Because the first day of the new year starts just after midnight. That's why countries all round the world celebrate new year at different instances.

Even if this were actually said, Apollo 13 was a failure as a mission.

Everyone got back safely, but the contractor who built the cryo tanks dropped the tank, tried to burn off the fuel overnight, unknowingly and accidentally exposed the wiring inside the tank to temperatures that far exceeded the design temperatures, which burned off the protective wire insulation.

That would (months later) result in the liquid oxygen in the tanks being ignited by a spark from the wire.

That was a procedural failure that lead to a moon-landing mission failure.

The point is, failures happen and always will continue to happen -- whether your program wants them to or not.

Honestly think that we’re a little too cautious when it comes to space and that’s inhibited us going back to the moon for like 50 years. Shit is gonna go wrong. People will probably die. Everyone sitting on top of a rocket knows they’re in danger.

We’re not going to colonize the solar system without deaths. I like to think the colonization of space is similar to the colonization of the Americas. (Which is an entirely different conversation I know) but the people on those boats knew their chances of death was high, they knew they were never going back to England or wherever, they went anyway. We have to get some of that mindset back if we’re going to Mars and the moon etc.

This isn't true. I've worked with a lot of motherfuckers that haven't done anything. They never fail, you have to at least try to fail. Their management failed though, by hiring and keeping them there as long as they did. Usually they corrected that failure by firing them.

That doesn't mean that we need to compromise safety for expediency or a mission statement. Astronauts accept the risk, but negligence due to some suit saying that you can't fail isn't acceptable levels of risk. In fact, it's external stressors (such as unreasonable expectations) that can directly lead to more mistakes than otherwise would be noted. Sacrificing safety for expediency.

Failure is an option if the costs are in dollars and the risk/reward ratio makes sense. Cheap cubesat demonstrators, for example, are usually more valuable done quickly rather than made 800% bulletproof.

When lives or billion-dollar missions are at stake, that's when failure isnt an option.
