DSLWP-B’s journey to the Moon: part I
As you may well know, on May 20 a CZ-4C rocket launched from Xichang, China, to deliver Queqiao, the Chang’e 4 relay satellite, to the Moon. Queqiao is a communications relay satellite designed to orbit the L2 point of the Earth-Moon system, supporting the future Chang’e 4 rover
that will land on the far side of the Moon. From the L2 point, Queqiao
has a good view of both the Earth and the far side of the Moon.
This launch was shared by the DSLWP-A and -B
microsatellites, also called Longjiang 1 and 2. These two satellites
are designed to be put on a 200 x 9000km lunar orbit and their main
scientific mission is a proof of concept of the Discovering the Sky at Longest Wavelengths experiment, a radioastronomy HF interferometer that uses the Moon as a shield from Earth’s interferences.
