SpaceTech 101: The Full Value Chain Behind the New Space Economy
Everything for beginner that do not know what it is
SpaceTech is simply the industry of building technologies that help humans access space, operate in space, and use space-based data or infrastructure to solve problems on Earth.
| Company | What they do |
|---|---|
| AAC Clyde Space | Builds small satellite components and complete small satellite missions. |
| GomSpace | Makes nanosatellite platforms and subsystems. |
| Blue Canyon Technologies | Builds small satellite buses and spacecraft systems. |
| Honeybee Robotics | Builds robotic systems and mechanisms for space missions. |
| Mynaric | Builds laser communication terminals for space and airborne networks. |
| CesiumAstro | Builds advanced phased-array communication payloads for satellites. |
| Pale Blue | Develops water-based propulsion systems for small satellites (University of Tokyo spinout building water-propellant thrusters). |
| Letara | Develops hybrid propulsion using plastic-based solid fuel and nitrous oxide, targeting safer, lower-cost propulsion. |
| AADYAH Aerospace | Provides satellite and launch-vehicle subsystems (onboard computers, reaction wheels, sun sensors, star trackers, avionics). |
A satellite is not just one machine. It is a bundle of subsystems: solar panels, batteries, sensors, cameras, antennas, propulsion, computers, thermal systems, navigation systems, and communication equipment. Satellite component companies make the building blocks that other companies use to assemble satellites or spacecraft.
Satellites can be used for communication, Earth observation, weather forecasting, navigation, scientific research, defense monitoring, or internet connectivity.
Launch providers take satellites, spacecraft, cargo, or scientific payloads from Earth into orbit.
Once a satellite is in orbit, it still needs to communicate with Earth. That communication happens through ground stations: antennas and infrastructure that send commands to satellites and receive data back.
Mission software helps companies design, simulate, launch, operate, monitor, and manage satellites. This layer can look more like enterprise SaaS than aerospace manufacturing
This is the part of SpaceTech that most normal consumers will actually experience: internet, phone connectivity, IoT connectivity, broadband, or communications where terrestrial networks are weak or unavailable.
Earth observation companies use satellites to capture images, radar data, climate data, weather data, or environmental information about Earth.
Raw satellite data is not useful by itself. Most customers do not want satellite images; they want answers.
As more satellites go into orbit, space becomes crowded. This layer tracks objects, predicts collision risks, and coordinates satellite movements.
Once there are thousands of satellites in orbit, companies will need services to move them, extend their lives, refuel them, repair them, or bring them safely down.
This is closely related to orbital logistics but more focused on maintaining or cleaning up space assets.
Some materials may be easier or better to make in space because of microgravity, vacuum conditions, and extreme temperature environments.
Satellites need power. Space stations, lunar bases, and orbital platforms will need even more power. This creates a new infrastructure layer.
Cislunar space means the region between Earth and the Moon. This market includes lunar landers, rovers, payload delivery, lunar communication, power, navigation, and eventually resource extraction.
