On Wednesday, ground crews rolled a fully assembled New Glenn rocket out of the hangar at LC-36 and up the ramp to the launch mount… The next step will involve "several demonstrations of cryogenic fluid loading, pressure control, and the vehicle's venting systems," Blue Origin said. According to a
report published by Aviation Week, Blue Origin will load this particular test vehicle with cryogenic liquid nitrogen as a stand-in for the super-cold methane and liquid oxygen propellants used by the first stage booster on an actual launch. The upper stage won't be loaded during this upcoming Integrated Tanking Test (ITT).
