Selection of the Apex bus
On June 22, the Pasadena‑based company Sophia Space announced that it will use the Apex bus to build its inaugural orbital computing node. The bus, already employed in several satellite projects, will host the Thermal Integrated LEO system designed to manage heat dissipation in low‑Earth orbit environments.
Purpose of the demonstration
The objective is to prove that high‑performance data processing can be performed directly in orbit, reducing reliance on ground‑based servers. The module will be tested in a low‑Earth orbit where thermal stresses are particularly demanding.
Technical specifications
- Form factor: compact, compatible with the standard Apex bus
- Computing power: multiple teraflops for AI and image‑processing workloads
- Cooling: integrated thermal solution tailored for LEO conditions
Future outlook
The flight demonstration is scheduled for the second quarter of 2027. A successful outcome could pave the way for broader adoption of on‑orbit computing platforms, especially for real‑time processing of large data volumes.
