With Vera Rubin's Large Synoptic Survey Telescope coming online, we'll likely see many more of these. It seems like it would be very difficult to physically intercept any large percentage; what is the next best alternative to physical interception? Lasers? Masers? Comet trail sampling? Pre-staged interceptors?(Interstellar Interloper Interceptor? I'd be interested in entertaining the possibility)
