Mysteries of Ultima Thule unravelled by NASA’s New Horizons

Published

on

LOS ANGELES: New Horizons mission team of NASA yesterday (Monday 18th March)  unraveled mysteries of the Kuiper Belt object (KBO) nicknamed Ultima Thule, the most distant object ever explored by mankind.
New Horizons performed the farthest flyby in history at 12:33 a.m. EST (0533 GMT) on New Year’s Day, as it approached Ultima Thule within 2,200 miles (about 3,540 km) of the surface at a velocity of 31,500 miles (about 50,694 km) per hour. Analyzing the data New Horizons has been sending home since the flyby, mission scientists are learning more about the formation, geology, and composition of this ancient relic of solar system formation, said a NASA release.
Ultima Thule is the first unquestionably primordial contact binary ever explored, said the mission team. Approach pictures of Ultima Thule hinted at a strange, snowman-like shape for the binary, but further analysis of images taken near closest approach uncovered the object’s unusual shape. Ultima Thule consists of a large and flat lobe (nicknamed “Ultima”) connected to a smaller and rounder lobe (nicknamed “Thule”).
“We’ve never seen anything like this anywhere in the solar system,” said New Horizons Principal Investigator Alan Stern. “It is sending the planetary science community back to the drawing board to understand how planetesimals – the building blocks of the planets – form.” Scientists believe Ultima Thule’s two lobes once orbited each other, like many so-called binary worlds in the Kuiper Belt, until something brought them together in a “gentle” merger. The “neck” connecting Ultima and Thule is bent, and could indicate shearing as the lobes combined, said Kirby Runyon, a New Horizons science team member.
In terms of color and composition, Ultima Thule is very red – redder even than Pluto, which New Horizons flew past on the inner edge of the Kuiper Belt in 2015, and about the same color as many other so-called “cold classical” KBOs, said the team. New Horizons scientists have also seen evidence for methanol, water ice and organic molecules on the surface. Currently, the New Horizons spacecraft is 4.1 billion miles (6.6 billion kilometers) from Earth, operating normally and speeding deeper into the Kuiper Belt at nearly 33,000 miles (53,000 kilometers) per hour.

Samsung to inspect Galaxy Fold phones after reviewer complaints

Published

on

SEOUL: Samsung announced Thursday it will inspect units of its highly anticipated folding smartphone after some reviewers reported screen damage.

A handful of US-based reporters were given the flagship Galaxy Fold phones, priced at $1,980, ahead of the model’s official release next week, and they reported screen issues within days of using the devices.

“The screen on my Galaxy Fold review unit is completely broken and unusable just two days in,” Bloomberg’s Mark Gunman tweeted.

And Dieter Bohn of The Verge said: “Something happened to my Galaxy Fold screen and caused a bulge… It’s broken.”

Samsung spent nearly eight years developing the Galaxy Fold, which is part of the South Korean tech giant’s strategy to propel growth with groundbreaking gadgets.

“We will thoroughly inspect these units in person to determine the cause of the matter,” Samsung said in a statement after reports of the screen damage emerged.

The firm suggested some reviewers encountered screen failures because a section of the display was removed.

“The main display on the Galaxy Fold features a top protective layer, which is part of the display structure designed to protect the screen from unintended scratches,” it said.

“Removing the protective layer or adding adhesives to the main display may cause damage. We will ensure this information is clearly delivered to our customers.”

Some of the reviewers, including Bloomberg’s Gunman, had removed this layer.

CNBC’s Steve Kovach said he had not, but still faced major problems with the device.

Samsung is the world’s biggest smartphone maker, and earlier this month launched the 5G version of its top-end Galaxy S10 device.

But despite the recent announcements about its new high-end devices, Samsung has warned of a more than 60 percent plunge in first-quarter operating profit in the face of weakening markets.

The firm is also no stranger to device issues.

Its reputation suffered a major blow after a damaging worldwide recall of its Galaxy Note 7 devices over exploding batteries in 2016, which cost the firm billions of dollars and shattered its global brand image.
Samsung has said it will release the Galaxy Fold as scheduled on April 26.

Ericsson, Swisscom launch Europe’s first large scale 5G network

Published

on

STOCKHOLM: Telecom equipment manufacturer Ericsson said Wednesday it had launched the first European large scale commercial 5G network together with Swiss operator Swisscom, as Ericsson posted a first quarter profit boosted by sales in North America.

The Swedish supplier of network equipment said in a statement that the 5G network, launched in 54 cities in Switzerland, had been switched on just after midnight on April 17, after Swisscom secured a license to operate a 5G network in the country.

Ericsson made the announcement as it reported a first quarter net profit of 2.4 billion kronor ($260 million, 230 million euros), compared to a net loss of 725 million kronor in the corresponding quarter a year ago.

Net sales grew to 48.9 billion kronor, up from 43.4 billion in Q1 of 2018.

Chief executive Borje Ekholm said growth had primarily been driven by sales in North America.

“To date we have publicly announced commercial 5G deals with 18 named operator customers, which, at the moment, is more than any other vendor,” Ekholm said in a statement.

Ekholm also said that as 5G technology was being rolled out, the company would continue to incur costs for field trials and they were expecting large-scale deployments of 5G to begin in parts of Asia by the end of 2019.

“Combined, this will gradually impact short-term margins but strengthen our position in the long term,” he said.

Shares in Ericsson traded up more than three percent on the Stockholm stock exchange following the release of the earnings report, hitting a four-year high in early trading on Wednesday.

Ericsson, one of Chinese telecom giant Huawei’s main rivals in the 5G market, said earlier this year it hadn’t felt any effects from US pressure on countries to ban Huawei’s equipment amid fears that it could compromise the security of the mobile phone networks.

Intel withdraws from 5G smartphone modem business

Published

on

SAN FRANCISCO: US electronics giant Intel said Tuesday it was withdrawing from the 5G smartphone modem business, hours after Apple and American microchip manufacturer Qualcomm announced they had clinched an agreement to end a battle over royalty payments.

The modems that connect smartphones to telecommunications networks were at the heart of the battle between Apple and Qualcomm.

Intel said it will “complete an assessment of the opportunities for 4G and 5G modems in PCs, internet of things devices and other data-centric devices,” while pursuing investment opportunities in its 5G network infrastructure business.

“5G continues to be a strategic priority across Intel, and our team has developed a valuable portfolio of wireless products and intellectual property,” CEO Bob Swan said in a statement.

“We are assessing our options to realize the value we have created, including the opportunities in a wide variety of data-centric platforms and devices in a 5G world.”

The company said it would meet commitments to customers for its existing 4G smartphone modem product line, though it has no plans to launch 5G smartphone modem products, including those previously set to premiere in 2020.

Currently under deployment, ultra-fast 5G wireless networks require terminals equipped with 5G models and specific network infrastructure.

Apple, which had fought a multi-front brawl with Qualcomm for two years, had turned to Intel before reaching the agreement with Qualcomm.
