Commercial Lunar Mission Support Services
The Commercial Lunar Mission Support Services (CLMSS), also called Lunar Mission Support Services  (LMSS) is a collaboration between Surrey Satellite Technology Ltd (SSTL), Goonhilly Earth Station (GES) and the European Space Agency (ESA) to develop a lunar telecommunications and navigation infrastructure to support lunar scientific and economic development.
Dozens of different commercial, private and public missions to the Moon are planned for the coming decades, so the Commercial Lunar Mission Support Services (CLMSS) project intends to provide a sustainable communications and navigation infrastructure. The commercial collaboration includes an upgrade of the Goonhilly Earth Station for commercial cis-lunar telecommunications, and the development of their first orbiter called the Lunar Pathfinder that is proposed to be launched in 2022 or 2023. While the signed agreement covers missions to the Moon, there is the potential to apply a similar service for Mars in the future.
As of 2019, the Lunar Pathfinder orbiter is being offered to carry public and private instruments and CubeSats to an elliptical lunar orbit that would place an emphasis on covering the far side of the Moon and the South Pole–Aitken basin because of its potential lunar resources. The orbiter would be developed by Surrey Satellite Technology Ltd (SSTL), and launched in 2022 or 2023. The system envisioned would utilise international standardised protocols for interoperability and cross-support. It would have a capacity of up to 60 kilograms (130 lb) payload to lunar orbit, and function as a relay satellite for about 5 years.
