Episode 355 - Satellites keeping us safe on the ground

December 2, 2019

Satellites can help save lives down on earth, by helping us better respond in disasters. When a flood, tsunami or other disaster strikes, satellites can help emergency responders get where they need to be as fast as possible. Satellites can track floods in near real time and help shave minutes of disaster response times. Finding your way in a flood or fire can be tricky, but satellites can help direct emergency responders. Satellites can help track critical infrastructure like bridges or roads as they age. When a bridge fails it can be a tragedy, but satellites can help give an early warning. When we dig big tunnels we can disturb structures and buildings, so how can we use satellites to avoid a disaster.
