Mars Odyssey Captures New Thermal Images of Phobos

Jun 8, 2020 by News Staff

Astronomers using the Thermal Emission Imaging System (THEMIS) camera on NASA’s Mars Odyssey orbiter have captured new infrared images of Phobos, the...

These three views of the Martian moon Phobos were taken by NASA’s Mars Odyssey orbiter using its THEMIS camera. Each color represents a different temperature range. The upper image was taken in a full-moon phase, which is better for studying material composition. The two views below were taken while Phobos was in a half-moon phase, which is better for studying surface textures. Image credit: NASA / JPL-Caltech / ASU / SSI.

As strong impulses strike the Earth’s magnetopause, the abrupt boundary between the planet’s magnetosphere and the surrounding plasma, ripples travel...

This image combines two products from the first pointing at Phobos by Mars Odyssey’s THEMIS camera. Surface-temperature information from observation in thermal-infrared wavelengths is overlaid on a more detailed image from a visible-light observation. The left edge of the small moon was in darkness, and the right edge in morning sunlight. The distance to Phobos from Mars Odyssey during the observation was about 3,424 miles (5,511 km). Researchers will analyze the surface-temperature information from this observation and possible future THEMIS observations to learn how quickly the surface warms after sunup or cools after sundown. That could provide information about surface materials, because larger rocks heat or cool more slowly than smaller particles do. The thermal information in this image is from merging observations made in four thermal-infrared wavelength bands, centered from 11.04 microns to 14.88 microns.
