When it comes to space, failure isn't just an option — it's a requirement

That’s pretty much how everything we do works. If it breaks, fix it or build a new one, but make it better. We learn from mistakes and stuff that didn’t work right. We walk better at 14 years of age than 14 months. 30 year olds drive better than 16 year olds (the 16 year old would disagree). Cars, airplanes, buildings, even hand tools work better today than before due to better design after previous ones broke.
Most U.S. OSHA regulations are the results of accidents, not because they foresaw a problem.
