OrcaSat

Demo-1, then Demo-2, on rockets. Then OrcaSat-1, a 1U CubeSat in low Earth orbit. It photographs its own deploy, and Earth. The dispenser is Horizon’s.

Later flights are go / no-go, not dates. 2028 is intent, not a contract. Longshot is a separate program. Neptune is not OrcaSat-5. Horizon does not operate launch vehicles.
