It's a sad thing, but remember there are deaths by accident everywhere around the world, most a lot worse, and these people knew the risks. I know this sounds heartless - but it's not, really. They'll go down in history as heroes who lost their lives for their country and for humanity. I wish I could go that way.
What's perhaps worse than the deaths of seven good people is the damage done to the space program, and to mankind's conquest of space. This is likely to set it back years, if not decades, and that's not how I would like to celebrate the bravery of seven astronauts.
People sometimes die when they try to aspire to greater things, but if we gave them up because of that we might as well go back to the trees.
