launch Centre in China, and will be placed in low Earth orbit.[2]
