DSLWP A1 [HIT]
DSLWP A1 and A2 (Discovering the Sky at Longest Wavelengths Pathfinder) or Longjiang 1 and 2 are two identical Chinese lunar microsatellites mission to perform ultra long-wave astronomical observations developped at the Harbin Institute of Technology (HIT).
The 45 kg micro-satellites are to be launched piggy-back with Queqiao (Chang'e 4 Relay, but are to insert them by themselves into a 200 km × 9000 km lunar orbits. The satellites are three-axis stabilized and carry a radio-astronomy payload featuring two linear polarization antennas mounted along and normal to the flight direction, which uses the moon as a shield to avoid radio emmanations from earth. Additionally, the satellites carry a King Abdulaziz City for Science and Technology (KACST) developed micro-optical camera and a amateur radio communications system.
Longjiang 1 apparently apparently had issues on 21 May and remained initially in earth orbit.
Longjiang 2 successfully entered lunar orbit.
