Part 3/8:
The decision to abort the launch was due to ice forming in a purge line of an auxiliary power unit — an issue critical to the rocket’s hydraulic systems. This situation underlines the struggles of operating a rocket with complex systems, especially given New Glenn’s reliance on extreme temperature-sensitive liquid oxygen and methane. Such setbacks raise broader concerns about New Glenn’s reliability and its operational readiness, particularly as Blue Origin previously recorded successes in wet dress rehearsals and static fire tests. Compounded by issues from previous hardware challenges, these inconsistencies might prompt closer scrutiny from the FAA regarding Blue Origin’s operational procedures.
