Apollo 11's 35th Anniversary
colonist writes "35 years ago, on July 16, 1969, Apollo 11 began to achieve the goal set by the late President Kennedy: '...before this decade is out, of landing a man on the moon and returning him safely to the earth'. On July 20, Michael Collins orbited the moon in the command module Columbia while Neil Armstrong and Buzz Aldrin descended to the lunar surface in the lunar module Eagle. The descent engine was halfway through its final 12-minute burn when a yellow caution light lit up on the display of the lunar module computer. [ARMSTRONG: Program Alarm... It's a 1202. ALDRIN: 1202. (Pause) ARMSTRONG: (To Buzz) What is it? Let's incorporate (the landing radar data). (To Houston) Give us a reading on the 1202 Program Alarm.] Buzz Aldrin's recollection: 'Back in Houston, not to mention on board the Eagle, hearts shot up into throats while we waited to learn what would happen. We had received two of the caution lights when Steve Bales the flight controller responsible for LM computer activity, told us to proceed... We received three or four more warnings but kept on going. When Mike, Neil, and I were presented with Medals of Freedom by President Nixon, Steve also received one. He certainly deserved it, because without him we might not have landed.' Fred Martin describes the incidents, and Peter Adler looks at the design of the system."
Personally, I prefer The Onion's coverage of the event. Fair and balanced, you might say.
For anyone who has HBO and hasn't seen it, there is a twelve part 'docudrama' on HBO called "From Earth to the Moon". It covers the all the Apollo missions and is absolutely fascinating. It is available now if you have On Demand.
And marvel at what was, and think back of what we thought could be, and see what is, I ask simply WHY?
Rhymes that keep their secrets will unfold behind the clouds.There upon the rainbow is the answer to a neverending story
Written by the mission controller throughout the whole thing.

and we haven't done much at all comparable since.
That's not to say that NASA hasn't done some great things since or recently (Hubble, Pathfinder, Opportunity and Spirit, Voyager, Pioneer all spring to mind immediately), but there hasn't been a significant excursion into space by mankind since the last Apollo mission.
Well, maybe the ISS counts for something in that regard. *shrug*

There is an interesting Book out now called Lost in Space : The Fall of NASA and the Dream of a New Space Age ( http://www.amazon.com/exec/obidos/tg/detail/-/0375 421505/qid=1089999998/sr=8-6/ref=pd_ka_6/002-29955 58-2684827?v=glance&s=books&n=507846 ) which deals with this time in the history as well as the current time. I've been hearing that it is rather good and gives you an understanding of how NASA came to be the great beurocracy it is now ...

...the greatest achievement man has done yet - I was 10 at the time, and can still remember looking up to the moon and thinking men were walking about on it

Man, this is such a troll but I'll bite.
Getting to the moon was an unbelievably complex and difficult thing to do. in retrospect it seems doable since we know it's been done but keep in mind that this was the first time this was all done.
Keeping a system of mechanical, electrical and information systems working together flawlessly is beyond most engineering feats today. If a single thing went wrong back then it could have meant the failure of the mission and loss of crew not to mention international shame. Some of the best minds in the world worked in this so to call them dumb is both ignorant and an insult to their effort.
ok, I'm done venting.

Members of the model/amateur/experimental rocket community are holding a celebration of sorts online. Rocketers are invited to logon to The Rocketry Forum (http://rocketryforum.com) and be onine across the time point Tuesday, July 20, 10:56:15 PM EDT. This is 35 years to the second from Armstrong's "one small step". Many will be in chat, but the main point is to get as many people logged onto the board as possible during that time. Even if you've just a passing interest, drop by and check it out, and help out with the numbers just by being there. Or sign up (free) and hang around.

35 years ago we put a man on the moon.. Pretty awesome if you ask me.
What kills me is that people exclaim how the iPOD, XBOX or Furby is "revolutionary" or will change how the world does [insert buzzword here].
I wonder how many high school students today even know we put a man on the moon...
(Impressive how I can keep typing while on fire, isn't it? Now where was I? Oh yeah.)
Aaaghhhhh!!!!!!! Help ME!!!!
Kennedey was not a war president. Instead of using the military industrial complex to float the US economy, like many presidents, he used NASA. This gave the people a goal and boosted the nations pride without having to stomp on a smaller nation. If the US spent half of the military budget on NASA our world would look far different. Science and technology have shown their ability to create massive wealth and prosperity. Look at what a tech focus did for the Clinton era. Let's revive the NASA era. Afterall we only have a few billion years left before this rock is engulfed by the sun. Possibly less than one hundred years before our lust with war obliterates our home.
WURD!!
According to http://www.hpmuseum.org/hp65.htm, the HP 65 was introduced in 1974, far too late to participate in any of the moon missions, but it did fly on Apollo-Soyuz and got some use doing course corrections there.

Barely related, but from article about the onboard computer:
"each time a 1201 or 1202 alarm appeared, the computer rebooted, restarted the important stuff, like steering the descent engine and occurred."
It's a good job they weren't rebooting any modern system + OS, otherwise they'd have left just another inconsequential moon crater rather than footprints.
You had to join the military
AND You had to get more degrees than a thermometer
2. How many of you think that "Apollo" is only a character on "Battlestar Gallactica"
For those of you who are non-American, let me explain: In America, we have become SO polarized that the moment a democrat says something, a republican immediately says "why it's wrong/why he's REALLY doing it for some evil purpose" - and vice versa. I guarentee you, Al Franken has already decided that whatever Bush will do in 2006 (if elected) is already wrong, EVEN BEFORE HEARING IT! Same way that republicans ALWAYS said clinton was wrong (When Clinton bombed Iraq in 1998, Republicans said it was only to distract us from Monica). And yes, Rush already agrees with whatever Bush agrees with and hates Hilary Clinton's Senate bills even before they're presented. This goes both ways.
Today, had president X said that we have to unite as a nation and go to Mars by 2016, the other side would immediately say "It's stupid/useless/waste of money/just a distraction from (problem Y)."
Was Kennedy's space-race politically motivated? Yeah. Is it a good thing it happened? From my point of view... definately. Science doesn't know politics. Martian soil doesn't really care about WMDs or Gay Marriage. I hope that the next leader to make such a bold statement is met with some sort of unity, and not bickering. (But it won't).
As Chris Rock said in his latest comedy special about partisan politics: "Anyone who decides on an issue... before hearing the issue... is abolutely f*@&ing crazy!"
When I was eight or nine years old a neighbor gave me a copy of The Invasion of the Moon 1969 by Peter Ryan. I've read it at least a dozen times since then.
It's a paperback, mostly consisting of transcripts of the communications between Mission Control and the Apollo 11 mission, with commentary and explanation interspersed.
Sadly, the book is long out of print, but you can find used copies through the usual sources. I bought one a couple years ago for a friend who read mine and liked it.
As I understand it, it was more of a watchdog timer interrupt than a reboot: the 'operating system' would run through the tasks allocated to it in order of priority and if it hadn't finished those tasks in one 'tick', an interrupt would raise the program error and jump back to the start. Low priority tasks like updating the displays would get dropped, but the important stuff like navigation and controlling the engine would be run properly.
Although the article above links to a portion of this site, the full Lunar Surface Journal offers an incredibly detailed look at the Apollo program, including audio, video, and high resolution images from the missions. Be warned, you will spend hours there :).

I wasnt born then. Still there is a lump in my throat when I read those words. I wish I am alive when we hear something along these lines when we touch down on the Red Planet..or even farther..
Wish for a moment, we could stop all this crap going around and remember those brave souls who perished in our urge to leap higher and honor their souls by setting higher goals and achieve them.

A major stop on NASA's space center tour is the moonwalking shrine.The tour leader beams with pride, but I am saddened by NASA's lack of progress in manned space exploration the past 35 years. Its a dusty old museum of past glories.
In spite of our half-trillion-dollar deficit, the Bush Administration is going to send humans to Mars someday.
I say, lets start today... With George W. Bush...
In the 60s we looked ahead, learned from failure, tried again and landed on the moon.
Now when we fail, we look back, assign blame, postpone, assign blame, and postpone some more.
It is better to be the hammer than the anvil.

It was sounded because the computer was receiving more instructions than it could handle and it was getting to the point where it would have just stopped executing them, leading to an abort.

Quoting Fred H. Martin, At the time Deputy director of mission development;
'I remember bumping into one of our M.I.T. engineers, George Silver, who was usually at our office at Cape Kennedy. George had been involved in and witnessed many pre-flight tests. I asked him in frustration if he had ever seen the Apollo Guidance Computer run slowly and under what conditions. To my surprise and rather matter of fact, he said he had. He called it "cycle stealing" and he said it can occur when the I/O system keeps looking for data. He had seen it when the Rendezvous Radar Switch was on (in the AUTO position) and the computer was looking for radar data. He asked "the Switch isn't on, is it?" "Why would it be on for Descent, it's meant for Ascent?" '
Sorry, this is embarassing but I cant seem to figure out how to make the URL's link to articles, and none of the 'allowed HTML' seems to work for that purpose. I would appreciate if someone could explain to me how that works!
I have been reading Robert Zubrin's Mars Direct (borrowed from my father-in-law) and yesterday I came to a conclusion. I must mention that I have some very deeply held political ideology: I am a strong anarcho-libertarian. I believe all taxation ought to be repealed, the purpose of government ought to be limited to defense of rights against aggression, important government projects like space exploration ought to be handled through voluntary donation and/or private enterprise, and government ought to relinquish its monopoly and allow competing governments to be set up within the same geographic region.
HOWEVER
Reading Mars Direct yesterday I suddenly found myself just amazingly mad. Yes, space exploration ought to be handled by private enterprise ... but the reforms needed to bring about the ideal libertarian society I believe would handle this are decades off and will probably not occur in my lifetime. Meanwhile, the government is still taking our money ... and what are we getting for it? Mankind has not set foot on the moon in my lifetime, and even if he did I'm not sure what it would accomplish. But Mars has been sitting there, waiting. How many billions of dollars have been spent on the space program since man landed on the moon in 1969, and why have those billions of dollars not gotten us to Mars?
If they are going to take my money away to support space exploration, something I would have voluntarily given my contributions for, they ought to at least produce what they promise to deliver. But we're sitting on earth, noone is in transit to Mars, and noone is there to look at these emissions of ammonia and methane to see if it's rocks or life.
And the saddest thing of all is ... for a mere 20 billion dollars, someone could be sitting there right now to answer our questions for us. That's awful.
So yesterday I threw a lot of my principles out the window. Yes, I don't believe space exploration should be handled by governments instead of private industry ... but for crying out loud, it ought to be handled, somehow! And we shouldn't have to wait until my grandchildren have grandchildren to see it. It can be done, now for $20 billion. It ought to start TODAY. George Bush (I like him; I know many of you do not) should be on the news, announcing that we have a plan to take us to Mars in less than 10 years for 20 billion dollars, and it starts today. Congress ought to be passing the paperwork as we speak. This is more important than just about any other political issue. This is about the future of the human race. Are we going to stagnate, or are we going to explore the new frontier?
And you know what? That $20 billion is trivial. Governments spend that all the time. That's less than 1% of the national debt. And after all the trouble we went to to get a balanced budget, we're currently running a deficit again. Look, if we can pay off $3 trillion (that was the national debt when I was about 15; I don't know what it is, now) at some unidentified future date, we can pay off another $20 billion at some unidentified future date. Quit whining, borrow the money, and do it! The plans are sitting on your desk.
NASA could be scrapped and we'd free up $15.5 billion for this project. But actually if we spread the plan out over ten years, it's only $2 billion. Half of NASA's plans are silly float humans in LEO plans that are doing nothing, anyway. (Many of these are designed to research irrelevant Mars mission scenarios, like long term effects to zero-g. Mars Direct provides for spinning the transit vehicle (duh!) to provide gravity. What a waste!) Drop a few of those, free up the money, and do it. Better yet, forget NASA altogether. Let NASA go ahead with their work (yes, much of it is excellent; I'm just in rant mode; the rovers are great, the probes are great, but the places we are sending humans stink). Meanwhile, we could just increase
Secession is the right of all sentient beings.

Although he claimed that he wasn't bitter about being left in the command module, Michael Collins spent his time alone by replacing Neil Armstrong's Tang with Metamucil and reversing the direction on the toilet hose.
During their training, the Apollo 11 astronauts were taught to identify over 1200 varieties of cheese, "just in case..."
Buzz Aldrin's capsule record of 72 zero-G somersaults before puking has never been broker.
Mission Control was commanded to whisper while Buzz Aldrin was hitting a golf ball.
The following conversation occurred during one of the lunar rover expiditions, but was quickly hushed up:
Buzz Aldrin stated that his biggest regret was that he 3-putted Mare Imbrium.
Alane would probably give an Isp of about 300-310 sec in an actual rocket. While that's very good for a solid, and is competitive with LOX/Kerosene, it's nowhere near Lox/LH2 which is typically about 450 sec for a good engine such as the SSME or newer RL-10s.
Doom. Quake. Unreal Tournament. All games where you play the role of a hero against insurmountable odds. All deliciously showy and fun as hell. But... Could you step into the shoes of an actual hero and land Apollo 11?
Download Eagle Lander 3D and find out. From their home page:
I don't know about anyone else, but this simple simulation has somewhat skewed my view of FPS games. I have passable 5k1llz in QuakeWorld and UT, but they are absolutely useless trying to land a LEM. Patience and attention to detail are the key here, not twitch-and-fire. (You couldn't "twitch" a LEM, anyway.) I've played Eagle Lander a bit, and I'm no damn good at it.
Think about that for a second. I've wrecked a LEM several times in this game/simulator. Hey, no big deal, right? Just restart the game. Now, think about Neil Armstrong, sitting there in the middle of what's essentially the ultimate desert, a half million miles from home, being watched by a billion people, flying this tiny little metal can, trying to kiss the surface of the moon. Granted, he had years of training in simulators and mockups, but this is the real deal, and he absolutely cannot fuck this up! No retries, no $0.25 for three more lives. One shot. Success or absolute failure.
Now, keep that frame of reference in mind when you grab the controls of Eagle Lander 3D, and see if it doesn't even slightly mess with your sense of gravity about what you're doing (pun not intended).

35 years ago, we put flags on the moon.
Now we spend our efforts dealing with folks with moons on their flags.
