Promethei Planum

Promethei Planum, an area seasonally covered with a more than 3500 m thick layer of ice in the martian south polar region, was the subject of the High Resolution Stereo Cameras focus on 22 September 2005 as Mars Express was in orbit above the Red Planet.
Promethei Planum lies at approximately 76° south and 105° east on the Red Planet. The image data acquired in the region has a ground resolution of approximately 40 m/pixel.
An impact crater that is approximately 100 km wide and 800 m deep is visible in the northern part of the image. The craters interior is partly covered in ice.

Mars Express took snapshots of Candor Chasma, a valley in the northern part of Valles Marineris, as it was in orbit above the region on 6 July 2006.
 The High Resolution Stereo Camera on the orbiter obtained the data in orbit number 3195, with a ground resolution of approximately 20 m/pixel. Candor Chasma lies at approximately 6° south and 290° east

Mars is about to come into 3D focus as never before, thanks to the data from the Mars Express High Resolution Stereo Camera (HRSC). A new high-resolution Digital Terrain Model data set that is about to be released onto the Internet, will allow researchers to obtain new information about the Red Planet in 3D.

 Digital Terrain Models (DTMs) allow scientists to stand on planetary surfaces. Although ordinary images can give spectacular birds-eye views, they can only convey part of the picture. They miss out on the topography, or the vertical elevation of the surroundings. Thats where Mars Express comes in.

Terby crater

The High Resolution Stereo Camera (HRSC) on board ESAs Mars Express has returned striking scenes of the Terby crater on Mars. The region is of great scientific interest as it holds information on the role of water in the history of the planet.
 The image data was obtained on 13 April 2007 during orbit 4199, with a ground resolution of approximately 13 m/pixel. The Sun illuminates the scene from the west (from above in the image). 
Terby crater lies at approximately 27° south and 74° east, at the northern edge of the Hellas Planitia impact basin in the southern hemisphere of Mars.

This small impact crater in Hellas Planitia (Hellas Impact Crater) has the lowest elevation on Mars.
The Hellas Planitia region is about 2,300 kilometres in diameter and about 9 kilometres deep.

Sulphur dioxide may have helped maintain a warm early Mars
Sulphur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists at Harvard University and the Massachusetts Institute of Technology (MIT) suggest in the Dec. 21 issue of the journal Science. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today.
The Science paper's authors are Itay Halevy, a Ph.D. candidate in Harvard's Department of Earth and Planetary Sciences; Daniel Schrag, professor of earth and planetary sciences and environmental science and engineering at Harvard; and Maria Zuber, professor of earth, atmospheric, and planetary sciences at MIT. A significant portion of the collaboration occurred during Zuber's 2002-03 year as a Radcliffe Institute fellow.

Mars: Closest Approach 2007
Credit: NASA, ESA, and G. Bacon (STScI)

NASA's Hubble Space Telescope took this close-up of the red planet Mars when it was just 88 million kilometres away. This colour image was assembled from a series of exposures taken within 36 hours of the Mars closest approach with Hubble's Wide Field and Planetary Camera 2. Mars will be closest to Earth on December 18, at 11:45 p.m. Universal Time.
