The Long March-7 Y4 rocket carrying the Tianzhou-3 blasted off at 3:10 p.m. (BJT) on September 20, 2021, from the Wenchang Spacecraft Launch Site in south China’s Hainan Province. It carried about six tonnes of goods, including food items and spacesuits, to the country’s under-construction space station. Six and a half hours later, the cargo spacecraft docked with core module Tianhe at 10:08 p.m. (BJT) on the same day.

The Tianzhou-3 separated from the space station core module Tianhe on July 17, 2022, after completing all assigned assembly tasks.

It is the third mission of China’s Tianzhou-class unmanned cargo spacecraft and the second resupply mission to the space station after Tianzhou-2.

BERLIN, Sept. 1 (Xinhua) — As one of the world’s leading trade fairs for consumer electronics, the five-day IFA 2023 opened here on Friday with over 2,000 exhibitors from 48 countries and regions, a much greater scale than last year.

“In addition to all the historic brands you know and love at IFA, 30 percent of exhibitors are new this year,” Oliver Merlin, managing director of IFA Management, said in a statement issued on Friday.

According to the organizer, sustainability is a major priority of the trade fair. Ahead of IFA’s 100th birthday next year, the 2023 event for the first time dedicated an exhibit area to highlighting sustainability. Besides, it will have multiple forums to discuss how consumer electronic enterprises could develop in a more sustainable approach.

According to IFA official website, nearly 1,300 Chinese exhibitors have registered in this year’s event. Chinese companies such as Hisense, TCL and Haier have occupied some of the largest exhibit areas with various products.

While delivering a keynote speech on Friday, Hisense Group’s President Yu Zhitao said the company looks forward to expanding its overseas market share.

“In order to be more and more user-centric, we are upgrading and optimizing our products and services to meet consumer needs,” he said.

The inaugural International Congress of Basic Science (ICBS) took place in Beijing on Sunday with a theme of “Advanced Science for Humanity.”

The conference lasts two weeks, with over 800 top-notch scientists and scholars gathering to discuss frontier research in the fields of mathematics, theoretical physics, theoretical computer and information science.

Shing-Tung Yau, president of the International Congress of Basic Science and a Fields Medal winner, said in the opening speech that he is expecting the academic exchanges at the conference to contribute to the development of the world’s basic science knowledge. “I hope the renowned international scholars learn more about China and the young scholars learn from the best and set their goals.”

The scientists attending the conference include eight Fields Medal winners, four Turing Award winners, one Nobel Prize laureate and more than 50 academicians from different countries.

The conference is hosted by the People’s Government of Beijing Municipality, the Ministry of Science and Technology of China, China Association for Science and Technology, and the International Consortium of Chinese Mathematicians.

European Space Agency launches Jupiter moons explorer

PARIS, April 14 (Xinhua) — The European Space Agency (ESA) launched on Friday an Ariane 5 rocket carrying its Jupiter Icy Moons Explorer (Juice) from Europe’s Spaceport in French Guiana.

According to the ESA, the successful launch marks the beginning of an ambitious voyage to uncover the secrets of the ocean worlds on Jupiter’s three largest moons: Europa, Ganymede, and Callisto, which hold quantities of water under their surfaces in volumes far greater than in Earth’s oceans.

“These planet-sized moons offer us tantalizing hints that conditions for life could exist other than here on our ‘pale blue dot’,” the ESA said in its press release.

Over the next two-and-half weeks, Juice will deploy its various antennas and instrument booms, including a 16-meter-long radar antenna, a 10.6-meter-long magnetometer boom, and various other instruments that will study the environment of Jupiter and the subsurface of the icy moons, the agency said.

Juice will also monitor Jupiter’s complex magnetic, radiation, and plasma environment in depth and its interplay with the moons, thus studying the Jupiter system as an archetype for gas giant systems across the Universe.

Juice has been designed for an eight-year cruise with flybys of Earth and Venus to slingshot it to Jupiter. It will make 35 flybys of the three large moons while orbiting Jupiter, before changing orbits to Ganymede, said the agency.
