Mesosphere Launch Service Overview

A mesosphere launch delivers payloads into the atmospheric layer between approximately 50 and 85 kilometers altitude. Traditional weather balloons cannot float this high, and orbital satellites cannot operate this low due to atmospheric drag. Green Launch utilizes high-velocity light-gas launch tubes to propel specialized scientific projectiles directly through this boundary for atmospheric sampling and research.

The launch mechanism operates on a light-gas propulsion platform fueled by hydrogen and oxygen gas combustion. Because hydrogen and oxygen combustion produces only water vapor, our launches achieve zero carbon emissions. Additionally, our testing demonstrates propellant capture exceeding 91 percent, which reduces acoustic signatures and muzzle blast during operations.

Payload vehicles are engineered using specialized wound fiberglass composite bodies capable of withstanding intense compressive forces during acceleration. Because this wound fiberglass material is transparent to radio frequencies, sensitive antennas and telemetry sensors remain fully encased and protected inside the vehicle body while maintaining clear communication transmission during flight.

Flight trials, horizontal firings, and vertical launch campaigns are conducted at Yuma Proving Ground in Arizona. Our team has completed multiple series of successful test shots at this facility, evaluating gas charge pressures, release peak pressures, vehicle weights, and muzzle velocities across horizontal and vertical launch configurations.

The launch system is designed for scientific instruments, atmospheric sampling devices, RF communications experiments, and navigation and surveillance sensors. Scientific research organizations, including climatology researchers and entities like the National Science Foundation, utilize these payloads to collect vital empirical data in the ionosphere and mesosphere.

Green Launch systems have achieved projectile velocities of 2.97 km/s, equivalent to approximately Mach 9, in light-gas combustion setups. In vertical test configurations utilizing a 54-foot launch tube, the system has demonstrated payload velocities exceeding Mach 3 into the stratosphere and upper atmospheric layers.

Traditional sounding rockets rely on expendable solid or liquid rocket motors that are expensive to manufacture and discard after each flight. In contrast, Green Launch relies on reusable ground-based launcher tubes with clean gas propellants, drastically reducing per-launch mission costs while enabling rapid turnaround times between successive shots.

Interested research institutions, defense partners, and commercial customers can coordinate directly with our engineering team. We evaluate payload mass, sensor specifications, and flight trajectory requirements to configure custom vehicle bodies and schedule integration windows for our upcoming test campaigns.
