Blue Origin has confirmed that at 9 p.m. ET, the rocket was being loaded with propellant for its upcoming mission. The fueling process, as per a mission timeline shared by Blue Origin, typically takes about three and a half hours to complete.
The process begins with the loading of liquid hydrogen onto the upper stage of New Glenn, which is the top part of the rocket attached to the cargo bay and houses two engines designed for operation in the vacuum of space. Approximately 30 minutes later, the company starts loading liquid oxygen into both the top and bottom sections of the rocket. Liquid oxygen, also known as LOX, serves as an oxidizer that enables the fuel to combust, resulting in the fiery blaze emitted by rocket engines.
