The moon will get its first mobile phone network next year, enabling high-definition streaming from the lunar landscape back to earth, part of a project to back the first privately funded moon mission.

Vodafone Germany, network equipment maker Nokia and carmaker Audi said on Tuesday they were working together to support the mission, 50 years after the first Nasa astronauts walked on the moon.

Vodafone said it had appointed Nokia as its technology partner to develop a space-grade network which would be a small piece of hardware weighing less than a bag of sugar.

The companies are working with Berlin-based company PTScientists on the project, with a launch scheduled in 2019 from Cape Canaveral on a SpaceX Falcon 9 rocket, Vodafone said.

"This project involves a radically innovative approach to the development of mobile network infrastructure," Vodafone Germany chief executive Hannes Ametsreiter said.

One executive involved said the decision to build a 4G network rather a state-of-the-art 5G network was taken because the next generation networks remain in the testing and trial stage and are not stable enough to ensure they would work from the lunar surface.
