Dhaka, June 26 (UNB) - Nasa has put a miniaturised atomic clock in orbit that it believes can revolutionise deep-space navigation, reports BBC.
About the size of a toaster, the device is said to have 50 times the stability of existing space clocks, such as those flown in GPS satellites.
If the technology proves itself over the next year, Nasa will install the clock in future planetary probes.
The timepiece was one of 24 separate deployments from a Falcon Heavy rocket that launched from Florida on Tuesday.
The other passengers on the flight were largely also demonstrators. They included a small spacecraft to test a new type of "green" rocket fuel, and another platform that aims to propel itself via the pressure of sunlight caught in a large membrane; what's often called a "lightsail".
But it is the mercury-ion atomic clock, developed at Nasa's Jet Propulsion Laboratory (JPL), which has had most attention.
Today, deep-space probes are tracked across the Solar System via radio signals.
These signals are sent from Earth and are immediately returned by the spacecraft. The very precise time taken for the speed-of-light messages to echo back enables navigators to work out the mission's exact position and to command the necessary course corrections.
But if probes carried their own atomic clocks, this two-way system could be reduced to one-way, and the missions' onboard computers would then make all the necessary navigational calculations.
The atomic clocks currently used on Earth for deep-space navigation are refrigerator-sized. JPL's engineers have shrunk this down to something that can easily be accommodated on a spacecraft.
Deputy principal investigator Jill Seubert said "self-driving spacecraft" were one of the top technologies needed to put humans on Mars.
"Autonomous onboard navigation means that a spacecraft can perform its own navigation in real-time without waiting for directions to be sent from navigators back here on Earth. And with this capability, a human-crewed spacecraft can be delivered safely to a landing site with less uncertainty in their path," she told reporters.
Don Cornwell, from Nasa's Space Communications and Navigation Program, added: "Of course, for a spacecraft travelling well beyond Earth orbit, the smallest clock inaccuracies can lead to large navigational errors. But [the new clock] has a high degree of clock stability, meaning it can maintain its accuracy over many years.
"The deep space atomic clock's design should gain or lose less than 2 nanoseconds per day, or an error of one second in nine million years."
The development of the spacecraft chassis, or bus, that is carrying the clock was begun by the British manufacturer Surrey Satellite Technology Limited at its US division, which was then later sold to the American General Atomics company.
Surrey itself had an interest in six other spacecraft launched on Monday's Falcon Heavy.
The UK firm assembled this sextet of platforms to be part of a constellation known as FORMOSAT-7. It is a joint US-Taiwanese initiative to monitor the weather by interrogating the way radio signals from GPS satellites are affected as they pass through the atmosphere.
Tuesday was the third time a Falcon Heavy had flown. The rocket is essentially three Falcon-9 rockets strapped together.
As is customary now for the rocket operator SpaceX, the three boosters were commanded to come back to Earth under control once they had finished the job of sending the multi-satellite mission on its way.
Two of the boosters successfully landed back at Cape Canaveral. The third just missed its touchdown target on a drone ship out in the Atlantic.
Dhaka, June 26 (UNB) - Kim Phan, the Global Esports Director of American video game developer and publisher Blizzard, has left the firm to pursue a "new endeavour" in the industry, reports NDTV.
It is still not clear who would be filling Phan's old post. The departure was announced by Phan on a Team Liquid forum.
"Fifteen years ago, I discovered the TeamLiquid.net forums and became a part of this amazing family. This site has been around longer than I have been in e-sports, and a big reason why I've decided to make this post here today... Going forward, I will be pursuing a new endeavour within the gaming industry. My last day with Blizzard was Friday, June 14th. As I hang up my sword and shield, I look forward to a bright future and wish all my Blizzard friends and family the very best," Phan wrote on the forum.
Engadget reported the news over the weekend, and added, "However, things clearly haven't gone as well as they could in recent months. On top of the departures of Phan and Nanzer, there have been rumours of low morale and additional resignations... The company also scuttled Heroes of the Storm e-sports plans in December. Stability isn't Blizzard's strong suit at the moment, even if efforts like Overwatch League continue to draw in large crowds."
Phan is the second high-profile executive at Blizzard to exit the company within the last month.
On May 25, Overwatch League (OWL) Commissioner Nate Nanzer announced his resignation, according to esportsobserver.com.
Dhaka, Jun 25 (UNB)- Huawei industries and its 5G services have been gaining popularity in commercial adoption, said Ryan Ding, Executive Director of the Board and President of the Carrier BG of Huawei.
Since the first half of this year, South Korea, UK, Switzerland, Italy, and Kuwait, have commercially launched 5G networks, 2/3 of which were constructed by Huawei, said Ryan Ding, Executive Director of the Board and President of the Carrier BG of Huawei, he added.
Ryan placed a keynote speech titled Industries + 5G, Enabling New Growth at the summit during MWC Shanghai 2019, Huawei held the 5G is ON Summit based on the theme of "5G-driven Digital Upgrades".
"Huawei has so far gained 50 5G commercial contracts and shipped more than 150,000 base stations," Ding said.
Industries are starting to embrace 5G and 5G is starting to explode into prominence by promoting a comprehensive digital transformation and improving efficiency in many industries. Huawei's modular and full-series solutions will put operators in unique positions to build green, converged, and ultra-lean 5G commercial networks that drive continuous growth."
5G Accelerates Digital Transformation, Enables New Business Growth.
Traditionally, live TV broadcasting requires broadcasting vehicles worth at least CNY80 million and 150 onsite workers for recording, editing, transmission, and broadcasting -- not to mention the high costs arising from costly satellite transmission.
Huawei offers a broad range of modular and full-series solutions, including Massive MIMO, Blade Site, and BookRRU, to help global operators build green, converged, and ultra-lean 5G networks. Their power consumption is so low that per-bit energy efficiency is 25 times higher.
MWC Shanghai 2019 will be held in Shanghai, China from June 26–28, 2019. Huawei's exhibition areas include halls E10 and E70 in Hall N1 and the Innovation City zone at booth ICA01 in Hall N5 of Shanghai New International Expo Center (SNIEC).

Berlin, June 25 (AP/UNB) — Scientists in Europe say they've successfully transferred a test tube rhino embryo back into a female whose eggs were fertilized in vitro, as part of an effort to save another nearly extinct sub-species of the giant horned mammal.
Thomas Hildebrandt of the Leibniz Institute for Zoo and Wildlife Research in Berlin said Tuesday the procedure was performed last month on a southern white rhino at Chorzow Zoo in Poland.
Hildebrandt is part of an international team trying to save the northern white rhino. The team is hoping to get permission from Kenya to harvest eggs from the last two surviving female northern white rhinos soon.
He told reporters that "this is the first positive proof that the entire procedure we've developed in theory can be successful."
