What You'll Learn
Fuel type used by Blue Origin
Blue Origin's New Shepard rocket, designed for suborbital flights, primarily uses a combination of liquid oxygen (LOX) and highly refined kerosene, known as RP-1. This fuel type is a staple in the aerospace industry due to its high energy density and reliability. RP-1, a rocket-grade kerosene, is similar to jet fuel but undergoes additional purification to remove impurities that could hinder engine performance. The choice of RP-1 and LOX is strategic, as it balances cost-effectiveness with the necessary thrust for short-duration missions, such as those carrying passengers to the edge of space and back.
The fuel system in New Shepard is engineered for efficiency and safety. The LOX and RP-1 are stored in separate tanks and pumped into the BE-3 engine, where they are combusted to produce thrust. This engine is a single, powerful unit that provides both propulsion and control during ascent and descent. Notably, the BE-3 is a reusable engine, aligning with Blue Origin’s goal of reducing space access costs through reusability. The fuel mixture is optimized for rapid ignition and stable combustion, ensuring reliable performance even in the vacuum of space.
Comparatively, Blue Origin’s fuel choice contrasts with other space companies like SpaceX, which uses a combination of liquid oxygen and rocket propellant (RP-1) but also employs methane for its Raptor engines in the Starship program.

Environmental impact of Blue Origin's fuel
Blue Origin's New Shepard rocket, designed for suborbital flights, primarily uses a combination of liquid oxygen (LOx) and highly refined kerosene (RP-1) as its fuel. While these propellants are relatively clean-burning compared to solid rocket fuels, their environmental impact is not negligible. Each launch consumes approximately 100,000 pounds of LOx and 30,000 pounds of RP-1, releasing carbon dioxide (CO₂) and water vapor into the atmosphere. This raises questions about the sustainability of frequent launches, especially as Blue Origin aims to scale up its operations.
Analyzing the emissions, RP-1 combustion produces roughly 3.2 kilograms of CO₂ per kilogram burned. For a single New Shepard launch, this equates to approximately 96,000 kilograms of CO₂, roughly equivalent to the annual emissions of 20 passenger vehicles. While this may seem modest compared to aviation or ground transportation, the cumulative effect of multiple launches could become significant. Additionally, the production and transportation of LOx and RP-1 involve energy-intensive processes, further contributing to the rocket's overall carbon footprint.
