Carbon-Free Satellite Launch for Zero Emission Payload Delivery

Green Launch uses light-gas propulsion powered by hydrogen and oxygen gas propellant rather than conventional rocket fuel systems associated with carbon-heavy emissions. According to the company, the primary byproduct is water vapor, supporting a zero carbon emission launch model. This approach is designed for customers who want cleaner payload delivery without giving up high-velocity performance for sub-orbital or orbital missions.

Green Launch supports several payload categories, including satellites, orbital supplies, propellant for space depots, sub-orbital research payloads, atmospheric sampling instruments, and hypersonic test articles. The platform is aimed at aerospace and defense organizations, scientific research groups, and satellite manufacturers that need responsive access to high-altitude or orbital environments.

Yes. Green Launch states that its system is being developed to deliver satellites and supplies to low Earth orbit using hydrogen cannon technology. The company positions this service as a lower-cost alternative to traditional launch methods, with a target delivery cost of $100 per pound and a rapid logistics model for time-sensitive orbital missions.

Yes. Sub-orbital payload delivery is one of Green Launch's active service areas. The company has performed launch series focused on atmospheric sampling and high-altitude missions, including a vertical launch that accelerated a projectile to more than Mach 3 and sent it into the stratosphere. These missions support research, testing, and technology validation objectives.

Green Launch reports demonstrated projectile launch velocities up to 2.97 kilometers per second, or about Mach 9, in testing. The company has also achieved vertical launch velocities exceeding Mach 3. These performance levels are important for customers pursuing hypersonic testing, upper-atmosphere access, and future orbital delivery applications requiring very high-speed deployment.

The service is designed for aerospace and defense organizations, scientific research institutions, and satellite manufacturers. It is especially relevant for missions that need lower-cost launch access, high-speed testing, atmospheric data collection, or responsive orbital logistics. Customers evaluating alternatives to conventional rockets may find the platform useful for both experimental and operational payload programs.

Green Launch supports research missions through sub-orbital delivery and atmospheric sampling services, including access to the mesosphere and ionosphere for scientific study. These capabilities can help climatologists and other researchers gather data from regions that are difficult to reach with conventional methods. The company has also identified atmospheric sampling as a near-term application for its launch technology.

Green Launch was founded in 2017 and lists 9 years in business in the provided company information. Since then, the company has advanced its light-gas propulsion platform through multiple milestones, including an initial testing contract with Yuma Proving Ground, successful horizontal test firings, and a first vertical light-gas launch for space access in 2022.
