No, the van Allen radiation belts weren't deal breakers for the Apollo astronauts. They really did go to the Moon. Want weekly Vintage Space ? Don't forget to SUBSCRIBE! www.youtube.com/channel/UCw95T_TgbGHhTml4xZ9yIqg

Look at the eentsy weentsy wobbly piece of equipment that blasted ferociously off from the moon please

www.youtube.com/watch?v=yn1S- flYkaQ

And tell us why there are no jets of flame or exhaust under it. Do you honestly think it connected with the rocket orbiting earth at 4000 mph thru space for the return trip?

if there is no oxygen then there can be no combustion thus no thrust.

While true, the difference between a jet and a rocket is precisely that a rocket carries it's own supply of oxygen, while a jet takes it from the environment.

The moon landing used rockets.

While the US government has lied about many things, I don't consider the moon landing to be one of them. All of the landing sites can be and have been photographed from earth and show signs of activity. The various claims of evidence of it was faked have been debunked, at least to my satisfaction.

Why did they stop the moon walks, Ping, and why are astronots and other experts talking today as if they never happened?

Donald Pettit says we "destroyed" the technology and it's too "painful" to recreated it. In other words the dog ate my homework?

Why did they stop the moon walks, Ping,

Because there's no financial reason to continue them. It's a rock. There are no natural resources there to be harvested. With no public will, there's no political will. It was and would be expensive to return, with little to no reward for doing so.

and why are astronots and other experts talking today as if they never happened?

That astronaut looks all of 27 years old, and while the context is unclear, it's probably nothing more than him embellishing the space hazards of the van allen radiation belts to impress his audience. There are 2 separate belts and the main one is donut shaped above the equator. The Apollo missions simply exited earth's orbit at a higher latitude to avoid the worst of it, and in any event, was through it in a short enough time to avoid significant exposure. Supposedly it would take a month to absorb a lethal amount of radiation in the belts.

As for electronics, 60's tech didn't used transistors which are everywhere today, but vacume tubes which are immune to radiation. I don't know how transistors hold up to radiation. Maybe they require shielding that the Apollo missions didn't require.

One could probably raise all kinds of similar claims about how internal combustion engines should not work because of heat, lubrication, timing and a myriad of other issues involved. But just because the common person doesn't understand everything about how the internal combustion engines work does not mean they are a hoax. Obviously they do work. By the same token, it's not fair to require one understand all issues involved with the Apollo space missions to conclude they were real.

Edit:

Photos of the moon from earth show the landing sites with prior activity consistent with the Apollo landings. It's there for everyone to see 2 weeks out of every month. Would that not be sufficient proof?

Looking this up, it appears the photos I've seen have been from NASA's lunar orbiter, not from earth, and one site argues that even the Hubble scope doesn't have the power to show the moon landing activity, much to my surprise.

The below are the images I referred to, but they are apparently from Lunar orbit, not earth, so could be suspect.

The Apollo Guidance Computer used transistors, not vacuum tubes. The CPU was made from Resistor-Transistor Logic (RTL) integrated circuits. The RTL circuitry didn't rely on electric charge to maintain the state of its sequential circuits, so it was less susceptible to cosmic ray induced errors than more modern circuitry would be. The magnetic rope (read only) memory was probably pretty safe, and I would guess that the magnetic core (RAM) memory was also.

Thanks. Sounds like it's your area of expertise.

I realized I was thinking of EMP bursts, not radiation, that would blow out transistors but would not affect vacuum tubes.

That according to my college engineering professor, at least.

Flashback! I can vaguely remember an RTL based logic trainer in our high school electronics lab 40 years ago.

Yes, the old tubes (before my time!) were more tolerant of transient overvoltage events than semiconductors tend to be. I reckon NASA must have considered the probability of a catastrophic solar flare during the mission, and NASA and the designers at MIT probably took steps to reduce the system's vulnerability to EMP. Lots of variables -- not just the circuit design per se, but also shielding, cable routing, etc.

A tube based computer would probably not have been feasible for such a mission? -- too large, too power hungry, too slow, and too unreliable (for reasons other than EMP susceptibility).

Tubes are still being used in high power applications like radio transmitter towers. Can't play guitar, but when I mentioned trying to learn to my brother, 20 years ago, he set me up with a Danelectro and a little Silvertone amp. The smell of those tubes warming up is even better than the smell of money.

Anyone remember the old tube tester machines? They were pretty ubiquitous up to 1978 or so. Mostly in malls, drug stores, and TV shops.

I was stuck sorting tubes for an entire weekend when I was 14 or so. My Mom's cousin had bought from estate sale...it was actually kind of fun.

It sounds like it. I'd almost rather have tubes than transistors since the tradeoff seems to be that you can get electronics repaired anymore except mebbe TVs. I used to could get ANYTHING fixed -- they even replaced buttons for on old boom box!

Planned obsolescence is much more refined and advanced than it was back then. Growing up I remember only a single toaster that seemed to last forever. And if a nichrome heating element had burned out, it would have been replaceable -- just wind a new one. Nowadays we have to buy a new toaster oven every 2 years or so. Lots of products are throwaway today -- by design.

Some low cost printers actually have a counter chip in them that disables the product after so many thousands of pages. Some German kid figured it out and made a YouTube video exposing the whole scam. And -- as I recall -- how to reset the count!

I don't know; haven't personally had a printer die on me like that.

The light bulb lifetime limitation conspiracy story is pretty interesting; an early and disgusting example of planned obsolescence to maximize profits.

Lastime a printer quit on me it was coincidentally the bulb. I took it to Inksters for a diagnosis and they were willing to fix it for a small fee, but Inksters is gone like so many of my favorite businesses -- casualties of the Bush-Clinton-Bush-Obongo depression.

Latest printer weirdness: older one will print from hardrive but not glass pane. An HP 6210 which has to be 6 or 7 yrs old and has weird problems like the upper part refusing to settle neatly = hinge failure, just like its HP predecessor.
