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: Could humans live on Mars?
Let's compare the two planets.
The Earth is about 93 million miles away from the Sun.
Mars is about 142 million miles away.
So that means Mars isn't as warm.
The average temperature on Earth is a comfortable 57 degrees Fahrenheit.
But the average temperature on Mars is a bone-chilling negative 81 degrees Fahrenheit.
The Earth's atmosphere is more than 100 times denser and is mostly nitrogen and oxygen.
Mars' atmosphere is pretty thin, so it doesn't give us much protection from the Sun's radiation.
And it's almost entirely carbon dioxide.
That's poisonous to humans.
And if we were going to live on Mars, we'd need water.
But so far, scientists think the only water on Mars is frozen in the poles or trapped beneath the surface.
So, Mars is an interesting place to explore, but so far the Earth is the place to live.
