The Northrop Grumman Pegasus XL rocket containing NASA's Ionospheric Connection Explorer (ICON) is seen outside the cleanroom after assembly at Vandenberg Air Force Base in California on Sept 19, 2019. ICON launched on the Pegasus XL rocket, attached beneath the company's L-1011 Stargazer aircraft, on Oct. 10, 2019, after takeoff from the Skid Strip at Cape Canaveral Air Force Station in Florida. ICON will study the frontier of space - the dynamic zone high in Earth's atmosphere where terrestrial weather from below meets space weather above. The explorer will help determine the physics of Earth's space environment and pave the way for mitigating its effects on our technology, communications systems and society.

In early August 2017, the Cinder Butte fire burned 9 miles (15 kilometers) outside of the town of Riley, Oregon, and consumed more than 82 square miles (53,000 acres) of forest and brushland. The fire threatened tribal archaeological sites with strong significance to the Burns Paiute and Klamath tribes. Firefighters were able to contain the fire before it could damage the historic sites. On the image, the burned area is gray-brown, and cloud shadows are dark gray-to-black. The image was acquired Aug. 23, 2017, covers an area of 20 by 25 miles (31.5 by 39.9 kilometers), and is located at 43.5 degrees north, 119.9 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA21879

Although large gullies (ravines) are concentrated at higher latitudes, there are gullies on steep slopes in equatorial regions, as seen in this image captured by NASA's Mars Reconnaissance Orbiter (MRO).
