Today, Mars is believed to be largely tectonically inactive. However, observational evidence and its interpretation suggests that this was not the case further back in Mars's geological history. At the scale of the whole planet, two large scale physiographic features are apparent on the surface. The first is that the northern hemisphere of the ...
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
Mars-1 was the first spacecraft launched to Mars in 1962, [266] but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of ...
A potent quake recently shook the Martian desert.NASA's InSight lander — sent to probe Mars' inner workings — observed the largest temblor ever detected on another planet on May 4. The ...
In 2006, researchers using data from the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer on board the Mars Express orbiter proposed an alternative Martian timescale based on the predominant type of mineral alteration that occurred on Mars due to different styles of chemical weathering in the planet's past. They proposed dividing ...
The InSight Mars lander has turned out to be a gift that keeps on giving. Even though its mission ended late last year, the data sent back to Earth by the lander has continued to provide new and ...
NASA announced on Thursday that a "mole" on Mars has ended its mission after landing on the Red Planet nearly two years ago. The mole — also called a digger, drill, and probe — was built by ...
In 2022, several elements of space debris were found on Mars: Perseverance's backshell was found on the surface of Jezero Crater, [253] and a piece of a thermal blanket which may have come from the descent stage of the rover. [254] [255] As of February 2024, Mars is littered with about seven tons of human-made debris. Most of it consists of ...
