The stated end goal of the Moonlight project is to make it easier for institution and companies to build infrastructure (i.e. mining, utilities, power, etc.) on the Moon, culminating in a sustained long-term human presence.[4] LCNS is intended for enhancing efficiency and reducing costs of lunar operations.[3]ESA intends to work in partnership withNASA andJAXA in creating lasting telecommunications and navigation links with the moon,[5] involving the adoption of theLunaNet specifications.[6][3]
The communications relay satelliteLunar Pathfinder, set for launch in 2026,[7][8] will serve as a precursor to the full LCNS constellation. The complete constellation will consist of five lunar orbiters between 400 and 600 kg per satellite, launched in two separate stages.[9] One satellite will be focused on communications ("COMSAT") and four on navigation ("NAVSAT-1" to "NAVSAT-4").[3][10] The orbits of the LCNS satellites will be designed to prioritise coverage of thelunar south pole area.[3] The COMSAT satellite will have anorbital period of 12 hours and asemi-major axis of about 6,000 km. The NAVSAT satellites will have an orbital period of 24 hours and a semi-major axis of about 10,000 km. All LCNS satellites will be placed on Elliptical LunarFrozen Orbits (ELFOs) in order to keep a constanteccentricity,inclination, andargument of pericenter.[10]
In February 2023, ESA expressed interest in creating internationallunar timekeeping standards and stressed their importance for LCNS and similar projects.[16]
In June 2023, The first satnav receiver designed to operate in lunar orbit has been delivered toSSTL in the UK for integration aboard theLunar Pathfinder spacecraft.[17]
In October 2023, ESA launched "a competition for visionary business ideas" for how to use LCNS, and expects to offer contracts to develop such ideas.[4]
In November 2024, ESA officially commenced the LCNS programme at theInternational Astronautical Congress in Milan.[3] At this event, ESA signed a contract worth 123 million euro withTelespazio to manage the development of LCNS.[18]
In March 2025, Telespazio has awarded a contract toThales Alenia Space to build the four satellites and to develop elements of the system’s ground segment.[19] ESA andJAXA have signed a statement of intent detailing future cooperation within theLunaNet framework.[20] ESA has also selectedViasat to lead the lunar orbiting satellite communications portion of LCNS, alongsideTelespazio.[21] Viasat will design and develop the end-end service, covering the satellites, ground segments, and user terminals.[22]
In July 2025, two UK companies—SSTL andMDA Space UK—joined the Moonlight initiative to work with Viasat.[23]
In September 2025,Telespazio andispace signed a letter of intent to start collaborating on LCNS, possibly by using the ispace's flight-tested technology to transport the LCNS satellites into lunar orbit.[9]
