They can last for months and cover the entire planet. The seasons are extreme because its elliptical (oval-shaped) orbital path around the Sun is more elongated than most other planets in thesolar system. On Mars the Sun appears about half the size as it does on Earth. ...
A size comparison of the Earth and Mars. Image credit: NASA. Over the course of the Earth's history, about a billion tons of rocks have been exchanged between the Earth and Mars. Scientists think it's possible that one or more of those rocks might have contained tiny microbes that succes...
In terms of their size and mass, Earth and Mars are quite different. With a mean radius of 6371 km and a mass of5.97×1024kg, Earth is the fifth largest and fifth most-massive planet in the Solar System, and the largest of the terrestrial planets. Mars, meanwhile, has a radius of a...
Mars is also roughly intermediate in size, mass, and surface gravity between Earth and Earth's Moon (the Moon is about half the diameter of Mars, whereas Earth is twice; the Earth is about nine times more massive than Mars, and the Moon one-ninth as massive). The red-orange appearance...

such as size and temperature. Although the same materials make up Earth and Mars, they are present in different amounts. The two planets are also thought to have formed at about the same time, although they evolved to become very different. While Earth is home to many forms of life, whet...

Although returned flight data have proven invaluable for reconstructing parachute system performance, the lack of video has left open the possibility of off-nominal or asymmetric inflations that could have led to excessive localized stresses and canopy damage. The Advanced Supersonic Parachute Inflation ...
but we cannot clearly differentiate between landslides down Shackleton crater's inner wall and underlying topography as contributing factors to its hummocky floor. While central peaks for lunar craters of Shackleton's size are uncommon, they do exist and would be expected to be on the order of ~...
The Earth's core is inferred to be iron-rich from (1) the core's density as deduced from the core's size and the planet'smoment of inertia, (2) computer models of the bulk composition of the Earth and compared with the composition of the chondritic meteorites from which the Earth for...
