Perspective view in Noctis Labyrinthus

In this image taken on 15 July 2015 by the High-Resolution Stereo Camera (HRSC) aboard ESA’s Mars Express you can see a perspective view in Noctis Labyrinthus on Mars. Visible are details of landslides in the steep-sided walls of the flat-topped graben (https://goo.gl/Rma96b) in the foreground, and in the valley walls in the background. Image resolution is about 16 meters per pixel.

Active Fires on Earth in September 2015

In this image you can see active fires on Earth in September 2015 imaged by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite. The image is color-coded,  white pixels show the high end of the count — as many as 100 fires in a 1,000-square-kilometer area per day. Yellow pixels show as many as 10 fires, orange shows as many as 5 fires, and red areas as few as 1 fire in a 1,000-square-kilometer area per day.

More active fire maps and other datasets can be found here at NASA’s Earth Observation (NEO) website:

Terra (EOS AM-1) satellite

The Terra satellite is part of the Earth Observing System (EOS, https://goo.gl/XYed36), its Moderate Resolution Imaging Spectroradiometer (MODIS) can take measurements in 36 spectral bands ranging in wavelength from 0.4 µm to 14.4 µm, another MODIS instrument is orbiting Earth aboard the Aqua satellite.
