Griffin-1 passes environmental tests ahead of planned lunar delivery
Griffin-1 passed tests at NASA’s Jet Propulsion Laboratory that simulated launch vibration and noise, space vacuum, and extreme temperatures. The lander has returned to Voyager Lunar Systems for final assembly ahead of launch-readiness work and a planned launch later this year to deliver 10 science and technology demonstrations near the lunar South Pole.

Why it matters
The tests provide evidence that the spacecraft can withstand conditions on its journey, a necessary step before attempting lunar cargo delivery. Its planned payload includes Astrolab’s FLIP rover and demonstrations from six countries, making the remaining assembly and flight milestones relevant to multiple projects. [11]
Key insights
- Thermal-vacuum testing exposed Griffin-1 to temperatures ranging from minus 100 degrees Celsius to 75 degrees Celsius over about two weeks. [11]
- Separate tests checked mass properties and electromagnetic compatibility, addressing navigation behavior and whether onboard electronics interfere with one another. [11]
- Passing environmental tests is not the end of preparation: final assembly, launch-readiness operations, and shipment to Cape Canaveral remain. [11]
