  The earliest confirmed interstellar object, `Oumuamua, was discovered in the
Solar System by Pan-STARRS in 2017, allowing for a calibration of the abundance
of interstellar objects of its size $\sim 100\;$ m. This was followed by the
discovery of Borisov, which allowed for a similar calibration of its size $\sim
0.4 - 1 \mathrm{\; km}$. One would expect a much higher abundance of
significantly smaller interstellar objects, with some of them colliding with
Earth frequently enough to be noticeable. Based on the CNEOS catalog of bolide
events, we identified in 2019 the meteor detected at 2014-01-08 17:05:34 UTC as
originating from an unbound hyperbolic orbit with 99.999\% confidence. In 2022,
the U.S. Department of Defense has since verified that "the velocity estimate
reported to NASA is sufficiently accurate to indicate an interstellar
trajectory," making the object the first detected interstellar object and the
first detected interstellar meteor. Here, we discuss the dynamical and
compositional properties of CNEOS 2014-01-08, and describe our plan for an
expedition to retrieve meteoritic fragments from the ocean floor.
