Space Rocket History #218 – Apollo 11 – Lunar Orbit

As they passed behind the moon, they had just over 8 minutes to go before the burn. They were super-careful now, they checked and rechecked each step several times. It had to be perfect.

Space Rocket History #217 – Apollo 11 – Cislunar

What do we call this strange region between earth and moon? Cislunar space is the most common term, Is it day or night?  Humans generally define night as that time when our planet is between our eyes and the sun, so this must be considered constant daytime, But it looks like night out of Command Module’s windows.
