The article linked below succinctly sums up the era of the space shuttle. Richard Velotta intertwines a little family humor with some sad facts about the last flight of Atlantis.
At 64, I hesitate to imagine that an era of 30 years has passed. I vividly recall - even the moon walk, the rockets, the ocean landings with the astronauts bobbing around in the bumpy seas. Where has all this time gone...
But, as Mr. Velotta suggests, sometimes a closed door opens another - maybe different, but usually better. Better...may entail asteroids, other planets...and maybe in another lifetime, another universe.
As always, Nature prevails - even in Space!
