China's Chang'e 6 mission to the moon was launched today.
The spacecraft and mission are very similar to Chang'e 5, which brought lunar rock samples back to earth in 2020, except that the Chang'e 6 landing site is on the far side of the moon (43.0°S 154.0°W).
Comms will take place via the Queqiao-2 relay satellite, which was launched on March 20 and is in an elliptical lunar orbit of 200×16,000 km at 62.4° inclination.
Mission time: 53 days

There is interest in exploring this south polar region due to the possibility of water ice. Also, the region could contain material ejected from the lunar mantle, which can provide insights into the history of the Earth-moon system.

The lander includes a coring drill and a robotic arm to collect samples.
There is no rover, although the mission carries a few other instruments.
The solar powered lander has to finish its mission in 14 earth-days.

Robotic landing on the moon has turned out to be lot harder than we thought, as evident from the poor success rate in such missions over the past few years. See table below.

in reply to AkaSci 🛰️ • • •The Chang'e 6 mission is expected to return lunar samples to earth 53 days after launch.
The lander is powered by solar cells (not an RTG as used by Chang'e 4 which also landed on the far side of the moon). Hence, it is expected to complete its surface mission during the lunar day. We can expect the landing to occur around May 29, since the Sun will rise at the landing site around then, as shown in the graph below of the elevation of the Sun at the site.
