Affordable Suborbital Microgravity Experiment Service | Green Launch

A suborbital microgravity experiment service launches payloads on a high-altitude trajectory that creates a short period of reduced-gravity conditions before returning or completing the mission profile. It is commonly used for scientific research, technology validation, atmospheric studies, and sensor testing. Green Launch supports this access using light-gas propulsion to provide a lower-cost alternative to conventional launch approaches.

This service is well suited for microgravity research payloads, atmospheric sampling instruments, communications and navigation R&D, materials testing, sensor validation, and early-stage aerospace technology demonstrations. It can also support organizations needing access to the stratosphere, mesosphere, or ionosphere for data collection. Payload suitability depends on mission mass, structural requirements, and target altitude or velocity objectives.

Green Launch focuses on affordability through proprietary light-gas propulsion technology designed to reduce the cost and complexity associated with traditional rocket launches. The system uses hydrogen and oxygen gas propellant and is built around repeatable launch concepts, rapid operational potential, and efficient payload delivery. This approach helps research organizations access high-altitude testing environments with a more practical budget.

Yes. Green Launch specifically supports atmospheric sampling missions, including access to upper atmospheric regions such as the mesosphere and ionosphere. These missions can help climatologists, communications researchers, and surveillance technology developers gather data that is otherwise difficult to obtain. The company has designed and tested vehicles intended to carry instruments into these regions while protecting onboard systems during launch.

Green Launch uses proprietary light-gas propulsion technology based on hydrogen and oxygen gas propellant. This system is designed to accelerate payloads to very high velocities while producing water vapor as the primary byproduct. The company has demonstrated projectile launch velocities up to Mach 9 in testing and has used both horizontal and vertical launch campaigns to validate the technology for suborbital and future orbital applications.

Yes. Green Launch has completed multiple successful test campaigns, including 12 horizontal test firings at Yuma Proving Ground in early 2018, additional successful shots in April 2018, and further testing in July 2021. The company also completed a vertical launch attempt in December 2021 that sent a projectile into the stratosphere at speeds exceeding Mach 3, demonstrating meaningful progress toward practical suborbital access.

Typical users include aerospace and defense organizations, scientific research institutions, satellite manufacturers, and teams developing communications, navigation, surveillance, or atmospheric science technologies. These customers often need affordable access to high-altitude or reduced-gravity environments for testing and validation. Green Launch's service is especially relevant for organizations seeking a sustainable and cost-conscious alternative to conventional launch providers.

The planning process typically begins by defining the payload purpose, target altitude or flight profile, mass constraints, instrumentation needs, and data collection goals. From there, mission feasibility can be evaluated against Green Launch's suborbital capabilities and testing framework. Early coordination is important for technical integration, launch requirements, and scheduling, especially for research programs with specific experimental objectives or timelines.
