Low-Cost Orbital Propellant Delivery Service

Low-cost orbital propellant delivery is the transport of fuel or related payload mass to Low Earth Orbit at a lower cost than conventional launch methods. Green Launch is developing this capability using proprietary light-gas propulsion technology, with a stated target of delivering payloads at $100 per pound. The goal is to support space depots, refueling missions, and broader orbital logistics.

Green Launch reduces costs by using a light-gas propulsion approach rather than relying solely on traditional rocket architectures. Its system is designed for efficient acceleration, rapid launch cadence, and simplified delivery economics. The company also emphasizes repeatable testing, high-velocity performance, and operational concepts such as launches every 60 to 90 minutes to improve throughput and lower mission costs.

Green Launch supports several payload categories, including orbital propellant, satellites, supplies, sub-orbital research payloads, and atmospheric sampling missions. Its platform is also relevant for hypersonic testing applications. This makes the service suitable for satellite manufacturers, scientific research organizations, and aerospace or defense customers seeking specialized high-altitude or orbital delivery capabilities.

Green Launch uses hydrogen and oxygen gas propellant, with water vapor identified as the primary byproduct. This gives the system a lower-emission profile than many conventional launch approaches. The company positions its technology as a sustainable alternative for space access, combining reduced launch costs with cleaner propulsion chemistry for customers prioritizing environmental considerations alongside mission performance.

Yes. Green Launch has completed multiple successful horizontal test firings at Yuma Proving Ground and achieved vertical launch testing as well. The company reports projectile velocities up to 2.97 km/sec, or Mach 9, in testing, along with a first vertical attempt that accelerated a payload beyond Mach 3. These milestones help validate the underlying propulsion concept.

This service is designed for organizations that need affordable, responsive access to high-altitude or orbital delivery. Likely customers include aerospace and defense firms, scientific research institutions, satellite manufacturers, and future in-space logistics operators. It is especially relevant for missions involving orbital resupply, propellant depot support, atmospheric research, and technology demonstration payloads.

Green Launch describes an operational vision that includes delivering payloads to orbit in about 10 minutes and supporting launches every 60 to 90 minutes. While actual mission timelines depend on payload readiness, testing status, and regulatory requirements, this concept highlights the company's focus on responsive launch operations and faster logistics compared with traditional scheduling models.

Green Launch combines proprietary light-gas propulsion, lower targeted delivery costs, and a cleaner propellant profile into a distinct alternative to conventional rocket launches. The company is also pursuing high launch cadence and orbital propellant logistics, not just satellite deployment. That combination of cost focus, sustainability, and logistics-oriented mission design sets it apart in the emerging space access market.
