How to Catch a Comet That Hasn't Been Discovered Yet

There’s been a lot of speculation recently about interstellar visitor 3I/ATLAS - much of which is probably caused by low quality data given that we have to observe it from either Earth, or in some case Mars. In either case it’s much further away that what would be the ideal. But that might not be the case for a future interstellar object. The European Space Agency (ESA) is planning a mission that could potentially visit a new interstellar visitor, or a comet that is making its first pass into the inner solar system. But, given the constraints of the mission, any such potential target object would have to meet a string of conditions. A new paper by lead Professor Colin Snodgrass of the University of Edinburgh of his colleagues, discusses what those conditions are, and assesses the likelihood that we’ll find a good candidate within a reasonable time of the mission's launch.
