Space is hard. You’re strapping something inside a big tube with basically directed explosives at the bottom, hoping it survives the trip, then subjecting it to constant radiation, huge temperature swings, and other brutal environmental factors like micrometeoroids. Just because we’ve been sending satellites and people up to space for nearly 70 years doesn’t mean it’s gotten easier; we’re just better at knowing what to expect so we can test for it. Failures in rockets or satellites or even manned spacecraft are going to happen as much as we work to prevent them.
