Green Launch has just successfully completed development of extended capabilities for our light-gas kinetic launch system. As proposed by Jules Verne we have found the fastest way to space is a hypersonic space launch tube. In our case we have substituted 3x faster hydrogen for gunpowder. We have launched projectiles horizontally to hypersonic velocities, Mach 6, and vertically to 33 km.

We do not have significant physical limitations in reaching our velocity requirements. The record for a projectile launched with hydrogen propellant is 11.2km/sec. We plan to limit our launch velocity to 6 km/sec to extend reusability and prevent wear on the barrel. At altitude an onboard rocket would need to produce an additional, and achievable, 3 km/sec to circularize and achieve orbit. 

1) Propellant capture - Compared to rocket which produce 19 tons of CO2 for each ton put into orbit. This hydrogen light-gas launcher features a fast valve that closes after the vehicle leaves the launch tube catching up to 99% of the propellant for reuse. This is an extremely environmentally friendly launch method. 

This capture reduces muzzle flash and allows for low acoustic & heat signature reducing impact on the environment. For defense applications, our fast acceleration, hypersonic launch capability give countermeasures the advantage of intercepting ordnance earlier and at greater range, 500 km, than traditional rocket powered countermeasures.

2) MOXI - We have eliminated the detonation risk that has plagued legacy Light-Gas (hydrogen) launchers. This increases the safety, reliability and ultimate velocity of our launch system between 1 and 4 km/s.

3) Baffled chamber on the muzzle - this muffler significantly reduces the dB level, resulting in quieter operation during hypersonic launch. Increased ease of operation and impact on personnel nearby.

4) G-hardening electronic payloads to operate in this impulse launch environment.

We are interested in explaining how our system has predominant advantages in

1. The hypersonic delivery of kinetic disabling materials, tungsten fragments, to intercept incoming ordnance.
2. Affordable hypersonic targets to repeatedly exercise any other countermeasures for effectiveness.
3. Hypersonic materials testing,

The technology is straight-forward and our company's strength is launching objects between 2 km/s and 6 km/s (Mach 6 and Mach 17). For orbital applications one has:

1. The ruggedized vehicle is launched ballistically at high speed and it penetrates the atmosphere within a minute and sheds the aeroshell
2. A rocket engine fires which provides the added velocity to attain the desired apogee which can be 300 km to 1,000 km altitude and to circularize the orbit.
3. The satellite or emergency supplies is maneuvered to the desired orbital location within 2 hours

Due to air friction and subtleties of The Rocket Equation, launching small payloads with rockets is difficult to do economically. Fortunately, this niche is accessible with light-gas kinetic launcher. Our future markets range from just in time supplies like medicine, tools and small satellites, to delivering large amounts of propellant and consumable to depots in support of space missions. Our customers are Commercial, Defense and Academic/Environmental.
