Nexus 5X and 6P, new Chromecast Pixel C tablet: all Google ads – 01net

After Apple, who held the media fire since the beginning of September, it’s time for Google to monopolize the attention of the small world of high tech. This Tuesday, September 29 at 18h, French time, the US giant will hold a conference – you can follow live on 01net.com – during which he is expected to present new smartphones, new mobile OS and new versions of its Chromecast . You can also follow the live ads on 01netTV with input from experts in writing.

Meanwhile, little review details of what should be presented tonight in a few hours of high mass Android world.

Android Police – Nexus 5X

Two Nexus, which we know almost everything

This n? is not a Nexus Google is expected to unveil tomorrow night, but two. Two new smartphones, many details are already known. Notably known to be called Nexus 5x and 6P

The 5x in brief

-. It should propose a slab of 5.2 inches, 4.95 inches cons for the Nexus 5. Although larger, it will always offer Full HD resolution

-. This smartphone is also expected to gain power. It is given to adopt a Snapdragon 808 supported by 2 or 3 GB of Ram. – Storage side, it could offer only two capacities, 16 and 32 GB …

– It should also include a fingerprint reader, because this kind of sensor will be integrated in the new version Android and Android will certainly secure Pay, Google’s payment system.

– The Nexus 5x should also adopt a 13 megapixel sensor for the rear camera and 5-megapixel on the front. It remains to see how Android will manage this new strike force …

– Since the Nexus are reference devices – they are supposed to indicate the direction that Google intends to upgrade its ecosystem – it seems likely that Nexus features a 5x USB Type C.

– Finally, price aside, the latest rumors indicate an entry price to 399 dollars

The Nexus 6P laser …

We already know almost everything 6P … Blame leaked what appears to be the presentation for the press …

– It narrows the screens! After the Nexus 6 and six inches, the Nexus 6P would be equipped with a 5.7 inch screen – always a PHABLET so, that would offer a resolution of 2560×1440 pixels.

– The successful Snapdragon processor would be the 810, with 3 GB of RAM, all would be powered by a battery of 3450 mAh.

– camera side, it could carry a 11 megapixel sensor on the back and 7 megapixel front …

– He too would have a fingerprint reader.

– Available in four colors, the new metal case contains 32, 64 or 128 GB and should be sold from 499 dollars …

Android 6 Marshmallow

The successor of Lollipop will may not be available tomorrow evening, however, it is likely that knows its official release date. Android 6.0, which was announced at the Google I / O in May, however, should not take too long to arrive on smartphones and tablets “eligible”.

The question now is whether, like Apple, Google has kept some new features under the elbow that would be closely linked to the two new Nexus.

One or two Chromecast

If Apple has its Apple TV, Google has its Chromecast. It could be also that the US giant will soon pass the plural and has two HDMI key

A new generation

-. One of which we told you about it some time ago already, which would introduce a new design, rounded, with Wi-Fi faster (802.11 ac)

-. This Chromecast, which always used to stream the photos, movies and videos on their television, should be accompanied by a new application. It should, according to 9to5Google , to find more content to stream their TV.

– The price is unknown for now but hopefully it will remain the same, 35 euros.

A Chromecast for sound

The other Chromecast would be new and could be dedicated to audio.

– This is again 9to5Google , which lifted this information. Chromecast Audio function as his elder but would connect to a speaker or stereo through headphone jack (3.5mm)

-. The launch of this new product could be an opportunity for Google introducing a family package for his service Play Music All Access. This package, which would cost $ 15 a month would allow six people to connect to each their own.

To find out if these leaks and indiscretions are true, just follow the keynote live on Google 01net.com 18h from tomorrow Tuesday, September 29.

A flaw in WinRAR highlights the insecurity of this software – 01net

Reporter

If you are part of the 500 million WinRAR users worldwide We urge you to redouble attention. Security researcher Mohammad Reza Espargham has unveiled a zero-day flaw deemed critical in the latest version of the file compression software (5.21). It allows to remotely execute any malicious code.

This vulnerability only applies to self-extracting archives SFX say. When creating such an archive, you can insert HTML in the “SFX – & gt; Advanced SFX options … – & gt; Text and icon – & gt; Text to be displayed in the SFX window “. This code is automatically executed when the user clicks on the archive. A malicious person could use this flaw to cause the user automatically downloads and executes malicious code without him noticing. Here’s a video demonstration.

However, this demonstration has completely left marble WinRAR developers, who believe that self-extracting archive is primarily an executable, so by nature a risky file. Moreover, they explain that it is already possible through the official WinRAR commands, incorporate any executable in an archive and have it run automatically and in the background during extraction. It is even possible to download an executable from the web.

A hacker could therefore already broadcast internet corrupted archives without the user can realize it without having to go through an HTML code. The developers advise users “not run .exe files, whether or not SFX archives only if they come from a reliable source” . This suggests they do not count plug the flaw discovered by Mr. Espargham. In any case, it’s always good to know that the SFX WinRAR archives are “vulnerable by design”

Nexus, Android, Pixel C … Chromecast upscale replica of Google to Apple – Challenges.fr

While all eyes are worn on the eternal battle between Apple and Samsung in the market for smartphones and tablets, Google once again calls in part by introducing a new range of high-end smartphones, a new convertible tablet and a new TV dongle Chromecast.

The US giant has tried somehow to do the show Tuesday, September 29 in San Francisco, without the talent of Tim Cook and Apple teams. Over an hour of very boring ads (in the version broadcast streaming anyway)! And yet launched products were enough to make up the atmosphere. Especially as the “Event” Google almost met all the ads from Apple during his keynote last September. The Mountain View group sought to provide a rival for the various products launched by the firm at the apple.

First two smartphones Nexus: 5X, signing the largest LG back in partner manufacturers and 6P, designed by the Chinese giant Huawei and number 3 market. Two devices that take over the Nexus 5 and 6 and who have in their sights the iPhone and the iPhone 6S 6S Plus.

Both phones are equipped with a fingerprint reader to identify and secure payments, a 12.3 megapixel camera on the rear (5 megapixel front) and ship the new payment system of Google , Android Pay. They rotate both Android Marshmallow 6.0, the new version of the Android operating system will be available from next week. And finally, they have greater autonomy than 30% over previous Nexus 5 and 6.

The iPhone 6S in the crosshairs of Google

Technically, the 5X is equipped with a full HD (1.920×1.080 pixels) 5.2-inch, u n Qualcomm Snapdragon processor 808 hexa-core 2GHz with 2GB of RAM and Adreno 418 GPU, capacity 16GB or 32GB. Note that the camera uses the technology of LG G4 laser autofocus. Its price starts at 379 dollars for the 16GB version. 6P meanwhile is equipped with a Quad HD display (2.5560×1.440 pixels), a 810 Snapdragon processor, 3GB of RAM, a laser autofocus. Starting price? $ 499.

Both devices are already available for pre-order in the US, UK, Japan and Ireland. They will be other countries next week, assured Google .

By renewing its range of smartphones, Google intends to confront the best- sellers market that are the iPhone and iPhone 6S 6S Plus (Apple announced having sold over 13 million copies worldwide in just three days) and the Galaxy S6 Edge and Edge + Samsung. The objective is to address the segment of high-end, and with very competitive smartphones and at prices much more affordable than competitors … the United States. “We pay attention to what users worldwide have high quality smartphones at affordable prices,” said Sundar Pichai, head of products and future boss of Google. European rates are however significantly less interesting: 479 euros for the first model Nexus 5X and 649 euros for the first model Nexus 6P. (up to 799 euros for the 128 GB!).

Google does not stop there. The American giant has also invited on the ground tablets with its pixels C, with a 10.2 inch screen, the resolution 2.560×1.800 pixels (308 pixels per inch), 3 GB RAM and an Nvidia Tegra processor X1. Unlike previous models (Nexus 7 and 10), it is the first Android tablet made entirely by Google itself. With a keyboard that loving without a tripod, it is the field of hybrid products and displays a very professional functionality to come defy the Microsoft Surface Pro Pro and the new iPad presented by Apple in September. Its original price is $ 499 (32 GB) which must be added $ 149 for the keyboard. A price below 799 dollars an iPad Pro.

Next Gen Chromecast

The third Google’s answer to Apple focused on the television market with its new dongle Chromecast . This box plugs into your TV’s HDMI connector and can transfer content from a smartphone or tablet and access the application store online Google . Unlike the previous, the new model design changes (round) and color and displays a Wifi faster throughput. It also gives access to video games and streaming is also available as audio version for converting an old channel or enclosure product connected (via jack 3.5 mm). The latter provides access to Spotify and Deezer, in addition to Google Play. Both products are available from Tuesday in about 17 countries at a price of 35 dollars each (39 euros in France).

These different ads obviously have not convinced everyone. For the analyst Werner Goertz Gartner, quoted by AFP, outside the pixel C, “everything else is a little catch up. I was expecting a little more fuss” …

“At around 1 am, on the night of Tuesday to Wednesday, a migrant was found dead by an agent Security, he was hit by a freight shuttle “on the site of the Channel Tunnel, said the prefecture. The victim is a “man aged about twenty years Eritrean origin,” the source said.

There was “no impact on the operating cash flows of tunnel, “said in a Eurotunnel release that” deplores the accident which unfortunately confirms that any attempt to cross the Channel illegally entails considerable risks. “

According to the count of the prefecture, between 3000 and 3,500 migrants, mainly from East Africa, Afghanistan and Syria, are in the Calais harbor area hoping to reach England, which they consider an Eldorado. By counting the clandestine present in a Grande-Synthe camp, about forty km from Calais, about 4,000 migrants in the region.

Nexus, Android, Chromecast: What is expected of the conference Google – Le Figaro

VIDEO – Google held Tuesday evening a large reentry conference. The opportunity to present its new Nexus smartphones and a tablet for professionals.

With Didier Sanz, special correspondent of Le Figaro in London

Google is back. The American giant of the Web Tuesday night held an event dedicated to Nexus, its mobile range, and Android, its mobile operating system.

● Two new Nexus smartphones

Google introduced two smartphones Tuesday night. One of them, called “Nexus 5X” is in collaboration with the South Korean manufacturer LG, already causing the Nexus 4 and 5. For the second model, the “Nexus 6P ‘s Google is associated with the manufacturer Huawei. This smartphone has a large screen of 5.7 inches diagonal (14.5 centimeters). This is the first time that Google is working with a Chinese company. The latest model of the Nexus, the Nexus 6, was produced by Motorola. The company, owned by Google between 2012 and 2014, has since been sold to Chinese manufacturer Lenovo.

● A new version of Android

Both new Nexus smartphones are equipped with Android Marshmallow, the latest mobile operating system from Google. Among its new features, the software is able to manage the fingerprint readers, a very popular feature of smartphone manufacturers. Marshmallow Android will be available for all recent Android smartphones next week.

● A Chromecast for audio

Google also presented Tuesday night a new version of Chromecast. Launched in 2013, this small USB key plugs into the television and allows you to easily distribute online content, eg a YouTube video or Deezer playlist. Google has sold 20 million worldwide. Tuesday night, he also unveiled a new Chromecast dedicated to music, which plugs directly into an enclosure. In France, these new products will be sold at 39 € at FNAC, Darty, Boulanger and Saturn.

● A tablet for professionals

More surprisingly, Google took this conference unveiled a new tablet. Dubbed Pixel C, it belongs to the pixel range, which meant far laptops. The device has a removable keyboard to seduce a professional clientele, like the Microsoft Surface tablet or iPad Pro, presented by Apple in September.

Seven things to know about Mars to shine in society – FranceTV info

By Benedict Zagdoun

Updated 30/09/2015 | 6:04 published on 30/09/2015 | 6:04

She is Life on Mars? The hope of one day finding a living organism on the red planet grows with every new scientific discovery. One near certainty of scientists: that life could be discovered in the Martian subsurface. The surface of Mars is far too inhospitable.

While 225 million kilometers from our planet, the Mars Reconnaissance Orbiter and Curiosity robot, sent by NASA, continue their mission exploration, FranceTV info you summarizes the seven major discoveries about our distant neighbor.

1 And amid flowing water

This is the latest discovery dated. And for the most fascinating hour. NASA made the announcement Monday, September 28th. Liquid water flowing on Mars. The channels running along cliffs located at the equator of Mars. They can measure up to hundreds of meters long and five meters wide. They appear only during the warmer seasons, at -23 ° C, and disappear when the temperature drops.

Channels streak the soil of Mars, on a photograph taken by the Mars Reconnaissance Orbiter January 14, 2011. (NASA / REUTERS)

This phenomenon has been observed for the first time in 2011 by the US probe Mars Reconnaissance Orbiter. The flowing liquid is not quite water but brine, a saturated aqueous salt solution.

“We have not seen the water flow . Do not imagine streams. There are very, very little water, “ tempers planetary scientist François Forget, director of research at CNRS and a specialist in March, told FranceTV info. ” The traces, lines that we see take several days to form. Instead of flowing water is a simple progressive humidification, advancing little by little. ”

“The likelihood of microbial life below the surface of Mars is very high,” concludes, however Alfred McEwen, American researcher and head of the main system imaging (HiRISE) on board the US probe.

2 On the Martian soil, salt changes the ice water

The American robot Curiosity has detected the presence of salt in Martian soil. Specifically calcium perchlorate. This substance has the ability to absorb water vapor in the atmosphere. It lowers the point of freezing water, which remains liquid despite the cold that prevails on the surface of Mars. The scientists who analyzed the data collected by Curiosity published their findings in April in the journal Nature Geoscience.

When night falls on Mars, part of the water vapor in the atmosphere condenses on the surface of the Red Planet and frost. Calcium perchlorate in the soil mixes with the ice that turns into brine. And, Mars being porous soil, the water infiltrates into the ground.

3 From the glaciers hidden under dust

Glaciers belts around the red planet, in the northern hemisphere as in ‘southern hemisphere. Radar observations of Mars Reconnaissance Orbiter prove it. This is water ice, not frozen carbon monoxide, as there is also on the red planet.

These glaciers remain under a layer of Martian dust. And volume is impressive: about 150 billion cubic meters. What March cover with a layer of ice 1.1 meters. This huge reserve of ice water was identified by Danish researchers who published their analysis in the Geophysical Research Letters . It was summarized on the blog of The Obs Time Space, in March.

4 Traces of a giant Lake …

Curiosity on Mars discovered traces of what was once a freshwater lake. Mount Sharp, which rises to 5500 meters in the middle of Gale crater where the robot landed, consists of successive sedimentary deposits, as shown in the samples taken by the robot during its ascent. But “this type of deposit is formed when large amounts of water flow along the crater” and “join stagnant water to form a lake,” explain academic Copenhagen in an article published in April in the journal Nature quoted by Le Point.

There was ” a large lake spanning 155 kilometers, maybe even a series of lakes, “ says Michael Meyer, head of the Mars Exploration Program at NASA, taken by The World in December 2014. tank “has existed for millions of years, the time to form, and to dry meanwhile, accumulate enough sediment to form Mount Sharp “.

The Curiosity of boreholes have revealed clay minerals. These suggest an interaction with water. The also found sandstone also appears similar to that existing in the rivers on Earth, which suggests that a river flowed into the lake, the researchers wrote in Science in December 2013, information relayed by The World.

Even better, the analyzed rocks contain traces of carbon, hydrogen, oxygen, nitrogen and sulfur that “provide the ideal conditions for an elementary microbial life” . On Earth, tiny forms of bacterial life thrive in similar conditions.

5 … and more ocean than the Atlantic

The analysis of the Martian atmosphere with two telescopes – one European based in Chile, the other American in Hawaii – has delivered another secret. In the distant past, Mars was a wet planet similar to Earth, with lakes, rivers that carved valleys … and an ocean that was to cover 19% of the red planet. In comparison, the Atlantic occupies 17% of the surface of the Earth. Scientists have described the landscape in March in the journal Science .

Mars had enough water to be completely covered to a depth of 137 meters. But this water most likely formed an ocean that covered half of the northern hemisphere of the planet. There are some places reached depths of over 1.6 km. Given its geology, this part of Mars has long been regarded by scientists as the most suitable area to contain an ocean.

6 The soil contains nitrogen, essential for life

Curiosity collected rocks in several places of the red planet. These samples were analyzed by the laboratory mini-SAM (Sample Analysis at Mars) on board the Mars rover. The molecular study, unveiled in March, showed the presence of nitrogen. However, this gaseous body is essential to all known forms of life. It is a key part of larger molecules such as DNA, the genetic code of living beings

There is no evidence, researchers temper, that these nitrate molecules derived from a living organism yet. These nitrates are old and have been the result of non-biological processes, such as the impact of asteroids or lightning on Mars in the distant past. But this discovery provides further evidence that Mars in the past met the conditions for the existence of life.

7 Disturbing emissions of methane

Since the Gale crater in which it landed in August 2012 Curiosity has surprising detected methane emissions. In very small quantities but regular. This gas originated in part from the decomposition of the dust of the Martian soil under the influence of sunlight and organic materials carried by meteorites. However, for two months, the measures of the spectrometer and the onboard laboratory have shown that methane escaping from the ground where he was therefore produced.

Scientists of the Mars mission failed to determine The origin of this gas, as they explain in their work published in December 2014 in the journal Science . They can not tell if this methane is biological or geological origin. Methane and organic molecules found in samples collected in the rock by the drill Curiosity may nevertheless they think “indicate the presence of a past or present microbial life” . On Earth, methane comes into effect in 95% of microorganisms.

Officials from NASA have further penetrate through the secrets of Martian exploration missions planned in the next five years. Pending the first manned mission to the red planet, the US space agency plans in the horizon of 2030, at the earliest.

Mars discovery that changes the liquid salt water? – Point

After great drum rolls which she has the secret, NASA said Monday it has tangible evidence of the actual presence of liquid water on Mars. What needs to think and what implications for research of a possible extraterrestrial life? Astrophysicist Francis Rocard, head of solar system exploration at CNES, decrypts, for The Point.fr, the real implications of this discovery.

The Point.fr : What the researchers observed precisely?

Francis Rocard: In 2011, the dark discharge, correlated to a seasonal effect, had been spotted on the slopes of Mars. Already, the idea had germinated in the minds of everyone that this could be related to a liquid water phenomenon. But still had to prove it! We were then told at the time that if we found salt, that would be proof. Now, with the instrument CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) of the probe MRO (Mars Reconnaissance Orbiter), the authors of the study released Monday identified perchlorate salt hydrates, that is to say waterlogged water. Hence the conclusion reached now is that, yes, it was rather a phenomenon that takes place in the presence of liquid water. First, because there is a correlation with the season: this happens when it’s hot and not when it is cold. And second, because we are dealing with salts that flow, which is consistent with liquid phase transition, knowing that these salts do not freeze to a temperature of – 23 ° C. However, this is not a direct proof of the presence of liquid water is only indirect evidence …

However, can we consider that it s ‘is d ‘ definitive proof?

Yes, this is an almost definitive proof, the only downside being that we have not formally observed in liquid phase water. It was, in short, observed hydrated salts in a consistent thermal context with the fact that it passes the liquid phase.

D Where this water can it come?

There are not really any answer to this question. However, you begin to master the history of water on Mars. We know that there are, in frozen form, almost everywhere, even if the concentrations in the soil are not necessarily well known. Think we have a ice accumulation on the soil starts to move in the liquid phase when it gets hot is a diagram that takes the road. In other words, it is not liquid water that comes out of the basement, as it triggers uniformly throughout an area and it is not located at a water seepage liquid.

The authors of study evoke an absorption of moisture in the ‘ Martian atmosphere, so tenuous it may be. Qu ‘do you think?

It is also an opportunity … It is true that there is a little water vapor in the Martian atmosphere, but really very little.

What are the real implications of this discovery for the search for life on Mars?

This is not an easy question. I think we will have now “digest” the news. Of course, liquid water is a prerequisite for the emergence, the emergence and preservation of life. It’s a certainty. Nevertheless, we are dealing with phenomena that are extremely liquid episodic, seasonal, and finally quite rare. So be careful enough. In addition, we speak of hydrated perchlorates, salts that are not very friendly for the living, although some chemists have ever imagined bacteria that can live in high concentrations of perchlorate. But anyway, for many reasons (radiation, cold, soil acidity, etc.), the environment on Mars today is hostile. So if life exists, it may be that damn resistant bacteria …

Finally, for you, s ‘is it d ‘a fundamental discovery?

I wonder about its importance. In the sense that we will see whether this discovery will influence the Mars exploration strategy. Will there be a consensus in the scientific community to say that, yes, it is very important. In 1976, the Viking exploration program sought a present life on Mars and gave no results. After that everything has switched to the search for ancient life dating from 3.5 to 4 billion years. Now, what are we going to decide to do? Change strategy? Do both in parallel? This is something that we will watch closely …

Phone Nexus, Pixel C tablet, Android Marshmallow … the main Google ad – The World

Android 6 . Nicknamed “Marshmallow,” the new version of the Android operating system, which equips the majority of smarpthones in the world, will be available from next week. The update will, however, be available until later on most terminals, depending on the operators. – Only users of tablets and Nexus phones will initially concerned

Among the main new in this version, security updates, improved management of notifications, optimization of the use of the battery and the integration of Google Now system directly into applications. Another important development: it is now possible to manage a case by case the access permissions to the personal data of applications, a feature that already exists on Apple’s iOS

Nexus 6P. This high end phone, built by Huawei will be the first metal Nexus phone. Sold 500 euros, with a 5.7 inch screen, it will not be available before the end of October – and pre-orders will not be opened initially in France. This phone uses a USB-C port to recharge, which will require a special cable. – In return, Google says it is charging twice as fast as its main competitor, the iPhone 6 Plus

Nexus 5X. Cheaper than the 6P (380 euros), this phone is intended as a “updated” version of the Nexus 5. Slightly less powerful than the 6P, it is also equipped with a slightly smaller screen (5.2 inches) but also has a USB-C port.

Pixel C. This upscale tablet (600 euros) recalls both the Microsoft Surface tablet PC and iPad combined pro Apple. Compatible with a detachable keyboard (150 euros), this powerful tablet 10 inch runs Android and is presented as an intermediary between the laptop and the conventional tablet.

Chromecast 2 and Chromecast audio. These two small connectors, sold 35 euros each, are used to stream video on almost all screens (for the first) or music on all kinds of speakers (for the second), broadcast by a Android device. Both versions benefit from improved wireless data rate.

A “family” subscription to Google Music. Direct Response to the family membership of Apple Music, the Google music streaming service will soon have a subscription can be used by six people from the same household, for 15 euros a month, against 10 euros for individual membership.

Google launches new smartphone Nexus and Nexus 5X 6P – 01net

This is the end of the suspense. On the occasion of his re-entry high mass held in San Francisco, Google recently formalized its new smartphones. After a Nexus 5, 5 inch format, launched in 2013 and a Nexus 6, real PHABLET 6 inches, marketed in 2014, the Internet giant is launching two new models in 2015, Nexus and Nexus 6P 5X respectively equipped with 5.2 and 5.7-inch screens!

5X Nexus, a little larger than the Nexus 5

Designed by LG, Nexus 5X therefore comes with a large 5.2 inch screen. With its definition FullHD, it delivers a resolution of 424 dots per inch, although sufficient to the naked eye, but slightly down compared to the Nexus 5.

The smartphone is animated, as we sensed it with a powerful 64-bit processor without Google book Nothing more details. Photo hand, there is a 12.3 megapixel main sensor, Sony’s design and accompanied by a laser autofocus. Photosites with a little bigger than usual (1.55 microns) of this sensor, Google promises more than the average successful pictures in low light. The Nexus also has 5X battery mAh 2700.

Nexus 6P, for lovers of phablettes

More impressive but sporting a 7.5mm ultra thin case, the Nexus 6P, designed by Huawei, is equipped a 5.7 inch screen, a definition of 3840 x 2160 points for a high resolution of 515 points. This screen occupying 74% of the front, borders are pleasantly thin and attractive metal housing while pltôt to the eye.

Not much more information about the processor, but that he, too, 64 bits. In photo, the place of honor goes to selfies with front an 8 megapixel sensor, while at the back, we find the same 12.3 megapixel sensor present on the 5X.

and 5X 6P: Public points

The two smartphones with Android operating Marshmallow (6.0), which brings a lot of new software and feature both a fingerprint sensor for unlocking Google promises particularly fast. And in addition to their common main photo sensor of 12.3 megapixels and 5X the 6P USB connectors feature a latest generation USB-type C.

Both smartphones will be available pre-order in the next hours, from 379 dollars to 5X and from 499 dollars for the 6P. They will be available in October in the United States, the United Kingdom, Ireland and Japan. It will take a few weeks to see these aircraft to land in France.

2030 Mars Odyssey: movie or reality? – L’Express

5 July 2030 Man sets foot on Mars. After decades of research and more than seven months of travel, he finally reached its Martian goal. At least on movie screens or in the dreams of astronauts, who are already put beside the Curiosity robot for posterity, after the announcement of the discovery of salt water on Mars.

In 2010, when Barack Obama spoke of 2035, Buzz Aldrin already urged the US president to keep pace or even accelerate it. The second astronaut to set foot on the Moon soil openly promotes a round trip from Earth-Mars 2018, to length of interviews and books, between two sales Tshirts “Get your ass to Mars “ (” Bring your ass to Mars “, literally).

The US has already managed to put probes and robots, like here Curiosity on Mars … But a human mission is a good deal different.

An astronomical bill

The desire is there, then, but how? “ A mission to Mars, the most difficult to date in terms of technology remains out of reach of most of the players involved,” Judge Jean-Yves Le Gall, president of CNES, even play the role of killjoy. “If we really had to go, it would not be before 2050. Maybe in 2057, for the 100 years of Sputnik!” Quips Jacques Villain, author of Will we one day really on Mars? (Ed. Vuibert, 2011). “We talk about human missions to Mars since 70 years but we ask exactly the same questions in 30 years … There is a lot of fantasy around this issue, but I see no momentum.”

Starting with financial dynamics. “It is estimated between 100 and 300 billion cost of such a mission. This amount is also difficult to gather that acceptance … And this imprecision demonstrates how we are not ripe to do” said Jean-Yves Le Gall. Even less optimistic, Jacques Villain inflates the bill up “500-600 billion.” An astronomical amount that “the first dollar were made by any of five successive US presidents have talked about going to Mars,” the specialist said that “it is the US Congress who vote, anyway” .

But there are some major differences between Barack Obama and his predecessors: the current political climate is dominated by the economic crisis and the ecological emergency. How to make space exploration a priority in this context, without the Cold War background, had whetted the appetite for the Moon of the United States and the USSR? For specialists consulted by L’Express, there is more political issue: the sole interest of such a mission is scientific and is to show that “we know how”.

15 years to achieve a “giant space train”

Hard to sell to public opinion … to provided that, for now, we do not know how. “It would require a disruptive technology”, asserts Jean-Yves Le Gall. And if the discovery of brackish water on Mars, NASA announced on Monday, gave the necessary impetus? Some are already imagining that one could “desalting water dunes to supply drinking a scientific base on Mars,” we read in Liberation.

It is further necessary being able to go to the red planet and back. The SLS rocket being developed could be used, but “it would take another 10-15 years to build a ship,” anticipates Jacques Villain. And what ship … “We will not send six people confined for two years in total, in a Renault Twingo. You have to imagine a remake of 2001 Space Odyssey , a sort of giant space train fitted with artificial gravity, a sufficiently large living area, a kitchen garden, etc. It’s huge! “describes Jean-Yves Le Gall.

Keep the crew healthy

would remain the question of radiation, the need to gain speed to reduce the duration of the journey, the impact such a trip on the muscles and bones of the crew … Not to mention their sanity, in such promiscuity during these two years, when the individual record of 438 days in space.

Would come also the problem landing, the most difficult step of this journey. Countless probes, Soviet, Chinese or American, who paid the price for decades. “The atmosphere is so thin and little known that the behavior of the sensors is difficult to predict,” said the President of CNES. “And ask a probe of 200-300 kg, it’s not the same story that pose a vessel of 10-20 tons,” added Jacques Villain.

A long international cast to negotiate

But the United States keep a step ahead of other players in the race. “Americans have created models … and managed to land their probes, where others have experienced failures. The first man on Mars has a 90% chance to be an American,” predicted Jean-Yves Le Gall . As the actor Matt Damon, hero of the film Only on Mars , which tops the list of paris on the Internet …

This does not prevent American domination of India grow bolder and photograph the Martian surface with its orbiter Mangalyaan since 2014, history to race with China, which itself is the moon. European side, the ExoMars program plans to send an orbiter in 2016 and a probe to the ground in 2018, not to mention private Mars One program that has little chance of success but could help lower the costs of a future human mission.

Not enough to panic NASA, which still calls for international collaboration to go to Mars, just to split the bill. It’s a safe bet that the film production as cast 2030: The Mars Odyssey will be international. But who says collegial decision, said additional diplomatic period! If Mars is a destination rooted in the collective imagination for decades, so it seems unrealistic to expect to see on our screens the film of adventure before 2030 or even 2035. No offense to Buzz Aldrin and Hollywood .

“Life on Mars? This is the question a million dollars “- The World

These new observations, they provide unprecedented evidence on the presence of salt water on Mars, especially compared to your publication May in Nature Geoscience

Yes. Our article and it uses completely different data to identify the presence of liquid water on the surface of Mars. If the attendance has been characterized even in recent geological time, the current presence of water, brines, rested only on essentially theoretical and thermodynamic arguments. On the other hand, coulees [RSL that researchers call for "Recurring slope lineae" recurring dark lines] indicate a seasonal activity fluid, but so far the fluid in question remained unknown, even though water remained the leading candidate.

It does not surprise me they found hydrated salts that form when the water evaporated. But this article provides a direct link between theoretical models and geomorphological observations, which represents an important step in the study of the stability and activity of water on the surface of Mars. Now, indeed, it should be noted that this is not the water that was directly identified, but the effect of the brine and the post-evaporation residue.

Life as we know it on Earth would she have had a chance to grow and persist in such tanks?

This is the question one million dollars. It’s hard to say. On one hand, we do not know very well what are the limits of life in extreme environments on Earth, particularly regarding highly concentrated liquid salts where water activity, that is ie its capacity to be available for possible biological reactions, decreases at very high concentrations. These very high concentrations are nevertheless necessary to maintain stable liquid at very low temperatures to prevent freezing. Therefore the higher the temperature drop, the greater the stability of liquid requires high salt concentrations. It is a fact impossible to avoid.

On the other hand, if life developed on Mars, so she probably had hundreds of millions of years to adapt to increasingly difficult conditions. So for now, there is really no definitive answer to this, but there are other objections to the current presence of life on Mars, as the total absence of carbon. It is therefore necessary to take things with large tweezers …

Is it easy to get drinking water from these brines, for colonization of this planet?

Here in against the answer is yes, in principle. Recondensant and evaporating the water, it is possible to separate the salts and recover almost pure water.
