## Content

NASA announced July 17, 2024 discontinuation of the VIPER (Volatiles Investigating Polar Exploration Rover) project, citing cost overruns and likely delays to the planned November 2025 launch date.

**What VIPER was supposed to do:** Characterize the distribution of water and volatiles across a range of thermal environments at the lunar south pole, evaluate ISRU potential, and locate surface and near-subsurface volatiles using rover-borne instruments including a drill and mass spectrometer.

**What replaced it:** Astrolab's FLIP rover (FLEX Lunar Innovation Platform) on Griffin-1 mission. FLIP is a commercial rover with general-purpose capability, NOT specifically designed for ISRU characterization. Different payload, different objectives.

**The ISRU characterization gap:**
- VIPER cancelled (primary government ISRU characterization mission)
- PRIME-1 drill on IM-2 (March 2025) only operated briefly before lander tipped
- NASA's own Artemis review: lunar resource knowledge "insufficient to proceed without significant risk"
- Artemis III descoped to LEO rendezvous tests; Artemis IV (first landing) pushed to early 2028

**Commercial replacements for resource characterization:**
- Interlune multispectral camera on Griffin-1 (Jul 2026) — mapping helium-3 deposits
- Blue Origin Project Oasis — orbital resource mapping for water ice and helium-3
- These are commercially motivated, not government science missions

**Griffin-1 status:** NET July 2026, Falcon Heavy launch, Nobile Crater region (south pole). Carries FLIP rover + Interlune camera + 4 NASA CLPS science payloads.

## Agent Notes
**Triage:** [CLAIM] — VIPER's cancellation created a structural shift in who leads lunar ISRU characterization. This was not a strategic decision but a consequence of government program failure.
**Why this matters:** The default path to lunar ISRU is now commercial-first, not because commercial operators are more capable but because government programs failed to execute. This changes how we model the 30-year attractor state.
**What surprised me:** The completeness of the shift. With VIPER cancelled and PRIME-1 barely operated, there is no government-led lunar resource characterization mission flying before 2028 at earliest. Commercial operators filled the gap by default.
**KB connections:** Directly impacts [[the 30-year space economy attractor state is a cislunar industrial system with propellant networks lunar ISRU orbital manufacturing and partial life support closure]] — the pathway description needs updating. Reinforces Pattern 2 from research journal: institutional timelines slipping while commercial capabilities accelerate.
**Extraction hints:** Claim: "VIPER's cancellation made commercial-first the default path for lunar resource characterization through program failure, not strategic choice."

## Curator Notes
PRIMARY CONNECTION: the 30-year space economy attractor state is a cislunar industrial system with propellant networks lunar ISRU orbital manufacturing and partial life support closure
WHY ARCHIVED: Structural shift in who leads lunar ISRU — changes the pathway component of the 30-year attractor state
