Our take

Developing and operating satellites represents a significant challenge. Many organizations need accurate, space-based data but lack the resources or expertise to build their own spacecraft or manage the necessary ground systems and data processing.

To tackle this issue, Muon Space provides a service called Muon Halo. This allows customers to access satellite data without having to handle the technical details of satellite construction or operation. Muon offers end-to-end solutions, including building and launching satellites, managing operations, and processing collected data.

Muon has contracts with major customers like the US Air Force and US Space Force, and it is set to launch ten satellites between 2025 and 2026. With financial backing, the company is ready to expand its services and meet the growing demand for space-based solutions.
