A Swarm of Satellites Will Soon Keep Us Safe From Fires

The GIF above, created by NASA, may leave you wondering why our government is building a planetary shield. Something you’re not telling us, NASA? According to the space agency, NASA’s shield plan has nothing to do with intergalactic threats—it’s protection against a danger on the ground. The space agency wants to build a global network of fire-monitoring satellites.

In light of recent events, namely, the Summer of Fire and Drought and Heat and More Fire, it’s not a bad idea. One of the main challenges facing fire-prone countries—look at Indonesia right now—is that blazes start in remote areas, often going undetected for hours or days, by which time, they’ve gotten really big and difficult to contain. FireSat could help.


Developed by the Jet Propulsion laboratory, the proposed fire-monitoring network would consist of over 200 space-based thermal imaging sensors with the sole purpose of rapidly locating fires around the globe and alerting the appropriate authorities.

According to NASA, FireSat would be able to sniff out fires—as well as other heat sources, like explosions—that are at least 35 to 50 feet wide, within 15 minutes from the time they begin. Once it spots a fire, the satellite swarm would keep some of its eyes trained on the blaze, capturing a low-res image approximately every minute, along with the fires’ latitude and longitude coordinates. Within three minutes of detection, FireSat would be able to notify emergency responders in the area. This sounds like an awesome idea.


FireSat has been in the works since 2011, but actualizing the concept at a reasonable cost has only become possible in the past few years, thanks to advances in commercial microelectronics like CubeSats. The plan is to have a fully operational deflector shield—sorry, fire monitoring system—by June of 2018.
