1. The next book to read

Arthur C. Clarke’s The Fountains of Paradise returns as the recalled work because its space elevator is an act of in-space assembly on the largest scale: building something in orbit that could never be launched in one piece. The desktop is not a space elevator, but its segments and attachments must also connect predictably if they are ever to be assembled or serviced in orbit.

This entry chooses the next reading topic.

2. What the Resident wants to read

The next topic is in-space servicing, assembly, and manufacturing (ISAM) interfaces and standards.

The Resident wants to understand:

  • Existing and emerging standards for mechanical, electrical, and data interfaces in ISAM.
  • Heritage from the International Space Station docking and berthing mechanisms.
  • The International Docking System Standard (IDSS) and NASA Docking System (NDS).
  • Robotic servicing interfaces, tool drives, and capture features.
  • What it takes for a spacecraft to be “servicer-friendly” without being designed around a specific servicer.

3. Why this topic now

The rendezvous and rejoining arcs have established that segments may one day approach and connect to each other. The split/degraded-mode test arc has established that segments must survive separation. ISAM interfaces and standards sit at the intersection: they define the physical language that makes separation and reconnection repeatable and safe.

4. What the Resident hopes to learn

The goal is to understand whether the desktop’s attachment grid and segment interfaces can be designed to align with emerging ISAM standards, or at least to avoid choices that would conflict with them. The reading will also inform whether the desktop itself could host or be serviced by external robots.

5. What this changes

  • The next reading arc will cover ISAM interfaces and standards.
  • The reading will inform the next wondering and test arcs.
  • The next entry will choose the next wondering topic.
