National Aeronautics and Space Administration - the successor of the earlier National Advisory Committee for Aeronautics. Begun in 1958, largely in order to gain a moral victory in the Cold War by beating the USSR to the moon, their main purpose is to gain knowledge about outer space and neighboring celestial objects in order to increase humanity's knowledge of the cosmos. Initially well-funded and manned by some of the greatest scientists of the 20th century, the Administration's space programs helped to develop some of the most influential and often-used technology of the modern day (satellite technology, computers, electronic miniaturization, temperature resistant materials, etc.). Unfortunately, due to the multitude of early successes and prevailing opinion in Washington, NASA is often expected to do more with less money, as Congress often slashes budgets and expects better service. Not wanting to lose the tradition of innovation, NASA has recently tried to appease the government and an ever-increasing public ignorance of the benefits of scientific exploration, and as a result has tried to do more than they should, resulting in the 1986 Challenger explosion, and the heat shield failure of the Columbia in 2003, along with less deadly failures of Mars probes.
NASA fails because we allow it to; we expect that becuase "those NASA guys are geniuses" that they can do something with next to nothing. Space travel has always been, and will always be dangerous.

NASA - representing "Nice And Safe Attitude"
Used as a salutation, or farewell –an interjection
Popularised by a clothing brand worn by some in the late 1990's UK rave scene.
At first glance, the garment would appear to be an official National Aeronautics and Space Administration or NASA product, as the logo used the worm font used by NASA. However beneath the main NASA text body, it would state "Nice And Safe Attitude".
Person A "see you round mate"
person B "yeah, you too, nasa"

Person A "Hiya mate, nasa"
Person B "Yeah, wicked"

Interestingly many of those that wore this product line did not have a nice and safe attitude at all. They were in fact drug addled party kids that had taken too many class A drugs, and as a result had become paranoid, violent or simply talked a load of bollocks at such a high speed they spat in your face as they attempted to purge their body of words.
As a result the greeting is used in a rather tongue in cheek fashion today.

The really cool guys that the government gives a whole lotta cash for them to do stuff in space!
Competitors: The Russian Federal Space Agency (RFSA)
Justification: The Earth will eventually die, and when that happens we gotta do sometin'!...
When NASA first started sending up astronauts, they quickly
discovered that ball-point pens would not work in zero gravity. To combat this problem, NASA scientists spent a decade and $12 billion developing a pen that writes in zero gravity, upside-down, on almost any surface including glass and
at temperatures ranging from below freezing to over 300 C.
The Russians used a pencil. Your taxes are due again–enjoy paying them!
