major features—Acidalia Planitia,Syrtis Major, and a dark collar around the pole—which were once considered to be shallow seas or vegetated regions. It is now known that many of Mars’s dark areas form and change as winds move dark sand around the surface or sweep areas free of bright ...
A fifth major striking features if the behavior of liquid water is unstable because of Mars’s present pressure and temperature conditions. Despite the abundance of water, however, Mars if arid. It has the mineralogy of a nearly waterless surface. On earth, the action of water liquid water ...
[03:48.20]the helicopter was traveling in an area [03:51.88]with very few surface features for the camera to capture. [03:57.00]This meant the aircraft's navigation system [04:01.80]could not find enough of these ...
According to NASA, some surface features suggest that Mars experienced huge floods about 3.5 billion years ago. Orbital pictures show vast river plains and possible ocean boundaries, while several Mars rovers have found evidence of water-soaked rocks on the surface (such as hematite or clay). ...
Selected major features of the planet and spacecraft landing sites are labeled. This perspective demonstrates the contrast in relief between the planet's northern and southern hemispheres and the dominance of Tharsis in the western hemisphere.(more) The character of the Martian terrain has been well...
The two most striking surface features on Mars are the Tharsis Rise and the crustal dichotomy1,2. The crustal dichotomy, an elevation difference of∼5 km between the southern highlands and the northern lowlands, is the oldest geological feature on Mars, and the Tharsis Rise is a vast volc...

While it would be a major leap to suggest that Mars might harbor(怀有,拥有)life -- even microbial life -- liquid water at least makes it possible that parts of the planet are habitable(可居住的). The study builds on research from April, when scientists using data from the Curiosity rove...
A group of more than 20 researchers at the Chinese Academy of Sciences has since used data obtained by cameras and detectors aboard the rover to study the different-scale surface features and material compositions of dunes in the landing area. ...
