Europe launches Sentinel-1A satellite to monitor climate change

The video discusses the launch of a satellite to 700 kilometers above Earth, where it orbits via the poles. The satellite's radar can penetrate clouds to observe floods and fires in any weather. It also monitors Earth's movements to locate earthquake centers. Additionally, the Sentinel 1A satellite transfers data to Earth's Rapid Data Relay System stations as it passes over Europe.
