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