| Altair-Next GenMarlan Space | MaiaSpace | Supplier | Launch Preferred launch services for Altair-Next Gen as MaiaSpace services become commercially available. Details & project milestonesPreferred launch services for Altair-Next Gen as MaiaSpace services become commercially available. The announcement says preferred launch partner, not a contract or reserved capacity; the initial October launch provider is not named. Disclosed buyer: Not disclosed. Associated organization: Marlan Space. Altair-Next Gen: Operator-reported onboard AI workload Next project milestone: Further commissioning and measured application-service results for Altair1, plus delivery dates for subsequent satellites. This is a project target, not a supplier delivery commitment. Evidence checked 25 Sept 2026. | Role confirmedSource ↗ |
| No tracked project linkInstitute for Q-shu Pioneers of Space (iQPS) | MaiaSpace | Supplier | Launch Basic agreement for Maia launch services for iQPS QPS-SAR satellites from 2029, covering dedicated, shared and auxiliary-payload opportunities across multiple orbits. Details & project milestonesBasic agreement for Maia launch services for iQPS QPS-SAR satellites from 2029, covering dedicated, shared and auxiliary-payload opportunities across multiple orbits. iQPS explicitly describes a basic agreement. MaiaSpace also calls it a commercial agreement or contract, but neither body discloses a firm launch count, satellite allocation, price, exact mission dates or binding booking terms. Launch services start from 2029 as a plan. The September 10 announcement date is not asserted to be the signing day. MaiaSpace launcher capacity, optional Colibri stage and future launch cadence are design or roadmap claims. Disclosed buyer: Institute for Q-shu Pioneers of Space (iQPS). Evidence checked 11 Oct 2026. | Preliminary agreementSource ↗ |
| No tracked project linkRIDE! space | MaiaSpace | Supplier | Launch integration Commercial arrangement for integration of compatible auxiliary payloads alongside dedicated Maia primary missions, subject to mission requirements. Details & project milestonesCommercial arrangement for integration of compatible auxiliary payloads alongside dedicated Maia primary missions, subject to mission requirements. No price, allocation, firm reserved capacity, mission count or launch date disclosed. Compatibility remains mission-dependent; the inaugural Maia flight is still future. Disclosed buyer: RIDE! space. Evidence checked 12 Oct 2026. | Contract / order disclosedSource ↗ |
| No tracked project linkLoft Orbital | MaiaSpace | Supplier | Launch capacity Launch of multiple Loft Orbital missions from the Guiana Space Centre, starting in 2028, under the contract described by MaiaSpace. Details & project milestonesLaunch of multiple Loft Orbital missions from the Guiana Space Centre, starting in 2028, under the contract described by MaiaSpace. The source dateline is Paris, July 8, 2026; the webpage heading and current publication timestamp are July 15. Announced date refers to the dated release, not a separately proven contract-signature date. Number of missions, price, exact legal purchasing entity, individual launch dates and spacecraft/project allocations are undisclosed. The 2028 start remains prospective, and launcher specifications do not establish delivered launch performance. Disclosed buyer: Loft Orbital.

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.
