The surface of Venus is dominated by geologic features that include volcanoes, large impact craters, and aeolian erosion and sedimentation landforms. Venus...

The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily...

The two moons of Mars are Phobos and Deimos. They are irregular in shape. Both were discovered by American astronomer Asaph Hall in August 1877 and are...

The terraforming of Mars or the terraformation of Mars is a hypothetical procedure that would consist of a planetary engineering project or concurrent...

of Mars. Scientists have known since the Mariner 9 mission in 1972 that volcanic features cover large portions of the Martian surface. These features...

albedo features of Mars are the light and dark features that can be seen on the planet Mars through an Earth-based telescope. Before the age of space probes...

Mars may contain ores that would be very useful to potential colonists. The abundance of volcanic features together with widespread cratering are strong...

Triton Common rigid surface features include: Impact craters (though rarer on bodies with thick atmospheres, the largest being Hellas Planitia on Mars) Dunes...

The Mars ocean theory states that nearly a third of the surface of Mars was covered by an ocean of liquid water early in the planet's geologic history...

that most of the channels were cut since the early Hesperian, though the age of the features is variable between different regions of Mars. Some outflow...

The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late 1940s as part of the broader exploration...

Mars Exploration Program (MEP) is a long-term effort to explore the planet Mars, funded and led by NASA. Formed in 1993, MEP has made use of orbital spacecraft...

The study of surface characteristics (or surface properties and processes) is a broad category of Mars science that examines the nature of the materials...
