"Capturing 'Oumuamua: The Quest for Interstellar Visitors"

A proposal has been published for a mission to send a spacecraft to study future interstellar objects passing through our Solar System, acknowledging that it will be a long time before we visit other star systems. The paper explores the practicality of catching up with an interstellar object, considering the most suitable instruments for such a job, and estimates that the preparation of such a spacecraft and placing it in orbit would cost less than a billion dollars.
