Fenix Space Flies Tow-Launch Prototype

Fenix Space is one step closer to leaving the world behind.

The CA-based launch startup completed a week-long testing campaign of its Fenix alpha prototype launch vehicle, validating the launcher’s ability to take off and land—without the use of a launch pad.

Hitchhiker’s guide: Fenix Space is hoping to offer customers an alternative to vertical launch at a time when the nation’s spaceports are becoming increasingly congested. Its launch system is designed to reach orbit by first gliding behind a tow aircraft, then detaching and propelling itself the rest of the way.

Over four flight tests, Fenix demonstrated its ability to separate from its ride in the sky and perform autonomous flight maneuvers using a proprietary GNC software and avionics package that will one-day fly on the full-sized Fenix 1.0 vehicle.

Demanding supply: US orbital attempts more than doubled between 2022 and 2025—yet American launchers still primarily rely on the same two spaceports that have served the nation since the ‘60s.

The DoD in particular is increasingly anxious about the concentration of the launch market—both in the number of companies that can reach orbit, and the number of available launch pads for vertical lift launchers. In January, the commanders of US military ranges highlighted the looming capacity issue at vertical launch sites on the coasts.

Fenix’s solution has the potential to provide a new launch supply, not limited by the availability of launch pads. The company’s horizontal-lift approach means it can take off and land from standard runways, and the DoD is actively supporting the development and testing effort. 

“Tow launch allows use of existing runways and reusable aviation assets which significantly lowers costs and enables dedicated launch-on-demand with maximum flexibility and safety,” Fenix CEO Jason Lee told Payload via email. 

What’s next: Fenix expects commercial launch operations to begin in 2028. The company’s long term vision is to develop a system that can fly multiple times per day and access SSO, but early iterations will focus on hypersonic testing and delivering small payloads to LEO, according to Lee.
