It isn't Easy Being Green and Getting to LEO
MWTJ writes "The BBC has a story about the environmental impact of the space shuttle. One of the things that started the modern environmentalist movement were pictures of the Earth from space, so we could see the beauty of the planet as never before. We could also see environmental destruction from space. But what is the impact of the space program on our planet? The story talks about the switch to Freon-free insulation, the use of clean-burning hydrogen/LOX fuel, and other factors. What else could be done to get to space with minimal harm to the planet?"
Maybe if they used CFC-based insulation that was stronger, like they used to, they'd have fewer explosions therefore less polutants entering the atmosphere and fewer dead astronauts? Just my vote.
While the effort is admirable, getting too bent out of shape over the space shuttle's emissions is a little myopic. Weighed against all of the benefits and advancements we've gleaned from the space program, I'd say the environmental impact is pretty negligible. The article itself suggests that the damage to wildlife from hydrochloric acid deposits is "minimal and manageable".
I can't imagine that the costs of upgrading a $1.7 billion shuttle to make NASA's once-in-a-blue-moon launches more earth-friendly will be reasonable for taxpayers. Environmentalists looking for something to complain about should have no trouble finding a better outlet for their ire in corporate America than at NASA.
domain combinatorics
Put this in perspective, people. There are TWO space shuttles still in service, and even though they have a CFC exemption, and it was the breaking off of a piece of that insulation that caused the Colombia disaster, they STILL use non-fluorocarbon (non-freon based) foam for insulation on the shuttles.
As stated in the comments to the article on the bottom of the page, underground fires and about a bazillion other natural sources have more of an environmental impact than the shuttle. If anything, industries and the world's large polluters ought to learn from the efficiency of NASA wiht regard to abusing/respecting the environment.
and then as has happened in other fields - Western bleeding hearts set out to save the world via job-killing regulations at home, and then other countries (who could give a rat's ass about the environment) eat our lunch with cheaper products/services, ala China.
The path to hell is paved with good intentions..
Your hybrid is not saving the environment. Its purpose is to make you feel good about buying something.
