ACES is intended to boost satellite payloads to geosynchronous orbit or, in the case of an interplanetary space probe, to or near to escape velocity. Other alternative uses include a proposal to provide in-space propellant depots in LEO or at L2 that could be used as way-stations for other rockets to stop and refuel on the way to beyond-LEO or interplanetary missions, and to provide the high-energy technical capacity for the cleanup of space debris.As of 2015, ULA announced conceptual plans to transition the Vulcan rocket to the ACES second stage after approximately 2023. Vulcan will initially launch with the Centaur upper stage, beginning with its first flight no earlier than 2019."@en }
