we watched some of our DVR backlog this morning with brunch. since seeing the first in the series, i have been enthralled with Discovery Channel’s When We Left Earth. i’m not generally a heart-on-my-sleeve kind of guy, but i tend to get emotional watching these shows.
i think it’s something about the enormity of the challenge, and the grace at which the astronauts accept it. the rewards of success, are to leave a legacy of advancing every aspect of human endeavor. the risks, you might think, would be death alone. but the risk of failure for early NASA missions went far beyond that.
there were no people, in any profession, in any place, who were not touched, inspired, motivated, lifted, by the trials and triumphs of our journey into space.
Instead of saying ‘You Americans did it’, everywhere they said ‘We did it – we, humankind.’ I’d never heard people in different countries use this word ‘we, we, we’ as emphaticallyâ€¦ I thought that was a wonderful thing. Ephemeral, but wonderful.

the episode i watched today was about the earlier missions, Project Mercury. a quote from President John F. Kennedy really struck me. this was in reference to John Glenn’s first orbital flight in 1962:
We have a long way to go in this space race. But this is the new ocean, and I believe the United States must sail on it and be in a position second to none.
John F. Kennedy 
this is the new ocean. where the explorers who sailed from shores in europe to seek new lands, gazed out at the ocean as the last, vast, limitless unknown challenge for humanityâ€”we came to know it, chart it, analyze it, conquer it. modern forms of travel make the ocean almost trivial.
will we someday ‘conquer’ space? i don’t think so. at least i hope not. whereas the oceans can be quantified in a scale that humans can (at our greatest abstraction) comprehend; space is vast in a way that we may never truly understand.
and i like it that way. when there is always something beyond our reach, when there is forever a goal that is scarcely not attainable, is when we are at our most clever, our most inspired, our most alive. we need to relish what we are doing in this pursuit, as this is where we play out our lives and write our own stories; the future may retell these as the beginning of something wondrous.
