The Chang'e-4 mission will help illuminate some of the most shadowy secrets of our nearby neighbour, after landing on the far side of the world.
No spacecraft has made such a journey onto the distant part of the Moon. Doing so is difficult because it means venturing to a part of the Moon that is largely unknown to us, since we can never see its far side from Earth.
As well as the audacious landing on the planet, it will carry a range of scientific experiments. Perhaps most intriguingly of them all is a big container that includes seeds and insect eggs and hence create living things that will have been born on the Moon.
