Griffin Mission One (Griffin-1, NASA Moon Base II)
First flight of Astrobotic's Griffin lander (Astrobotic now operates as Voyager Lunar Systems), a NASA CLPS delivery to the lunar south pole with NASA's late-2026 target and Voyager's no-earlier-than-November-2026 bound (NASA names the Nobile Crater area; Voyager's 22 October 2026 article says near Mons Mouton). After NASA ended VIPER in 2024, its resource-relevant cargo is the NASA Ames/Interlune METAL investigation, which NASA says will study helium-3 abundance in the regolith.
Objective. Deliver NASA payloads including the METAL investigation (NASA Ames with Interlune), which NASA says will study helium-3 abundance in the lunar regolith to inform in-situ resource utilization.
What to watch for
From the records here, checked 2026-10-28. Planned dates often slip.
- Launch. Voyager gives no earlier than November 2026 and NASA gives late 2026. Neither is a launch day, and the two have not been reconciled.
- Landing. This is the Griffin lander's first flight, to the lunar south pole. NASA names the Nobile Crater area and Voyager says near Mons Mouton; whether those are the same area or a site change is not established.
- The helium-3 question. Since NASA ended VIPER in 2024, this flight's resource-related cargo is the METAL camera from NASA Ames and Interlune. It is intended to image lunar soil to map titanium content and soil maturity, which Interlune and NASA use as proxies to estimate helium-3. Any helium-3 estimate would be derived from those proxies.
- What would change here. Both records stand at Targeted for helium-3. A launch or a landing would not change that. Each stays at Targeted until reported evidence supports inferring or measuring helium-3 under the site's evidence steps. How the steps work
- Still open. Interlune says METAL flies on Astrolab's FLIP rover. NASA's Griffin-1 section lists METAL without naming FLIP, so the mounting is company-stated.

- Phase
- In developmentScoped schedule review on 2026-11-01: Voyager's 13 July 2026 release targets launch no earlier than November 2026. NASA's 13 October testing report still gives late 2026, while Voyager's October report describes final preparations before shipment. The date field records the published earliest-month bound, not a confirmed November launch. No actual launch or fixed launch day is established, so the phase remains in development. Older NASA schedule and landing-site discrepancies remain open.

Recorded change: the plan before → the plan after, oldest first.
- 2026-05-26: no earlier than fall 2025 → late 2026 (2026-H2 target)Schedule slip [3]

Only changes recorded here are listed. The oldest date shown may not be the first plan ever announced, and a date with no recorded change may still have moved. A plan is not a launch.

Open evidence gaps
- Interlune's 15 September 2026 blog says the company funded METAL's flight on Astrolab's FLIP rover; NASA's Moon Base Phases page lists METAL among Griffin-1 payloads and does not name FLIP in that section. The mounting on FLIP is therefore company-stated, not confirmed by the reviewed NASA section.
- Voyager's no-earlier-than-November-2026 statement is an earliest-month bound, not confirmation of a November launch or an exact day. NASA's October report says late 2026; older NASA pages retain earlier schedules. Their reconciliation and the actual launch day remain unresolved.
- Landing-site naming differs: NASA's Griffin-1 pages (October 2026) say Nobile Crater, while Voyager's 2026-10-22 article says near Mons Mouton. Whether these describe the same area or a site change is not established.
