Harbin Institute of Technology previously developed the Longjiang-1 and Longjiang-2 small satellites that piggybacked on the Queqiao lunar relay satellite to support the Chang’e-4 lunar far side landing mission.

GeneralCapabilityValue 4.0Jun 9, 2023China’s first stackable satellite reaches orbit on solid rocket launch

The King Abdulaziz City for Science & Technology provided a small camera that flew on the Longjiang-2 (DSLWP-B) lunar microsatellite launched as part of the Chang’e-4 lunar far side landing mission.

RelationshipsCapabilityPlanValue 4.0Dec 30, 2022China looks to build space partnerships with Gulf nations

Longjiang-2 (DSLWP-B) is a 47-kilogram microsatellite launched in May 2018 alongside the Queqiao relay satellite for the Chang’e-4 lunar far side mission.

CapabilityPlanValue 4.0Jul 12, 2019China set to carry out controlled deorbiting of Tiangong-2 space lab

Longjiang-2 returned an image of the total solar eclipse over the Pacific using a small 'Inory Eye' camera earlier 2019-07.

CapabilityValue 4.0Jul 12, 2019China set to carry out controlled deorbiting of Tiangong-2 space lab

The Chang’e-4 mission component Longjiang-2 is a 45-kilogram microsatellite that launched with Queqiao and operates in an elliptical lunar orbit.

CapabilityValue 5.0Feb 11, 2019Chang’e-4 powers down for second lunar night

Longjiang-2 (DSLWP-B) successfully entered an elliptical lunar orbit using its own propulsion on 2018-05-25.

CapabilityPlanValue 4.0Jun 14, 2018Chang’e-4 relay satellite enters halo orbit around Earth-Moon L2, microsatellite in lunar orbit

Longjiang-2 was intended to test space-based interferometry in conjunction with Longjiang-1.

CapabilityPlanValue 3.0Jun 14, 2018Chang’e-4 relay satellite enters halo orbit around Earth-Moon L2, microsatellite in lunar orbit

The May launch will also carry two microsatellites named Longjiang-1 and Longjiang-2 developed by the Harbin Institute of Technology.

PlanCapabilityValue 3.5May 14, 2018China preparing to launch Chang’e-4 relay satellite May 21
