Currently, the ISS relies on the Shuttle fleet for all major construction shipments. Despite the reduction of its budget following project Apollo, NASA has maintained a top-heavy bureaucracy resulting in inflated costs and compromised hardware. Government proposed eventually replacing the Shuttle with a Crew Exploration Vehicle that would allow the agency to again send astronauts to the Moon. In 2004 the U.S.

The Apollo spacecraft and Saturn family of launch vehicles were abandoned in 1970 after billions of dollars had been spent on their development. Some commentators, such as Mark Wade, note that NASA has suffered from a 'stop-start' approach to its human spaceflight programs. The Challenges include tasks that will be useful for implementing the Vision for Space Exploration, such as building more efficient astronaut gloves. Hoping to spur innovation from the private sector, NASA established a series of Centennial Challenges, technology prizes for non-government teams, in 2004.

Although the plan initially met with skepticism from Congress, in late 2004 Congress agreed to provide start-up funds for the first year's worth of the new space vision. The future of the ISS is somewhat uncertain – construction will be completed, but beyond that is less clear. The space shuttle will be retired in 2010 and the Crew Exploration Vehicle will replace it by 2014, capable of both docking with the ISS and leaving the Earth's orbit. According to this plan, humankind will return to the moon by 2020, and set up outposts as a testbed and potential resource for future missions.

Bush announced a new plan for NASA's future, dubbed the Vision for Space Exploration. On January 14, 2004, ten days after the landing of Mars Exploration Rover Spirit, President George W. government, various scientists, and the public all considered the future of the space program. The U.S.

The Space Shuttle Columbia disaster in 2003, which killed the crew of six American and one Israeli astronaut, and caused a 29-month hiatus in space shuttle flights, triggered a serious re-examination of NASA's priorities. NASA expects to continue exploring the Red Planet with more spacecraft such as the Mars Reconnaissance Orbiter, which will reach Mars in 2006. Since 2001, the orbiting Mars Odyssey has been searching for evidence of past or present water and volcanic activity on the red planet. Less publicly acclaimed but performing science from 1997 to date (2005) has been the Mars Global Surveyor orbiter.

Newspapers around the world carried images of the lander dispatching its own rover, Sojourner, to explore the surface of Mars in a way never done before at any extra-terrestrial location. NASA's most publicly-inspiring mission of recent years has probably been the Mars Pathfinder mission of 1997. With over 112 successful launches, NASA's shuttle program is arguably the best manned space program to date. That method was criticized and re-evaluated following the twin losses of Mars Climate Orbiter and Mars Polar Lander in 1999.

Goldin, pioneered the "faster, better, cheaper" approach that enabled NASA to cut costs while still delivering a wide variety of aerospace programs (Discovery Program). In response, NASA's ninth administrator, Daniel S. During much of the 1990s, NASA was faced with shrinking annual budgets due to Congressional belt-tightening in Washington, DC. Even now, the ISS cannot accommodate as many scientists as planned.

The population at large have historically been hard to impress with details of scientific experiments in space, preferring news of grand projects to exotic locations. Costing over one hundred billion dollars, it has been difficult at times for NASA to justify the ISS. The strength of their cooperation on this project was even more evident when NASA began relying on Russian launch vehicles to service the ISS following the 2003 Columbia disaster, which grounded the shuttle fleet for well over two years. This cooperation continues to the present day, with Russia and America the two biggest partners in the largest space station ever built – the International Space Station (ISS).

In 1995 Russian-American interaction would again be achieved as the Shuttle-Mir missions began, and once more a Russian craft (this time a full-fledged space station) docked with an American vehicle. The HST is a joint project between ESA and NASA, and its success has paved the way for greater collaboration between the agencies. Some of the images it has returned have become near-legendary, such as the groundbreaking Hubble Deep Field images. The HST was created with a relatively small budget of $2 billion but has continued operation since 1990 and has delighted both scientists and the public.

Nonetheless, the shuttle has been used to launch milestone projects like the Hubble Space Telescope (HST). The Challenger disaster aside the late 1980s marked a low point for NASA. Work began on Space Station Freedom as a focus for the manned space programme but within NASA there was argument that these projects came at the expense of more inspiring unmanned missions such as the Voyager probes. The shuttle was not all good news for NASA – flights were much more expensive than initially projected, and even after the 1986 Challenger disaster highlighted the risks of space flight, the public again lost interest as missions appeared to become mundane.

The first to launch, Columbia did so on April 12, 1981. Planned to be a frequently launchable and mostly reusable vehicle, four space shuttles were built by 1985. The space shuttle became the major focus of NASA in the late 1970s and the 1980s. America's first space station, Skylab, occupied NASA from the end of Apollo until the late 1970s.

Although the Cold War would last many more years, this was a critical point in NASA's history and much of the international co-operation in space exploration that exists today has its genesis with this mission. On July 17, 1975 an Apollo craft (finding a new use after the cancelling of planned lunar flights) was docked to the Soviet Soyuz 19 spacecraft, in the Apollo-Soyuz Test Project. Having lost the moon race, the Soviet Union had, along with the USA, changed its approach. Later, the two Viking probes landed on the surface of Mars and sent color images back to Earth, but perhaps more impressive were the Pioneer and particularly Voyager missions that visited Jupiter, Saturn, Uranus and Neptune sending back scientific information and color images.

The Ranger, Surveyor, and Lunar Orbiter missions were essential to assessing lunar conditions before attempting Apollo landings with humans on board. In 1962 the Mariner 2 mission was launched and became the first spacecraft to make a flyby of another planet – in this case Venus. Although the vast majority of NASA's budget has been spent on human spaceflight, there have been many robotic missions instigated by the space agency. The program ended because of budget cuts (in part due to the Vietnam War) and the desire to develop a reusable space vehicle.

Although missions up to Apollo 20 were planned, Apollo 17 was the last mission to fly under the Apollo banner. The near-disaster of Apollo 13, where an oxygen tank explosion nearly doomed all three astronauts, helped to recapture national attention and concern. Plans for ambitious follow-on projects to construct a space station, establish a lunar base and launch a human mission to Mars by 1990 were proposed but with the end to procurement of Saturn and Apollo hardware, there was no capability to support these. After President Lyndon Johnson left office, NASA lost its main political supporter, and rocket scientist Wernher von Braun was moved to a position lobbying in Washington.

NASA had won the moon race, and in some senses this left it without direction, or at the very least without the public attention and interest that was necessary to guarantee large budgets from Congress. Twelve men would set foot on the Moon by the end of the Apollo program in December 1972. Armstrong's first words upon stepping out of the Eagle lander captured the momentousness of the occasion: "That's one small step for [a] man, one giant leap for mankind". After eight years of preliminary missions, including NASA's first loss of astronauts with the Apollo 1 launch pad fire, and the first spacecraft to orbit the Moon (Apollo 8) at the end of 1968, the Apollo program achieved its goals with Apollo 11 which landed Neil Armstrong and Buzz Aldrin on the moon's surface on July 20, 1969 and returned them to Earth safely on July 24.

The Gemini program was started shortly thereafter to provide an interim spacecraft to prove techniques needed for the now much more complicated Apollo missions. Thus Apollo became a program to land men on the Moon. Kennedy's announcement on May 25, 1961 that the United States should commit itself to "landing a man on the Moon and returning him safely to the Earth" by 1970. The direction of the Apollo program was radically altered following President John F.

Following the success of the Mercury and Gemini programs, the Apollo program was launched to try to do interesting work in space and possibly put men around (but not on) the Moon. Nine other missions followed, showing that long-duration human space flight was possible, proving that rendezvous and docking with another vehicle in space was possible, and gathering medical data on the effects of weightlessness on humans. Young on March 23, 1965. The first Gemini flight with astronauts on board, Gemini III, was flown by Virgil "Gus" Grissom and John W.

Once the Mercury project proved that human spaceflight was possible, project Gemini was launched to conduct experiments and work out issues relating to a moon mission. John Glenn became the first American to orbit the Earth on February 20, 1962 during the 5-hour flight of Friendship 7. became the first American in space when he piloted Freedom 7 on a 15-minute suborbital flight.

NASA's early programs were research into human spaceflight, and were conducted under the pressure of the competition between the USA and the USSR (the Space Race) that existed during the Cold War. Elements of the Army Ballistic Missile Agency (of which von Braun's team was a part) and the Naval Research Laboratory were incorporated into NASA. When it began operations on October 1, 1958, NASA consisted mainly of the four laboratories and some 8,000 employees of the government's 46-year-old research agency for aeronautics, the National Advisory Committee for Aeronautics (NACA), though the probably most important contribution actually had its roots in the German rocket program led by Wernher von Braun, who is today regarded as the father of the United States space program. On July 29, 1958, President Eisenhower signed the National Aeronautics and Space Act establishing the National Aeronautics and Space Administration (NASA).

Several months of debate produced agreement that a new federal agency was needed to conduct all nonmilitary activity in space. Eisenhower and his advisers counseled more deliberate measures. security and technological leadership (known as "Sputnik Shock"), urged immediate and swift action; President Dwight D. Congress, alarmed by the perceived threat to U.S.

The U.S. Following the Soviet space program's launch of the world's first man-made satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. Its mission is "to understand and protect our home planet; to explore the Universe and search for life; and to inspire the next generation of explorers". NASA's vision is "to improve life here, extend life to there, and to find life beyond".
