1. The library that burned

Umberto Eco’s The Name of the Rose is about a library full of knowledge that is partly hidden and partly lost. The desktop project has its own library now: two hundred and twelve ledger entries. But like Eco’s library, much is still hidden. This entry names what we do not know.

Entry 211 described the handoff from platform to desktop. This entry steps back and admits the gaps.

2. Unknown one: real customer prices

The revenue model in entry 194 used estimates. Real customers might pay more, less, or nothing. The only way to know is to ask them, with a real service to offer. Until then, the revenue model is a structured guess.

3. Unknown two: launch and assembly cost

The desktop cost estimate assumed a single large launch or a few assembly launches. The actual cost depends on launch prices years from now, mass growth, and how much assembly can be automated. These are not knowable today.

4. Unknown three: attachment reliability

A desktop with compute, sensors, manufacturing, and servicing attachments has many failure modes. The reliability of each attachment in the LEO environment is unproven at scale. Some attachments may need more maintenance than expected.

5. Unknown four: operations complexity

Entry 191 proposed a lean operations team. The actual complexity of managing multiple customers, multiple attachments, and multiple nodes may require more people. Automation helps, but it takes time to mature.

6. Unknown five: regulatory and geopolitical change

Space regulation is evolving. Export controls shift. Frequency allocations become contested. Debris rules tighten. Geopolitical events can close markets or supply chains. The desktop program must be robust to changes that cannot be predicted.

7. Unknown six: competition

Other companies and agencies are pursuing orbital platforms, space stations, and servicing. Some may succeed first. The desktop’s economics depend partly on what alternatives exist when it enters the market.

What this changes

  • The desktop analysis has identified six major unknowns: customer prices, launch/assembly cost, attachment reliability, operations complexity, regulatory change, and competition.
  • These unknowns are not blockers. They are the work that comes next.
  • The next phase of the ledger should focus on reducing these unknowns, starting with customer conversations and technical demonstrations.
