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.

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.

A teddy bear from Cumbria is launching into space to raise cash for charity(慈善)
Terence,an experienced traveller who has been to Iraq,will be the guest of honour on aviation(飞行)legend Burt Rutan’s Spaceship One when it flies above Earth.The mission takes off from California on September 29, and on his return the loveable toy will be auctioned off(拍卖)in aid of the North AIR Ambulance Appeal(北部空中救护服务中心).
Spaceship One is the world’s first private spacecraft,and is competing for a prestigious space travel prize.Chief executive of the Great North Air Ambulance Service (GNAAS),Graham Pickering,said”flying officer”Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since.
He said,“Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft,trying parachuting and even looking drunk and disorderly.When the RAF finally discharege him he will be a very rare bear indeed‑--we just hope he does not bum up on re‑entry to Earth”.
GNAAS,which needs charitable donations of more than £2m a year,has three air ambulances(空中救护机).
Peter Bond,spokesman for the Royal Astronimical Society,said Terence’s safety was not guaranteed. He said,“This is a new experimental craft and this will only be the second time it has flown.During its first voyage it developed technical problems but hopefully they have now been resolved.”
Since May,Terence has spent time with members of 100 squadron(空军中队)based at RAF Leeming Basra.Iraq,and at air shows with performing fighter planes.
Spaceship One will fly 100km(62 miles) above the Earth’s surface,just breaking through the planet’s atmosphere.

An astronomer is making a case for launching pop singer Justin Bieber into suborbital(亚轨道的)space aboard a private rocket ship. The idea is not to rid the world of the Canadian teenager — he would come back down to Earth eventually, after all — but rather to help jump-start the emerging suborbital spaceflight industry.
It would generate a lot of public interest, which would help commercial spaceflight pick up some much-needed momentum, said Seth Shostak, senior astronomer at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, California. “If there’s more interest, there are more customers. If there are more customers, there's more technical development. It's a positive feedback loop, and obviously that's good.”
Such missions would return to Earth without completing a full lap around the planet. Instead, the flights would hit the edge of space about 62 miles (100 kilometers) above Earth, experience a few minutes of weightlessness, then re-enter the atmosphere and land back at a spaceport.
None of these firms are ready to fly customers yet, but some are getting close. For instance, Virgin Galactic hopes to begin powered test flights of its SpaceShipTwo vehicle later this year, with commercial operations perhaps beginning in 2013 or 2014. It is SpaceShipTwo that reportedly grabbed the attention of Beyonce and Jay-Z.
Virgin Galactic has collected deposits from nearly 500 customers willing to pay $200,000 for a ride aboard SpaceShipTwo, and both Virgin and XCOR have inked deals to fly scientists and their experiments on research flights. So a suborbital market already exists — but Shostak is thinking about ways to make it grow.
A celebrity launch isn't Shostak’s only idea. Suborbital firms should also promote their activities aggressively via social media, Shostak said, and they should make sure their spaceships are bristling(充满)with cameras both inside and out, to give the public dramatic views of every mission.
Some observers view commercial suborbital spaceflight as a potentially transformative industry, saying it could serve as a stepping stone to the exploration and exploitation of space on an unprecedented scale. While the industry’s success is far from assured, Shostak offered some reason for optimism: The American public remains keen on space.
1.Why may Justin Bieber be sent into suborbital space?
A.To show his bravery and make him a role model for teenagers.
B.To arouse the American public’s interest.
C.To help reform the spaceflight industry.
D.To film an advertisement about space.
2.What can we learn about suborbital spaceflight?
A.A trip will return to Earth before finishing a lap.
B.The whole trip will leave passengers weightless.
C.Each trip can take 500 passengers.
D.The trip will be too expensive even for celebrities.
3.What can we infer from the text?
A.SpaceShipTwo will be the first to fly.
B.Famous people will be the main passengers in the future.
C.The space trip is still in preparation.
D.Every space trip will be made into a film.
4.The last paragraph suggests that _________.
A.space is too mysterious to explore
B.the suborbital market is promising
C.the spaceflight industry is more successful than people think
D.developing the industry is risky
5.What is the main purpose of the text?
A.To predict a change in the space market.
B.To discuss a recent launch.
C.To introduce the status of the spaceflight industry.
D.To remove public doubt about the spaceflight industry.

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

Before astronauts can go into space, they have to have the right suit. That’s why NASA(美国国家航天和航空局)scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(灵活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.
Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
1. What characteristic does the new space suit have?
A. The new space suit will need much maintenance.
B. The new space suit will be heavier than before.
C. The new space suit will have less mobility than before.
D. The new suit will use new technology to help astronauts be safe in outer space.
2.What’s the disadvantage of the Russian space suit?
A. The Russian space suit is big and massive.
B. The Russian space suit is much complicated.
C. The Russian space suit is merely used a few times.
D. The Russian space suit is easy to work in for long periods of time.
3.The underlined word “shield” in the third paragraph might mean_______.
A. harm B. protect C. help D. warn
4.Why can scientists test the design out before actually making the new space suits?
A. Because designing the new space suit is not a complex task.
B. Because computers are being used to help scientists design the new space suits.
C. Because it needs little knowledge to design the new space suits.
D. Because the scientists only change the old space suits a little and make them into the new ones.
5.How long will it take scientists to put the new space suits from prototypes into the first practical use?
A. Two years. B. Three years. C. Four years. D. Six years.
