NASA to study carbon dioxide in space

NASA is going to launch a satellite next month to study what happens to carbon dioxide, the main cause of global warming, after it leaves the earth's atmosphere.

After vehicles and factories release carbon dioxide into the air, the world's oceans and land absorb about half of it.

But scientists haven't been able to figure out yet, what happens to the rest of the carbon dioxide.

For two years, the satellite will cover all of the earth every 16 days.
