Tonight (at 02:56 UTC to be exact) it's 50 years since, what most people regard
as the most impressive accomplishment ever in human history took place. The first human being set foot on another heavenly body but our own Earth.

In fact, this was such an enormous achievement that even today there's a lot
of people who are still convinced that it couldn't have happened; it simply was
far beyond what was real, if for no other reason with the technology we had then.

While I'm sure that Neil Armstrong will be mentioned millions of times throughout the world tonight, I'd like to mention the woman who contributed to make it all happen: Margaret Hamilton.

One of the Lunar Landing Hoax believer's main objection is, that the computers by then were far to big and power hungry to fit into a lunar landing module or even the vehicle taking it to the moon.

Well, Margaret, now 82 and still kicking, by then 32, did make it happen. There were no computers onboard any of the vehicles, at least not what we call computers nowadays. It was more like the first ever embedded systems.

Those systems were designed to be foolproof. Absolutely 100% foolproof, not 99.99%. And she made it happen. Still today they are regarded as the most reliable embedded systems ever created, with error recovery functions that still to this day put shame on Microsoft and other major software companies.

Here's thinking of you, Margaret! At the age of 32 you really made it big time in the man's world that you lived in by then (and still today). Software engineers around the world still remember and salute you. Sk�l!

Mmm... did she know Dan? Or Frank? I wonder how she fitted in with their personal experiences.

Hmm... What I read today is that at 300 meters the "computer" in the lunar lander crashed for the fourth time in five minutes. It rebooted relatively quicky without loss of information but for seconds Armstrong and Aldrin were flying blind without height information.

Armstrong was selected for his cold-bloodedness and it paid off. He did not loose his nerve during the landing. With a "computer"crashing every other minute, unexpected obstructions at the landing site and only 18 seconds of fuel
left in the end, I do not think many others would have pulled it off.

When at age 17, I went to university in 1963 and took astronomy as a secondary,
I was introduced at the Utrecht Observatory. With my fellow students I looked at the moon through the "Big" Telescope. The 25 cm Merz refractor. Max Kuperus,
the then bachelor showing us around said: people are going to walk there and we
are going to live to see it. Six years later it happened and I lived to see it.

I sure have lived in interesting times...

Cheers, Michiel

The first heart transplant was so much more impressive.

Hmmm ... the code has been released and was in a language and hardware unique to the Apollo program. Stuffing routines in 4KB or 8KB memory was not unique nor state-of-the-art but daily business then. Been there, done that, got the t-shirt.

Margaret was part of a team, not a solo player as demonstrated by the annotated
print-outs which survive.

And both Lunar Lander as well as the Command Module had computers, they crashed
more than once during critical flight moments.

They were NOT foolproof.

The ACG was right, the error was injected by the LEM radar (a known bug discovered by the former Apollo mission but never fixex, maybe an ancestor of Poettering was the designer of the radar?). ;)

The bug was in the radar system of the LEM.

By then? I seriously doubt both your statements.

I made it a decade later with my Motorola 6800 based embedded system (not a computer!).

I learned it in 1975 on a Intertechnique Multi 8. A French minicomputer with 8K
ring core memory. It was given into my care in Tijgerberg Hospita, Cape Town. I
was the lucky one because I was the only one that could read the manuals writen
in French. I taught myself to program in assembler on that machine.

"State of the Art daily bussines by then"? No way Jos�! ;-)

I made it a decade later with my Motorola 6800 based embedded
system (not a computer!).

Same here. I later converted that "embedded system" into a real computer. Flex OS and 5 inch floppy drives. Later 6809 with 16 MB hard dive. Those were the days... ;-)

Me too. I built from a description in a Swedish computer magazine. I still have it here somewhere, with the 5 1/2" disk with the Flex OS on it.

I'm a bit younger than you two... :P

I Started my work life on an 11/780 Vax system, that we used to meta-assemble code for custom boards for Electronic Warfare.
In the same environment I worked also on HP64000 with pods to debug the code on
that boards and on a rare Texas T9000/12

Yes! Real code, real languages (I wrote code in assembler, Pascal, Fortran and C in the beginning era of C), real iron! :)

All ended with the advent of the PC.

Hello Björn,

Tonight (at 02:56 UTC to be exact) it's 50 years since, what most people regard as the most impressive accomplishment ever in human history took place. The first human being set foot on another heavenly body but our own Earth.

Not everybody is convinced.

In fact, this was such an enormous achievement that even today there's a

lot

of people who are still convinced that it couldn't have happened;
it simply was far beyond what was real,

Most people alive today have no recollection of such an event ever
taking place. For them, it is all a fairy tale.

If we really did land on the Mooon as we have been told, why have we
not returned in almost 50 years? That question alone brings up many
other questions.

We really landed there and found nothing interesting - just craters
and dust.

We really landed there but nobody told the public the interesting
stuff.

We really landed there and found evidence of previous advanced
human civilization and technology on the Moon because humans made
it into space before the last catastrophic event. Plato wrote
about it, describing what happened to Atlantis.

We really landed there and found evidence of aliens observing us
on the far side of the Moon as their base. Pink Floyd sang about
this on his album, "Dark Side of the Moon".

We never made it to the Moon at all. It was just propaganda.

So. Which story do you want to believe?

if for no other reason with the technology we had then.

A blogger has challenged that notion. Read on.

While I'm sure that Neil Armstrong will be mentioned millions of times throughout the world tonight, I'd like to mention the woman who

contributed

to make it all happen: Margaret Hamilton.

Yes, of course. We only sent men to the Moon. Never women.
That is why NASA has decided to come clean, and is planning a
remake of this event -

As a tribute to the 50th anniversary of its fake moon landing, the
National Aeronautics and Space Administration has announced a reboot
of the staged event that fooled billions worldwide, only this time
featuring an all-female crew.

NASA officials confirm they will release a shot-for-shot remake of the meticulously concocted phony moon landing, originally filmed at an
undisclosed soundstage 50 years ago this week. The rejuvenated hoax
will follow in the footsteps of other recent all-female reboots like Ghostbusters and Ocean’s 8.

“Those were some great buddy films,” a NASA spokesperson told reporters, “but we made the ultimate buddy movie in 1969 when we tricked all those people with Neil, Buzz, and Mike. We thought a modernized update was
the perfect way to mark the occasion.”

Rumors claim the part of Neil Armstrong will be played by Scarlett
Johansson, with Melissa McCarthy acting in the role of Edwin “Buzz”
Aldrin. The Michael Collins character will be portrayed by Dame Judi
Dench.

According to sources, the only change in the script is a more inclusive
update to Armstrong’s famous words when setting foot on the moon, which
will be replaced with the line “That’s one small step for a woman, one giant leap for womankind, mankind, transgenderkind, genderfluidkind,
and otherkind.”

One of the Lunar Landing Hoax believer's main objection is, that the computers by then were far to big and power hungry to fit into a lunar landing module or even the vehicle taking it to the moon.

One blogger challenged hoaxers everywhere with this - "You cannot name
even one single piece of technology that would be required for a 3 day
trip to the moon that would be outside of relatively well understood
and very publicly known aerospace engineering technology of the 1960s.
Go ahead and try. I dare you."

He claims he has been waiting over 10 years for them to come up
with something. I presume his challenge remains open.

Well, Margaret, now 82 and still kicking, by then 32, did make it happen. There were no computers onboard any of the vehicles, at least not what we call computers nowadays. It was more like the first ever embedded systems.

The main engineering obstacles seem not to be a need for new
technology. That is what so few (if any) hoaxers truly understand.

The lack of a launch rocket capable of boosting the payload -
a manned capsule - followed by NASA's wants (not needs) of developing
equipment to get water and hydrogen from lunar dust, and to build
a lunar space station first (before anybody else).

Why would the US want to land a man on the Moon? The US wanted
to show the USSR it had the capability of striking a target with
a ballistic missile from 240,000 miles away. The part about a
man stepping on the surface of the Moon was a PR stunt for the
masses.

That is what you had. Three monkeys sitting on top of a ballistic
missile, launched towards a target a quarter million miles away.

Yes, Margaret Hamilton deserves special credit for what she has
done to have made it possible for NASA to have completed its mission.
But so many others also deserve credit. After all, it was a team
effort.

They did all this using technology that existed in their day. That
is what is so remarkable. No help from ancient artifacts found
in Egypt or Atlantis or other lost civilization. No help from ETs
who crashlanded at Roswell, New Mexico.

Those systems were designed to be foolproof.

There were backup systems to backup systems. Not even the best
designed systems could not be expected to perform perfectly, in every situation. And even then, that still was not enough, as "Buzz" Aldrin
had to use his felt-tip pen to fix a glitch that would have kept the
lunar module from lifting off the Moon.

Absolutely 100% foolproof, not 99.99%. And she made it happen.

Nothing is "absolutely 100% foolproof" - as demonstrated.

Still today they are regarded as the most reliable embedded systems ever created, with error recovery functions that still to this day put shame on Microsoft and other major software companies.

It was certainly an engineering feat. Assuming it was not a hoax.

Here's thinking of you, Margaret! At the age of 32 you really made it big time in the man's world that you lived in by then (and still today). Software engineers around the world still remember and salute you. Skål!

So. When, if ever, are we going back to the Moon?
When, if ever, will we travel to Mars? And beyond?

Maybe I'll have to satisfy myself by reading more of Edgar Rice
Burrough's tales. All true stores, according to him.

Why? IIRC CP/M loads in about 8KB of RAM (for the youngsters, CP/M was
an operating system for 8080 and Z80 based computers).

By then -- as in the first lunar landing -- those microprocessors are at least a decade away.

Somewhere around here I have a program I wrote to run under CP/M that calculates the date of Easter for any year since (I think) 1583 - the
calendar was radically changed in that year. I haven't looked at it
since probably 1980 but I think it loads in 2KB of RAM
