What engines and propellants define the first stage (GS1) of the $7\times 2$ New Glenn?
Answer
Seven BE-4 engines using liquid oxygen ($\text{LOX}$) and liquid methane ($\text{CH}_4$)
The propulsion architecture for the standard $7\times 2$ version's first stage, designated GS1, utilizes seven engines built by Blue Origin called BE-4. These powerful engines operate using a combination of liquid oxygen ($ ext{LOX}$) as the oxidizer and liquid methane ($ ext{CH}_4$) as the fuel. This choice of propellants for the booster stage differentiates it from the upper stage engines, which employ different propellants.
