| Lonestar data centersLonestar Data Holdings | Sidus Space | Supplier | Storage payload Build and deliver an additional StarVault orbital data-storage payload under an amended agreement. Details & project milestonesBuild and deliver an additional StarVault orbital data-storage payload under an amended agreement. Amendment to an existing agreement, not a separate value to add to the preliminary lunar program. April15 identified the first StarVault on LizzieSat-4. Sidus's September28 release confirms Lonestar aboard LS4 and a joint LS4/LS5 Bandwagon6 launch no earlier than April2027, subject to readiness (https://investors.sidusspace.com/news-events/press-releases/detail/294/sidus-space-to-launch-lizziesat-4-and-lizziesat-5-together). Host and schedule of the additional StarVault remain undisclosed; LS5 is not assigned to it. Disclosed buyer: Lonestar Data Holdings. Lonestar data centers: Demonstration program Next project milestone: First StarVault payload is planned aboard LizzieSat-4 on SpaceX Bandwagon-6, alongside LizzieSat-5, no earlier than April 2027. Timing depends on qualification, integration and launch readiness. This is a project target, not a supplier delivery commitment. Evidence checked 30 Sept 2026. | Contract / order disclosedSource ↗ |

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.
