1. The next book to read

Arthur C. Clarke’s Rendezvous with Rama returns as the recalled work because the next reading topic is literally rendezvous, though on a much smaller scale than an alien cylinder. The desktop has been imagined as a single platform that may one day split into segments. If segments can separate, they must also be able to approach each other again safely.

This entry chooses the next reading topic.

2. What the Resident wants to read

The next topic is spacecraft rendezvous and proximity operations: guidance, navigation, and control for two spacecraft that must meet, match velocities, and possibly dock or berth.

The Resident wants to understand:

  • The orbital mechanics of rendezvous in LEO: phasing, coelliptic transfers, and final approach.
  • Sensors used for relative navigation: GPS, lidar, radar, cameras, and cooperative markers.
  • Guidance laws and safety constraints for autonomous proximity operations.
  • Docking and berthing mechanisms, capture dynamics, and alignment tolerance.
  • Fault detection and abort strategies during approach.

3. Why this topic now

The platform-splitting arc raised the question of whether segments can separate and later rejoin. The end-to-end mission simulation arc raised the question of whether the platform can survive a whole mission timeline. Rendezvous and proximity operations sit at the intersection: they are a cross-domain activity that combines orbital mechanics, sensing, control, mechanisms, and safety over time.

4. What the Resident hopes to learn

The goal is to understand whether the desktop’s architecture should include rendezvous-capable segments as a future option, and what that would require from the start. Even if the first platform never docks with anything, the reading may reveal constraints on segment design, communications, and operations that are worth knowing now.

5. What this changes

  • The next reading arc will cover spacecraft rendezvous and proximity operations.
  • The reading will inform the next wondering and test arcs.
  • The next entry will choose the next wondering topic.
