A new study reveals that the Hellas impact basin on Mars once contained a number of ephemeral lakes, or lakes that are usually dry but fill up with water for brief periods of time.

Boniswa Khumalo PARIS — The crust that encases rocky planets and makes possible the emergence of life took shape on Mars earlier than thought and at least million years sooner than on Earth, researchers said on Wednesday.

Water is considered to be an essential precursor for life, at least as we know it. Mars was once much more Earth-like, with a thick atmosphere, abundant water and global oceans. Up to now, mathematical models have suggested that the solidification of the Red Planet took up to million years.

The new study tackles the question by examining a chunk of Mars that streaked into the Saharan Desert and was discovered in The Black Beauty meteorite weighed grams when found. The researchers secured 44 grammes of the precious space rock, and crushed five -- enough to extract seven bits of zircon that could be used in experiments.

According to a more recent model, planetary growth unfolds more quickly and is fuelled by so-called "pebble accretion", the layered accumulation of particles measured in centimetres and metres that are loosely bound with gases.

So you want to go to Mars? Getting there is hard, but surviving on the Red Planet is harder. The new timeline suggests that something similar may have happened on our planet, but only after Earth was "reset" by the giant impact that formed the Moon about 4.

Mars is thought to have a dense metallic core with a radius of about 1, kilometres, consisting primarily of iron, nickel and sulphur. The core is surrounded by a largely dormant mantle -- some 1, km thick -- made mainly of silicon, oxygen, iron and magnesium.

Finally, the crust averages about 50 km in depth, with a maximum of about km.A new study about terraforming Mars finds that it's not possible to transform the planet into a more habitable place for humans using today's technology. e-news; To study quakes on Red Planet,NASA’s newest Mars lander.

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury. In English, Mars carries a name of the Roman god of war, and is often referred to as the " Red Planet " [14] [15] because the reddish iron oxide prevalent on its surface gives it a reddish appearance that is distinctive among the Surface pressure: (–) kPa, atm.

Mars may have liquid water—a huge lake nestled under the ice cap at the planet’s southern pole, researchers report today (July 25) in Science. Planetary scientists have debated for decades whether the Red Planet has liquid water, usually discussing the possible presence of small amounts that.
