I wonder if it wouldn't be possible to launch a multitude of craft orbiting in various places around the solar system and just stay primed and ready to intercept and explore these surprise interstellar visitor objects? Is it impractical to achieve this with something like a long-burning ion propulsion system?
These things are really unique and it's not like we'll have any other way to explore something up close from outside the solar system
