US launches satellite tracking climate change

The US Aeronautics Agency (NASA) will launch an artificial satellite to test the weather forecasting technology and monitor climate change on Earth.

Satellite - worth $ 1.5 billion - will be launched from Vandenberg, California state air base with a Delta 2. rocket. It will fly into orbit about 800km above the ground, the AP said.

After the orbit, the satellite will fly around the earth from north to south pole more than 10 times a day. Data will be transmitted to a ground station in Norway and then forwarded to the US via fiber optic cable. NASA will operate satellites in the first three months before transferring management to the US National Oceanic and Atmospheric Administration.

NASA has put a group of earth observation satellites on orbit. They measure indicators in the air, clouds and oceans. But many of these satellites have been used for too long and need to be replaced.

Satellite launchers - as big as a small bus - are more complex than previous satellites. It is equipped with 5 types of devices capable of collecting environmental data, of which four have never appeared in the universe.

One of the major tasks of satellites is to test new technologies. These technologies will be used by the next generation of satellites to more accurately predict storms, tornadoes and extreme weather events. In addition, they also help scientists monitor global warming.
