China plans another Moon mission in 2019, targets Mars in 2020: Report

Riding on its success of landing a rover on the far side of the Moon earlier in January, China’s space agency is planning to launch another mission to the Moon by the end of 2019 and a mission to Mars as early as 2020, the media reported.

The plans underscore China’s ambitions in space at a time when the US is curtailing NASA’s budget and increasingly handing over space exploration to commercial adventurers, the Washington Post reported on Monday.

The China National Space Administration is working to send a probe to the Red Planet, said Wu Yanhua, deputy chief of the agency.

“China will carry out its first-ever exploration mission to Mars around 2020,” he said.

On January 3, China’s robotic spacecraft Chang’e-4 landed on the far side of the moon, a first in the human history of space exploration.

The 1.3-tonne lander, which made a soft landing on the Moon, put potato seeds and silkworm eggs housed in a chamber, and fed natural light and nutrition, on the Moon.

The space agency plans to launch a Chang’e-5 mission at the end of 2019 with the goal of collecting samples from the near side of the moon, Wu said. They would be the first samples retrieved since 1976.

China is also building its own space station, called Tiangong or Heavenly Palace, which is expected to be operational in 2022. But the agency is still deciding whether to send astronauts to the Moon, Wu said.

It also deployed a small rover called Yutu-2, or Jade Rabbit-2, to explore the surrounding lunar terrain, which is believed to be older than that on the near side.

“All these are first-time breakthroughs for humankind,” Wu said, adding “they are bound to make significant impacts on both China and the world.”

Meanwhile, China also said it has shared data with NASA about the Chang’e-4 lunar mission.

That claim could not be immediately substantiated, but it could raise eyebrows on Capitol Hill because NASA and the Chinese agency are prohibited from cooperating without congressional approval, the report said.

“Expanded international cooperation is the wish of all scientists,” Wu said. “It takes joining of forces among the world’s big space powers to really make a difference in human space exploration.” (IANS)

A study published on Wednesday in the Journal of Medical Virology showed that snake is the most probable wildlife animal reservoir for the novel coronavirus that had caused 17 deaths in central China’s Hubei Province.

Scientists from Peking University Health Science Center School of Basic Medical Sciences, the First affiliated Hospital of Guangxi University of Chinese Medicine, Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine, Ningbo University’s School of Medicine, and Wuhan University of Bioengineering carried out a comprehensive analysis on the existing sequences of the newly identified coronavirus, the Xinhua news agency reported.

They used a method called “relative synonymous codon usage” (RSCU) bias to compare RNA sequences of different animal species.

Snake was one of the animals being sold in Wuhan’s Huanan Seafood Wholesale Market before its closure. The market is believed to be related to most of the infected cases.

Results obtained from the analyses suggested that the new virus 2019-nCoV appeared to be a recombinant virus between the bat coronavirus and an origin-unknown coronavirus.

The recombination occurred within the viral spike glycoprotein, which recognizes cell surface receptor. Additionally, their findings suggested that snake is the most probable wildlife animal reservoir for the 2019-nCoV based on its RSCU bias resembling snake compared to other animals.

Taken together, the research results suggested that homologous recombination within the spike glycoprotein may contribute to cross-species transmission from snake to humans.

Glycoprotein is a group of conjugated proteins containing small amounts of carbohydrates.

Chinese health authorities have posted the full genome of 2019-nCoV in the genetic sequence database of U.S. National Institutes of Health and the Global Initiative on Sharing All Influenza Data, according to U.S. Centers for Disease Control and Prevention (CDC). (IANS)
