In my humble opinion, the moon landing was an important mission and amazing achievement especially for the United States during a very tumultuous time.
Sward, for me personally... I'm a HUGE fan of the launch of The Hubble space telescope. When I consider all the images and overall understanding of the universe that we have gotten from that amazing, amazing telescope, I can't help but be in awe at the end product of all that work.
I'm just not sure if that would be considered a "mission"... What I AM sure of, is that there are also a lot of missions I am unaware of.. So my counter question would be:
What would be yours, or, anyone else's most important mission of choice?
Speaking of Hubble, I had a picture come across my desk that I believe taken by Hubble. and found it very beautiful and fascinating. All it said was "Heartbeat of the crab nebula". Has anyone else seen this photo and have we figured out what that energy wave-" heart beat" actually is?
sward et al. My opinion, it was in the movie October Skies. 1957 Russian Sputnik orbit. That *panicked* the USA into action and shortly after, Mercury program with John Glenn. I grew up watching X-15, Mercury, Gemini, and Apollo programs so I am a bit older now
