## FAQs
### Q: What was Intrepid?
A: Intrepid was the Lunar Module (LM-6) used on NASA's Apollo 12 mission. It was the spacecraft that descended from lunar orbit and landed astronauts on the Moon at Oceanus Procellarum.

### Q: When and where did Intrepid land on the Moon?
A: Intrepid landed on the Moon on 1969-11-19 at 06:54:35 local mission time at Oceanus Procellarum. The landing site coordinates are latitude −3.0128 and longitude −23.4219.

### Q: Who built and launched Intrepid?
A: Intrepid was manufactured by Grumman and was launched by a Saturn V rocket (SA-507) from Kennedy Space Center Launch Complex 39A on 1969-11-14 at 16:22:00.

## Why It Matters
Intrepid served the critical role of delivering Apollo 12 astronauts from lunar orbit to the lunar surface and back to orbit. As an Apollo Lunar Module, it embodied the lander design that enabled crewed lunar surface operations during the Apollo program. Its successful launch, descent, surface operations at Oceanus Procellarum, and ascent back to lunar orbit illustrate the core capability required for human lunar exploration: a purpose-built vehicle capable of powered descent, surface support, and ascent for rendezvous. The module’s documented mass, dimensions, serial identification (LM-6), and mission timeline provide concrete technical and historical data for understanding lunar mission architecture and performance. Intrepid’s mission events, including precise launch and landing timestamps and subsequent jettison in lunar orbit, form part of the operational record of Apollo hardware and contribute to the documented lineage of crewed lunar exploration systems.
