The BE-3U engines, used in the second stage of New Glenn, produce 160,000 pounds of thrust and are designed for high efficiency with liquid hydrogen as the propellant.

The New Glenn rocket's booster is powered by seven BE-4 engines, each producing over 550,000 pounds of thrust, fueled by liquefied natural gas and liquid oxygen.

We're developing solar-powered cryo coolers to make hydrogen a storable propellant for deep space missions, which is a game changer for lunar and outer planet exploration.

The first stage of New Glenn is reusable, landing on a platform in the ocean for maintenance, while the second stage is expendable to maximize efficiency.

Astrome Mechanica plans to focus on launching payloads into orbit as a specific use case for their versatile engine, similar to Tesla's strategy.

Rockets tend to be more efficient when they are larger, as parasitic mass becomes less significant and engine efficiency improves with size.

New Glenn generates about 3.9 million pounds of thrust at liftoff, which is a little more than half the thrust of the Saturn V Rocket.

Starship is the most complex and advanced rocket ever made, and its fundamental optimization is to minimize the cost per ton to Mars.

The big innovation in space travel is making rockets reusable, which could lead to a 100-fold improvement in the cost of spaceflight.
