| Lonestar data centersLonestar Data Holdings | Microchip Technology | Supplier | Processors / accelerators Microchip PolarFire system-on-chip running Linux for Lonestar's Freedom lunar data-center payload; the processor family is named in the October 2024 developer-network announcement. Details & project milestonesMicrochip PolarFire system-on-chip running Linux for Lonestar's Freedom lunar data-center payload; the processor family is named in the October 2024 developer-network announcement. The April 2024 release names Microchip as the RISC-V processor supplier; the October 22, 2024 developer-network release identifies the PolarFire SoC family (https://www.lonestarlunar.com/press-release/lonestar-unveils-lunar-developer-network). The purchasing party, exact part number, quantity, order value and commercial terms remain undisclosed. This historical Freedom hardware does not establish StarVault's configuration. Disclosed buyer: Not disclosed. Associated organization: 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 27 Sept 2026. | Role confirmedSource ↗ |
| Planetek AI-eXpressPlanetek Italia | Microchip Technology | Supplier | Processors / accelerators PolarFire SoC and VectorBlox acceleration IP were flown on earlier AI-eXpress missions in 2025 for onboard-computing validation and characterization. Details & project milestonesPolarFire SoC and VectorBlox acceleration IP were flown on earlier AI-eXpress missions in 2025 for onboard-computing validation and characterization. This is an explicitly identified program, hardware or research role. No legal procurement buyer, contract signature date, paid order, value or guaranteed service level is disclosed. The release does not allocate this configuration to AIX-1+; proposed integration into future D-Orbit avionics is a separate future scope. Radiation-hardness certification and achieved orbital throughput are not established. Disclosed buyer: Not disclosed. Associated organization: Planetek Italia. Planetek AI-eXpress: In-orbit operation demonstrated Next project milestone: No dated next mission milestone disclosed; continued application trials and platform development. This is a project target, not a supplier delivery commitment. Evidence checked 27 Sept 2026. | Role confirmedDisclosure date not suppliedSource ↗ |

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.
