# CLPS procurement mechanism solved VIPER's cost growth problem through delivery vehicle flexibility where traditional contracting failed

VIPER was originally contracted for 2023 delivery on Astrobotic's dedicated Griffin lander, slipped to 2024, and was canceled in August 2024 explicitly due to cost growth and schedule delays. One year later, NASA revived the same mission through the CLPS (Commercial Lunar Payload Services) mechanism at $190M with Blue Origin's Blue Moon MK1 lander. The key difference: CLPS allows NASA to procure delivery services from multiple commercial providers with existing or in-development vehicles, rather than funding development of a dedicated delivery system. Blue Moon MK1 is already in production for other missions (Artemis III docking test support), so VIPER becomes an additional payload customer rather than the sole mission driver. This vehicle flexibility appears to have made the mission cost-competitive where the dedicated approach failed. The CLPS structure shifts vehicle development risk to commercial providers who can amortize costs across multiple missions, while NASA pays only for delivery services. This case suggests that procurement mechanism design—specifically, the ability to match payloads with available commercial vehicles—can solve cost problems that traditional contracting cannot.

## Challenging Evidence

**Source:** Multiple outlets, April 19, 2026

NG-3 upper stage failure and subsequent FAA grounding creates timeline risk for VIPER late 2027 delivery. Blue Moon MK1 requires New Glenn reliability by mid-2027 to meet schedule, but no backup launch vehicle for VIPER appears documented in CLPS contract, revealing vehicle flexibility may not extend to launch vehicle substitution.
