The previous decade saw the discovery of the first four known interstellar
objects due to advances in astronomical viewing equipment. Future sky surveys
with greater sensitivity will allow for more frequent detections of such
objects, including increasingly small objects. We consider the capabilities of
the Legacy Survey of Space and Time (LSST) of the Vera C. Rubin Observatory to
detect interstellar objects of small sizes during its period of operation over
the next decade. We use LSST's detection capabilities and simulate populations
of interstellar objects in the range of 1-50m in diameter to calculate the
expected number of small interstellar objects that will be detected. We use
previous detections of interstellar objects to calibrate our object density
estimates. We also consider the impact of the population's albedo on detection
rates by considering populations with two separate albedo distributions: a
constant albedo of 0.06 and an albedo distribution that resembles near earth
asteroids. We find that the number of detections increases with the diameter
over the range of diameters we consider. We estimate a detection rate of up to
a small ISO every two years of LSST's operation with an increase by a factor of
ten for future surveys that extend a magnitude deeper.Comment: 17 pages, 7 figure
