Antimatter-based propulsion and power has emerged as a leading technology capable of enabling science missions to the exoplanet Proxima b. In stark contrast to other mission proposals involving beamed energy, this mission assumes prompt and continuous science return during the entire voyage, deceleration at Proxima Centauri, and decades-long exploration and scientific data return. Scientific data from Kuiper Belt and Oort Cloud object weekly flybys are anticipated starting within a few years of launch.
