European Space Agency astronaut Alexander Gerst posted this view of the California wildfires, as seen from the International Space Station (ISS), on Twitter on Aug. 3, 2018.
"California burning. These fires are frightening to watch, even from space," European Space Agency (ESA) astronaut Alexander Gerst wrote via Twitter Friday (Aug. 3), where he posted images of several big fires and their even larger smoke plumes. "Here's a shout-out from space to all firefighters on this planet, my former colleagues. Stay safe, my friends!" [In Photos: The 2018 California Wildfires as Seen from Space]
A geophysicist and volcanologist, Gerst also worked as a volunteer firefighter while in school, according to his ESA biography.

NASA astronaut Ricky Arnold — a crewmember on the ISS' current Expedition 56 along with Gerst and four other spaceflyers — posted some fire photos of his own via Twitter today (Aug. 6).
"Plumes of billowing smoke from the #CaliforniaWildfires stretch eastwards [toward] the Rocky Mountains," Arnold tweeted.

The Mendocino Complex consists of two neighboring Northern California blazes, the Ranch and River fires. The Ranch Fire has scorched 225,001 acres (91,055 hectares) to date and is just 21 percent contained, according to the California Department of Forestry and Fire Protection (Cal Fire). The River Fire has burned 48,663 acres (19,693 hectares) and is 58 percent contained.
The Mendocino Complex fire has not killed anyone so far. The same cannot be said of the Carr Fire, which is raging farther north, in Shasta County; it has claimed seven lives to date. The Carr Fire has burned 163,207 acres (66,048 hectares) as of this morning and is 45 percent contained, according to Cal Fire.

ISS crewmembers aren't the only eyes tracking the fires from orbit. A variety of satellites are doing precision monitoring work, including NASA's Terra and Aqua craft.
