NASA Study Reveals Earth's Water Origins

NASA Study Reveals Earth's Water Origins

Scientists from NASA studied moon dust to learn where Earth's water came from.

They found that most of Earth's water likely came from the planet's original building blocks.

Meteorites that hit the Moon and Earth carried some water, but not much.

The Moon's dust keeps a record of these impacts, which helps scientists understand what happened billions of years ago.

This research is important for future missions to the Moon, especially to study icy areas near the poles.

The samples used in this study were collected by the Apollo missions over 50 years ago, and future missions will bring back more samples to learn even more.
