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 [apolloeecom.com] 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.

    Convert a LEM into a lifeboat, work out the proper equipment sequence to keep the power drain down to a minimum level, determine the correct trajectory with a "computer" roughly as powerful as a modern wristwatch, cobble together some CO2 scrubbers to fit where they weren't supposed to, and save three lives in the process. Tops pretty much anything else I've seen.

      To be strictly accurate, the heavy lifting on the trajectory side was done by a bunch of mainframes on the ground, in Houston's Real Time Computer Complex. But as the article says, they didn't have the software to compute how the trajectory of thecojoined CSM and LM would behave using the LM descent engine, so they had to call in a bunch of people to write new software! Then the burn parameters were passed up to be entered into the computer.
      • Presumably they had to change about two lines in the program; where it had the mass of the vehicle and the thrust of the lunar lander engine, and recompile/reassemble. Then they ran the program. Can't have been much more to it than that, if they got the answer in 2-3 hours...
        • by Anonymous Coward
          I don't know the details but I'd hazard it's little more complex than that: for example determining the center of mass and the turning moment about that center. I doubt it was as simple as "substitute the descent engine for the CSM main engine and change the signs"...

            Not to mention, we're (probably) not talking a simple "scroll down a bunch of pages and replace appropriate variables." While I'm pretty sure they weren't forced to use punch cards to program the simulation, we're still talking about mid-to-late 60's technology here, even if it was state-of-the-art for its time.

    If you look at all the stuff we were doing in space, including the heroics that successfully brought the Apollo 13 home, isn't it self-evident that was absolutely within our ability to land on the moon forty years ago?

    Now we're looking at Mars, but there's only so much duct tape we can wrap around these shuttles. I wish some of the enthusiasm and can-do attitude towards space that we had in the early days would return so that this next trek could be adequately funded and researched.

          That footage--the LM ascent stage blasting off--is from one of the later Apollo missions (possibly the last, but my memory isn't certain), and the camera was mounted on a lunar rover, and controlled from mission control by Ed "Captain Video" Fendell. Because of the lag between Earth and Moon he had to time his control movements a little ahead of time, a tricky job.

        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!"
        • Yeah, I understand the limitation of being two hours. I would love to see Apollo 13 movie expanded as a miniseries like From the Earth to the Moon [imdb.com] (great one!).

      Those of us who were around back then remember it being no less controversial, with just as much skepticism, and the same low regard from the Republicans over a program that was pressed by Democrats.

      The main mitigating factor was the idea that the space program would help stem the tide of Communism.

      The space age had an enormous impact on popular culture, but the politics were pretty much the same.
    • To be fair to NASA, there isn't much you can do in the two shuttle cases. The by the time the problems were obvious in the two shuttle disaster it was too late to do anything. In this case there was time to figure out what was wrong after it went wrong. I don't know if there is anything they could have inspected to see and prevent this problem in Apollo 13, but is wasn't near as serious as the Shuttle disasters.

    • As opposed to what happened back then, which was to build a space program out of the weapons technology developed during the twenty (or so) years previous. Assisted, in the brightest display of international friendship, by the former German V-weapon scientists and engineers. Further facilitiated by the computer technology originally developed to break enemy codes. All that for national pride, and an opportunity to one-up the Soviets.

      Yup, nuthin' good ever came of better weapon system.

    • YOu realize, that the big F-1 engines on the Saturn-V were a revison of ones designed for the military. The rockets for the mercury program were basicaly ICBM's. The whole program wouldn't have been done if it the research and development didn't have immediate miliatry applications. The military wanted to be able to put up spy satellites, and develop improved ICBMs. That's why the space program was so important.

    In the late 80's (Flight Test Engineer). A lot of the guys who worked on the LEM and where there during the accident were still around. Some sat next to me. I got to hear some really great stories about what happened, and the things they had to do.

    My favorite was that they (Grumman) got everyone who had anything to do with the program rounded up, put in a large room, and then they put an armed guard at the door. You could leave to go to the bathroom, that was it. They all stayed in there working on solutions and answering questions until Apollo landed, and apparently noone even complained.(Try that these days!)

    Also it was a tradition at Grumman to point to the LEM and what it did, and how well it was made. It set a very high standard that we were all expected to live up to, and were often reminded of.

    All those Apollo anniversaries make me sad. 35 years is my whole life, I was born the same year Apollo 13 made its epic return to Earth. And what happened through my whole life with space exploration? Are we further than we were in 1970? All that's left from the grand dreams of the period are some old shuttles, that make news when they fly at all, a space station which we wouldn't be able to operate without Russian (paid) help and a huge, costly government agency that produces lots of nice animations, small droids and very, very little substance - and tons of SF movies. In our silver screen dreams we have already conquered whole galaxy, in reality we hardly moved.

    One thing that struck me from reading that article is the enormous amount of flexibility in both materials and design of the spacecraft then compared to spacecraft now. I know many many people here on slashdot have pointed out that the escape systems on the shuttles were dropped in order to save money, but that's not the entire problem.

    From what I gather, the guys in mission control had to jump through many hoops to get things to work after the explosion, but firstly, they had practiced almost every possible problem, (the use of LM power to run the mission shortly after launch although it was blocked because of dead CM batteries and the CO2 filters which were recognised as necessary immediatley by one guy as soon as he heard the LM was to be used).

    The design and materials were extremely primitive by today's standards, but relays are a lot easier to reconfigure than a modern computer chip and the simplicity of the filters meant that with basic materials they could be reconfigured.

    In other words, the machines were vastly more robust than modern systems.

    And then there's the planning. They had actually taken, although not seriously enough initially, but later someone had decided to check that contingency out all the same.

    With the shuttles, there has never been a way to fix anything if the machine would fuck up in orbit. Nada. Costs too much. And what really absolutely amazes me is that NASA, that spends around $400 million on a single shuttle launch never thought about renting or buying 2 or 3 Russian Soyuz craft to be ready on a permanent basis in case something happened in orbit, and that even though Soyuz launches only cost a tiny fraction of shuttle launches, are far easier and faster to prepare and launch, and don't even cost much at all if they aren't launched and everything goes well.

    And no one, even after Challenger in 86, thought about checking out the shuttle regularly in orbit.

    In some ways, it's almost criminal neglect. What happened to NASA?
    • When the shuttle first flew, there was a concern about the tiles. I remember stories about how they flew the shuttle over a telescope in Hawaii to check the tiles. I also remember talk about a device that would squirt an ablative goo into the cavity of any missing tile. Lately, I hear that there's no way to repair tile damage in orbit. What ever happened to this device?
