Earth has at least 1.75 billion years left, scientists have found. That means that Homo sapiens, in the unlikely event that the species will persist all that time, have used up about 0.01142857142 percent of their time on Earth so far.

A team of British researchers has developed a model for determining how long a planet can expect to be within its sun’s habitable zone – the sweet spot just far enough to the sun so that the planet’s water doesn’t sizzle into vapor but just close enough to the sun so that it doesn’t freeze.

The model, reported in the journal Astrobiology aimed at assessing which planets outside our solar system, called exoplanets, might be in that comfortable zone long enough for intelligent life to make its gradual appearance there. In doing so, it also offers a prediction for Earth’s remaining time.

Most exoplanet research is underpinned by one all-important question: “Is this planet habitable?” To answer that question, scientists often begin by asking if that planet falls within the star’s habitable zone, where liquid water, an ingredient thought to be critical for life, could be available.

But just how the bounds of the habitable zone are calculated and plotted has been the subject of much debate in recent years, as exoplanet research now includes not just hunting those planets, but also classifying them.

Researchers, for example, have debated what effect cloud cover might have on the range in which a planet might be habitable. Perhaps, clouds might keep a planet close to the sun cooler than it otherwise would have been, protecting its surface water reserves from evaporation, researchers have proposed.

Still, as the latest paper’s authors note, what is not controversial is that the habitable zone, however it is defined, fluctuates over time. Over billions of years, a star’s brightness increases, and planets once in that sweet spot begin to broil.

“Toward the end of a planet’s [habitable zone] lifetime, steadily increasing stellar luminosity is likely to result in a runaway greenhouse event, which would represent a catastrophic and terminal extinction event for any surface biosphere present on the planet,” write the authors, in the paper.

So, in the hunt for extraterrestrial life, the question, “is it habitable?” is not meaningful without also answering, “for how long is it habitable?”

That’s because life takes a long time to develop – or at least so it seems based on our experience here on Earth. Here, on this planet formed about 4.5 billion years ago, we didn’t get single-celled organisms, called prokaryotes, until about 3.6 billion years ago, and bacteria that could photosynthesize didn’t pop up until 2 million years after that. Fish then turned up about 500 millions of years ago, then insects about 200 million years ago, and then dinosaurs about 200 million years ago.

Humans, following up on the evolution of mammals, birds, and flowers, have spent just 200,000 years on this planet. We are, essentially, the scrubby, ultra-thin tip of an eraser, topping a long pencil of time that precedes us.

All this suggests that good candidates for life outside our solar system must have enough time in their star’s sweet spot – more than 4.5 billion years, it seems – for that life to burgeon.

In search of those planets on which Earth’s life-hunting resources are best spent, the team modeled the expected habitable zone lifetime for seven confirmed exoplanets and 27 of the Kepler telescope’s exoplanet candidates, as well as the lifetime for Earth.

Tesla Motors founder Elon Musk has raised the ante on the rest of the automobile industry, declaring in a recent interview with the Financial Times that his company's self-driving car will be street-ready by 2016.
Google, whose autonomous car has successfully driven more than 500,000 miles and has even accommodated a blind driver, had previously set 2018 as the expected release date for its self-driving car technology. Israeli company Mobileye is the only other to make as bold a claim as Tesla, albeit with a lower-cost system that The New York Times says  "does not offer the autonomy achieved by Google's engineers."
Although Musk has a tendency to talk publicly of far-reaching technological concepts, most notably the Hyperloop, he told the Financial Times that this declaration is "not speculation," but rather an educated guess based on the company's internal development.
There is a catch, however Musk says the car will not be fully autonomous, but will instead offer "a form of auto-pilot' in most situations that would allow the vehicle to take over control," the Financial Times reported.
"My opinion is it's a bridge too far to go to fully autonomous cars," Musk said in the interview. "It's incredibly hard to get the last few percent."
RELATED:Big data roadblocks will slow driverless cars until 20404, analyst says
20 cars that driver themselves
In that sense, Tesla's plans for driverless cars align more with Mobileye's than Google's. Mobileye can automate driving a vehicle that drives "in a single lane at freeway speeds, as well as identifying traffic lights and automatically slowing, stopping and then returning to highway speeds." Its benefit, compared to Google's driverless car, is that it costs just a few hundred dollars to outfit a car with the cameras that make up the Mobileye system.
The Financial Times also notes that Google has had difficulty finding a manufacturing partner willing to adopt its technology, reportedly out of concern for safety and liability.
"Mr Musk's rejection of the idea of a fully autonomous car, however, was the latest sign that Google has had trouble finding partners among established carmakers to bring its technology to the road," the Financial Times reported.
Despite the increasingly competitive race to put the first driverless car on the road, others are less optimistic. Sheila Brennan, IDC's program manager for product lifecycle strategies, said in March that issues involving handling the implicit data and legal issues involved with autonomous cars will keep them largely off the road until about 2040.

Hampton Hotels Santa Clarita - Yes, There’s a New iPhone. But That’s Not The Big News

The big Apple news this week might seem to be the new iPhones. But truth be told, the bigger news is iOS 7.

This is the free software update for iPhones (iPhone 4 and later), iPads (iPad 2 and later) and iPod Touches (fifth generation). It’s a radical, huge redesign. Its master architect was Jonathan Ive, the Apple designer who has brought us astonishing hardware designs for many years; now, for the first time, he’s been put in charge of a whole software universe.

The look of iOS 7 is sparse, white — almost plain in spots. No more fake leather, fake woodgrain, fake green felt, fake yellow note paper. It’s all blue Helvetica Neue against white. 

The complete absence of graphic embellishments makes it especially utilitarian — in both senses of the word. That’s good, because whatever button or function you need is easier to find; it’s bad, because, well, it can look a little boring. 

Then again, the new look is primarily visible at the Home screen, where a jarringly different color palette greets you on the Apple app icons, and on the options screen. The rest of the time, you’ll be using your regular apps, many of which will look no different than before.

The look of iOS 7 may grab you or not. But once the fuss about the visuals dies down, something even more important comes into focus: the work that’s been done on making iOS better. The longer you spend with the new OS, the more you’re grateful for the fixing and de-annoyifying on display.

For example, you no longer have to burrow into infinitely nested Settings screens to adjust your control panels. Now you can just speak what you want, using Siri: “Open Wi-Fi settings,” for example, or “Open brightness settings.”

Or, when speaking to your phone isn’t socially appropriate, you can swipe upward from the bottom of the screen to open the Control Center: a compact, visual palette of controls for the settings and functions you’re most likely to need: brightness, volume, Bluetooth, WiFi, Airplane Mode, Play/Pause Music, calculator, camera, and — my favorite — Flashlight. This panel slides in over whatever app you’re using, so you don’t lose your place.

This idea — swiping in from the margins of the phone — also plays out in the new Back gesture. The iPhone doesn’t have a Back button, as Android phones do. But now you can swipe in from the left margin of the phone to go back one screen. It works in Mail, Settings, Notes, Messages, Safari, Facebook and some other apps. It’d be great if worked in every app.

The iPhone has never had a system-wide Search button, either, but here again, Apple has made some strides. The Search screen is no longer off to the left of the Home screens; now it’s above them — all of them. From any Home screen, you can swipe downward from the phone’s top margin to open the Spotlight search screen. 

Reducing steps seems to be a running theme in this release.

To turn on Private Browsing in Safari, for example, you used to have to open the Settings app, burrow around, find the on-off switch, then return to the browser. Now the Private button is right in Safari, where it belongs.

The Camera app has gained a better design. Now you swipe across the preview screen to switch among modes: Video, Slow-motion video (on the iPhone 5s), still photos, Square photos with Instagram-type filters, and Panorama. It’s easy to learn and use, but it does mean that it’s harder to open a photo you’ve just taken for inspection. (Swiping to the right used to make it appear; now you have to tap the tiny thumbnail button in the corner.)

There was supposed to be a password- and credit-card memorizing feature that would make it much easier to buy stuff and fill in forms on the Web, like the LastPass, 1Password or Dashlane apps. And this information would sync across all your Apple gadgets. But it mysteriously disappeared in the release version; Apple says it will reappear in a few weeks, at about the same time as OS X “Mavericks.”

The new iTunes Radio is here, though, and it’s very good. The idea is exactly like Pandora; you choose a “seed” song, performer or musical genre, and it plays nonstop songs in that style. But it’s not as sophisticated as Pandora, and not nearly as powerful as Spotify; on iTunes Radio, you can’t explicitly request a certain song or album by name.

Still, having it built in is nice. For example, you can say, “Play Soft Guitar radio,” or whatever you’ve named your “seed”-based station, to start it up.

As with Pandora, the free version subjects you to a brief audio ad every now and then; also as with Pandora, you can pay for an ad-free version. It’s $25 a year — part of Apple’s existing iTunes Match service.

Siri, over all, is much better. The voice sounds more natural, and you have a choice of male or female. Apple did a lot of work “on the back end,” so that Siri responds much faster to commands. The Siri screens are redesigned to look nicer. And Siri can do more things.

More stuff:

• Internet phone calls. Now free, high-quality voice calls (to other Apple phones, tablets and Macs) are built right in. Apple calls it Audio-Only FaceTime. 

• Carpenter’s Level. The Compass app now has a three-dimensional level in it!

• Auto-app updates. You can opt to have new versions of your apps downloaded and installed automatically, in the background. The App Store app keeps a list of everything you’ve received.

• Today screen. As on Android, there’s a single screen that lists everything that’s happening today: your next appointment, today’s weather, reminders due, whose birthday it is and so on. (Right now, mine says: “It looks busy right now. There are 8 events scheduled, and the first one starts at 8:30 am.”) 

• Smarter Wi-Fi network alerts. If you’re driving, iOS 7 on the new iPhone 5s no longer keeps announcing that it’s discovered new Wi-Fi networks. Obviously, you’re moving too fast to hop onto any of them, so this is a smart little tweak.

• Photos. The app that displays all your photos used to be a single endless scroll of tiny thumbnails. Navigationally speaking, it was really pretty useless. Now it self-assembles into clusters by year, by month and by occasion (based on time and location data). Sooooo much better.

• Maps. Apple still has work to do before its Maps app has anywhere near the quality of Google’s Maps app. Apple’s Maps still can’t give you directions using public transportation, but at least it now has walking directions. And when you’re driving at night, Maps automatically enters Night Mode, in which the map itself is dark gray instead of very bright.

• Global Type Size control. For the first time, there’s a slider that controls the font size in all your apps. Well, all of them that have been rewritten to hook into this feature, anyway. So far, it’s mostly just Apple’s built-in apps.

• Activation Lock. Brilliant, brilliant, brilliant. If some thug steals your phone, it’s worthless to him unless he enters your Apple password. Even if he tries to erase it, even if he jailbreaks it, even if he force-reinstalls the operating system. Thousands of iPhones will not be stolen now, because thieves will learn that they’ll be “bricked” without your password. (To make this work, you have to turn on the “Find My iPhone” feature. Which you should do anyway.) 

There are a zillion other nips and tucks, many of which make you smack your forehead and say, “Yes! Why didn’t they think of this sooner?”

The software is available to download on your existing iPhone, iPad or iPod Touch tomorrow, Sept. 18. 

If you decide to install iOS 7, as you learn your way around the new system you’ll stumble across all kinds of handy features and techniques. But without any further delay, at least make these two features part of your new routine: Control Center (swipe upward from below the screen) and Siri’s new settings-changing commands. 

I think you should install it. The structure, layout and features represent some of Apple’s best work. The look of iOS 7 — well, that judgment is up to you.

Hotels In Northern California - European Space Agency Wants to Send a Snake Robot To Mars

Snakes are crafty animals. They can be found slithering in the desert, swimming in the ocean and even flying in the air. But how would they deal with another planet altogether? 

Researchers at the SINTEF Research Institute in Norway and at the Norwegian University of Science and Technology aren't planning to launch the legless reptiles on a spaceship, but they are using them as inspiration for a new type of Mars exploration robot. Aksel Transeth, a senior research scientist at SINTEF, along with some of his colleagues, are conducting a feasibility study for the European Space Agency, examining how a snake robot would fare on the red planet. 

"We started the study back in June and will finish sometime in December," Transeth told ABC News. The study is more like a written report than it is a series of experiments, he said. However, the ideas on paper could make its way into a prototype within a few months. 

Transeth primarily researches how to make snake robots more efficient on Earth in search and rescue missions. "Biological snakes can climb rocks and slide through small holes," he said. "Imagine if you could have a snake trained to find people in fallen down buildings." 

It's because of a snake's ability to get past almost any type of obstacle that makes it useful. Howie Choset, a professor of robotics at Carnegie Mellon University, said that there are many places that current rovers can't reach. "The snake robot could travel to cliffs and look underneath overhangs," he said. "It could find a crevasse, crawl down it and extract a sample, which itself could tell us how Mars evolved as a planet." 

But Choset, a snake robot researcher himself, said that getting to that stage is still a long ways away. "There are a lot of challenges that we still have to address," he said. "We're still having a hard time figuring out how to make these robots work in bumpy and highly confined spaces here on Earth." 

"It could tell us how Mars evolved as a planet."

At this point in the feasibility study, many aspects of the snake robot are still up in the air. Mars is colder and has less gravity than Earth, both of which could impact how the robot behaves. But one thing that Transeth is almost certain about is that the Mars snake would be a companion and not a robot left to explore the planet solo.

"It takes energy to get from point A to point B," said Transeth. "I think a tethered solution might work better so it doesn't need its own power supply. But this is just speculation." 

The ESA plans to send its own rover, ExoMars, in 2016 and 2018. NASA, while still working with Curiosity, is also planning to send another rover to Mars in 2020. 

While Choset is cautiously optimistic about how a snake robot would fare on Mars, he said that there is plenty left for it to do on Earth. "Other applications like archaeology and surgery ... these applications are less out of this world than Mars," he said. "I wish NASA were sending snake robots to Mars though!"

California Vacation Packages - So You've Lost Your Locked Smartphone Or Tablet? Here's How To Get It Back

A standout point for me in Tuesday's Apple announcement was that 50 percent of people lock their iPhones. I was surprised it was that high -- it seems every week I say to someone, "Dude, do you really not lock your phone?" My guess would have been closer to 20 percent.

Anyway, I'm grateful that Apple is putting more awareness out there around the importance of locking portable devices. After all, your whole life is on there -- it really should be locked regardless of how many dozens of times you have to key in your PIN each day.

Locking your smartphone or tablet creates a problem though. How do you get it back if you lose it?

The one and only time I've lost my old school pre-smartphone phone, someone found it and handed it in at a local police station. An officer there just went through my address book and called the one marked "Mum and Dad". I got the phone back the same day.

But if it's locked -- that's a different story.

Old school

The simplest thing to do here is to get your contact information on your lock screen. That way when someone finds your phone they see the contact information and call you on an alternative number.

When I discussed this on Twitter, generally people weren't happy with that. The preferred option from my self-selecting collection of friendly technologists was that you use the "Find my Whatever" feature offered by the platform and use that.

However, that won't work with Wi-Fi only devices, like my iPad. It will probably work better with a smartphone admittedly, but think about this for a moment. If you've lost your phone, you want this really, really easy. You want anyone just to pick up your phone and get it back to you. A message on the lock screen is the simplest way to do this.

On old school BlackBerry OS 7 phones this has always been a feature. (In fact, you could push it out as enterprise policy to all the devices in your purview.) Weirdly, as we pivoted to current generation post-PC devices this brilliant idea of just having the device render "If lost…" info onto the lock screen didn't quite make it through to the new era.

If you don't want to spend any money on this and you do want to fiddle around, take a picture, and Photoshop in the contact information. Then set that image to the lock screen background.

Hotels In Northern California - How And Why To Rid Sugar From Your Diet

Ask most people how they feel about grocery shopping, and they may talk about the supermarket they'll never set foot into, where it smells bad and the produce looks pitiful, or the sunny one with nice cuts of meat and good prices on children's cereal. But to Robert Lustig, a professor of clinical pediatrics at the University of California, San Francisco School of Medicine, the supermarket is something else entirely. It's ground zero in the fight for your life, where decisions between plain or flavored Greek yogurt, oranges or orange juice, and red kidney beans or Bush's Grillin' Beans mean the difference between sickness and health.

The last 30 years have seen an onslaught of sugar and dwindling of fiber in the food environment, a deadly combination for consumers who have been duped by the food industry, Lustig argues. He sounded this battle cry in his 2009 lecture, "Sugar: The Bitter Truth," which became a viral hit with nearly 4 million views on YouTube, and in his 2012 book, "Fat Chance: Beating the Odds Against Sugar, Processed Food, Obesity and Disease."

Now, he's putting his message in more practical terms, offering consumers a handbook for the supermarket with "Sugar Has 56 Names: A Shopper's Guide." An e-book that's meant to travel with shoppers on their smartphones or tablets, the guide, released this month, provides consumers with a new nutrition label for hundreds of processed foods that puts the spotlight on where it should be, he argues: sugar. From soy milk to sausage, and Sara Lee to supermarket brands, the data delineates the quality and quantity of sugar in products. Why the distinction? Because, as the book's title indicates, sugar goes by varied names - from fructose to fruit juice, and these derivatives differ greatly in how they're processed by the body.

"By paying attention to the sugar portion of the label people can do better in terms of making their own decisions," Lustig says. The current nutrition label falls far short of that, he says, noting that the label lacks a percent daily value for sugar, which makes it difficult for people to calculate how much is too much.

Meanwhile, added sugar has crept into the food supply in everything from bread to barbecue sauce, and often the ingredients are cloaked in curious names and orders. For example, products list ingredients according to quantity, but a product might include various forms of sugar as its fifth through ninth ingredients, which, when added together, render sugar worthy of the first listing. But by reading a nutrition label, you can't distinguish between a food's inherent and added sugar, the behemoth between you and good health.

At stake, Lustig argues, is less the issue of obesity than the risk of metabolic diseases, which includes diabetes, heart disease, fatty liver disease, cancer and dementia. And sugar, he says, is a big part of the problem.

More details about the interaction of food substances on our physiology are provided in the book - he also has a low-sugar, high-fiber cookbook slated for release next year - but he leaves readers with some overarching directives, like these six tips: don't go to the supermarket hungry; shop along the perimeter of the supermarket where fresh, whole foods abound; if it comes with a logo you've heard of, it's been processed; avoid anything "partially hydrogenated" ("it will outlive you," he writes); just because it says "whole grain" doesn't mean it is, but if it doesn't say whole grain it isn't; if sugar is listed among the first three ingredients, it's dessert.

What else? Start your supper with a salad free of sugary dressing to fill up on fiber-rich food. Skip the cereal and granola bars and make a fast, healthy breakfast by scrambling eggs or frying some bacon the night before. Let your kids pack their (dessert-free) lunch with items they choose so they're more likely to eat it.

For his part, there's "no such thing as a sugared beverage" in his home. "We have milk, we have water and occasionally we have some alcoholic drinks when we have friends over," he says. "There is no reason to drink your calories." To ensure sufficient fiber, the Lustigs have salad with every meal, which typically consists of a protein and green vegetables and whole-grain bread instead of white rice, pasta and potatoes. For dessert, it's whole fruit, except for weekends, when they treat their daughters, ages 8 and 14, to something "a little more elaborate," he says.

"We have to get back to dessert being once a week, not once a meal," Lustig says. As he writes, "Sugar is reward. Sugar is fun, but if every meal is fun, then no meal is fun. And I promise, you won't be having fun taking your insulin shots while you're on dialysis."

To change the food culture, and the food supply, he encourages consumers to vote with their mouths and wallets. "We, as a society, have to reduce availability, and we cannot do that right now without the food industry helping us do it," he says. "If you won't buy it, they won't sell it."

Vacations In Santa Clarita - Airplane Wi-Fi Gets Up To Speed

The race for fast Internet at 30,000 feet is accelerating as airlines roll out new technologies and speedier connections—offering more productivity for business travelers but also encroaching on a rare refuge from the wired world.

Gogo Inc., GOGO +10.78% the largest provider of inflight Internet in the U.S., on Wednesday plans to unveil a system that uses a combination of satellites and cellular towers, connecting airplanes to the Web at speeds six times as fast as its current best option.

Virgin America Inc. will launch Gogo's new inflight Wi-Fi service in the second half of 2014 and says it expects to eventually upgrade its 53 aircraft with the product.

That comes after JetBlue Airways Corp. JBLU -2.04% received government approval last week to install a new high-capacity satellite link on many of its aircraft, an inflight Wi-Fi solution that can support streaming video to fliers' devices from Netflix Inc. NFLX -1.52% and Hulu, among others. 

JetBlue, which has lacked inflight Internet, plans to launch the service on some aircraft this year and equip its entire fleet of 180 aircraft by the end of 2015.

Gogo sets the prices for its onboard Wi-Fi, with options including $14 one-day passes and $50 monthly passes.

JetBlue said it is reviewing pricing for the service, but that basic Internet use initially will be free, while the airline will charge fliers for streaming content, which uses more bandwidth. Other airlines that provide Wi-Fi currently block access to streaming services like Netflix, to avoid cannibalizing their own fee-based inflight entertainment.

The new technologies could mean Internet speeds in the air that are at least as fast as the average Internet speeds for Americans on the ground—something that could help break down flier resistance to paying and make the service profitable. 

Almost nine of 10 U.S. fliers said they think every flight should offer Wi-Fi, according to a survey of 2,000 people released last week by Honeywell International Inc., which makes equipment for providing in-flight Internet. Yet Gogo said about 6% of potential customers currently purchase its Internet on flights.

Tim Farrar, a Menlo Park, Ca., satellite-industry consultant, said the same lower-than-expected percentage has generally held steady across the industry, "there's no indication of any dramatic shift" on the horizon and the trend could impede the swift growth that Gogo and rival services foresee. 

Some blame pokey speeds for that gap between desire and purchase. Fliers must share bandwidth, meaning that speeds slow when more passengers log on. David Cush, Virgin America's CEO, said that on average flights, about a fifth of its fliers pay for Wi-Fi, but that "it starts to top out at 30 to 35 users very simply because response time starts to degrade."

Gogo says its new service will offer speeds of 60 megabits per second to each airplane, compared with 3 mbps on its original Wi-Fi connection, which 1,700 aircraft still use, and 10 mbps on an updated product launched last year, which about 300 aircraft have. Panasonic Avionics Corp., which provides Wi-Fi to about 2,000 aircraft internationally, says its speeds now average 5 mbps to 10 mbps.

The average Internet connection on the ground in the U.S. is 8.6 mbps, according to Akamai Technologies Inc., a network operator.

JetBlue is connecting its aircraft via ViaSat Inc.'s VSAT +1.21% satellites, the first time a commercial airline will use the higher-capacity Ka-band satellite spectrum, which some in the industry see as the future of inflight Internet. Gogo intends to use a different constellation.

JetBlue said its new service would provide speeds of 12 mbps to each flier's device—not just the airplane, like on other providers. That model means "almost everyone on the airplane can enjoy that, not just one or two," said Don Buchman, ViaSat's director of mobile broadband.

Consultants said that JetBlue may be able to deliver high speeds to each device if several dozen fliers are just surfing the Web, but if users gravitate toward more bandwidth-intensive applications, JetBlue may find it hard to meet expectations.

Flights have been one of the few places that require people to unplug for a few hours. But since 2008, when AMR Corp.'s American Airlines flew the first Gogo-equipped commercial aircraft, the U.S. airline industry has rapidly expanded inflight Wi-Fi, connecting nearly 2,500 aircraft over the period.

Today, nearly 60% of commercial passenger aircraft in the U.S. are connected, not counting commuter jets, according to a Wall Street Journal survey of the nation's 12 biggest airlines. That compares with about 35% two years ago. By the end of 2015, the airlines plan to have more than 85% of their mainline aircraft connected, including virtually all of the larger jets flown by the nation's biggest carriers.

"It's bittersweet," said Jason Cupp, an independent management consultant from Kansas City, Mo., who took about 150 flights last year. "On one hand, it's good because I get a lot of work done. On the other, [a plane] is the only space in literally my entire life where I'm not on the Internet."

Matt Nevans, who travels more than 200,000 miles a year helping local governments set up email systems, said he is a loyal flier of United Continental Holdings Inc. But in recent years, as United was slow in adding inflight Wi-Fi, "I chose other airlines because I knew I needed to be online" during the flight. 

United expects to add Wi-Fi to 200 of its 700 mainline aircraft by the end of the year, from 90 now, and to be fully equipped by the end of 2015. 

"It's been a long time coming," Mr. Nevans said. 

Various foreign carriers have tried to focus on business travelers by maximizing connectivity on long-haul and intercontinental runs. But in some cases the revenue hasn't been as hefty as envisioned, according to industry consultants, partly because many of those trips are overnight flights. There also are signs that short-haul flights may not be conducive to streaming video. Southwest Airlines Co. which specializes in such flights, originally agreed to have Row44 Inc., is a unit of Global Eagle Acquisition Corp., provide such content for a fee. But at least temporarily, the connectivity is now being provided free of charge as long as users watch a brief advertisement for sponsor satellite-broadcaster Dish Network Inc.

Gogo posted a loss of $70.5 million in the first half of this year. According to Mr. Farrar, Wall Street analysts expect Gogo's revenue to climb to about $500 million over the next two or three years from an estimated $300 million in 2013. But plans to enhance Gogo's hybrid network will cost hundreds of millions of dollars over the same period, according to industry consultants and analysts.

Jimmy Schaeffler, who runs satellite consultancy the Carmel Group, said hybrid satellite and land-based systems "still may have to contend with quality issues stemming from clouds, weather systems and other factors."
