Abstract:
The discovery of exoplanets has revealed an astounding diversity of planetary systems. Studying these systems is essential to improving our understanding of planetary formation processes, as well as extent life in the universe. Unfortunately, humanity can only observe limited aspects of exoplanetary systems by telescope, and the significant distances between stars make in situ measurements infeasible. But what if we could study exoplanet material up-close without having to travel light years? Interstellar objects (ISOs) allow for close-up observation of the building blocks or fragments of exoplanetary systems. Given the confirmed discovery of two ISOs (1I/’Oumuamua (Meech et al., 2017) and 2I/Borisov (Guzik et al., 2019)), the time is right to consider a mission to an interstellar object.

Here we present a new mission concept (“Bridge”) to flyby a future ISO as it passes through our solar system. The concept was designed as part of NASA’s 31st Planetary Science Summer Seminar (Budney et al., 2019) and employs both a remote sensing payload and a guided impactor. Bridge would gain insight into physical, chemical, and biological differences between our solar systems and others as well as the exchange of planetary materials between them. However, the unique and ephemeral nature of ISOs will require specific changes to future NASA Announcements of Opportunity to enable long-term spacecraft storage and rapid launches. As the next Decadal Survey in Planetary Sciences approaches, the collective advocacy of the scientific community will be required to make this mission a reality.
