  The discovery of `Oumuamua and CNEOS 2014-01-08 allowed for a calibration of
the impact rate of interstellar objects. We propose a new telescope in lunar
orbit to study in real-time interstellar meteoroid impacts and to serve as a
laboratory for hypervelocity collisions. We show that a telescope with diameter
$D_a \gtrsim 2 \mathrm{\; m}$ would be capable of detecting $\gtrsim 1$
interstellar meteoroid impacts (among hundreds of Solar System meteoroid
impacts) per year. For each meteoroid, measurements of the reflected sunlight
and shadow, as well as the impact's optical flash and crater, would allow for
the determination of the 3D velocity, mass, density, and composition, as well
as the radiative efficiency.
