Relais satellite for Chinese Chang'E4 lunar mission successfully launched


The relais satellite for the Chinese lunar mission Chang'E4 was successfully launched on May 21, 2018. Chang'E4 itself is foreseen to be launched in December this year and then fly to and land on the far side of the Moon. The relais satellite is needed for communication with the lander and its scientific payload. The Extraterrestrial Physics Division developed and built a radiation monitor which is part of the payload and is currently being tested together with the lander in Beijing.

There's a short article about it in Nature:
