Summary

This video from the French YouTube channel ‘Les Dossiers de l’Espace’ explores the emerging field of interstellar objects, focusing on the challenges and strategies for intercepting them. It begins by recounting the discovery of ‘Oumuamua in 2017 and the more recent comet Borisov in 2019, highlighting their significance as the first known visitors from outside our solar system. The video explains how these objects are detected, emphasizing the role of surveys like Pan-STARRS and the upcoming LSST. It discusses the scientific value of studying such objects, as they offer a unique glimpse into other planetary systems. The main focus is on the technical difficulties of sending a probe to intercept these fast-moving objects, given their late detection. Several mission concepts are presented, including a proposed mission to rendezvous with ‘Oumuamua in 2049 and a cubesat mission to Borisov. The video also covers the idea of a rapid-response mission like the Comet Interceptor, which would wait in space for a suitable target. It concludes by noting that the 2020s promise significant advances in this new field of astronomy.
