 NG-3 grounding creates binary fork in VIPER timeline: systematic BE-3U flaw requires months of rework and would push VIPER beyond 2027; random hardware failure allows 6-8 week return to flight. The systematic-vs-random determination is the critical near-term indicator for whether VIPER's 2027 delivery survives, which directly affects the post-2029 ISRU constraint.

+New Glenn grounding creates direct timeline risk for VIPER's late 2027 launch window. Blue Origin is contracted to deliver VIPER to the lunar south pole using Blue Moon MK1 lander carried by New Glenn. If the BE-3U thrust deficiency root cause is systematic (design flaw rather than hardware anomaly), return to flight could take 3-6 months, pushing VIPER close to or past its 2027 launch window. This is the third consecutive failure/delay signal in the ISRU prerequisite chain: PRIME-1 failed, PROSPECT delayed, and now VIPER launch vehicle grounded.
