Fortunately, lunar-orbit rendezvous required two separate vehicles with independent power, life-support, and computer systems. That redundancy saved 13 when one of the vehicles was damaged.
What the article didn’t expand on was WHY it happened - the first few Apollo Service Modules all had (IIRC) 24-volt electrical systems. But somewhere mid-program NASA changed the spec to 36V, and that change - for whatever reason - wasn’t passed on to the people who designed the heater systems for the frozen gas tanks. So when the new, higher voltage was applied to warm the liquid oxygen, it heated up a lot more than was calculated, and the predictable result occurred - an explosion.
Yes, and the heaters were required to keep the oxygen from freezing solid.
“...and that change - for whatever reason - wasn’t passed on to the people who designed the heater systems...”
A lot, maybe most of the problems I come across is due to a lack of communication. And communicating BEFORE the first nail is driven, hole is dug, or... well I won’t go there.
It is a REALLY big issue for any endeavor.
