  A rapid accumulation of observations and interpretation have followed in the
wake of 1I `Oumuamua's passage through the inner Solar System. We briefly
outline the consequences that this first detection of an interstellar asteroid
implies for the planet-forming process, and we assess the near-term prospects
for detecting and observing (both remotely and in situ) future Solar System
visitors of this type. Drawing on detailed heat-transfer calculations that take
both `Oumuamua's unusual shape and its chaotic tumbling into account, we affirm
that the lack of a detectable coma in deep images of the object very likely
arises from the presence of a radiation-modified coating of high molecular
weight material (rather than a refractory bulk composition). Assuming that
`Oumuamua is a typical representative of a larger population with a kinematic
distribution similar to Population I stars in the local galactic neighborhood,
we calculate expected arrival rates, impact parameters and velocities of
similar objects and assess their prospects for detection using operational and
forthcoming facilities. Using `Oumuamua as a proof-of-concept, we assess the
prospects for missions that intercept interstellar objects (ISOs) using
conventional chemical propulsion. Using a "launch on detection" paradigm, we
estimate wait times of order 10 years between favorable mission opportunities
with the detection capabilities of the Large-Scale Synoptic Survey Telescope
(LSST), a figure that will be refined as the population of interstellar
asteroids becomes observationally better constrained.
