The concept of the Antimatter Driven Sail (ADS) has been examined in three major areas: Mission Architecture, Subsystem Technologies, and a Technology Roadmap. The Mission Architecture effort has focused on developing an integrated systems model to evaluate the performance of the entire spacecraft for a mission. The Subsystem Technologies investigation examined 1) the fundamental reactions between the antiprotons and the sail material and the subsequent momentum transfer, 2) a concept for storing antihydrogen at high densities, and 3) an entirely new concept for electrical power production. The new electrical‐power concept may have applicability to nearer‐term space missions as a power supply if the availability of antiprotons becomes common. In developing the Technology Roadmap, we examined the potential 1) for using recent developments in antiproton storage and antihydrogen formation to create a path to ultra‐high density antihydrogen storage, and 2) for increasing production of antiprotons by modifying the existing Fermilab facility. Our system analysis indicates that a 10 kg instrument pay load could be sent to 250 AU in 10 years using 30 milligrams of antihydrogen. This amount of antimatter is clearly within the production potential of the US within the next 40 years using currently accepted accelerator technologies. Major aspects of the architecture remain to be investigated but the first‐cut assessment of the mission profile, the subsystem technologies, and the technology development path have all been identified. The antimatter driven sail may in‐fact allow humanity to consider sending probes to the stars.
