BLITS-M (Ball Lens In The Space) retroreflector satellite is an improved version of the BLITS satellite.

BLITS-M is a 220 mm diameter glass sphere made of an inner and outer spherical body made from glass of different densities. It has a mass of 16.7 kg

The purpose of the mission is experimental verification of the spherical glass retroreflector satellite concept as well as obtaining SLR data for solution of scientific problems in geophysics, geodynamics, and relativity by millimeter and submillimeter accuracy SLR measurements. It will be used to increase the accuracy of the GLONASS satellite navigation system.
