Beijing, Aug 8 (Xinhua/UNB) -- China's lunar rover Yutu-2 has driven 271 meters on the far side of the moon to conduct scientific exploration on the virgin territory.
Both the lander and the rover of the Chang'e-4 probe switched to its dormant mode for the lunar night on Wednesday (Beijing time), according to the Lunar Exploration and Space Program Center of the China National Space Administration.
China's Chang'e-4 probe, launched on Dec. 8, 2018, made the first-ever soft landing on the Von Karman Crater in the South Pole-Aitken Basin on the far side of the moon on Jan. 3.
A lunar day equals 14 days on Earth, a lunar night the same length. The Chang'e-4 probe switches to dormant mode during the lunar night due to lack of solar power.
During the eighth lunar day of the probe on the moon, the scientific instruments on the lander and rover worked well, and a new batch of scientific detection data were sent to the core research team for analysis.
Beijing, Aug 8 (Xinhua/UNB) -- China's super-thin rubidium atomic clock, which is just 17 millimeters thick, has been put into mass production, said its manufacturer Thursday.
The clock, developed in 2018 by a research institute under the China Aerospace Science and Industry Corporation Limited, is the key to the positioning and timing accuracy of BeiDou navigation satellites.
Compared with the previous generation, the new clock is smaller in size but performs better. It adopts a plug-in design, making it easy to insert and remove on circuit board. With stronger resistance to high temperatures, it can work at 70 degrees Celsius.
The clock can be used in fields such as aviation, aerospace and telecommunications. According to its developers, the ultra-accurate clock will have a broader market prospect in the future.
A large number of self-developed rubidium and hydrogen atomic clocks have been carried by satellites that provide accurate positioning for China's BeiDou Navigation Satellite System.
The atomic clocks are the workhorses that send synchronized signals so sat-nav receivers can triangulate their position on Earth.

San Francisco, Aug 7 (Xinhua/UNB) -- Apple sent out invitations on Tuesday to some select users to apply for its credit card released in partnership with investment bank Goldman Sachs.
The users who got the chance to first try the Apple Card had filled out a "Notify Me" form on the Apple website, while other U.S. customers have to wait till later this month when the credit card will be fully launched.
An iPhone has to be updated to iOS 12.4 or later to sign up for the credit card.
According to a "how-to" video released by the tech giant, it takes just minutes to apply for the card: simply open the Wallet app on one's iPhone, tap the "add" sign on the top right corner, choose Apple Card, fill our some basic information and click the accept button. Bingo, an Apple Card is added to your iPhone e-wallet.
On its face, the Apple Card behaves a lot like Apple Pay, the mobile payment system the company introduced four years ago, tech news website Wired reported.
The "virtual card" lives inside the Apple Wallet and functions as contactless payment system, Wired said. However, customers can also request a physical titanium card.
Apple claimed on its website that their credit card gives its customers "a new level of privacy and security" as all the advanced security technologies of Apple Pay, such as Face ID or Touch ID, are built right in the device.
In addition, the physical card doesn't bear any numbers on it so it's unlikely to be stolen.
On top of that, Apple said it never sees information about users' transactions. All the transaction history and spending summaries are generated solely in the Wallet app on the customer's iPhone.
However, Goldman Sachs, the issuing bank, will use customers' data to approve purchases and check for things like fraud.
According to business news channel CNBC, the credit card is "part of Apple's broader push to expand its services business from its 1.4 billion active Apple devices."
Meanwhile it offers Goldman Sachs "an opportunity to expand its reach into retail banking" as this is the bank's first consumer credit card aside from its vast institutional client services, CNBC added.
Last week, Apple disclosed a record quarterly revenue of 53.8 billion U.S. dollars for the third quarter ended on June 30.
"This was our biggest June quarter ever - driven by all-time record revenue from Services, accelerating growth from Wearables, strong performance from iPad and Mac and significant improvement in iPhone trends," said Apple CEO Tim Cook in a press release.
