The European System Providing Refueling Infrastructure and Telecommunications (ESPRIT) is a planned module of the Lunar Gateway. It will provide refueling through additional xenon and hydrazine capacity for use in the Power and Propulsion Element's ion engines and hydrazine thrusters. It will also provide additional communications equipment, a habitation area, and storage. It will have a launch mass of approximately , a length of , and a diameter of . ESA awarded two parallel design studies for ESPRIT, one mostly led by Airbus in partnership with Comex and OHB and one led by Thales Alenia Space. The construction of the module was approved in November 2019. On 14 October 2020, Thales Alenia Space announced that they had been selected by ESA to build the ESPRIT module. The module is currently slated to launch as a co-manifested payload on Artemis 5 in 2028. 1.5 tons of cargo will be packed inside the module for launch. Configuration The ESPRIT module will consist of two parts, the Halo Lunar Communication System (HLCS) and the ESPRIT Refueling Module (ERM). Halo Lunar Communication System (HLCS) The Halo Lunar Communication System (HLCS) will provide communications for the station, allowing it to transmit data to and receive data from other spacecraft on and around the Moon. It will launch in 2024 pre-attached to the HALO module, for which Thales has separately been awarded a contract by NASA to construct its hull and micrometeoroid protection. The HLCS will measure in both length and width, have a mass of , and feature two dish antennas. These will allow HLCS to achieve a data rate of up to 25Mbps. Because of its two dishes, the system will be able to communicate with two different targets (including spacecraft landing on the Moon or operating around Gateway) at once in S- or K-band radio frequencies. ESPRIT Refueling Module (ERM) The ESPRIT Refueling Module (ERM) will contain the propellant tanks, docking ports, and a small windowed habitation corridor. The interior of the module will primarily be used for storage, although it will feature one workstation for astronaut use and six windows. The workstation and windows will be useful for photographing the lunar surface, controlling Canadarm3, and monitoring docking spacecraft. The module features two docking ports, meaning that once it docks to the HALO module, resupply craft and other vessels can dock to ESPRIT. These can include future propellant tankers to further refuel Gateway
