Samantha Cristoforetti the premiere of The Martian: exciting, good Matt Damon – The Messenger

Go now to see even if you do not – but you never know – the unusual opportunity to be in the chair next to an astronaut true, and moreover charge of records, such as Samantha Cristoforetti that not only falls in love with misadventures of Matt Damon – Mark Watney like us mere mortals, but then tells you right away what goes and what does not go in the magnificent and compelling film “The Martian”.



 GRAVITY

 Just as it did with great success, by reviewing sailed criticizes the cult film “Gravity”, regretting also unlikely underwear, skimpy indeed, the heroine Sandra Bullock that came and went in rapid and culottes minicanottiera from space suits when it in fact astronauts as Samantha wear heavy and not very easy and much less sexy clothes over-skin covered by a hundred meters of tubing.

But, we repeat, is from The Martian see why it’s better to Gravity and Apollo 13 put together, with his fiction so probably concrete and closer to us, just thirty years: year 2045. With its scenarios that do not yield to ever solve, at least so far, as the speculation brain Supreme 2001 Odyssey in space or as the recent and even very exciting Interstellar. And then to see why in these days – with a suspicious coincidence benevolently – NASA, consultant of the troupe, confirmed the presence of liquid water on Mars.

In any case, thanks to the Twentieth Century Fox and Italian Space Agency have set up Tuesday evening at Tor Vergata the world premiere of The Martian now in theaters, here’s what happens when you look at the astronaut Matt Damon up there on the screen, in fact, even higher on Mars, since there alongside astronaut Samantha Cristoforetti. And it is having already devoured the first two nights of the novel The Martian champion Andy Weir from which the master Ridley Scott has made into the film forgetting – is to say fortunately – have created Alien and Blade Runner, and maybe instead fished out the theme of the infinite and resilient contention de Duelists, who now are, on the one hand and Matt Damon, on the other, the planet Mars.

Having already read the book, in the case of The Martian, then does not involve the increasingly high risk of being disappointed by the film, which lacks only one octave of drama than the novel. You can accept, as you can fly on two or three licenses in science and technology that the director was granted: the botanical astronaut Mark Watney, abandoned on Mars since believed dead, is apparently not ever subject to lesser gravity of the Red Planet, where It weighs only a third of the Earth. Which is not to say that the Martian sand proceed necessarily only in fits and starts as the moon, where it weighs twice less: a sixth. We would not be blasphemous, but, er er, Corrado Guzzanti had not raised the issue of seriousness in his Fascists on Mars.

STORM

 In addition, the storm wind and sand and rock debris that opens the film, in fact, that it triggers, it could never happen because the depletion of the atmosphere on Mars allows only light breezes which can carry just as fine as talcum powder. Finally, but what is not mentioned even in the novel, there is doubt – then tell the Cristoforetti – a castaway Martian as Mark Watney has to bear heavy consequences – whether or not to come back to Earth – for the display of cosmic radiation the effects of which are still little known among the main sources of concern for those who protect the health of astronauts, including those of the international space station that recently hosted Luca Parmitano (fans of the first hour of the novel The Martian) and the same Samantha.

PROUST, DEFOE AND VERNE

 Gradually the film progresses and Matt Damon overcoming an obstacle after another with astonishing find talented and phenomenal irony, the feelings that surface, far more hold of Proust’s Madeleine, are those of a child absolutely not digital, with only one tv channel in black and white and many books: then, as has been too easily said, the eighteenth-century Crusoe Defoe, but the very late nineteenth-century engineer Smith Mysterious Island Verne. For every obstacle we must think and think again: you can stay like this in life without being superheroes with super powers.

It ‘a film about the future but Scott pushes you always mild in limbo emotions of the recent past, of ‘adolescence, thanks to a loophole portentous: the idea is not his, but the writer Weir but maybe he had not imagined the effects in the film. Just imagine: as the more obvious clichĂ©s, the writer and engineer Weir American, finished masterpiece, could not find a shred of publisher who believed in him and in 2011, as the tenacious protagonist conceived, you autopubblicò the book, which later became a super bestseller.

I WILL SURVIVE

 The trick is to have punished the poor Watney with a single stock of songs in the refuge-prison Martian, or the entire play list and only disco of the 70s and 80s left by the commander of the mission, Lewis, in the film a credible Jessica Chastain . When you read the novel and we do not necessarily the case: yes, the constant self-irony of the protagonist, which puts even posing to Fonzie, is another inspired idea of ​​the writer recovery verbatim from the director and screenwriter Drew Goddard, but then really listen to the hits of Abba in the room and, in the end, I will survive Gloria Gaynor while Watney tries his best not to kick the bucket, it’s really overwhelming. From tears to my eyes, caught between despair and joy. He also feels David Bowie , but not with Life on Mars? (That obvious banality) or Space Oddity, but with Star Man, to accompany a time when the botanist finally seems to have it hit it right.

The film, more than the book in which the description makes less impression, shows mercilessly body emaciated and covered with sores Damon when sol past on Mars become too many and the supplies of food, including the now famous potatoes from him prodigiously grown on the red sand, are about to end. Sol? And ‘the day on Mars lasts 38 minutes in more than here. It seems not much, but those who follow the activities of Earth, for example, the probes on Mars had to really review matters very little space and yet much labor as work shifts, eight hours a day or eight hours per sol Earth?

COMMUNICATIONS LENS

 “The delay in communications with the Earth – then explains the Italian Space Agency astronaut europe, in great shape – it is made well in The Martian, although here too often using irony: there are at least a 20 minute wait between question and answer, and then, in the meantime, any emergencies rapidly changing could not be resolved with the help of the control center on Earth. It becomes even more important to rely on themselves and on their companions. Matt Damon is just, but because of a catastrophe that we hope will never happen, but then the ship’s crew and technical teams on Earth demonstrated the vital importance of teamwork. “

And USA CHINA

 They also show why the Cristoforetti has learned, even with little or no free time and not being forced, after the Chinese English, French, German and Russian. In The Martian, much more than in Gravity, it is hypothesized an alliance between the US and China to save the botanical. That team, American and Chinese together. “In space, the international station, you learn to fully trust each other, to understand each other with a look – says the astronaut when the applause come back on the lights in the auditorium ASI – It ‘a great experience and I would be ready to leave immediately: yes, even to Mars, although the mission would last, with current technologies, at least two years. I do not know if I could get as Matt Damon, a very good actor. I’m not even botany, but the survival instinct, I’m sure, I would invent something. “

EXOMARS

 Meanwhile on Mars are about to leave, between 2016 and 2018, the orbiter and the probe of the ExoMars mission, the European Space Agency (with a leading role for ASI) and della’agenzia Russian space “.
>
 “Already, the first man in space always go robots, so we test materials and technologies and, above all, you collect information – concluded Cristoforetti, besieged more than Matt Damon in a film festival – The Martian Even in these devices have a decisive role: net of scientific and technical issues, is a good movie, exciting, that can push many to follow more closely the issues of space on which depends the very future of humanity that will need resources maybe even traceable on Mars.

A CAMEO IN STAR TREK

 I would also recommend Europe Report, a low budget film but very interesting. I in a film about the fans of Star Trek? Well, the television series I’ve always liked, but I could never play. Yes, yes, something on the web came out, but as I can remotely think of doing a cameo. “

According to the Re / Code, there are no details yet about this new product of Twitter beyond the 140 characters, nor are there no official comment from the company. For years, it has developed a debate on the opportunities that exceeded 140 characters could give users as well as businesses on the platform and advertising. And has resurfaced recently with the interim Jack Dorsey in the role of chief executive, after former CEO Dick Costolo fell under pressure from Wall Street.

In April, Twitter has added the function retweet with comment that fact more space for users to write, to June instead another step forward Twitter offered it by removing the stake of 140 characters in direct messages, those that are exchanged privately between users, marked by ‘icon of the sachet. And there are systems like One Shot, which gives the ability for users to post photos of texts. But are external services at Twitter.

Twitter against Instagram seeks to recovery: he wants to go over 140 characters – The Messenger

Soon the meaning of the expression ‘long as a tweet’ may no longer be the same. The social network would indeed planning to tear down the wall of 140 characters in the post, the main feature since the platform was launched in 2006.

A radical change with respect to the origin, needed to win many users as possible and try to get closer to the big social networks like Facebook which has nearly a billion and a half.

It limit already crossed in recent months by two internal functions of micro-blogging: retweets with comments and direct messages, those that are exchanged privately between users and which are indicated by the sachet. And there are applications like OneShot and TwitLonger that allow you to get around the limit, but they are tools that lead outside of the platform.

The company has great need for a revival, not only economic, but also Popularity: July users were at an altitude of 316 million, far from the numbers of Facebook and Instagram even those who a few days ago has reached 400 million active users per month. One of the most successful moves in recent months was the purchase of the app for video streaming Periscope but evidently failed at the time to drag more subscribers.

While analysts have long argued that the problems of the social network are always the same, that the confusion and lack of access to the flow of tweets. The challenge of the next number one of Twitter will be precisely to make the platform easier to use.

To bring this change might just be Jack Dorsey. After the company he co-founded has turned his back in 2008, as did Apple with Steve Jobs, Dorsey seems to start the reappointment as CEO. The role has been vacant since last July 1, that is, from the scene of Dick Costolo, fell under pressure from Wall Street.

The beginning of the new venture is scheduled for October 22, with subscriptions starting from 7,99 euro per month . It is the revolution of television, we said, and never as in Italy is a revolution that would forever change the TV.

The subscriptions will be different for the different needs of the viewer: the cheapest ( 7,99 € ) includes all content including but on one device of choice (including PC, smart TV or tablet) and only in standard quality.

In recent years, the original productions Netflix have conquered audiences and critics with quality standards far beyond the generalist television we are used to. The acclaimed House of Cards with Kevin Spacey , Orange is the new black , Marco Polo , visionary masterpiece Sense8 of the Wachowski brothers, Narcos , the series that tells “to Gomorrah” the parable of the king of cocaine Pablo Escobar are just some of the original series that Netflix has produced in recent years

But the prospects of Netflix in Italy are really so revolutionary? Potentially yes , because the service made in the USA is a sensational news for a market like ours. But there are also some variables to consider, from the speed of the Internet in our country . There are whole areas where broadband is still a mirage and streaming, especially if you want to enjoy a decent quality, it only makes sense with an acceptable speed. And Netflix, which has its unconscious the vigor of the new, will have to deal with old operators: the sleepy Rai , a Mediaset will sell dear skin and is trying to push the pay Premium and streaming Infinity and Sky , which is the one that has the most to lose right now, because until now the novelty was the pay satellite Murdoch .

Now it is less than a month and the many rumors in recent times are about to end. The word goes to the market and to viewers , who have long been complaining about the quality of Italian television and that from October 22 will have one more weapon to affect the schedules, more and more customizable.

This Minister for Education Stefania Giannini.

Cristoforetti: realistic goal a mission to Mars in 2030
In the aftermath of the announcement of NASA that on Mars there is only ice, but also water salt, the European Space Agency astronaut said he believed “realistic” a mission to Mars to the 30s. It was not particularly surprised by the presence of streams that still flow on Mars, “is one more step in the knowledge of this planet.” “I think going to Mars around 2030 is a realistic goal – saidAstroSamantha – although there are many technical challenges to be faced.” And “if one day I was offered a seat on a flight I’ll go willingly.” Four months after return to earth Cristoforetti Samantha is leaving for the Post Flight Tour, accompanied by two fellow Terry Virts mission (NASA) and Anton Shkaplerov (Roscosmos). Will cross Italy from north to south from 4 to 11 October, engaged in a busy schedule of meetings.

Even the president Battiston go to Mars is not a distant goal. It is not known if it takes place around 2030, however, for the president of ASI ‘these dates are objectives that arises in order to plan future goals. From what has emerged from the missions made so far – he added – is a journey that will be complex and will not be a single trip: it will be made up of many missions approach. ” Surely, he said, “the film makes us think about how we can achieve an ambitious goal in a short time in difficult situations.”

Space: 2016 new mission to Mars, Italy at the forefront – 3bmeteo

After recent discoveries, growing attention and curiosity for the much watched the Red Planet, so much so that as early as next year a new mission , as well of EUR 1.2 billion, will start, with the intent to reach Mars with new probes, designed to find ways of life past or present on its surface.

New mission to Mars in 2016


The new mission will be called ExoMars and organized by the European Space Agency (ESA), including the Italian Space Agency (ASI). The launch of the ExoMars mission is scheduled by January 2016, with a first phase that includes a module in orbit around the planet and a descent module. The latter will be built in Italy, in the plants in Turin of Thales Alenia Space.

2018 then there is a second phase, conducted by ESA and also assisted Russia , during which a rover, called Schiaparelli, will explore the Martian surface and pierce with a drill Italian (brother of the one used by the Rosetta lander Philae in the mission) to a depth of two meters, looking for traces of life. Going down so deep it will take in the information that we know is rich in water, mostly frozen. It will be interesting to study the composition and found traces of chemicals that can be connected to biological phenomena.

Mars water after a new mission Italian – N24G

The mission will license plate and Italy will be named ExoMars , it will be the ASI or the Italian Space Agency, in collaboration with the ‘ Esa , the European Space Agency, a new mission that will aim to explore possible forms of life on the red planet.

On the other hand the president of ‘ Asi confirmed with trepidation: “ Definitely Mars will continue to give us surprises “, then the red planet we still expect a lot of news and breakthroughs, but Roberto Battiston, president of ASI has continued revealing:

That was announced yesterday by NASA is the latest in a long series and essentially tells us that Mars is a place where there is water, although in different ways than we are used to on Earth. We know that most of the water which is located on the planet is frozen and is located in the subsoil, but there is also water that flows and solidifies in limited quantities, but sufficient to change color and surface characteristics ” .

So ExoMars is already ready to go with a lot of project already set for next January 2016, or rather “within” next January, then there will be a second phase of the mission, scheduled for 2018, to be attended by other nations such as Russia.

The launch of the ExoMars mission is scheduled by January 2016, with a first phase that includes a module in orbit around the planet and a descent module. This is a demonstration module built in Italy, in the factories of Turin of Thales Alenia Space.

The drill is the ‘big brother’ of the mission Rosetta lander Philae, the first man-made vehicle ever landed on a comet.

“In light of the enthusiasm and fascination aroused by the discovery of NASA, “said Battiston,” we can say that the ExoMars mission will for the first time on the planet a drill capable of penetrating deep. It will go to take in the information that we know is rich in water, mostly ice: it will be interesting to study the composition and found traces of chemicals that can be connected to biological phenomena. “

“On Mars flowing salt water”: the photos of the Satellite Use Mro – The Messenger

There is water on Mars. During the summer season, that is, when the surface temperature raises the thermometer above the threshold of -23 degrees Celsius, rivulets of liquid water start flowing from the mouth of some craters and oozing from the rock, and then disperse in a fan in a series of channels. The phenomenon occurs at a temperature threshold considered glacial, but that does not prevent the ice from melting, due to the high saturation of minerals which it is associated.
The secret whispered in the ear of President Clinton in ’96 he is finally It was confirmed yesterday by NASA during a press conference announced sensationally titled “The Mystery of Mars is solved.” Water is abundant: in anticipation of the research director of NASA’s Mars Michael Meyer amounts to one million cubic meters, spread out over a very large surface. The composition and origin are still to be discovered, but the mere idea of ​​his presence raises the centennial dream that man will one day live on the red planet, and that can be transplanted forms of biological life that are needed to survive away from Earth.

PRIME MISSIONS

 We have known for many years that Mars had hosted in geologic time huge amounts of water, such as to fill an ocean with a significant portion of the northern hemisphere of the planet. The first images sent to the central NASA Mariner missions in the 70s showed an area marked by gravel beds of rivers dried up, and depressions that once were lakes. We knew that the water had gathered in glaciers at the poles, before breaking up and disappear from the surface. Nine years ago photos taken from the mission Surveyer seemed to indicate a stream that flowed from the rock, and then mark the perimeter of some large boulders. In 2011 high-resolution images back to frame what everyone’s eyes seemed to be sweating water from the rock between the spring and autumn, but the experts were not able to confirm the discovery. Only last April we received the news sent by the rover Curiosity, currently operating on the Martian surface: the night forming small puddles of water on the ground, which then evaporated during the course of the day.

DECISIVE TEST

 The litmus test is about the young geophysicist Lujendra Ojha at the Georgia Institute of Technology in Atlanta, the same who first detected the phenomenon of oozing rock, clearing every reflex and every shade in a lab at the University of Arizona, images of a wall marked by deep flow channels. His research team has put on board the orbiting station MRO a spectrometer which has sounded the surface of a rock from the moment when the first traces of moisture dark have begun to mark it this year, up to the most recent days, in which the ‘shadow had reached its greatest extent. The instrument has detected an abundance of salt hydrates on the surface, which are a clear sign of the presence of water; a kind of ice, whose existence has been confirmed in at least four points of view: the craters Hale, Palikir and Horowitz, and the walls of a canyon large: the Coprate Chasma.

 It remains to understand what gives rise to the water flow. It comes from a deep basin that is the way to the surface with the arrival of warmer weather, or has the effect of a condensing moisture in the thin layer of atmosphere surrounding the planet’s crust, and favored by the presence the salts that the catch?

We must be careful, now scientists say, not to hasten with our curiosity contamination with terrestrial microbes from the environment, thus erasing the signs likely survivors of a lifetime biological past, that its water and minerals could reveal. But now that we know that there will be difficult to resist the urge to pick up the liquid during a subsequent missions and bring it back to Earth so that it can be studied. A new phase of exploration is officially open.

The new iPhone 6S and 6S Plus have already set a record, and that is that of sales in First weekend: 13 million pieces against 10 million weekend debut of the iPhone 6. Already preorders indicated that the new phones would do well, even if the comparison with the first results of the iPhone 6 is not entirely exhaustive , since this time the countries where it was sold straight away iPhone is 12, versus 10 a year ago. Among the newcomers there is China.

The fact is that Apple needs to show a plus sign in front of the sales of this model to Wall Street analysts, partly skeptical about Apple’s ability to go beyond its success (the iPhone 6 reported sales beyond all expectations) and in particular the ability to maintain the pace of growth of the last three quarters, where turnover grew by 30% once on time.

The rise in sales over the weekend is just 30%, but as mentioned the comparison is not complete: will the numbers of sales over the Christmas period to tell the truth, because Apple has simultaneously announced the sale of new iPhone in 40 countries, including Italy, on October 9. The iPhone 6S will cost from 779 Euros for the 16-gigabyte model, 889 for the model to 64 999 for the model 128. The iPhone Plus partirtĂ  6s instead of 889 Euros to get to 1,109 euro for the model to 64 gigabytes. Prices are as iPhone 6 in his debut.

Facebook in the block for the second time in a few days – The Messenger

Facebook bloc. The Social Network in the evening remained inaccessible for just under an hour. And ‘the second time in a few days that Facebook goes haywire.

The trouble began around 21. Then the first of the 22 social network started working again but with some connection problem.

To those who tried to connect the blackout period it appeared an error message that said, “Sorry, something went wrong. We’re working on and we will fix it as soon as possible. “

On the Twitter hashtag” facebookdown “was an instant hit and started a wave of ironic and sarcastic tweet against the company of Mark Zuckerberg.

Liquid water on Mars, the NASA announcement – Media Inaf

mars seasonal cycle In many ways, Mars is a planet very similar to Earth. Length of the day is only 37 minutes longer than Earth’s. The inclination of the axis of rotation, almost identical to our own, produces the succession of all four seasons. As on Earth, on it there are volcanoes, winds, dust storms, clouds, ice caps and canyons. However, today, the planet Mars is a dry and arid. Since the first observations by the probes it is clear that, in the past, liquid water has played a key role in the formation of some geological structures. In recent years, thousands of images captured by the probes in orbit around the planet have shown structures resembling streams of water along the walls of the crater and the slopes of the dunes that vary over time. Evidence that is just to generate the water came just now by the American probe MRO called.

Thanks to the results obtained using the spectrometer and the room on board, the scientists could identify the perchlorates within these streams. Perchlorates are the salts that can form stable hydrates of the compounds. Also, they are able to lower the freezing temperature allowing the water to remain liquid longer and even up to -70 ° C. A sort of natural antifreeze.

The salts are found able to absorb atmospheric moisture to form an aqueous solution. This process could, today, be active on Mars. In a given place, if all of the moisture present in the atmosphere condense on the surface, the layer of ice that would form would have the thickness of a tenth of a hair. For comparison, the Earth’s atmosphere contains ten thousand times more water than that found on Mars. One senses that, to create the structures observed on the surface, it needs a lot more moisture. The solution to the riddle may lie somewhere else. The source perhaps is hidden underground. Liquid water can form after the ice has melted this right here. The simulations, however, show that, at latitudes observed, the presence of ice under-surface is highly unlikely. Another hypothesis sees the sudden escape of liquid water coming from hypothetical aquifers posed in depth. They too, however, are difficult to explain because, from the images, the source of these streams is too high compared to where you expect to find the slopes. At the moment none of these assumptions is, by itself, able to explain what process is behind the formation of these streams of water. The mechanism is probably yet to be discovered.

The thing that seems certain, however, is the strong relationship between these structures and the presence of water in them. The hypothesis is that they are formed because of rising summer temperatures that would favor the formation of liquid water. The latter would not be pure. The combination of perchlorates suggests brackish water.

On Earth, water is an essential element for life. His identification opens up new and fascinating scenarios for the mission ExoMars. With his robot, in 2018, the European Space Agency will land for the first time on the Red Planet. On board will have numerous scientific instruments able also to detect a possible activity of biological origin. Who knows if it will be the time when we will have a definitive answer to the question: is there life outside of Earth?

iPhone 6S from 9 October in Italy, record sales – Webnews

It’s a Monday of celebration, the one for Apple after the first weekend of official sales of the new iPhone 6S . The Cupertino company announced, in fact, share records for infants smartphone: well 13000000 of units sold. It is now preparing the second round of distribution, that will touch the last ‘ Italy from 9 October . Success announced for the California group, which confirms the excellence of the devices, after the previous edition of the beloved iPhone 6.

Analysts had revealed even in the days of pre-orders: with iPhone and iPhone 6S 6S Plus, Apple was on track to beat its historic record in its first weekend of availability. And so it was: the devices have marked share 13 million, compared with 10 in 2014. Now planning the second round of sales , that will visit over 40 countries worldwide, including Italy. So said Tim Cook, CEO of the California group:

The sales of the iPhone and iPhone 6S 6S Plus have been phenomenal, beating any previous sales result during the first weekend in Apple’s history. The customer feedback is incredible, like 3D Touch and Live Photos, and we look forward to bringing the iPhone and iPhone 6S 6S Plus customers to even more countries on October 9.

a lot of the qualities that have made yet another success for the iPhone line, for a line of smartphones really timeless. The iPhone 6S impress the new color gold rose, according to independent analysis already 40% in consumer preferences, but also for the new 3D Touch , the system for detecting pressure on the screen. So Live Photos, animated with photographs included in each shot a few seconds of video, but also the goodness of cameras: one rear 12 megapixels and particularly sensitive to low light conditions, followed by the 5-megapixel front, complete with a flash Retina. Continue, then, with the power and energy efficiency of the new A9 processor, but also with the reinforced body and very resistant, as well as to test these days, aluminum series 7000.

The new iPhone 6S will be available for purchase through the official Apple website, Apple Store and authorized dealers. In addition, for Italy it will be provided for the now traditional solutions of operator TIM, Vodafone and Three, the details of which are currently not yet known. Among the other countries where smartphones will be available from October 9, they are listed Andorra, Austria, Belgium, Bosnia, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, Finland, Greece, Greenland, Hungary, Iceland, Ireland, Isle of Man , Latvia, Liechtenstein, Lithuania, Luxembourg, Maldives, Mexico, Monaco, Netherlands, Norway, Poland, Portugal, Romania, Russia, Slovakia, Slovenia, Spain, Sweden, Switzerland and Taiwan. The next day, the devices will be available in Bahrain, Jordan, Kuwait, Qatar, Saudi Arabia and the United Arab Emirates, while the 16 will start the distribution in India, Malaysia and Turkey.

“On Mars flowing salt water”: the discovery of the satellite Use Mro – The Messenger

flowing liquid water on Mars. Are tiny streams of salt water that appear periodically, leaving dark streaks whose origin was a mystery until now. The test, published in Nature Geoscience, comes from American satellite MRO (Mars Reconnaissance Orbiter).

This is the first evidence that proves the existence of a water cycle on Mars, “said Enrico Flamini, scientific coordinator of the Italian Space Agency (ASI). To provide it is the group of the Georgia Institute of Technology led by Lujendra Ojha. This is certainly not the water channels in 800 assumed by Giovanni Schiaparelli, but ‘streams’ seasonal with traces of salts that form only in the presence of water. More details will be revealed by NASA to 17.30. The American space agency has called a press conference in which will be unveiled at the James Webb Auditorium in Washington. The event will be broadcast live on NASA Television and the agency’s website.

To take part there will be stars of the first magnitude as Jim Green, director of NASA’s Planetary Science; Michael Meyer, lead scientist for the Mars Exploration Program; Lujendra Ojha at the Georgia Institute of Technology in Atlanta; Mary Beth Wilhelm dell’Ames Research Center of NASA in Moffett Field, California, and Georgia Institute of Technology eAlfred McEwen, principal investigator for the High Resolution Imaging Science Experiment (HiRISE) at the University of Arizona in Tucson.

Lujendra Ojha, one of the leading experts who will attend the press conference, in 2011, when he was only 21 years old, he left astonished the whole planet after revealing images of craters on Mars that “they could show proof that salt water liquid flowed on Mars during its warmest months. ” The study was then published in the prestigious journal Science. The article was written in collaboration with Alfred McEwen. The minds of many now flies because Ojha said that if there was indeed water on Mars, there could also be some form of life.
