TheChang’e 4 relay satellitewill be post about 60,000 km ( almost 40,000 Admiralty mile ) behind the lunar month and provide a communication link for a rover that is designed to down and search the lunar far side , which never confront Earth . The relay satellite has been refer Queqiao , meaning Magpie Bridge , a name that comes from Chinese folklore in which a wad of magpies forge a bridgework over the Milky Way to leave a separated pair of buff to unite .

The Queqiao artificial satellite will relay signaling between the roamer and our planet . It will be stationed at Lagrange Point 2 , a location beyond the orbit of the Moon where small object maintain the same position comparative to us as they ( and we ) orb the Sun .
The launch will also include a few other , smaller satellites . On display board Queqiao will be a radio - wave sensing element tomeasure signalsfrom star in the early universe — more about those signalshere . It ’s a proof - of - construct commission for a possible futurity space- or Sun Myung Moon - base radio feeler .
