1. The empathy box and the real one
Philip K. Dick’s Do Androids Dream of Electric Sheep? has a device called the empathy box, which lets people share a simulated experience. It is a strange, intimate piece of technology. The desktop’s attachments should feel like that: not generic boxes, but tools that extend what a person or organization can do. The first attachments define what the desktop is for.
Entry 185 defined the desktop as a LEO-hosted, power-rich, connected workstation. This entry lists the attachments that would make it useful from day one.
2. Attachment one: high-performance compute cluster
The most desktop-like attachment is a compute cluster. Not a single ruggedized computer, but a set of processors, GPUs, and storage that can run serious workloads: image processing, machine learning, simulation, encryption, or data analytics.
This is the attachment that justifies the power budget. A desktop without compute is just a power outlet in orbit.
3. Attachment two: high-rate communications
A desktop needs to talk. A high-rate communications attachment — phased array antennas, optical links, or a combination — gives the desktop the bandwidth to move data. Without it, the compute cluster grinds against its own storage limits.
This attachment also makes the desktop a relay. Other satellites, drones, or ground stations can route through it.
4. Attachment three: Earth and space sensors
A sensor suite — optical, radar, radio, or infrared — turns the desktop into an observation post. The difference from a normal remote-sensing satellite is that the desktop can process the data locally, task the sensors on demand, and combine the results with other attachments.
It can also point outward. Space situational awareness, astronomy, and asteroid tracking are natural desktop applications.
5. Attachment four: manufacturing workshop
The desktop has enough power and volume to host a real manufacturing workshop: 3D printers for polymers and metals, a small CNC mill, a robotic arm, and storage for feedstock and finished parts. This is the attachment that turns the desktop from a server into a factory.
Customers upload designs. The desktop makes parts. Visiting vehicles pick them up or install them elsewhere.
6. Attachment five: keeper tug
The desktop is big enough to host or dock a small keeper tug. The tug can inspect nearby satellites, retrieve small objects, move parts between nodes, or nudge debris. The desktop becomes the garage and control center for the tug.
This is the attachment that connects the desktop back to the keeper work from earlier entries.
7. What the first desktop looks like
A credible first desktop carries at least three of these: compute, communications, and sensors. Manufacturing and a keeper tug follow once the core is proven. The desktop is useful from the start, but it becomes more useful as attachments accumulate.
What this changes
- The five first desktop attachments are compute cluster, high-rate communications, sensors, manufacturing workshop, and keeper tug.
- Compute and communications are the core; sensors provide early revenue; manufacturing and tug provide long-term differentiation.
- The next leisure entry can estimate the desktop’s power budget.
