Will help astronomers see deeper into supermassive black holes, obtain views of collapsed stars and better measure the influence of dark energy on the cosmos. The craft's flight path will naturally shift due to the influence of the moon's gravity over the course of the five-year mission.

Control over the satellite was lost in Jan 2019, maybe after cosmic radiation accumulated in the instrument
