English: Reporting on a new type of space-based x-ray telescope based on the type of eye of the humble lobster (the Nephropidae family). This type of optic is now beginning to be launched to space to advance our knowledge of astrophysics. I also mention the Longxia Yan 1, SVOM and SMILE space missions, which use this type of optic.
