China launched its fifth Beidou orbiter into space on Sunday morning, moving it one step closer to its goal of building a navigation(导航) and positioning satellite network.
The Beidou, or Compass, system is being built to rival the US-developed GPS, the European Union's Galileo and Russia's Global Navigation Satellite System. It can allow travelers, drivers and military officials to know their locations.
The fifth orbiter was launched on top of a Long March 3A carrier rocket at 5:30 am on Sunday from Xichang of Southwest China's Sichuan province.
It is the third Compass satellite launched this year, following launches on Jan 17 and June 2.
The short interval of less than two months since the last launch demonstrated that "the country is stepping into a busy period of launching the Compass satellites", an unnamed official in charge of the project said last month.
The first two orbiters were launched in 2007 and 2009 respectively.
Sun Jiadong, the Beidou program's chief designer, said on June 21 in a TV interview that China would launch 13 to 15 Beidou navigation satellites into orbit by 2012 to form a network that provides regional service covering the neighboring areas.
And in about 10 years, the network would be expanded to include more than 30 satellites covering the globe, he said.
The system is a crucial part of the country's space infrastructure for providing navigation and positioning services in transportation, meteorology, petroleum prospecting, forest fire monitoring, disaster forecasting, telecommunications and public security.
In addition, a global positioning system is crucial to any country's national security and defense, said Ran Chengqi, an official in charge of the program, referring to the fact that the US initially built its GPS system for military purposes.
It is unimaginable for China to go without such a system, he said.
Earlier reports cited(引用) Song Xiaojun, a Beijing-based military expert, as saying that 90 percent of the world's current weapons systems need a global positioning system.
1.This news report was probably released________.
A.in January, 2010 B.in June, 2010 C.in July, 2010 D.in August, 2010
2.The Compass System is expected to finally cover________in the future.
A.China B.China and its neigh boring areas
C.Asia, Europe and Oceania D.the earth
3.At the very beginning, the GPS system was built to help________.
A.military officers to judge their locations B.travelers to know their locations
C.drivers to reach their destinations easily D.hunters to find wild animals smoothly

China launched its second space laboratory, the Tiangong II, on Sept 15, which space officials say will become the country’s largest scientific platform in space to date.
The space lab was lifted off atop a Long March 2F carrier rocket from the Jiuquan Satellite Launch Center in Gansu province at 10:04 pm. Around 20 minutes later, the mission was declared a success.
The Tiangong II did preparations in space for about one month and then the Shenzhou XI manned spacecraft rocketed two astronauts to the lab on October 17th. The pair will make it their home for 30 days before being returned to Earth.
The lab’s predecessor, Tiangong I, was launched in September 2011 and was used mainly to test technology involved in space docking.
By comparison, the Tiangong II will be used to conduct more than 40 scientific and technological experiments together with the Shenzhou XI. That’s many times more than those carried out by the Tiangong I and the three previous Shenzhou spacecraft, according to Wu Ping, deputy director of the China Manned Space Agency. China’s manned space program has entered a “new phase of application and development,” he said.

Beijing museum launches outer space into cyberspace
The National Museum of China has taken a variety of measures on its website and WeChat account, creating virtual tours for its current and permanent exhibitions, uploading audio of previous educational courses and providing more social media posts to detail the star items in its collection. It has gone a further step by launching an exhibition entirely online with the help of advanced technology such as 3D modeling and 5G.
The exhibition, titled Dongfanghong Forever, charts the progress China has made in aerospace over half a century. The show opened on April 24, which is marked as the country’s Space Day, when the satellite Dongfanghong 1 was launched in 1970.
The success of Dongfanghong 1 entering its present orbit not only registered the country’s first steps in exploring outer space but the event also made China the fifth country in the world to develop a satellite on its own and put it in space.
The online exhibition is expected to run for a long time, and people can visit it on the museum’s website at any time. It is the first such virtual show the museum has staged. It reviews “three critical moments in the country’s space exploration-the development of Dongfanghong 1, the liftoff of China’s first manned spacecraft, Shenzhou V, in 2003 and the landing of the Chang’e 4 lunar probe in 2019”.
The exhibition gives a view of Dongfanghong 1 orbiting in the form of digital simulation (模拟). Viewers can also watch television interviews of scientists involved in the mission and documentary footage filmed in 1970, as well as hear Dongfanghong (The East is Red), a song popular in China hailing Mao Zedong, played by the satellite.
The exhibition will motivate more people to engage in the country’s ambitious course of space exploration.

Humans have launched themselves into the outer space. They’ve landed on the moon. They’ve built habitable space stations that orbit the Earth. The next giant leap for mankind is to reach another planet – specifically, Mars.
The problem is that it’s no easy task. The planet is 586 times further away from the Earth than the moon, and it’ll take around 180 to 220 days to reach Mars, depending on where each planet is in its orbit. Such long periods in space have suggested many potential health problems, including hormonal changes, skin conditions, and muscle and bone deterioration (损耗).
Here’s where some furry friends come in. A wide range of animals have been in space, from fruit flies and spiders to cats, and dogs. Such experiments began as far back as the late 1940s in first tests to see if living things could withstand the extreme g-force (重力) of a rocket launch.
Mice continue to play a very important part in space experiments, mainly because the animals make excellent test subjects. They’re small, which makes them inexpensive and easy to care for. In addition, their size and short life span make it possible to do the equivalent of several human years of tests in a much shorter time. Finally, because mice are mammals, they share many common characteristics with humans in terms of genetics, biology and behavior.
Astromice have hit the headlines recently, as a team of scientists led by Betty Nusgens, professor of biology at the University of Liege in Belgium, found that the mice suffered a 15 percent thinning of their skin after 91 days aboard the International Space Station (ISS).
This experiment was part of a wider NASA mission (任务) called the Mice Drawer System (MDS). The Italian Space Agency developed the facility, which allows six mice to be housed, monitored, and automatically fed and watered aboard the ISS, among which three survived during the mission.
The mice have participated in 20 separate experiments, to study such effects as osteoporosis (骨质疏松症), anemia (贫血) and heart health.
Results for the 20 experiments are coming in gradually. But it’s clear that mice continue to play an important role in the ongoing quest to conquer the final frontier.
1.We can infer from Paragraphs 2-3 that ______.
A. Mars is the farthest planet away from Earth discovered so far
B. the journey to Mars could put humans’ health at risk
C. it was in the late 1940s that animals were first sent to the ISS
D. animals that have been sent into space have mostly survived
2.The underlined word “withstand” in Para.3 means _________.
A.set up B. hold up
C. work out D. come across
3.According to Betty Nusgens and her team, the mice aboard the ISS ______.
A. suffered the loss of part of their skin
B. all survived for the duration of the mission
C. were fed and watered by the astronauts
D. participated in 20 experiments that made great breakthroughs
4. The main purpose of the article is to _____.
A. describe the role mice play in scientific research
B. report on the results of the Mice Drawer System
C. analyze how mice could pave the way to Mars
D. change people’s traditional attitudes toward mice

Today, China has conducted its first 3D printing experiment in space in a newly launched spacecraft, which was put into low-Earth orbit by China's Long March 5B heavylift carrier rocket.
Video broadcast on CCTV showed that the printer has printed a flat section of a honeycomb-shaped (蜂巢状)structure as well as a symbol of China Aerospace Science and Technology Corp, the parent company of the China Academy of Space Technology. The experiment was done by a 3D printer, developed and built by its Beijing Spacecrafts Manufacturing Factory, inside the prototype of China's new — generation manned spacecraft.
The printer, named the Space-Based Composite Material 3D Printing System, uses carbon fiber-reinforced materials to autonomously print objects. It is installed in the reentry module of the experimental spaceship, and will be brought back to Earth once the module returns.
The printer features advanced technologies in material modeling, precision control and automation. Once the space-based 3D printing technology becomes operationally ready, it can extensively benefit space programs as astronauts can use it to manufacture a lot of things they currently need to obtain from resupply flights by cargo spacecraft.
Wang Yanan, editor-in-chief of the Aerospace Knowledge magazine, said the 3D Printer will be very useful in extended space missions, such as those in a space station, because it will allow astronauts to make components quickly and conveniently in space. The technology will save future space journeys considerable resources and costs.
In fact, the device is not the only representative of 3D printing onboard the Prototype.
A CubeSat deployer, designed and made through 3D printing by CoSats Space Technology, is also carried by the spacecraft to check the adaptability of 3D-printed equipment in space.
