35th Anniversary of Apollo 13 Splashdown

orac2 writes "35 years ago today, the crew of the Apollo 13 mission splashed down in the Pacific, after a harrowing four days following an oxygen tank explosion aboard their spacecraft. If you've only seen the Ron Howard movie, IEEE Spectrum has an article about what really went on in mission control to save the crew, with interviews with Gene Kranz, etc,and including a previously unreported hack the lunar module controllers had to come up with in real-time just to turn on the LM."

will we have to see this article every 5 years

Perhaps, but sadly unlikely because the Apollo mission controllers are beginning to pass away at an increasing rate. At lot of them are still in good health, but Sy Liebergot has a list of deceased controllers in his 2003 autobiography, Apollo EECOM that's a page long, and he's said recently that if he released a second edition he'd have to add another bunch of names already: for example, Don Puddy, who played a key role in the post Apollo-10 sim lifeboat procedures team, passed away last November.

Quite a few: I'm not dissing Howard's movie: you can't tell a four day (actually, eight year) story in two hours without taking some dramatic license. Hence the article.

It's important to realize how much what-if planning work was done up front, before Apollo 13, so that during the accident, the controllers weren't just making it all up as they went along. In particular, the efforts of the lunar module controllers in this regard are absent from the movie, as are a lot of other key contributions.

Other issues: the CSM power-up sequence was not devised primarily under astronaut Ken Mattingly's auspices, but under EECOM John Aaron. Nor did Mattingly come up with the idea of running power back into the CSM from the LM: Bob Legler, a LM controller, came up with that idea months previously. In the movie, the crew were thrown around by the oxygen tank explosion: in fact it took a few minutes for everyone to realise something very serious had happened. And Kranz never said "Failure is not an option!"
