China's Tianwen 1 Mars probe (探测器)conducted its fourth orbital (correction on Friday evening, as the spacecraft makes ready for its arrival in orbit around Feb. 10, according to the China National Space Administration.
The name comes from the long poem Tianwen, meaning Heavenly Questions or Questions to Heaven, written by Qu Yuan, one of the greatest poets of ancient China. In Tianwen, this name conveys the Chinese nation's steady effort in pursuing truth and culture of exploring nature and the universe. CNSA also unveiled (发布)the logo of China's planetary exploration missions, featuring the letter C , signifying China, international cooperation and capacity of entering space.
Tianwen 1 has flown for 197 days and more than 465 million kilometers on its journey to the planet. It is now around 184 million km from Earth and 1. 1 million km from Mars. Depending on the two planets, orbits, Mars is between 55 and 400 million km from Earth. Mars probe Tianwen 1 is seen in its first selfies in space on Oct. 1,2020. The administration also published a black-and-white picture of Mars taken by Tianwen 1 , the first snapshot (抓拍的照片)from the Chinese craft.
Tianwen 1 , the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.
A successful landing would make China only the second nation lo place a spacecraft on the Martian planet. China would also be the first to successfully orbit, land and deploy (部署)a vehicle in the same mission. According to experts, searching for signs of life on Mars will be the first and foremost scientific goal. China is open and inclusive in the development of its space technology not least because it believes that the exploration of outer space should help build a community with a shared future for mankind.

China’s Mars rover, Tianwen-1, will likely attempt to land at a site in northeastern Mars, according to a new paper published just days ahead of the mission’s launch. The paper was written by team members of China’s Tianwen-1 Mars mission, which aims to send an orbiter and a rover to the Red Planet.
The study reveals new details about Tianwen-1, outlining its intended landing area, science goals and the names of instruments aboard the spacecraft. It also stresses the historic nature of the mission: Not only is Tianwen-1 China’s first fully homegrown Mars mission, it’s also the first to carry both an orbiter and a rover.
Tianwen-1 means “questions to heaven” and was taken from the title of a poem by Qu Yuan (340 — 278 BC). The spacecraft will reach Mars in February 2021, at the same time as NASA’s Perseverance rover and the United Arab Emirates’ Hope orbiter launched on Sunday (July 19). However, China’s rover will remain attached to the orbiter for two to three months before attempting its landing, according to the paper.
The chosen landing area is Utopia Planitia, a huge basin formed by a large impact far back in Mars’ history that was also the region where NASA’s Viking 2 lander touched down in 1976. China had isolated a part of the vast plain as a landing area, which means there will be more time and atmosphere for the entry spacecraft to slow down and safely land on the surface. The latitude is also suitable for receiving enough sunlight to power the 240 kilograms rover. The relatively smooth surface will also be helpful for roving. The mission also benefits from the engineering heritage of China’s Chang’e lunar exploration program, the paper noted.
The Tianwen-1 orbiter will operate in a polar orbit in order to map Mars. The rover will also investigate the surface soil characteristics and water-ice distribution with its own Subsurface Exploration Radar. It will also analyze surface material composition and characteristics of the Martian climate and environment on the surface.
1.What’s the purpose of the passage?A.To lay out key details about Tianwen-1.B.To state how Tianwen-1 was invented.C.To stress the historic meaning of Tianwen-1.D.To analyze characteristics of the Martian climate.2.What is most special about Tianwen-1 according to Para. 2 & 3?A.It was named after Qu Yuan, a famous poet in Chinese history.B.It will reach Mars at the same time as NASA’s Viking 2.C.It will remain for 2 or 3 months on Mars.D.It will complete orbiting and roving in a Mars mission.3.Why is Utopia Planitia chosen as the landing area of Tianwen-1?A.The rare air there is suitable for the flight of Tianwen.B.The area can protect Tianwen-1 from too much sunlight.C.It has relatively smooth surface, which is helpful for roving.D.There is no spacecraft successfully landing there in history.4.The last paragraph states mainly ___________.A.Tianwen-1’s historic contributionsB.Tianwen-1’s new radar instrumentsC.Tianwen-1’s academic advantagesD.Tianwen-1’s scientific goals
