Muon Space Officially Opens High-Mix Satellite Manufacturing Facility in San Jose

Muon Space announced the grand opening of its new advanced manufacturing facility in San Jose, California. The 130,000-square-foot facility significantly expands Muon’s manufacturing capacity and positions the company to meet growing demand for satellite constellations across national security, civil, and commercial markets.

Muon is hosting a ribbon-cutting ceremony to celebrate the new facility June 22 at 11:00 AM PDT. The ceremony features prominent speakers from across the public and private sectors, including Congressman Jimmy Panetta (CA-19); San Jose Mayor Matt Mahan; representatives from the office of U.S. Representative Sam Liccardo; Gabrielle Stevenson of the California Governor’s Office of Business and Economic Development; Robert Brose, Deputy Assistant Secretary of War for Space and Missile Defense; and Brian Collins, Executive Director of the Earth Fire Alliance, a key Muon customer and partner. Muon CEO Jonny Dyer is delivering the opening remarks before the ceremonial ribbon cutting.

“Muon’s Mission Foundry represents a fundamental shift in how constellations are built and scaled, and this facility is the engine behind it,” said Jonny Dyer, CEO of Muon Space. “It’s purpose-built for the speed, consistency, and volume that our customers in commercial, civil, and national security markets urgently need. And it’s designed to support many different mission types, from smaller satellites to large, high-capability spacecraft. Today we’re celebrating not just a new facility, but a new era of satellite production.”

Purpose-built for vertical integration and high-mix, high-rate production, the San Jose facility can support up to 500 satellites annually in the 100 kg to 1,500+ kg class. The site features 70,000 square feet of manufacturing space, including 30,000 square feet of cleanroom facilities across multiple cleanliness classifications – a tenfold expansion over Muon’s previous facility. Dedicated areas support spacecraft assembly, optical instrument integration, mission operations, and in-house propulsion system production and integration. A 300-kW onsite solar array powers the majority of facility operations, and the site meets UL 2050 security standards for defense programs. 

“We’ve always been a place where big ideas get built, and Muon Space choosing to scale here is the latest example of San Jose’s strength in advanced manufacturing," said San Jose Mayor Matt Mahan. “Muon’s new facility brings high-skilled jobs to San Jose and will power work that is mission critical for our community and many others, including wildfire detection and monitoring satellites.”

While today’s ceremony marks the facility’s official public opening, satellite production at the site was already underway prior to the event – a testament to Muon’s aggressive delivery schedule and the operational readiness of the new facility. The site is central to Muon’s broader scale-up strategy, supporting a growing roster of government and commercial customers and an accelerating launch cadence across defense, civil, and commercial missions. It also deepens Muon’s presence in the San Jose technology ecosystem.

Following the ribbon-cutting ceremony, guests including government officials, customers, partners, and members of the media will tour the facility, receiving a firsthand look at Muon's high-mix, high-rate production lines, cleanroom facilities, and vertically integrated manufacturing capabilities for flight-ready spacecraft.
