SpaceX, best known for its rockets and spacecraft, is building its own particle accelerator in a surprising expansion beyond its core launch business. The move signals the company's growing ambitions in advanced technology development and could serve multiple purposes related to its space exploration mission.

Particle accelerators can be used for a wide range of applications beyond fundamental physics research, including testing how materials and electronics withstand radiation exposure in space, developing advanced propulsion concepts, or studying particle interactions relevant to deep-space travel. For SpaceX, which is actively developing its Starship vehicle for missions to Mars, understanding and mitigating the effects of cosmic radiation on both hardware and human passengers is a critical challenge. Building an in-house particle accelerator would give the company a powerful tool for conducting this research on its own terms and timeline.
