Project Lyra explores the feasibility of sending spacecraft to interstellar objects like 1I/'Oumuamua and 2I/Borisov using current and near-future technology, aiming to gather close-range scientific data. The initiative has developed multiple mission concepts that could intercept these fast-moving visitors decades after their discovery.

Why it matters: Intercepting interstellar objects offers unprecedented opportunities to study material from beyond our solar system directly.

The big picture: Missions face extreme challenges due to high object velocities but can leverage gravitational assists and advanced propulsion to catch up.

Quick takeaway: Launch windows exist in the 2020s and 2030s with mission durations spanning 16–26 years, making such missions technologically feasible.

Commenters say: Enthusiasm centers on the scientific potential and innovative mission designs, while some express skepticism about costs and technical risks.
