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 USS 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 whorh were not Russian. In fact, it
became the first international space station by playing host to 62 people from
11 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 carded 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 atoms in space to how to grow wheat in space. But for those favoring
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 mined. 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 long4erm 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. The writer tends to think that Mir was ______. A. everything
