China’s new Long March-8 rocket makes first flight

China’s new carrier rocket, the Long March-8, made its maiden flight on Tuesday, the country’s space agency said, the first phase of a strategy to deploy launch vehicles that can be reused.

The Long March-8 series is part of China’s endeavours to develop reusable rockets,     1     lowering mission costs and paving the way towards     2     launch services.

The programme has drawn parallels to private US rocket firm SpaceX’s Falcon     3    , although China said in 2018 its reusable carrier vehicle would use different technologies.

The new medium-lift carrier rocket sent five satellites into planned     4    , blasting off from the Wenchang launch site on the southern Hainan island at 12:37 pm Beijing time (0437 GMT) on Tuesday.

It    5     50.3 metres and has a take-off mass of 356 tonnes, and the China National Space Administration (CNSA) said it is of "great significance for accelerating the upgrading of launch vehicles".

The rocket’s design was based on technologies developed for previous Long March editions, Xinhua reported Tuesday.

It is also expected to lay the foundation for development of large and heavy rockets, shortening development periods and     6     costs, said Song Zhengyu, the chief designer of the Long March-8.

The five experimental satellites launched by the new rocket will     7     experiments in space science, remote sensing and communication technologies, said Xinhua.

Beijing has invested heavily in its space     8     as a sign of its technological prowess and scientific endeavour.

A(n)    9     Chinese spacecraft returned to earth last week with rocks and soil from the moon—the first     10     samples collected in four decades.

The Long March 8 rocket will eventually help China replace its fleet of medium-lift launch vehicles, providing launch services for low Earth orbit satellite constellations and payloads bound for higher altitudes, such as geosynchronous orbit, CASC said.

Google gives $1M grant to Press Association to develop robot journalists

New consumers of the future could be reading stories pieced together by advanced data-analyzing robots rather than human journalists, if Google has its way.

On Thursday, the Press Association, the U.K.’s national news agency, announced that it received €706,000 from the tech giant for its Reporters and Data an Robots (RADAR)     1    .

A collaboration between the Press Association and data-driven news start-up Urbs Media, RADAR aims to set up an artificial intelligene-fueled, news service that will generate tens of thousands of news stories a month using publicly     2     data.

Everyone from big-name news organizations to hyper-local outlets and bloggers could     3     from the program. Press Association editor-in-chief Peter Clifton claimed, “this is a hugely exciting development, and we believe our     4     with Urbs Media can be a genuine game-changer for media outlets across the U. K. and Ireland.”

According to the Press Association, RADAR won’t     5     mark the end of the flesh-and-blood journalists, but will rather enable the AI to produce a volume of stories that would be impossible to match manually.

The envisioned work-flow would begin with human journalists identifying open data sets and “creating detailed story templates across a(n)     6     of topics including crime, health and employment.” The robotic reporter would then take over and scan the data, use language generation software to craft together story text and automatically locate relevant photos and video. Press Association clients would then be able to use a special distribution platform to identify news stories of     7     to their audience.

Content automation isn’t a totally     8     concept in the news industry however. AP estimated that it can free up 20 per cent of journalists’ time, allowing them to focus on more complex, qualitative tasks.

Shockingly, not all journalists are sold on the AI infiltration. A study found that journalists from leading news organizations had several reservations when shown an automatically     9     sports story. “I would never, ever, ever have written a story like that,” one BBC journalist said, while a CNN reporter thought the story was repetitive and lacked variation.

Nevertheless, it looks like AI in journalism is here to stay. At a time when many media outlets are     10     commercial pressure, RADAR will provide the news ecosystem with a cost-effective way to provide insightful local stories.

You’ll Never Be Truly Alone

In the decades to come, a large number of home robots could make today’s appliances seem interesting. The market for consumer and office robots is expected to develop quickly in the next three years, according to a 2015 report by Business Insider Intelligence, being greater than $1.5 billion and far     1     the growth of robots in manufacturing.

We already have robots that clean the house, like the Roomba, but in the future we’ll also have robot arms that can     2     surfaces and bathe people, says Christopher Atkeson, a roboticist at Carnegie Mellon, whose lab has produced such machines. Eventually, robots will fold laundry and cook meals. And if they work well, you won’t even notice them. The key to effective robots is ”being     3    of predicting what people will do,“ says Julie Shah, the head of the Interactive Robotics Group at MIT. ”The idea is either     4     people or staying out of their way.“

That said, some people may want a robot that hangs around. In Japan, a friendly humanoid robot called Pepper that can    5    and respond to human emotion has proved enormously popular since it went on sale two years ago. Pepper might turn out to be the     6    roommate- helpful, kind, and always up for hanging out, but never in the way.

Perhaps the already     7    line between online and offline life will disappear, and human relationships with intelligent machines will represent a new extension of our social    8    . Your in-hour robot could serve as an avatar(化身)for friends and family,     9     from afar so that, with the help of robotic arms and legs, you could dance with or hug a loved one who is halfway around the planet. The real     10    of - or problem with - the house of the future, then, might be that you’ll never have to leave it. However, what the future house will be like still remains to be seen.

In ancient times, our ancestors relied on stars to guide them on a clear night. Today, we have navigational systems to help us find our way, with the latest being the Beidou Navigation Satellite System (BDS).

The BDS is entirely built by Chinese engineers. With the     1     of the last satellite from the Xichang Satellite Launch Center on June 23, the global network of 59 satellites has been completed. On July 31, Beidou started providing full-scale global services. It’s difficult to imagine the great     2     those satellites, orbiting (围绕……运转) the Earth, have on our daily lives.

When you unlock one of Hellobike’s bicycles, you are using the BDS. The popular bike-sharing company came out with two new bike models this year that are     3     with the positioning service. “The intelligent lock on each bike receives Beidou satellite     4     and sends positioning information to the data center, which will help collect big data on the bikes and estimate users’ riding     5     in advance according to the data,” Chu Yiqun, a manager of Hellobike told Xinhua News Agency. Users can also find shared bikes more accurately thanks to Beidou’s global positioning accuracy of 2.34 meters.

However, the BDS doesn’t just work one way. As the country’s largest space-based system and one of four global navigation networks, along with the United States’ GPS, Russia’s GLONASS and the European Union’s Galileo, Beidou     6     a unique two-way communication system, including its ability to receive messages sent by people from areas with poor communication signals. Obviously, this exclusive function isn’t designed for users to chat online. Instead, it plays a role when disasters occur and communications are blocked.

After the Wenchuan earthquake in 2008, all ground-based communication     7     were interrupted. Though the first generation of Beidou could only send 120 characters in a single message at that time, communication between     8     areas and rescue centers was successful. Now, Beidou’s messaging capacity has been increased to 1,200 Chinese characters in a single message. It is widely used in disaster     9    , automatic identification and information release.

As Sun Jiadong, former chief designer of the BDS said: “The application of Beidou is only     10     by imagination.”
