Did an Unnamed MIT Student Save Apollo 13?

lukehopewell1 writes "When the Apollo 13 reported an explosion on board, NASA started a marathon effort to get the three astronauts home. Several options were considered, but history tells how flight director Gene Kranz ordered a slingshot around the moon. The story stayed that way for over 40 years, until this weekend when an ex-NASA press secretary came forward and said that an unnamed MIT grad student came up with the idea to slingshot the spacecraft around the moon. NASA reportedly buried his involvement at the last minute when it was discovered that he was a long-haired, bearded hippie-type.' Now the internet has gone on the hunt to find out who this unnamed hero really is."

He knew that at the end of the project orders might come down having the documentation destroyed as it has happened with the early efforts in the mid 1950's. He literally stole the documentation at the end of the program and kept a room full of it in his house until he died in Huntsville, Alabama. Then as a result the documents were donated to the US Space and Rocket Center and subsequently they are now being preserved for posterity. Orders were sent down from President Nixon and President Ford to destroy the documents. Had Lewis Sinko not stolen the documents they would not exist and one of the greatest treasures in all history would not exist now.

You might need an engineer with strong math skills to work out the orbit corrections to save fuel for later and come up with some ideas for the details, but the idea itself is quite straight forward. In fact I'm sure they didn't even consider any *other* option. I clearly remember a documentary where they mentioned that one of the problems early on was the power usage for calculating the math needed for the trip around the moon and back with the onboard computers. The engineers responsible had to promise they'd only need the power once to calculate the trajectory and wouldn't need it again thereafter. There had been a shortout and they were low on electricity after all.

    b) I doubt that anybody at NASA was in the mood or mindset for answering random phonecalls back then. Or today that is.

"We are 12 to 16 weeks away from having all the vibes in place to launch, orbit and land a hippie on the moon," Osmosis said, "as well as to return him safely to a big oversized floor pillow after wear-off and subsequent crashpad re-entry burn."

    The linked story is a great example of why you should never listen to what old men remember about great events and their (often "heroic") part in them. At no time did NASA need some graduate student from MIT to help them with a Guidance 101 type problem on Apollo 13. The difficulty was in getting the Lunar Module prepped quickly enough to make a small burn that would get them on a free return trajectory, the same type used on the previous four Apollo missions to the moon. Apollo 13 was the first to use a less safe trajectory so they could visit a more interesting place, Fra Mauro. There were always many ways out of a pickle and abort guidelines had been carefully developed for different phases of the mission. At the point of Apollo 13's explosion, a direct abort going straight back was never possible, not least because their big engine was in the now dead Service Module. Free return was the only option. There *was* a very famous "hippy" type guy at the MIT Instrumentation Lab, Don Eyles, who was responsible for much of the Lunar Module's landing program. On Apollo 14 he was instrumental in solving a problem that would have prevented that landing and he did get official recognition for it and there are pictures of him with his long hair and mustache. So that's another part of the Gizmodo crap article that is wrong. As far as the photos of the Apollo 11 astronauts on the moon go, there were about three pictures taken by Aldrin with Armstrong only incidentally in the frame. The shot with the flag is definitely of Aldrin, as you can see Armstrong taking the picture in the 16mm film taken from the Lunar Module window. Aldrin, unconsciously or deliberately, never took a proper picture of his fellow crew member and commander. It was only after Apollo 12 that a photo specialist at the Houston space center suggested red armbands for the commander to distinguish him in the photos and Jim Lovell, the Apollo 13 commander, never got to show them off, alas.

    The free return trajectory maneuver ("slingshot") was well known to NASA engineers, and was actually the default trajectory for all lunar missions before 13. The crew had to specifically fire the engines to enter lunar orbit. If the engines somehow failed to fire, the spacecraft was already on the proper trajectory to swing around the moon and return to earth . 13 was the first mission that was on a different initial trajectory, and required a change in order to get ONTO a free-return, but the "lunar slingshot" concept was obvious to all involved.

    The "long-haired hippie at MIT" who saved an Apollo mission was named Don Eyles, and the mission was Apollo 14. Picture of Eyles as he looked in those days here:

    http://pophop.tumblr.com/post/7532929166/m-i-t-programmer-don-eyles-posing-in-the-draper

    When a loose ball of solder inside the abort switch threatened to cancel the lunar landing, Eyles was called on to write a software patch that would bypass the switch and allow the landing to continue. Full story at the "LM Tales" section of his website, which is largely devoted to his post-Apollo artwork, photography, and sculpture.

    I am sorry, but this is BS as stated. The "Zond" direct return was certainly not unknown to the Apollo scientists. It's called a Zond trajectory because Zond 5 (launched 15 September 1968, returned 21 September) was the first spacecraft to execute it. (This would have been repeated with cosmonauts aboard if NASA hadn't have swapped the Apollo 8 and Apollo 9, putting men in lunar orbit in December, 1968, and thus upstaging a Soviet manned lunar flyby.) That was 2 years before Apollo 13.

    I also remember the Zond trajectory was _planned_ as a failure mode option for Apollo. I am sure there is discussion of that in the Apollo planning. I knew about it, and I was in High School at the time so I would bet serious money that Gene Kranz knew of it. I am not sure what the grad student actually contributed, but it wasn't the idea of the trajectory. (If I had to guess, I would bet he worked at the Instrumentation Lab - now Draper Labs - and calculated the delta-V needed to reenter safely, which is not negligible, but not the same as coming up with the idea.)

    Since many of the Apollo trajectory guys are still alive, if retired, I bet that someone will counter this in a day or so.

    For what it's worth, I was a student at MIT in the early 1970s.

Obviously, my memory from so long ago isn't perfect, what I heard at the time was a rumor anyway, and I haven't really tried to research anything that would corroborate it. That said...

    The story was not about Apollo 13, but about another Apollo mission that had established orbit around the moon. Some sort of faulty sensor reading or stuck switch was preventing the system from preparing the necessary rocket firings to break the astronauts out of lunar orbit and send them home. According to these rumors, NASA identified the author of the control code as an MIT student working at the Charles Stark Draper laboratory, which is affiliated with MIT. An emergency call went out to find him, so that he could patch the code to ignore the faulty switch or sensor.

    The claim is that the call was taken by friends, who were concerned by the fact that the student in question, whether long-haired or not, was either drunk or stoned out of his gourd at the time. Nonetheless, the student was alerted. He supposedly uttered the obvious "oh !$!$!" and stumbled off to Draper Lab, where in his reduced condition he patched the code and saved the astronauts.

    Very much a rumor/urban legend, but suspiciously similar to the new story about Apollo 13. These certainly were the sorts of stories that floated around MIT at the time. I expect that at least a small percentage of them are true.

Third option would be to speed up, still use the moon, and achieve the same effect. I'm pretty sure at the point that they were deciding what to do, NASA had pretty much every employee awake and on the job. It's a bit presumptuous to assume that none of them came up with the slingshot idea on their own, considering going into an orbit of the moon was part of the initial plan of the mission in the first place.
