Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] Joan Cartan-Hansen, Host: Mars wasn't always the dry and dusty place we see today.
Scientists think that billions of years ago Mars was a warm, wet world.
So, what happened?
Mars is smaller than the Earth, so it has less gravity and a thinner atmosphere.
Over time, the surface water evaporated and escaped into space instead of falling back to the ground.
So eventually, the red planet's surface dried out.
Scientists have described the red planet as a kind of frozen desert.
But that doesn't mean there's no water on Mars.
There's evidence to suggest that there's water trapped within the ice caps of the north and south poles of the planet.
And scientists think there may be frozen slabs of water the size of California and Texas trapped beneath the planet's surface.
So, NASA has a theme for exploring Mars.follow the water.
