abstract = "{The Gravity Recovery And Climate Experiment (GRACE) Follow-On mission
was launched on May 22, 2018, to continue monitoring changes in
the gravity field of the Earth by measuring distance variations
between two spacecraft that fly 200 km apart in a low-Earth
polar orbit. The laser ranging interferometer (LRI), a
technology demonstrator onboard GRACE Follow-On, is the first of
its kind to perform interspacecraft ranging measurements and has
shown noise levels of 1 nm/Hz at 100 mHz and 200 pm/Hz at 5 Hz.
Its development was shared between parties in Germany and the
United States. A key optical component for the LRI's success is
the triple mirror assembly (TMA), which acts as a corner-cube
retroreflector and enables the laser link between the two
spacecraft. This paper presents the TMA design and
characterization from the unit level to measurements in orbit.
The in-orbit measurements furthermore provide the far-field
intensity distribution of the Gaussian beams exchanged between
the spacecraft after traveling 200 km. We address lessons
learned that have influenced the design of the next generations
of the LRI.}",
