The “Atlantis” was the first since 1985, serving 32 flights, is also planned last. “Discovery” and “Endeavour” was will be held in September and November for the last flight. By then, the three space shuttle missions will be a total of 134 records of all retired, declaring the U.S. “space shuttle era” end.

    Development of the space shuttle .
Main aim is to use its reusable space shuttles to reduce the cost, both as a means of transport, but also the same as the aircraft in orbit around the Earth, returned to Earth after launch to use again after repairs. It was originally proposed design of the space shuttle, because it is both launch vehicles, manned spacecraft, and repeated .
Use can still maintain high-performance features, this, in addition to the United States, the former Soviet Union, France and the United Kingdom and so had exploration of the space shuttle program has done research work, but ultimately only the United States developed a practical space shuttle.
    But the shuttle has failed to prove whether the province where they were. On .

And the need is not great.
    U.S. “space shuttle era,” does not indicate the end of the decline of U.S. space forces, but the decline in the overall strength of the United States to become more pragmatic, the United States live in space have begun to plan carefully. Obama is more willing to Government under a limited budget, will .
Be landing on Mars as the focus of future U.S. space industry.
    NASA space missions and space shuttle program director  Meyer leader John Shannon sighs: “No other spacecraft to complete the International Space Station’s construction and assembly tasks. Now about to assemble the International Space Station is co mpleted, it is time for space shuttle retired. “” I am looking .
Forward to it does not bring the sad end of an era, but we have participated in the joy of this era. there is no space shuttle, international space station can not be completed. This will be the history of mankind’s greatest works

This caused the U.S. industry’s discontent. Some media wrote that the United States in future lunar exploration program and plans to reduce funding for space exploration, will the loss of U.S. space exploration initiative. The space shuttle’s retirement deepened the concerns of people on this issue, some experts question bluntly that “the shuttle retired, the United States could be left?” .
    However, some people of the United States currently plans to reduce funding for space exploration, decision support. Media reports, the National Aeronautics and Space Administration for the construction of the International Space Station more than 400 billion dollars invested, plus the huge post-maintenance costs, it is a great investment. However, such a large investment, and compared to the international .
Space station even though it engaged in research projects, joint development of human space and education, made great contributions, but the actual results of the International Space Station are of view, is clearly “make ends meet.” In the United States is as high as 1.6 trillion dollar budget deficit situation, continue to uphold the international space station, space shuttle flight .

The U.S. decided to abandon the “shuttle” project.
    November this year, “Endeavour” was the last time on behalf of fly space shuttle, for nearly 30 years of shuttle flight history to an end. All three space shuttles in the United States, retired, the international space station maintenance work by the Russian and other international partners, or private manned spacecraft .
To complete. The U.S. has already begun with the Russian consultations on transportation issues. But scientists pointed out that no country can be like the space shuttle spacecraft as a large space to carry a lot of work to complete, so the shuttle’s retirement, will continue to run on to the international space station in 2020 is undoubtedly a huge .
Loss.
    U.S. President Barack Obama in February of this year submitted to Congress the government fiscal year 2011 budget, the proposed return to the moon space shuttle retirement and cancellation of the “Constellation” program and “God of War” rocket program, the U.S. commercial rocket in 2016 may be put into operation will be lost before the manned launch capability. .

Manned space flight life support system similar. Blue from the company’s money will be used in a sealed module and launch escape system research and development.
    For commercial companies to enter the space program is a huge business opportunity.
    U.S. Space Adventures cooperation with the Russian Space Agency, since 2001, launched the “Space Travel” people have been enjoying .
This service since. Price from the beginning of the 20 million U.S. dollars soared to 35 million U.S. dollars. U.S. estimated XCOR Aerospace, the current potential of private space travel market more than 500,000,000 U.S. dollars, is a mouth-watering cake.
    Commercial companies to enter the realm of space seems to have “unstoppable.”

Years ago, the U.S. astronaut  success of Lance Armstrong on the moon. 41 years later, we have to accept the fact – Human beings are still wandering around the earth. Put into use after the shuttle has not achieved its original intended purposes. So in 2010, scientists from 16 countries participate in the basic completion of the international space station, .

    In addition to providing more funding for space science, the new budget will also finance commercial manned space flight. Because NASA had to face the reality that all the shuttle retired, the United States will lose the astronauts into Earth orbit or from the international space station capabilities.
    According to Russian media had reported that from 2012, .
Russia will go to the International Space Station, astronauts receive 51 million U.S. dollars per person a “toll.” In 2006, Russia to fly to the International Space Station astronauts each charged by the United States 21.8 million U.S. dollars.
    Therefore, the new proposed budget from the government to the private sector together to develop new rockets and manned space .
Vehicle. After Obama announced in the Budget, NASA announced that the five commercial companies to provide a total of 50 million U.S. dollars of capital to do R & D start-up capital, which will also create about 5,000 new jobs.
    And NASA signed the “space operation agreement” companies: Sierra Nevada Corporation (20 million U.S. dollars), Boeing (18 million U.S. .

Dollars to develop new carbon-monitoring satellites, the new satellite is expected to be in February 2013 prior to launch. In fact, in the “track carbon observatory” a few days after the launch failure, NASA began a replacement program of research, hoping to be able to fill in 28 months on this vacancy.
    Expedition outside the solar system in order .
To power the robot, the White House instructed NASA and the Department of Energy to start manufacturing plutonium -238, while the U.S. 20 years ago, the laboratory has been discontinued in the event. U.S. Department of Energy laboratory originally imported from Russia’s atomic plutonium -238, but U.S. and Russian future demand for outer planet exploration robot makes plutonium -238 reserves .
Become overstretched. NASA plans to launch for the 2020 Europa “flagship” detectors require large amounts of plutonium to provide energy. Meanwhile, NASA will also develop new Stirling radioisotope generator. This is a more efficient energy system that can reduce the consumption of scarce plutonium.
    Obviously, Obama focus more on the Budget of the effectiveness of space research.

Rocket separation, parachute system is not fully opened.
    This funding has been too huge and “lackluster,” the soft underbelly of the plan. President George W. Bush was the first promise of 5 years and 7% of the budget growth is a bad check. Since the “Constellation” program from the date of birth, have the final say in the U.S. .
