NASA astronaut Karen Nyberg transmitted this image of smoke wafting from California's Rim Fire, as seen from the International Space Station, via Twitter on Monday. North is to the left in this image.
The 150,000-acre fire blazing in and around Yosemite National Park made a big impression on NASA astronaut Karen Nyberg, who was watching the smoke from the International Space Station on Monday.
"Our orbit took us directly over California's Rim Fire about an hour ago. Devastating," Nyberg wrote in a Twitter update.
Nyberg isn't the only one keeping track of the blaze from outer space: The MODIS imaging spectrometers that NASA has aboard its Aqua and Terra satellites are keeping watch on the Rim Fire as well as other wildfires across the West.
A map from the National Interagency Fire Center helps you get a fix on the extent of the Rim Fire, in relation to California's Mono Lake as well as Yosemite National Park's famous Half Dome.
The spectrometers are sensitive enough to detect the warm surface temperatures associated with active fires. Those are indicated on the MODIS imagery by red outlines.
What you see here is a view of the Rim Fire captured by Terra's MODIS instrument on Sunday. An earlier satellite image from Terra shows fires burning in California and Idaho. Meanwhile, Aqua's MODIS imager took in a view of at least 20 fires burning in Idaho, Montana and Wyoming, as seen from space on Aug. 20.
NASA's "Fire and Smoke" Web page features still more wildfire pictures from around the world.
An image from the MODIS instrument on NASA's Terra Satellite, acquired on Aug. 25, shows the active burning areas of the Yosemite Rim Fire in red outlines.
