It wasn't a lot—just a tiny, unexplained deceleration towards the Sun. But in the precise world of orbital mechanics, it was huge. The probes were thousands of miles away from where the math said they should be. This became known as the Pioneer Anomaly. For 30 years, this mystery baffled scientists. Was it an invisible cloud of Dark Matter slowing them down? Was our understanding of gravity wrong? Was it a glitch in General Relativity? It turned out to be something much simpler, but incredible t
