Microsoft co-founder Bill Gates said Friday he is stepping down from the company's board to focus on philanthropy.
Gates was Microsoft's CEO until 2000 and since then has gradually scaled back his involvement in the company he started with Paul Allen in 1975.
He transitioned out of a day-to-day role in Microsoft in 2008 and served as chairman of the board until 2014.
The billionaire announced Friday that he's leaving the Microsoft board entirely as well as his seat on the board of Berkshire Hathaway, the conglomerate headed by fellow billionaire Warren Buffett.
Gates said he plans to dedicate more time to the Bill and Melinda Gates Foundation. He will also remain a technology adviser to Microsoft CEO Satya Nadella and other company leaders.
China launched a new satellite of the BeiDou Navigation Satellite System (BDS) from the Xichang Satellite Launch Center in southwest China's Sichuan Province at 7:55 p.m. Monday (Beijing Time), only one step away from completing the whole global system.
The satellite, the 54th of the BeiDou family, was sent into a geostationary orbit as planned by a Long March-3B carrier rocket.
China began to construct its navigation system, named after the Chinese term for the Big Dipper constellation, in the 1990s and started serving the Asia-Pacific Region in 2012. At present, all the first generation BDS-1 satellites have ended operations, and a total of 54 BDS-2 and BDS-3 satellites have been sent into space.
Compared with other navigation systems in the world, the design of the BDS constellation is unique, including medium earth orbit, inclined geosynchronous earth orbit and geostationary earth orbit satellites.
The BDS-3 system will consist of a total of 30 satellites, including 24 medium earth orbit satellites, three geostationary earth orbit satellites and three inclined geosynchronous earth orbit satellites.
The newly launched satellite is the second geostationary earth orbit satellite of the BDS-3 system, and the last one is expected to be launched in May.
The satellite and the carrier rocket were developed by the China Academy of Space Technology (CAST) and the China Academy of Launch Vehicle Technology, respectively.
Space engineers have overcome difficulties during the novel coronavirus epidemic to ensure the success of the mission.
Monday's launch was the 327th mission of the Long March rocket series.
The new satellite has the most functions and signals, the largest size and the longest designed life span among all the BDS-3 satellites, said Chen Zhonggui, chief designer of BDS-3 satellites from CAST.
The satellite is based on the Dongfanghong-3B platform, currently one of the largest satellite platforms being used in China, and can carry more fuels to ensure its long life, said Chen.
The satellite has integrated the functions of navigation and communication. The accuracy of dynamic positioning can reach the decimeter level, according to Liu Tianxiong, deputy chief designer of BDS-3 satellites.
It can provide services for the driverless vehicles, accurate berthing of ships, as well as takeoff and landing of airplanes. It will be widely used in the fields of communication, electric power, finance, mapping, transportation, fishery, agriculture and forestry.
The ability of short message communication has been improved 10 times on this satellite. Users can send a message of over 1,000 Chinese characters at one time as well as pictures via the satellite, quite useful in emergencies.
The satellite's ability to receive signals has also been greatly improved, which could help miniaturize users' terminals, said Pan Yuqian, one of the satellite's designers.
China aims to complete the construction of the BDS constellation in May and provide high-precision, reliable positioning, navigation and timing services anywhere in the world.
A new study of NASA and U.S. universities on carbon dioxide emissions for 20 major cities around the world has provided the first direct, satellite-based evidence that as a city's population density increases, the carbon dioxide emission per person declines.
According to a release of NASA's Jet Propulsion Laboratory (JPL) on Friday, the study also demonstrates how satellite measurements can give fast-growing cities new tools to track carbon dioxide emissions and assess the effect of policy changes and infrastructure improvements on their energy efficiency.
Cities account for more than 70 percent of global carbon dioxide emissions associated with energy production, and rapid, ongoing urbanization is increasing their number and size. But some densely populated cities emit more carbon dioxide per capita than others.
Atmospheric scientists Dien Wu and John Lin of the University of Utah in Salt Lake City teamed with colleagues at NASA's Goddard Space Flight Center in Greenbelt, Maryland, and the University of Michigan in Ann Arbor.
They calculated carbon dioxide emissions per capita for 20 urban areas on several continents using recently available carbon dioxide estimates from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite.
Researchers used satellite-derived estimates of the amount of carbon dioxide present in the air above an urban area as the satellite flies overhead.
"Other people have used fuel statistics, the number of miles driven by a person or how big people's houses are to calculate per capita emissions," Lin said. "We're looking down from space to actually measure the carbon dioxide concentration over a city."
Published Feb. 20 in the journal Environmental Research Letters, the study found that cities with higher population densities generally have lower carbon dioxide emissions per capita.
The researchers believe new data from OCO-2's successor, OCO-3 -- which was launched to the International Space Station last year -- along with future space-based carbon dioxide-observing missions, may shed light on potential solutions to mitigating cities' carbon emissions.
Finnish telecoms equipment maker Nokia's president and CEO Rajeev Suri will step down, while Pekka Lundmark, the outgoing president and CEO of Finnish energy firm Fortum, will replace him, Nokia said Monday.
Suri will leave his current position on Aug. 31 and serve as an adviser to the Nokia board until Jan. 1, 2021.
Noting that he has been serving Nokia for 25 years, Suri said now he wants to do something new, adding that Lundmark is an excellent choice for the company.
In a written statement, Lundmark described Nokia as a "unique company that has much potential and talented people."
Lundmark, 57, held executive positions at Nokia between 1990 and 2000 and become the CEO of Fortum in 2015, and is also the chairman of the board of the Confederation of Finnish Industries.
Walton, a local electronics and ICT product manufacturer, has begun exporting ‘Made-in-Bangladesh’ smartphones to the United States (US) and air-conditioner to India.
Finance Minister AHM Mustafa Kamal inaugurated the export process on Sunday while visiting factories of Walton Hi-Tech Industries Ltd at Chandra of Gazipur. Five other projects, including an elevator factory, were launched in his presence.
“Countrymen are happy with the service of Walton’s products. The company is leading Bangladesh to the US market for the first time. We’ll see Bangladeshi products in US markets thanks to Walton,” he said during the visit.
Minister Kamal was accompanied by Posts and Telecommunications Minister Mustafa Jabbar and State Minister for Information and Communication Technology Division Zunaid Ahmed Palak.
Walton Hi-Tech Industries Limited Chairman SM Nurul Alam Rezvi, Vice-Chairman SM Ashraful Alam, Director SM Mahbubul Alam, among others, were present.
