Research Note: A Personal Satellite Starts With Four Problems
Published June 2026
Boundary
CosmosExplore treats the personal satellite path as a hobby and learning path, not a commercial spaceflight business. The first practical target is not a private rocket or a public service. It is a small, source-backed mission question: can a compliant object in low Earth orbit send a verified message that can be received, logged, and checked from the ground?
Four Problems
Transmission. A LEO message is only useful if the signal path is legal, identifiable, and verifiable. That means ground pass windows, a ground segment, data integrity, and frequency authorization come before any radio design.
Access to orbit. The default access path is compliant rideshare, hosted payload, or an educational/non-profit program. Self-developed orbital launch is outside this hobby path because public safety, range, vehicle, licensing, and liability burdens are not small just because the payload is small.
Maintenance. A small spacecraft still needs power, thermal limits, onboard computing, safe mode, and a disposal plan. "Small" reduces scale; it does not remove mission responsibility.
Control and recovery. For a first LEO hobby mission, recovery should mean recoverable data and state, not catching the spacecraft. Command uplink and attitude control are safety boundaries, not casual features.

Model Rule
The first CosmosExplore personal-satellite model should be a boundary graph, not a shopping list. Every node must answer one of three questions: what problem is this, what authority or safety boundary constrains it, and what evidence would make the next step more responsible?
