When Christopher Columbus set out, he was hoping to find a way to
india by going west. He didn't find what he was looking for. But he
found something totally unexpected.
Mankind is compelled to explore. From a kid wanting to take things
apart to see what is inside, or adults wanting to see new lands and
explore, it is a built-in need.
Going to other planets and possibly finding other life forms is not an
economic activity, it is a humankind activity. It is money spent to
make us feel good, give us a feeling that mankind is evolving
positively and possibly might find something terribly exciting. And
even if we don't going to mars and coming back will be quite the
accomplishement.
Humans need challenges. Whether it is climbing everest, cycling across
australia or going to mars, it is a challenge.
Going to mars is a difficult challenge because we don't quite yet have
the technology to go there and must develop and test it. The space
station is one such test. In and by itself, the station isn't going to
yield any fanstastic discoveries, but it will teach us how to build a
long term vehicle, how to live in such etc etc. If your goal is to
climb everest, you will likely start by climbing smaller mountains to
test your equipment and know yoru capabilities.
Apollo (and the CEV/Constallation) will just be weekend camping trips
to the Moon. Humankind has been there, done that. Nothing new.
But building a vehicle that can go to mars and back with a large crew,
as well as the vehicles to land on mars and get back to the main ship
remains a formidable challenge.
the space station is also baby steps in learning to work together so
that different countries could contribute to a trip to mars. So such a
trip, instead of being a immature competition on who can get to te
moon first, will be a truly human endeavour encompassing the planet.
Instead of building new shuttles, the USA has chosen to build appolo
vehicles and some cargo rockets, and hopefully will also develop
automated docking capabilities which the USA has not needed due to the
shuttle's abilities. Once the shuttle's abilities have been fully
replaced (or new shuttles built once constellation is cancelled), then
the USA can resume its progress in building large structures in space
that would be capable of eventually going to mars and back.
Is there anything in this post that adresses the question?
