Surrey Satellite Technology (SSTL) is designing a low cost 35 kilogram lunar communications satellite mission called DoT-4, targeted for a 2021 launch. DoT-4 aims to provide the communications relay back to Earth using the Goonhilly Deep Space Network, and will link up with a rover on the surface of the Moon. SSTL is currently in discussions with a number of parties for the lunar mission, and expects to disclose further information on mission partners and funding early in 2019.

DoT-4 aims to be the pre-cursor mission for a larger lunar communications satellite to follow in the 2023 timeframe which will have the potential for navigation services. SSTL’s ultimate aim is to launch a full constellation of lunar communications satellites offering full service capability to enable new and regular opportunities for science and exploration and economic development of the space environment beyond Earth’s orbit.

DoT-4 is one of a series of Demonstration of Technology (DoT) missions that SSTL is planning to launch over the coming years.
