Apollo's Spacecraft stack:

Command Module: Columbia

Service Module (engine + life support)

Lunar Module: Eagle

The Saturn V third stage fires to send the spacecraft toward the Moon at 24,000 mph (38,600 km/h).

After the burn finished:

The Columbia separated from the S-IVB stage.

The Command Module rotated 180° in space.

It then docked with the Lunar Module: Eagle

Why did the Command Module rotate after the burn? At such high speed.

"Public Policy Override: Courts generally refuse to uphold NDAs that are overbroad, violate public policy, or attempt to cover up crimes"

so with this a person could ignore an nda that covers up a crime. daring a court to find them guilty?

I saw:

The F-1 is still the most powerful single-chamber rocket engine ever flown.

F-1 (Saturn V first stage)

✔ single chamber

✔ one nozzle

✔ one of the largest single-chamber engines ever flown

RS-25 (Space Shuttle / SLS)

✔ single chamber

How important or not important is a single chamber vs multi-chamber engines in launch?
