In science:

The scientific case and technical challenges of space-borne long-baseline FIR interferometry have been studied in the USA and in Europe involving tethered or free-flying 3-m class cold telescopes with adjustable spacing for good u-v plane coverage.
A Demonstration of Spectral and Spatial Interferometry at THz Frequencies
SOFIA is the world’s largest flying observatory, consisting of a 2.7 m (diameter) reflective telescope that was developed by Deutsches Zentrum fur Luft und-Raumfart (DLR) that resides in a heavily modified Boeing 747-SP aircraft provided by NASA.
Early Science Results from SOFIA, the World's Largest Airborne Observatory
For large baseline free-space interferometers, in which an integral truss is impractical, individual free-flying telescopes will have to do precision formation flying and accurate fringe tracking.
Does the Lunar Surface Still Offer Value As a Site for Astronomical Observatories?
Consequently, plans for such lunar polar telescopes require substantial survey work, perhaps from fly-over radar studies, low-light imaging, or actual visits with illumination in tow.
Does the Lunar Surface Still Offer Value As a Site for Astronomical Observatories?
It is noteworthy that lunar gravity, while small, would require support structure connecting a lunar telescope to the surface that is substantially stronger than that needed to connect a free-flying telescope at EL2 to its shield.
