China has officially begun a new round of lunar exploration and will send the first-ever lunar probe to the dark side of the moon in 2018 as part of its ambitious space program.
The far side of the moon is never visible to Earth because of gravitational forces and has never been explored by humans. Chang'e-4 will be the first mission in human history to embark on this expedition.
China achieved its first soft-landing on the moon with Chang'e-3 in December 2013, and it is still sending messages back to Earth.
China became the third country, after the US and the former Soviet Union, to land a probe on lunar soil when it's Chang'e-3 probe reached the moon in 2013.
