NASA’s Orion capsule: Here’s how it will work????

The first test flight of NASA’s Orion capsule: Here’s how it will work

The Orion capsule and service module, attached to Delta IV upper stage

Early tomorrow morning, Thursday December 4, NASA is scheduled to perform the first test flight of the new Orion spacecraft. The entirety of NASA’s human space exploration plan hinges on Orion — if the series of test launches go off without a hitch, Orion, eventually powered by the massive new Space Launch System rocket, will land humans on an asteroid in 2025, and then Mars around 2030. But first, let’s discuss the first test launch taking place tomorrow morning.

Exploration Flight Test 1

At around 7:05am Eastern time, December 4, an unmanned Orion capsule — perched atop a Delta IV Heavy rocket — will lift off from Cape Canaveral. The plan is to get to an altitude of around 3,600 miles above Earth — about 15 times the altitude of the International Space Station — do a couple of orbits, and then land in the Pacific Ocean about four-and-a-half hours later. The test flight is designed to imitate all of the the same processes/phases that would occur during a real, crewed flight, so that NASA can make sure everything is working as planned before we send humans back into deep space — something we haven’t done since the Apollo missions 40 years ago.
Let’s look at each of the test flight’s stages in detail. The cute illustrations, incidentally, are directly from NASA.
Orion EFT-1 mission plan

Pre-launch

The action for EFT-1 begins 8 hours prior to launch — or “T minus 8 hours” in aerospace lingo — with the support gantry being pulled away from the rocket/capsule. Over the next few hours, a series of go/no-go tests are performed for each of the rocket’s major systems; if the weather is bad, or a seal is faulty, or any of the various systems aren’t operating quite as expected, the launch might be called off. Generally, NASA and the United Launch Alliance (Lockheed/Boeing, which operates the Delta IV Heavy rocket) will try its best to fix any issues that arise, to make sure they hit the launch window. At T-0:08, 8 minutes until launch, the final go/no-go poll is carried out, Orion switches to internal power, and the launch will go ahead as planned.
Orion launch

Launch

For this first test flight, Orion is being launched upon a Delta IV Heavy rocket — currently the world’s most powerful/highest capacity rocket. This will be the first and only time that Orion uses a Delta rocket; the next test flight, scheduled for 2017, will use NASA’s new super-heavy-lifting Space Launch System. A Delta IV is being used in this case because it allows NASA to gather important data that will inform the construction of the second Orion capsule, which will travel all the way around the Moon.
Five and a half minutes after launch, at an altitude of around 200 miles, both the Delta IV’s main and booster engines will have expended all their fuel. A few seconds later, the whole bottom end of the rocket (the first stage) detaches. The second stage engine, which takes Orion into a higher orbit, ignites.
Orion exposure

Exposure

Now that Orion is in space, the upper stage’s protective fairings peel away. The launch abort system, which would protect the cargo/astronauts in case of a bad launch, also jettisons. This is where we find out if Orion was appropriately designed and engineered to endure the rigors of space. (I’m sure it will be.)
The image at the top of the story shows you what the spacecraft + rocket will look like at this point. The bit at the end is the command module (where the humans would be located); the bit behind that is the service module; and the rocket at the end is the Delta IV second stage.
Orion reignition

Re-ignition

After two hours, and one low-altitude orbit of Earth, the second-stage rocket will fire again, pushing Orion up to an altitude of 3,600 miles (5,800 km). Orion will travel through the high-radiation Van Allen Belts as steadily climbs above Earth. At around three hours after liftoff, Orion will hit its peak altitude… and then slowly start its descent back to Earth.
Orion separation

Separation

At around 3 hours 20 minutes, after a few little maneuvers, the Orion capsule — the tiny little Apollo-like capsule at the top of the whole rocket — will detach from the service module and second stage of the Delta rocket. At this point, Orion is on a trajectory to hit the Earth’s atmosphere; the service module and rocket motor are just unwanted mass.
Orion reorientation

Orientation

Around four hours after liftoff, Orion’s small maneuvering thrusters will reorient the capsule so that it’s at the right angle for reentry into the Earth’s atmosphere. On its way back to Earth, Orion will re-enter the Van Allen Belts, for another dose of exciting radiation.
The Apollo capsule during atmospheric reentry
The 1960s-era Apollo capsule during atmospheric reentry. Yes, this isn’t the Orion capsule; I just thought it looked too cool to not use. (Plus, Orion is heavily based on Apollo.)

Reentry

Finally, at around 4 hours 15 minutes, probably the most important and exciting bit of EFT-1: Reentry into Earth’s atmosphere, and seeing whether Orion’s heat shielding works as expected. The reason such a high altitude was chosen for a first test was so that the angle and speed — and thus the stresses during atmospheric reenetry — were comparable to a return mission from the Moon. Orion will hit the Earth’s atmosphere at around 20,000 miles per hour.
Orion parachutesOrion splashdown

Landing

At 4 hours 20 minutes, Orion is through most of the atmosphere and has slowed from 20,000 mph to just 300 mph. A series of parachutes deploys — two small parachutes to begin the deceleration, then three drogue parachutes that pull out three massive main parachutes. Bear in mind that the Orion capsule weighs about 9 tonnes. A few minutes later, the main parachutes have slowed Orion down to around 20 mph — slow enough for a safe splashdown about 600 miles off the coast of California in the Pacific Ocean.
If everything goes to plan, the splashdown will be exactly 4 hours and 23 minutes after launch — or around 8:30am Pacific time.
So, there you have it: The exact mission plan for Exploration Flight Test 1. We’ll be covering the launch live tomorrow, of course, along with a live video feed — so stay tuned!

E-paper smartwatch by Sony

Sony's crowdfunded surprise: E-paper smartwatch

Sony's crowdfunded surprise: E-paper smartwatch

NEW DELHI: Sony is developing a new smartwatch that features an electronic paper or e-paper.

According to a report by The Wall Street Journal, the company's "Fashion Entertainments" project is focusing on the development of e-paper fashion gadgets.

Sony has even developed a prototype of a watch called Fes Watch, which sports an e-paper wristband that can change its appearance with the user's gesture. It offers 24 design patterns which can be selected by the user. The watch is more of a fashion accessory and doesn't boast of many smart features.

Interestingly, Sony had put the Fes Watch on a Japanese crowdfunding website in September, to gauge user interest without revealing the brand name. According to the report, the watch its initial goal of raising 2 million yen ($17,000) in three weeks and attracted 3.5 million yen from over 150 supporters.

While Sony has not commented on the release timeline, the crowdfunding website mentions a post-May 2015 release for contributors.

Sony is also developing e-ink-based bow ties, hat accessories and paper holders.

Sony offers smartwatches under its SmartWatch range with the SmartWatch 3 being its latest Android Wear-powered watch. It also offers lifestyle and fitness bands.

Firefox and Google are breaking up.


Firefox dumps Google for Yahoo as default search engine

 Firefox and Google are breaking up.

Maybe it was that Google (GOOGLE, Tech30) has a competing browser, making them strange bedfellows. Or after ten years of partnership, it was time for change. Or maybe Yahoo (YAHOO, Tech30) just offered to pay more.
Yahoo is replacing Google as the default search engine for Mozilla's Firefox browser, the companies announced late Wednesday. With 10% of the market, it is the Internet's third most popular search engine, behind Google's Chrome and Microsoft's (MSFT, Tech30) Bing (which powers Yahoo searches).
The change is significant for Firefox users, who perform some 100 million searches in the browser every year, according to Mozilla.
It is significant for Mozilla, a non-profit that is heavily reliant on revenue from search companies. Google's three-year contract with Firefox, which will come to an end in December, had reportedly been worth $1 billion. Yahoo and Mozilla did not disclose terms of their five-year search deal.
Mozilla's most recent publicly available financial report (from 2012) notes a single search company -- apparently Google -- provided between two-thirds and three-quarters of its $311 million revenue stream. (The organization also brings in much smaller chunks of change through avenues like user contributions.)
The deal is significant for Yahoo, which under CEO Marissa Mayer has increased its focus on search. In the announcement, she called it "a key growth area for us." The Mozilla partnership will be the launchpad for redesigned Yahoo search pages.
The announcement also means Yahoo will agree to Firefox's Do Not Track feature, which allows users to request sites not collect their personal information. It's a request, not an order, and one that Yahoo said in April it would not honor.

Facebook is unbanned in China for three days.

China lifts ban on Facebook for select few

china internet

Blink and you'll miss it: Facebook is unbanned in China for three days.

China is hosting an Internet conference this week in Wuzhen, a sleepy town located about halfway between Shanghai and Hangzhou, the headquarters of e-commerce juggernaut Alibaba (BABA, Tech30).
Wuzhen is sometimes called a "Venice of the East" for its network of canals, but during the conference the city carries another distinction: It's the only place in China where users can freely access Facebook (FB, Tech30), Twitter (TWTR, Tech30) and Instagram.
The Internet is closely controlled in China. Most Western social media platforms are banned, and Beijing has invested heavily in a firewall that restricts access to thousands of websites it deems controversial.
But Chinese officials have reportedly punched a hole in the "Great Firewall" for the inaugural World Internet Conference, allowing more than 1,000 attendees to access parts of the Internet that are off limits to 1.3 billion Chinese.
Banned! 7 things you won't find in China
The concession underlines the dilemma facing non-Chinese tech firms as they try to reconcile the country's enormous potential with its heavy-handed approach to censorship and market access.
Executives from tech firms including Facebook (FB, Tech30), Cisco (CSCO, Tech30) and Qualcomm (QCOM, Tech30), for example, are at the conference. But Facebook is banned inside China, Qualcomm was recently investigated as part of an antitrust probe, and Cisco has been caught in the fallout of the Snowden spy scandal.
When questioned by reporters about about their companies' position in China, the executives were not forthcoming.

Made by China in America

At the conference, Chinese officials presented a vision for the Internet that Western users would find unfamiliar. They emphasized the rule of law, and urged website operators to adhere to regulations.
Ren Xianliang, a top official at the Cyberspace Administration of China, stressed that citizens should use the Internet to "spread positive energy."

The conference drew the ire of Amnesty International, which said China's Internet model is one of "extreme control and suppression."
"China appears eager to promote its own domestic Internet rules as a model for global regulation," said William Nee, a researcher at the human rights group."This should send a chill down the spine of anyone that values online freedom."
Yet China is unlikely to change course. For Beijing, it's a matter of national security, and that means large swaths of the Internet -- especially social media platforms -- will remain out of reach for most Chinese.
"I have never used such websites, so I have no information about their accessibility in China, but I assume some may not be accessible," China's top Internet regulator Lu Wei said in advance of the conference. "I can choose who will be a guest in my home."

Android Lollipop vs Android KitKat:

Android Lollipop vs Android KitKat: What's the difference?


Android Lollipop vs Android KitKat: What's the difference?

>>There was plenty of debate over what the new version of Android would be called, with "Lemon Meringue" and even the controversial "Licorice" said to have been in the running at various points.

Thankfully the lovable "Lollipop" won out, as Google revealed when it unveiled the new Android update, but the name is hardly all that's been improved since the last version.

Here's exactly how Android 5.0 stacks up to Android KitKat.

Material world

Material world
Android Lollipop is the biggest change to Android in some time, finally bumping Google's OS up a full integer to version 5.0.

It's packed with changes, but the most obvious improvements are visual.

Google's been working on getting its new "Material Design" aesthetic out in the world for months, and Lollipop is its culmination. One of Android's biggest failings up to date — including with KitKat — has been that its design language never felt unified, and with Material Design Google hopes to fix that.

Material Design reflects this with clean, bold lines and colors that transform and alter with fun animations. At its best it lets you sense the depth behind the interface, even when it's at rest and appears flat.

This extends from app icons, fonts and interfaces to simple elements like the new navigation buttons and notification bar icons, and once you get past the changes you'll likely agree that most things look better now.

The changes to Android's interface with Lollipop aren't all visual, either — voice commands with "OK Google" are more prominent now as well, and can even be used when the screen is locked and off on some devices, and there are massive improvements to notifications.

Notifications

Notifications
Notifications have been significantly overhauled in Android Lollipop.

The OS's lockscreen is no longer a static barrier you have to get through before you can reach the meat of your phone's functionality, but instead now has many elements of KitKat's notification panel, plus more interactivity.

In Lollipop you can see what notifications you've received and what's going on with your apps and contacts as soon as you pick it up, before you even unlock your device — and you can even respond to messages from the lockscreen.

The way you see notifications is changing as well — now rich, descriptive, and interactive notifiers will pop up on top of what you're doing without interrupting, so you can reject a call or read a message without quitting that game or whatever. Some of this functionality was present in KitKat, but it was half-baked and inconsistent.

Android Lollipop is also getting a "do not disturb" mode a la iOS, which Android KitKat and previous versions sorely lacked. You can use it to silence your ever-buzzing phone during specific hours or, more importantly, to only let notifications from specific sources come through.

Lollipop's quick settings bar also has new options that KitKat desperately needed, like easy buttons for flashlight, hotspots, and screencasting. Wi-Fi, Bluetooth and location options have been expanded here as well.

Connectivity and APIs

Connectivity and APIs
With Android Lollipop Google is making connectivity a big focus not just between different handsets, but among different classes of device as well. For example Android TV is now built right into Android Lollipop, helping you easily navigate big screens with smartwatch voice commands, phone gestures, and more.

That's just scratching the surface, but it means your Android experience will be consistent across smartphones, tablets, TVs, smartwatches, and more.

Google also wants Lollipop's apps to communicate with one another more than KitKat's do. Examples are simple, like tapping links in Chrome and having them open in specific apps instead of taking you to mobile websites. The OS already does it sometimes, but Google wants it to be more consistent.

This depends quite a bit on app developers taking advantage of Lollipop's 5,000 new APIs. These will make the new Android OS more versatile over time, though their presence might not be noticeable for end users at first.

Google says Lollipop is also better at connecting with Bluetooth and Wi-Fi. For example Lollipop devices won't connect to a Wi-Fi network unless they can verify there's an actual connection there — so unlike with KitKat, you won't be stumped wondering why you suddenly have no data because your gadget decided to connect to a turd of a network.

Safe and sound

Safe and sound
Android Lollipop has some new security features as well, like the ability to set geographical "safe zones" where your device won't require a PIN to unlock.

You can do the same with specific Bluetooth devices, like Android Wear smartwatches, which your phone or tablet will sense automatically and turn off its security barriers.

And despite all the changes to notifications that let you see and interact with them without unlocking your phone, Android 5.0 also has new settings that let you hide sensitive information anywhere it might appear.

Lollipop also has better protection against vulnerabilities and malware thanks to SELinux enforcing for all applications, and encryption is turned on by default on all Lollipop devices.

And multiple user profiles on a single device, including temporary guest profiles, makes it easier to share your phone with others while still maintaining control over your own stuff.

Performance

Performance
Google has reportedly also put a lot of work into making Android Lollipop run better under the hood.

KitKat's optional runtime ART is now the standard for Android Lollipop, and Google says it will help make Lollipop run faster, more efficiently and with less hiccups.

That won't harm existing Android apps' compatibility, but it has let Google future-proof Android further against the inevitable onslaught of 64-bit smartphones coming in the near future.

These phones will have more RAM than existing phones with KitKat and other operating systems are capable of packing, which is a huge benefit that only future generations of Lollipop handsets will be able to take advantage of.

For now, though, Google says Android 5.0 is way more power-efficient over its predecessors, with the same phones getting significantly more battery juice out of Lollipop than they did with KitKat.

Multitasking has also been updated with the ability to have multiple cards for the same apps open at a time, letting you have more than one document or website next to one another, for example. It's also easier to switch keyboards now too, and Android Lollipop even supports RAW images.
