| Three-Body Computing ConstellationADA Space (国星宇航) | LandSpace (蓝箭航天) | Supplier | Launch capacity Zhuque-2E Y4 launch on October 14, 2026 delivered the eight ADA Space Xingsuan group-02 satellites, identified by the launch provider as Star Era 39 and 44 through 50. Details & project milestonesZhuque-2E Y4 launch on October 14, 2026 delivered the eight ADA Space Xingsuan group-02 satellites, identified by the launch provider as Star Era 39 and 44 through 50. Successful launch and orbit delivery are confirmed. Contract value and procurement terms are not disclosed; planned in-orbit technology verification is not a completed demonstration. Additional evidence for this same role: https://changan.xiancity.cn/system/2026/10/20/031273140.shtml. The later October 20, 2026 tracking report describes the same October 14 launch of eight ADA Space satellites, also called Xingsuan group-02. The primary release does not link this launch to Oriental Tiansuan’s Mingzhu plan. That unsupported project association is replaced by the existing Three-Body/Xingsuan project link. Launch delivery is established, not completed computing validation. Disclosed buyer: Not disclosed. Associated organization: ADA Space (国星宇航). Three-Body Computing Constellation: Satellites launched Next project milestone: Publish group-02 commissioning and onboard computing results. No dated result is established. This is a project target, not a supplier delivery commitment. Evidence checked 27 Oct 2026. | Role confirmedSource ↗ |

Technical specifications retain the source’s original units and evidence status. Hardware counts, compute rates and power are not equivalent; launched hardware does not establish demonstrated performance. Supplier counts include suppliers and hosts only, reflect current filters and cover this directory, not the entire market. “No record” means no disclosure captured; it does not mean the work is unawarded. Latest developments use source dates, not routine review or collection dates.
