The Mir Space Station
The Russian Mir Space Station,which came down in 2001 at last after 15 years of pioneering the concept of long-term human space flight,is remembered for its accomplishments in the human space flight history.It can be credited with many firsts in space.
During Mir's lifetime,Russia spent about US $4.2 billion to build and maintain the station.
The Soviet Union launched Mir,which was designed to last from three to five years,on February 20, 1986,and housed 104 astronauts over 12 years and seven months,most of whom were not Russian.In fact, it became the first international space station by playing host to 162 people from 1 1 countries.From 1995 through 1998,seven astronauts from the United States took turns living on Mir for up to six months each.They were among the 37 Americans who visited the station during nine stopovers by space shuttles.
The more than 400 million the United States provided Russian for the visits not only kept Mir operating,but also gave the Americans and their partners in the international station project valuable experience in long-term flight and multinational operations.
A debate continues over Mir's contributions to science.During its existence,Mir was the laboratory for 23,000 experiments and carried scientific equipment,estimated to be worth $80 million,from many nations.Experiments on Mir are credited with a range of findings,from the first solid measurement of the ration of heavy helium（氦）atoms in space to how to grow wheat in space.But for those favouring human space exploration,Mir showed that people could live and work in space long enough for a trip to Mars.The longest single stay in space is the 437.7 days that Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995.And Sergie Avdeyev accumulated 747.6 days in space in three trips to the space station.The longest American stay was that of Shannon Lucid,who spent 188 days aboard Mir in 1996.
Despite the many firsts Mir accomplished,1997 was a bad year out of 15 for Mir.In 1997,an oxygen generator caught fire.Later,the main computer system broke down,causing the station to drift several times and there were power failures.Most of these problems were repaired,with American help and suppliers,but Mir's reputation as a space station was ruined.
Mir's setbacks are nothing,though,when we compare them with its accomplishments.Mir was a tremendous success,which will be remembered as a milestone in space exploration and the space station that showed long-term human habitation in space was possible.But it's time to move on to the next generation.The International Space Station being built will be better,but it owes a great debt to Mir.

It can be inferred from the last paragraph that______.
A:space exploration will not experience setbacks
B:it is difficult for other space stations to exceed Mir's success
C:Mir is the best long-term human habitation in space in history
D:multinational space operations are getting more accomplishments

The Race Into Space

American millionaire Dennis Tito will always be famous.He was the first tourist in space."I spent sixty
years on Earth and eight days in space and from my viewpoint,it was two separate lives,"Tito explained.He
loxed his time in space."Being in space and looking back at the earth is one of the most rewarding experi-
ences a human being can have."
This kind of experience isn't cheap.It cost$20 million.However,Tito achieved his dream,so he was
happy."For me it was a life dream.It was a dream that began when I didn't have any money,"he
told reporters.
On 24th,April 2002,Mark Shuttleworth became the world's second space tourist.Shuttleworth is a South
African businessman.At the age of twenty-eight,he also paid $20 million for the eight-day trip.
Both Tito and Shuttleworth bought their tickets from a company called Space Adventures.The company
has around 100 people already on their waiting list for flights into space.The spaceship to take them doesn't
exist yet.
Many of the customers are people who like adventure.They are the kind of people who also want to
climb Mount Qomolangma.Other customers are people who love space.However,these people are worried.
Because it's so expensive,only very rich people can go into space.They want space travel to be available to
more people.

That day may soon be here.InterOrbital Systems(IOS)plans to send up to four tourists a week into
space.The tours will depart from an island in Tonga.The company promises a package that includes forty-five
days of astronaut training in Russia and California,seven days in space and a vacation in Tonga,for $2 million.
However,space flight is still very dangerous.Bill Readdy is NASA's deputy assistant administrator for
space flight.He says that the chances of dying are about 1 in 500.Because of this,it may take time before
space tourism really takes off.You might be able to go up,but will you come down?

Mark Shuttleworth is an engineer from the United States.

B:Wrong

Will We Take Vacation in Spaces?
When Mike Kelly first set out to build his own private space-ferry service,he figured his bread-and-butter business would be lofting satellites into high-Earth orbit. Now he thinks he may have figured wrong.“People were always asking me when they could go,”says Kelly,who runs
Kelly Space TechnologT out of San Bernardino,Californi a.“I realized that real market is in space tourism.”
According to preliminary market surveys,there are 10,000 would-be-space-tourists willing to spend $1 million each to visit the final frontier. Space Adventure in Arlington,Virginia,has taken more than 1 30 deposits for a two-hour,$98,000 space tour tentatively(and somewhat dubiously)set to occur by 2005 .Gene Meyers of the Space Island Group says:“Space is the next exotic vacation spot.”
This may all sound great,but there are a few hurdles.Putting a simple satellite into orbit with no oxygen,life support or return trip necessary already costs an astronomical $22,000/kg.
And that doesn't include the cost of insuring rich and possibly litigious passenger. John Pike of the
Federation of American Scientists acerbically suggests that the entire group of entrepreneurs trying to corner the space tourism market have between them“just enough money to blow up one rocket.”The U .S.space agency has plenty of money but zero interest in making space less expensive for the little guys.So the little guys are racing to do what the government has failed to do:design a reusable launch system that's inexpensive,safe and reliable.Kelly Space's prototype looks like a plane that has sprouted rocket engines.Rotary Rocket in Redwood City,California,hasa booster with rotors make a helicopter-style return to Earth;Kistler Aerospace in Kirkland,Wash- ington,is piecing together its versions from old Soviet engines,shuttle-style thermal protection tiles and an elaborate parachute system.The first passenger countdowns are still years away,but bureaucrats at the Federal Aviation Administration in Washington are already informally discussing flight regulations.After all,you can't be too prepared for a trip to that galaxy far,far away.
For those who are intent on joining the 100-mile high club,Hilton and Budget are plotting to build space hotels.Before the Russian space Mir came down,some people were talking about using it as a low-rent space hotel to reduce the cost. If a space hotel is finally built in space,and if you're thinking of staying in it,you may want to check the Michelin ratings before booking yourself a suite.

Kelly hoped to develop space tourism,which he thought would be a good market.
