Wildfires often get 'wild' when they begin in a rural area where fewer people are around to notice the growing flames. Now, NASA plans to detect fires from space, no people needed. FireSat will be a network of 200 satellites equipped with temperatures sensors encircling the entire globe. The sensors would be able to detect fires when they are 35-50 feet wide (so don't worry, no one will be taking pictures of your backyard barbecue) within 15 minutes of their start. NASA hopes to have the network, which can also be used to monitor explosions and oil spills, operational by June 2018.
