Space station by China, Tiangong (Heavenly Palace) is expected to be operational by 2022. China is partnering with multiple nations, many of which are already partners of the US on the International Space Station, for conducting scientific experiments onboard Tiangong. These countries include France, Germany, Japan and even developing nations like Kenya and Peru.
“China is rapidly building what they call the ‘Chinese International Space Station,’ and they’re rapidly marketing that space station to all of our international partners,” said NASA chief Jim Bridenstine. “It would be a tragedy, if, after all of his time, and all of this effort, we were to abandon low Earth orbit and cede that territory.”
Bridenstine mentioned the US’ necessity in maintaining the position. He suggested that funds to NASA can eventually be used to pay companies to set up a space station. NASA would then act as “one of several customers” and hence will have a presence in the low-Earth orbit at a much lower cost.
He stressed that this was vital to “ultimately not cede that territory to another country that doesn’t have our interests at heart.”
A Chinese Long March-4B carrier rocket carrying two environmental monitoring satellites was launched from Taiyuan Satellite Launch Center in north China’s Shanxi Province at 11:23 a.m. Sunday.
China’s fastest subway train — traveling at 160 kilometers an hour — debuted in Guangzhou, the capital of South China’s Guangdong Province, on Friday, according to media reports.
The subway train will be put into service at Guangzhou Metro’s No. 18 and No. 22 metro lines, which are currently still under construction. Once it is put into service, it will take only 25 minutes and 30 minutes from Nansha Free Trade Zone to the South Guangzhou train station and East Guangzhou train station, respectively.
The two lines will extend to Guangdong’s Zhuhai, Zhongshan and Dongguan cities in the future.
The train — manufactured by CRRC Zhuzhou Locomotive Co — is also the first subway to travel at 160 kilometers an hour in the Guangdong-Hong Kong-Macao Greater Bay Area.
The train uses the most advanced design techniques, technological protocols and innovation. It also introduces an intelligent operation and maintenance system based on big data and cloud computing, according to a report by news website qq.com.
The Guangzhou railway authority has ordered 40 such trains to run on its No. 18 and No. 22 lines from CRRC. The next delivery after the first train will begin in October.
