What Does NASA Do?



In one sense, it's very simple:

NASA explores.
NASA discovers.
NASA seeks to understand.

To do that, thousands of people have been working around the world -- and off of it -- for more than 45 years, trying to answer some basic questions. What's out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?

A Little History

President Dwight D. Eisenhower established the National Aeronautics and Space Administration in 1958, partially in response to the Soviet Union's launch of the first artificial satellite. NASA grew out of the National Advisory Committee on Aeronautics, which had been researching flight technology for more than 40 years.

President John F. Kennedy focused NASA and the nation on sending astronauts to the moon by the end of the 1960s. Through the Mercury and Gemini projects, NASA developed the technology and skills it needed for the journey. On July 20, 1969, Neil Armstrong and Buzz Aldrin became the first of 12 men to walk on the moon, meeting Kennedy's challenge.

In the meantime, NASA was continuing the aeronautics research pioneered by NACA. It also conducted purely scientific research and worked on developing applications for space technology, combining both pursuits in developing the first weather and communications satellites.

After Apollo, NASA focused on developing America's ready access to space: the space shuttle. First launched in 1981, the Space Shuttle has had 112 successful flights, though two crews have been lost. In 2000, the United States and Russia established permanent human presence in space aboard the international space station, a multinational project representing the work of 16 nations.

NASA has also continued its scientific research. In 1997, Mars Pathfinder became the first in a fleet of spacecraft that will explore Mars in the next decade, as we try to determine if life ever existed there. The Terra and Aqua satellites are flagships of a different fleet, this one in Earth orbit, which is designed to help us understand how our home world changes. NASA's aeronautics teams are focused on improved aircraft travel and making it safer and less polluting.

Throughout its history, NASA has conducted or funded research that has led to numerous improvements to life here on Earth.

Organization

NASA Headquarters, in Washington, provides overall guidance and direction to the Agency, under the leadership of Administrator Michael Griffin. Ten field centers and a variety of installations conduct the day-to-day work, in laboratories, on air fields, in wind tunnels and in control rooms. NASA Today NASA conducts its work in four principle organizations, called mission directorates: Aeronautics: pioneering and proving new flight technologies that improve our ability to explore and which have practical applications on Earth. Exploration Systems: creating new capabilities for affordable, sustainable human and robotic exploration

Science: exploring the Earth, moon, Mars and beyond; charting the best route of discovery; and reaping the benefits of Earth and space exploration for society.

Space Operations: providing critical enabling technologies for much of the rest of NASA through the space shuttle, the international space station and flight support.

In 2005, NASA's reach spans the universe. Spirit and Opportunity, the Mars Exploration Rovers, are still going on Mars after more than a year. Cassini is in orbit around Saturn. The Hubble Space Telescope continues to explore the deepest reaches of the cosmos.

Closer to home, the latest crew of the international space station is extending the permanent human presence in space. Earth Science satellites are sending back unprecedented data on Earth's oceans, climate and other features. NASA's aeronautics team is working with other government organizations, universities, and industry to fundamentally improve the air transportation experience and retain our nation's leadership in global aviation. And, most importantly, NASA has begun returning the space shuttle to flight. Led by Commander Eileen Collins, the crew of Discovery tested new in-flight safety procedures and carried supplies to the international space station.
