For decades, scientists have debated what’s beneath the Moon’s dusty surface. Now, new research has delivered some of the clearest evidence yet of what’s inside the Moon.

The Moon’s average distance from Earth is 238,000 miles (383,000 kilometers). It can be as far away as 252,724 miles (406,720 kilometers) or as near as 221,439 miles (356,372 kilometers).

The average age of the flight controllers on the Apollo 11 mission was 27. Without this group of youngsters in their twenties and thirties the first Moon landing wouldn’t have happened.
