Mesosphere Payload Launch Service for Atmospheric Research

Green Launch utilizes a proprietary light-gas propulsion system powered by hydrogen and oxygen gas propellant. This unique chemical combustion scheme delivers extreme acceleration through a precision-engineered launch tube without generating harmful combustion byproducts. The only byproduct produced during ignition is water vapor, offering an eco-friendly and sustainable alternative to traditional solid and liquid rocket propellants for upper atmospheric missions.

The launch vehicles are constructed using specialized wound fiberglass designed specifically for high compression strength during rapid light-gas acceleration. In addition to high mechanical durability and low weight, this wound fiberglass material is naturally transparent to radio frequency signals. This allows research antennas to remain safely housed inside the vehicle body while maintaining clear communication, navigation, and surveillance capabilities during flight.

During extensive testing campaigns at Yuma Proving Ground, the system has achieved projectile launch velocities of 2.97 kilometers per second, which corresponds to Mach 9 using a one-stage light-gas combustion system. Vertical testing with our launch tube has accelerated projectiles into the stratosphere at speeds exceeding Mach 3, validating the platform's aerodynamic performance and ability to reach target sub-orbital altitudes.

Mesospheric access is vital for climatologists and atmospheric scientists who require direct atmospheric sampling of upper air layers. Scientists also depend on access to this region and the ionosphere to conduct essential research and development for navigation, communication, and surveillance technologies. Traditional vehicles struggle to sample this altitude consistently, making our rapid launcher ideal for entities like the National Science Foundation.

Green Launch conducts its testing firings and launch operations at the Yuma Proving Ground in Arizona. This military testing installation provides the necessary range safety, tracking infrastructure, and operational support for high-velocity horizontal test firings and vertical sub-orbital projectile flights. Multiple testing campaigns have validated gas manifold controls, pressure parameters, and projectile performance at this facility.

Unlike conventional rocket boosters that burn toxic solid propellants or ozone-depleting chemicals, our light-gas launch system uses clean hydrogen and oxygen propellant. Because the only exhaust emission produced is clean water vapor, launches create zero carbon footprint. Furthermore, our demonstrated propellant capture technology captures over 91 percent of the propellant, significantly reducing acoustic signatures and muzzle flash during release.

Launch campaigns begin with mission parameter analysis, gas charge pressure calibration, and payload integration inside the compression-tested vehicle body. The vehicle is loaded into the launch tube at the test facility. A precision gas injection scheme prevents errant detonation inside the combustion chamber, safely releasing pressurized light gas to propel the aerodynamic projectile vertically into the stratosphere and mesosphere within minutes.

Yes, our light-gas launcher is specifically designed and tailored to support hypersonic vehicle testing. Green Launch has launched scramjet test vehicles at velocities reaching up to Mach 9, obtaining high Mach number engine operation records in free-flying scramjets at Mach 8. Aerospace and defense entities can utilize our platform to test aerodynamic materials, sensors, and experimental hypersonic propulsion components.
