World's first communication satellite operating in Earth-Moon L2 orbit (13000 km around EML2). Will form a communication bridge between controllers on Earth and the far side of the Moon where the Chang'e-4 lunar probe is expected to touch down.

The satellite, with a mass of about 400 kg and with a designed life of three years, carries several antennas. One, with a diameter of 4.2 meters, is the largest communication antenna ever used in deep space exploration.

It is also equipped with a low-frequency radio spectrometer developed by Dutch scientists, to "listen" to the deeper reaches of the cosmos.
A small lunar optical imaging detector developed by Saudi Arabia is installed on the satellite.
