Terrestrial climate models are good and on Mars

The international research team led by William Hartmann of the Planetary Science Institute (USA), found that an extraordinary concentration of glacial formations on Mars concur with the predictions of computer models of the global climate of the Earth.

Terrestrial climate models are good and Mars Dmitri Tselikov Methods of scientific simulations that predict climate change on Earth, have proved their worth on Mars.

The rover found on the "red planet" polyethylene

The rover Curiosity, the second month of exploring the red planet, once again puzzled NASA specialists, sending a new batch of photos of Martian landscape.

One of the photos of the territory under the usual Martian rover sand scientists discovered a strange object. Zoom in; NASA officials saw what looked like a piece of plastic bag. 

Found a rock on Mars with terrestrial features

CAPE CANAVERAL (Reuters) - When scientists selected a stone to test the laser robot on Mars Curiosity, expected to enclose the same raw materials as the stones found in other areas of the Red Planet, but in its place realized that it was more similar to rocks found on Earth.

The stone was chemically more like an unusual rock type found on oceanic islands like Hawaii and Santa Elena, and in continental areas with cracks as the Rio Grande, which stretches from Colorado to Chihuahua, Mexico.

Curiosity log 15 (playing in Rocknest)

Curiosity is already near the area known as Glenelg. On October 2 (Sun 56) arrive at the area known as Rocknest, where there are some small sand bank. Curiosity will spend two or three weeks at this site while making the first sample collection with robot arm systems. As of today, our rover has already surpassed the 400 runs, which is not bad.

The shore of an ancient Martian water channel

The rover Curiosity found some extraordinary features on the surface of the Red Planet that have a strong similarity to the shores of the land waterways.

For example, today's image shows the small ledge of rock that most likely formed by water erosion circulating underneath. The outgoing texture appears to be a sedimentary conglomerate, ie dried debris numerous smaller rocks that stuck together. 

Curiosity found Martian river on mars

New NASA rover Curiosity discovered that, most probably, is the bed of a dried-up Martian flow indicating that the surface of the Red Planet once flowed a stream depth of about a meter.

Photos taken by the rover, found in layers of rock outcrops large, rounded stones. Their shape suggests that the stones were transferred water on the planet's surface over long distances.

Map of the route of the rover Curiosity in the first 43 days of sunshine on Mars ...

This map shows the route of the NASA rovers Curiosity in the first 43 Martian solar days (called solami) on the planet Mars (solar day on Mars is almost equal to the earth - 24 h 39 min) during the execution of the mission on Mars (September 19, 2012)...

The route starts from the contact with the surface of Mars rover, that is from the landing site, later known as the landing site Bradbury (in honor of the American science fiction writer Ray Bradbury, who passed away recently). 

Scientists are developing a platform for landing on the Moon and Mars

Using the lessons learned from the mission "Apollo" and robotic missions sent to Mars, NASA scientists and engineers study the problems and dangers associated with landing on other planets.

The new technology is called "vertical takeoff - a vertical landing." According to the group, operating within the design and technology of NASA's Kennedy Space Center, Florida, the best approach to planning involves landing on a predetermined spot landing area.

Mars formed by the action of liquid water

Discovered in 2005, the clays in the southern hemisphere of Mars are often considered as a proof of the survival of liquid water on the Red Planet at a very early period of between 4.5 and 4 billion years. But the work of a Franco-American team led by researchers at the Institute of Chemistry of materials and environments Poitiers (CNRS / University de Poitiers) [1] questioned this interpretation. In an article to be published on September 9 on the website of the journal Nature Geosciences, they show that these clays are likely to be of magmatic origin. The many similarities between the Martian clays and those of volcanic origin collected on the Murrow atoll support their hypothesis.

Mars's dramatic climate variations are driven by the Sun

On Mars's poles there are ice caps of ice and dust layers with that reproduce to past climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars's north pole to variations in Solar insulation on Mars, the first dated THUS climate Established history for Mars, where ice and dust accumulation has been driven by variations in insulation. The results are published in the scientific journal, Icarus.

UCLA scientist discovers plate tectonics on Mars

Many scientists had thinking plate tectonics that survive nowhere but in our solar system on Earth. Now, a UCLA scientist has discovered that the geological phenomenon, Which Involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars.

"Mars is at a primitive stage of plate tectonics. Gives us a glimpse It of how the Earth early May have looked and may help us understand how plate tectonics on Earth Began," said An Yin, a UCLA professor of Earth and space sciences and the sole author of the new research.

Mars is still an "embryo" of planet

The planet Mars twisted in record time and reached its current size in just three million years, much faster than scientists thought. That rate of formation of the Red Planet could explain that its mass is one tenth of that of the Earth. The study supports a theory more than two decades, according to which the planet remained small because it avoided collisions with what would become the "planetary construction materials", ie other objects in space. The finding is published in the journal Nature.

In the early days of the solar system before the planets were formed, a cloud of gas and dust surrounding the Sun Scientists believe that the planets arose from the accumulation of this material driven by electrostatic energy.

Mars Express reveals complex geological history of Mars

The probe photographed last April Melas Dorsa, a volcanic region south of Valles Marineris canyon.

Captured wrinkle ridges, some faults that cross and surrounded by an elliptical crater ejects butterfly-shaped, with the appearance of being liquid.

Mars Express reveals that Mars has a "complex geological history"

The Mars Express space probe has discovered a wide range of tectonic features and their impact in a volcanic region of Mars reveals that the planet has "a complex geological history." probe photographed last April Meals Dorsa, a volcanic region of southern Valleys Mariners canyon regions located between the Sinai and Thaumasia Plana, reported the European Space Agency (ESA) in a statement.

Surprise! Mars is full of water

According to an article just published in the journal Geology, there is strong evidence indicating the existence of vast underground reserves of water on Mars. The finding, which has come as quite a surprise, it reinforces the idea that the Red Planet can, or could at some point, support life. And it increases the chances of establishing human colonies there in the near future.

The issue of "Martian water" has been debated for more than a century. First, the late nineteenth century, were the famous canals of Mars. Later, in full space age, came the discovery of ancient river valleys and sea revealing a past Martian water-rich surface.

Is this evidence of life on Mars?

Curiosity is expected, the rover is currently traveling to Mars, make a dramatic landing in the crater Gale to mid-August and begin your search for geological signatures of a watery past and friendly to life on this planet. The evidence strong that at some point there were large volumes of water on Mars would be an important step in the search for life on the Red Planet. But ... Have you already been found?

Are we Martians? Scientists Investigate possibility that our DNA comes from Mars

Ominously the movie "Mission to Mars" in the final sequence reveals that an advanced civilization that lived on Mars emigrated from spiritual form the center of the galaxy, but not before his DNA sent to Earth to cause the evolution of life and reach point of being sentient beings-we-we discover that we are them.

 

Similarly MIT and Harvard scientists have launched a major investigation to find out if life on Earth descended from organisms that originated on Mars, reaching Earth in meteorites.

The ESA is evidence that an ocean covered element of Mars

The European Space Agency (ESA) declared today that its Mars Express has provided verification that an ocean enclosed element of the outside of Mars, something that was supposed but remains controversial. The study was based on data provided for over two years by the MARSIS radar, which was deployed on Mars in 2005, and has allowed the experts find that the plains of the northern hemisphere are covered low density material.

‘Danielson and Kalocsa’ the craters on Mars shows how the global climate change

A crater of image on Mars could hold evidence of how temperature evolves on the planet, variable considerably due to changes in the orientation of its axis of rotation. On June 19, 2011, Mars Express said its high-resolution stereo camera to the Arabia Terra region of Mars, photographed the craters Danielson and Kalocsa. The first is called the George E. Danielson, a key player in the development of several satellite cameras shipped in exploring the Red Planet. In this image from Mars Express, Danielson is the crater of the right (north), about 60 km in diameter.

Good omens in the search for antique life on Mars

Structure in the meteorite ALH 84001.The tiny piece of carbon found in meteorites from Mars were formed by the cooling of volcanic emission, were not left there by ancient space germs. This is good news and bad news for astrobiologists.

The discovery in 1996 of carbonate structures in the meteorite ALH 84001, which traveled from Mars to Earth 13,000 years ago, was hailed at the time as evidence that extraterrestrial microbes have ever lived on the Red Planet. However, further studies of both the carbonate structures as tiny bits of macromolecular carbon (MMC) in the meteorite cast doubt on those claims.
