+**Source:** Starship V3 cost projections and Suncatcher threshold analysis, April 2026
+
+Starship V3 with tripled payload capacity and Raptor 3 cost reduction makes the $200/kg threshold achievable within 2-3 years of routine operations according to analyst projections. V3 economics at projected high-cadence operations approach this threshold, validating that the Suncatcher threshold is not just theoretically sound but practically reachable within the current Starship development roadmap.

+## Challenging Evidence
+
+**Source:** New Glenn NG-3 failure impact analysis, April 19-24, 2026
+
+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.
