Nasa at 50, looking for second wind...
NASA loves to try and push ideas at people. Often times, the pictures and information beamed back to Earth are so astonishing and filled with raw excitement that it almost does not matter how things are presented. More often than not, the relevance is not apparent and some additional pushing needs to be done. Alas, that pushing does not always work. Also, there is more to space exploration - and its relevance - than pretty pictures or complicated intellectual discussions.
