Methods dating back to 17th-century techniques developed by Nicholas Steno, including the so-called law of superposition and stratigraphy, used to estimate the geological histories of Earth and the Moon, are being actively applied to the data available from several Martian observational and measurement resources.
[31] [32] Mars has twice as much iron oxide in its outer layer as Earth does, despite their supposed similar origin. It is thought that Earth, being hotter, transported much of the iron downwards in the 1,800 kilometres (1,118 mi) deep, 3,200 °C (5,792 °F ), lava seas of the early planet, while Mars, with a lower lava temperature of 2,200 °C ...
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.
The Curiosity rover has been poking around the Gale crater on Mars for a few years now, and it turns out the place may be more similar to Earth than we originally thought. Using rock data gathered ...
NASA's Curiosity rover has been exploring the Gale Crater on Mars since 2012, and in that time has come up with some astounding discoveries that suggest the Red Planet was somewhat Earth-like in ...
The geology of Mars is the scientific study of the surface, ... No topography is visible on Mars from Earth. ... (USGS, 2014) (original / crop / full / video (00:56 ...
Originally formulated by two independent research groups in 1976, the giant impact model supposed that a massive planetary object the size of Mars had collided with Earth early in its history. The impact would have melted Earth's crust, and the other planet's heavy core would have sunk inward and merged with Earth's.
NASA released a stunning image on Friday showing our home planet as well as the moon from Mars.
