Third stage: capsule disengages with the LM; LM drops to a lower lunar orbit, and begins to descend to landing trajectory Schematic of the LM: - windows were relatively large for a spacecraft, even after being scaled down from initial designs - two dishes: rendezvous radar dishes - fuel tanks; engine - ascent stage (~10,000 lbs), descent stage (~25,000 lbs) - landing pads/feet (since rigidness of the moon’s surface was unknown) - 3 feet of shock absorbing capability in landing struts (took up hundreds of pounds of weight, but again, it was because they didn’t know how rigid the moon’s surface would be) Inside the LM’s cockpit: - circuit breakers; cycling different circuits by hitting the breaker actually played a...
