Please don't be an asshole on HN, even if you don't feel nostalgic for space travel. It helps no one and just makes the thread worse. We've had to ask you this kind of thing before. You've got some good points here, but in the future please express your good points thoughtfully.

If you wouldn't mind reviewing https://news.ycombinator.com/newsguidelines.html and sticking to the rules when posting here, we'd be grateful.
