NASA’s most expensive mistake

How much damage can a missing punctuation mark do? In NASA's case, about $5 billion worth. It's 1962. NASA launches Mariner 1, America's first space probe, to another planet. Its mission, a groundbreaking flyby of Venus. But shortly after launch. Houston, we have a problem. The rocket goes haywire. And to avoid crashing back to Earth, NASA blew up Mariner one in the middle of space. But why? You won't believe this. It all came down to a single missing hyphen in the guidance software. One tiny typo led to a $5 billion failure. It might just be the most expensive hyphen in history, but there is some good news. This mistake sparked a revolution in code review processes, not just at NASA, but across the entire tech industry. Today, as we build AI self driving cars and medical software, this lesson is more relevant than ever. So remember, details matter. A lot.
