NASA Radar Finds Ice Deposits at Moon's North Pole

Imagine looking up at the night sky and seeing a shiny ball. That ball is our Moon, and it’s full of surprises! Scientists have recently discovered a hidden treasure on the Moon – massive deposits of ice near its north pole. This discovery is a game-changer for our understanding of the Moon and its potential for future exploration and use.

Lunar Pioneer: 600 million metric tons of water ice at Moon's ...

The Moon, our closest celestial neighbor, is not the dry and barren place we once thought it was. It turns out that the Moon has water, and not just a little bit – we’re talking about trillions of pounds of water ice! This ice is hidden in craters near the Moon’s north pole, which are permanently shaded from the Sun. Because of this constant darkness and cold, the ice can survive indefinitely.

Discovering the Ice

Scientists used a special radar instrument called Mini-SAR, which flew aboard India’s Chandrayaan-1 spacecraft, to discover this hidden ice. Mini-SAR works by bouncing radio waves off the Moon’s surface and measuring how they bounce back. The scientists found that some craters had a different radar signature than others, indicating the presence of water ice.


Q: How much ice is on the Moon?

A: Scientists estimate that there could be at least 1.3 trillion pounds (600 million metric tons) of water ice near the Moon’s north pole.

Q: Why is this discovery important?

A: This discovery is important because it provides evidence that the Moon may have once been a much wetter place than we thought. It also shows that the Moon is a more promising destination for future human exploration and use, as water is essential for life and other activities.

Expert Advice

As an expert in space exploration, I’m excited about the implications of this discovery. The presence of water ice on the Moon opens up new possibilities for future missions, such as building a permanent Moon base or using the ice as a source of fuel for spacecraft.


The discovery of water ice on the Moon is a major breakthrough in our understanding of our celestial neighbor. It’s a reminder that there’s still so much we don’t know about our solar system and that the possibilities for future exploration are endless.
