TLDR
The Laser Ranging Interferometer (LRI) instrument on the GRACE Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km.Abstract:
The Laser Ranging Interferometer (LRI) instrument on the Gravity Recovery and Climate Experiment (GRACE) Follow-On mission has provided the first laser interferometric range measurements between remote spacecraft, separated by approximately 220 km. Autonomous controls that lock the laser frequency to a cavity reference and establish the 5 degrees of freedom two-way laser link between remote spacecraft succeeded on the first attempt. Active beam pointing based on differential wave front sensing compensates spacecraft attitude fluctuations. The LRI has operated continuously without breaks in phase tracking for more than 50 days, and has shown biased range measurements similar to the primary ranging instrument based on microwaves, but with much less noise at a level of 1 nm/sqrt[Hz] at Fourier frequencies above 100 mHz.read more

Hopes and concerns for astronomy of satellite constellations
TL;DR: The launch of the first several hundred out of 12,000 planned Starlink satellites heralds the arrival of the era of ultra-large satellite constellations if it will bring new opportunities or insurmountable challenges to astronomy will probably depend on whether the observations in space or from the surface of the Earth as mentioned in this paper.
