BEIJING — China’s burgeoning space program achieved a lunar milestone on Thursday: landing a probe on the mysterious and misnamed “dark” side of the moon.
Exploring the cosmos from that far side of the moon, which people can’t see from Earth, could eventually help scientists learn more about the early days of the solar system and maybe even the birth of the universe’s first stars.
Three nations — the United States, the former Soviet Union and more recently China — all have sent spacecraft to the side of the moon that faces Earth, but this landing is the first on the far side. That side has been observed many times from lunar orbit, but never up close.
The China National Space Administration said the 10:26 a.m. touchdown of the Chang’e 4 craft has “opened up a new chapter in human lunar exploration.”
A photo taken at 11:40 a.m. and sent back by Chang’e 4 shows a small crater and a barren surface that appears to be illuminated by a light from the lunar explorer. Its name comes from that of a Chinese goddess who, according to legend, has lived on the moon for millennia.
One challenge of sending a probe to the moon’s far side is communicating with it from Earth, so China launched a relay satellite in May to enable Chang’e 4 to send back information.
The mission highlights China’s growing ambitions to rival the U.S., Russia and Europe in space, and more broadly, to cement its position as a regional and global power.
“The space dream is part of the dream to make China stronger,” President Xi Jinping said after becoming the country’s leader in 2013.
Chinese media and officials hailed the Dec. 8 launch of Chang’e 4 as one of the nation’s major achievements in 2018.
The public was kept in suspense about the landing itself for more than an hour after it occurred, with state broadcaster CCTV announcing it at the top of the noon news. By that time, speculation already had begun spreading on social media in China and overseas.
“On the whole, China’s space technology still lags behind the West, but with the landing on the far side of the moon, we have raced to the front,” said Hou Xiyun, a professor at Nanjing University’s school of astronomy and space science.
He added that China has Mars, Jupiter and asteroids in its sights: “There’s no doubt that our nation will go farther and farther.”
The landing was “a big deal” because it used an engineering technique of the spacecraft itself choosing a safe place to touch down in treacherous terrain, something called autonomous hazard avoidance, said Purdue University lunar and planetary scientist Jay Melosh.
He recalled mentioning the idea of such a technique for an unfunded NASA lunar mission about eight years ago, only to be told it wasn’t doable at the time.
“The moon is more challenging to land on than Mars,” Melosh said. “On Mars, you can pick out smooth areas.”
In 2013, the predecessor spacecraft Chang’e 3 made the first moon landing since the former Soviet Union’s Luna 24 in 1976. The United States is the only country to successfully send astronauts to the moon — 2019 will mark the 50th anniversary of the Apollo 11 lunar landing — although China is considering a crewed mission too.
For now, it plans to send a Chang’e 5 probe to the moon next year and have it return to Earth with samples — also not done since the Soviet mission in 1976.
The moon’s far side is sometimes called the “dark side” in popular culture because it is always unseen from Earth and is relatively unknown, not because it lacks sunlight.
Chang’e 4, a combined lander and rover, will make astronomical observations and probe the composition of the soil.
The spacecraft landed in the South Pole-Aitken basin, the oldest known impact zone. Scientists want to know how old — somewhere between 3.9 billion and 4.4 billion years old — to better understand a period in the solar system’s history called the late heavy bombardment. That’s when space rocks were careening off each other and crashing into moons and planets, including Earth. Knowing the age and chemical composition of this crash zone would help understand Earth’s ancient history better, said Purdue’s Melosh.

2.      All necessary means': Xi Jinping reserves right to use force against Taiwan
Chinese leader calls for reunification and says independence would be a ‘disaster’
The Guardian    2 Jan 2019


Taiwan’s unification with China is inevitable, Xi Jinping has said as he warned that Beijing reserved the right to use military force to bring it into the fold.
Speaking in Beijing’s Great Hall of the People on the 40th anniversary of a key cross-strait policy statement, the Chinese president described reunification with Taiwan as unavoidable.
“Reunification is the historical trend and it is the right path,” Xi said. “Taiwan’s independence is a reversal of history and a dead-end road.”
All people in Taiwan must “clearly recognise that Taiwan’s independence would only bring profound disaster to Taiwan”, he said.

Taiwan, which has never been under the Chinese Communist party’s control, is China’s most sensitive issue and is claimed by Beijing as its sacred territory.
Xi has stepped up pressure on the democratically governed island since Tsai Ing-wen, of the pro-independence Democratic Progressive party, became president in 2016.
“We make no promise to renounce the use of force and reserve the option of taking all necessary means,” Xi said, adding that the issue was an internal one and that China would permit “no external interference”.
“We are willing to create broad space for peaceful reunification, but will leave no room for any form of separatist activities,” he said.
Xi’s speech was conciliatory in parts, echoing China’s 1979 “message to compatriots in Taiwan”, which eventually led to a thaw in relations between the two sides.
Chinese nationalists fled to Taiwan in 1949 and set up a rival government. In the 1990s Taiwan democratised, and it is often held up as an example of democratic reforms.
Xi promised that Beijing would respect Taiwanese citizens’ private assets, their beliefs, freedom to practise religion and other “legitimate rights”, an arrangement similar to the “one country, two systems” model under which Hong Kong is governed.
“After peaceful reunification, Taiwan will have lasting peace and the people will enjoy good and prosperous lives. With the great motherland’s support, Taiwan compatriots’ welfare will be even better, their development space will be even greater,” Xi said.
Xi said China was willing to talk with any party in Taiwan to push the political process – stalled by China since Tsai took office – as long as they accepted the principle of “one China”. That policy maintains that Taiwan is part of China.
In response to Xi’s speech on Wednesday, Tsai rejected the possibility of such an arrangement. “I call on China to bravely take step towards democracy so they can truly understand the people of Taiwan,” she posted on Twitter.
A day before the address, Tsai said the two countries “must handle our differences peacefully and as equals”.
“I am calling on China that it must face the reality of the existence of the Republic of China (Taiwan),” she said, using Taiwan’s formal name. Beijing “must respect the commitment of the 23 million people of Taiwan to freedom and democracy”, she added.

Beijing has refused official communication with Tsai’s administration because of her refusal to agree with the One China policy.

3.      Samsung in 2019: Get ready for foldable phones, 5G and more
Last year's hardware was ho-hum, but Samsung's got plenty brewing to wow us this year. And it all kicks in next week at CES.
CNET    JANUARY 4, 2019

Samsung's phones last year weren't quite what you'd call earthshaking.
Its Galaxy S9S9 Plus and Note 9 didn't have many noticeable changes from 2017's Galaxy S8, S8 Plus and Note 8. Sure, they had faster processors and other souped-up components. But they kept the same design, something that reportedly has hurt demand for the smartphones.
After all, why buy the new, pricier devices when the previous year's models are nearly as good? That's been the problem for Samsung and other handset makers, who tend to save major updates for every other year, if then. It's one reason Apple and Samsung handset sales are slowing and the global smartphone market is said to be in recession. We're all holding onto our phones longer than before, and it's tougher for smartphone makers to produce big, flashy innovations.

For Samsung in 2019, that's going to change. 
New components from its own operations, Qualcomm and others will enable some of the biggest innovations in phones we'll have seen in years. That includes ultrafast 5G connectivity and truly flexible, foldable displays. No longer just a black, rectangular slab of glass, smartphones this year and next could be much different from anything we've used before. We may actually get excited about phones again.
"2019 is really going to be a breakout year for Samsung," Technalysis Research analyst Bob O'Donnell said. "It puts them in a very unique position as really being seen as the technology leader."
Samsung's big year starts next week at CES in Las Vegas. 
The company isn't expected to have mobile news at the show but instead will focus on its TVs and home appliances. It's the following month that will likely mark the debut of Samsung's next flagship phone, the Galaxy S10. And coming later will be its foldable phone, dubbed the Galaxy X or Galaxy F.
Samsung declined to comment.

Galaxy S10
Next year's flagship phone from Samsung may not actually be its flashiest device (that's probably going to be the foldable gadget), but it's expected to offer plenty of big changes. That's important, since the Galaxy S10 is the phone most Android users ready to upgrade will consider.
First up for the Galaxy S10 is 5G, the new flavor of mobile tech that will significantly boost the speed, coverage and responsiveness of wireless networks. It promises to make phones upload and download data 10 to 100 times faster than with today's typical 4G LTE network. Movies could be downloaded in seconds, rather than minutes. 5G networks will roll out in the US and around the world in the coming months, starting with smaller cities before making their way to major metropolises and even rural areas.

Samsung has said it will introduce a 5G phone for Verizon, AT&T and other wireless providers in the first half of 2019. It's believed one version of the Galaxy S10 will come with 5G connectivity, though it's likely Samsung won't offer 5G on all its phones. 5G components are expensive and the service isn't yet in all markets. That means the 5G variant will likely be pricey.
Another likely major feature in the Galaxy S10 is an in-screen fingerprint reader.  Samsung is expected to use the Qualcomm Snapdragon 855 processor, the first chip that supports Qualcomm's 3D Sonic Sensor, an ultrasonic fingerprint readerthat's embedded right into the display itself.
That means Samsung fingerprint readers could return to the front screen, instead of next to a phone's camera lenses on the back -- something consumers complained about. With that 3D Sonic Sensor, Samsung can still offer a display that stretches across the entire front. It's expected to be much more secure than Samsung's Face Unlock technology.
Those two features alone are likely enough to woo many smartphone buyers who've been waiting on the sidelines.
