LUNAR PATHFINDER

The First Commercial Communications Services

Lunar Pathfinder will be the first spacecraft in orbit around the Moon to commercially offer communication services to Lunar assets, whether coming from companies, governments, universities, non-profit organisations or individuals, the aim is to offer a high-performance, competitively priced option to relay communications between the Earth and Lunar assets.

Data-relay communications

Lunar Pathfinder offers 2 simultaneous channels of communication to lunar assets: 1 in S-band and 1 in UHF. Communications are then relayed back to Earth ground station in X-band.

Lunar Pathfinder offers various levels of service packages depending on the lunar asset location and payload capabilities.

Lunar Pathfinder will be fully operational for commercial services operations by mid to late 2023, following a service-restricted period of commissioning and demonstration, for an operational lifetime of 8 years.

Mission orbit offering periodic coverage of the whole Moon surface, privileging southern hemisphere missions

Lunar Pathfinder will operate in an Elliptical Lunar Frozen Orbit (ELFO), for an operational lifetime of over 8 years.

This orbit favours a long duration coverage of the lunar southern hemisphere, understood to be more attractive for early lunar missions. It covers the far side of the Moon and benefits from long access times to Earth to relay back customers’ data.

Ground segment

Depending on the service need, Lunar Pathfinder will use several ground stations, appropriately distributed around the Earth.

The baseline ground station for the mission is the 32 meter dish antenna owned by Goonhilly Earth Station (GES), in Cornwall, UK. located at 50.05°N 5.18°W.

The service is currently designed to pass all payload data through a single ground station in the early stages of the mission.
