well it's a good cover for nearly $2.5 billion.
In all Honesty, I do like we are exploring Space & Am hoping Something shows up
to prove once & for all there was Life on Mars & That NASA Admits it.
You hit on perhaps the main reason for space exploration. Remember when the first Russians went into space they joked about not seeing God or any angels?
While there are many reasons for space exploration one aspect stands out AT THIS TIME. That is the need to discover life outside earth so that this information (along with evolution) may be used in our schools to strengthen the cause of undermining all religions. Religion today (all religions) is seen as repressive and ignorant by the majority of the most elite educators. It is considered very much counterproductive to the advancement of mankind. An ever growing majority of the world's most intellectually advanced scientists, etc., have as ONE OF THEIR GOALS in life the total extermination of religion.
Religion stands in the way of countless future advancements (according to them). For one, it is religion (or spin-offs of it) that blocks the elimination of people viewed as leaches of society (the welfare crowd, mentally ill, elderly, etc.). As mentioned above by another poster, many would like to see all or almost all "entitlement" types of wasteful spending eliminated, but religion (and it's influence) stands in the way (and also non-religious silly emotionalism which is a spin-off of religion).
In a way this is what was behind Hitler's philosophy. The Christian view that ALL life is precious and must be preserved stood directly in his way. This is why in all communist countries serious Christianity is hated and even as I write this Christians are being killed and incarcerated for their faith.
In fact the main reason for evolution was to undermine the concept that life is precious. This is how we got abortion.
So, expect to read of many forthcoming "undeniable proofs" that life existed on other planets. Because, as stated, this right now is one of the main reasons for the entire space program.
