Ah yes! the Lunar rover,

Wiki.
Daytime on one side of the moon lasts about 13 and a half days, followed by 13 and a half nights of darkness. When sunlight hits the moon's surface, the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down, temperatures can dip to minus 280 F (minus 173 C).27 Oct 2017

NASA.
Like the human body, the Exploration Rover cannot function well under excessively hot or cold temperatures. In order to survive during all of the various mission phases, the rover's "vital organs" must not exceed extreme temperatures of -40° Celsius to +40° Celsius (-40° Fahrenheit to 104° Fahrenheit).
The rover's essentials, such as the batteries, electronics, and computer, which are basically the rover's heart and brains, stay safe inside a Warm Electronics Box (WEB), the Heaters are packed inside the rover body, and like a warm coat, the WEB walls help keep heat in when the night temperatures on Mars can drop to -96° Celsius (-140° Fahrenheit). Just as an athlete sweats to release heat after an intense workout, the rover's body can also release excess heat through its radiators, similar to ones used in car engines. <--------

I think the point is that the lunar rover maintained a suitable temperature range by losing heat to the surroundings only by radiation, because evaporation, convection and conduction as methods of heat transfer are not available on the Moon, because the Moon has no atmosphere. The rovers did not use a working fluid such as water to transfer heat from the engine to the radiator as ordinary cars do, but instead the radiators were in direct thermal contact with the batteries and other equipment. The performance of the radiator was affected by being covered by moon dust, and dutifully measured and recorded. Who could possibly have faked all of this?

The more I read about the Apollo missions, the more impressed, indeed amazed, I am by the staggering depth, detail and brilliance of the application of scientific and engineering principles to bring about this triumph of human achievement.

Well not necessarily maybe they ‘lost them’ so people couldn’t investigate them properly in future and check for evidence they were faked. Imagine the standard of cars in the 60s it’s amazing that they managed to make a rocket that could take Man to the moon.

I can understand people questioning it

Exactly, I think that's where they maybe got the tires for the Rover,(Lunar car, not the earth car)...

So how did they dissipate the heat in the suits worn by the astronauts, the temperature can reach 260 degrees Fahrenheit, remember this is back in the 1960's mate, so you have to factor in the techno of the time.

And that's exactly what you've just done... you can't use a vehicle in those temperatures unless it was designed for them, the cameras would also melt, there was no modifications other then larger controls for their gloved hands, now take a look at it man, where the fuck did they get those wheels and tyres from? Alex Smiles?
Surely, they'd design something lightweight, not a lump of junk like that, I've built better looking boogies when I was a nipper, now take a close look at the official NASA photos of the landing craft, it's held together with gaffer tape cardboard and building paper and why is there random bits of shiny gold tape stuck willy -nilly all over it? I wouldn't get on that in a fairground, never mind expecting to travel to the moon in it, my guess is you're a Treckie and desperate to believe all this shit.. By the way, I've already stated I don't know what shape the earth is.


PS, they lost the technology to get to the moon too,that's why they reckon they've never been back... can you believe that?

I tried to leave it as I didnt want this to turn into shit throwing contest but you did just that.

A lump of junk? gaffer tape? and willy-nilly?
Not phrases you usually hear when talking to somebody who has read and educated themselves on the subject. You have offered no knowledge in this thread but keep going on like you know more than a group of people who were/are much, Much smarter than you.

My guess is you are an idiot who's ego wont let him believe he is thicker than a whale omelette.

It was the Treckie remark, wasn't it, hit a nerve eh! never mind mate, with your super intelligence, you'll get over it.. Nanoo, nanoo!

 

[SAFCOldie]

Sorry but that makes no sense

It does in my head Probably good reason for the disrecpancies but I can't understand how it seems we had better technology/reliability 50 year ago, e.g. from this latest China moon visit..the sum total one grainy photograph (unless they are keeping a lot back) ?

Not a trekkie mate i'm afraid, although with my 'super intelligence', I can spell it correctly!

127 Celsius that you quoted is cooler than the element of a kettle, being not that much over the temperature of boiling water. My oven has rubber seals around the door and can run to 230 degrees C. I would be quite surprised if a lunar rover melted to a puddle unless for reasons unknown NASA chose to make it out of chocolate.

The more I read about the Apollo missions, the more impressed, indeed amazed, I am by the staggering depth, detail and brilliance of the application of scientific and engineering principles to bring about this triumph of human achievement.

It was an amazing time and some of the lack of safety rules, did allow them to wing it a bit and be really creative.

I do think Voyager I & II do trump them (but not by much) for our greatest achievement. It was only 5 years before launch that someone said "Hey, the outer planets are coming into alignment, if we could build and launch some craft, we could visit them all in the same mission". 5 years from idea to launch and 42 years later this summer, they are still going and have left our solar system.

The maximum operating temperature limit of the car battery was 125F , survival upper temperature limit 140F , minimum OT 40F Minimum ST -15. mate, wasn't suggesting the car would melt.
Like I said earlier. what about the astronauts, how did they keep cool/warm in those kind of temps, It was an amazing time, but technology was far from cutting edge.

I wonder if they had thought about this and built in a cooling system?......

If I can look this up, why can’t you? It is interesting, though, that spacesuits keep you cool, not warm.

I already have, I'd imagine they would have been designed to keep you warm too though, wouldn't the temperature plummet in low space, so they would need to heat the suits for any work outside the shuttle to be carried out? or, if those moon landings hadn't gone to plan and the lads had to work on the module in darkness or any shade, lucky everything went spot on first time, without any practise mind.

I agree that Voyager and the other deep space probes are wonderful, and have done so much to extend our knowledge of the Solar System. But the sheer courage, coolness, resourcefulness and modesty of the Apollo astronauts adds such a breathtaking human dimension to their missions that I, for one, am lost in admiration.

Spacesuits are really good insulators of heat. The human body emits about 100W of power so unless this is removed from the suit the wearer will quickly overheat. The only external heat supply is the sunlight incident on the suit-about 1500W/m2. Spacesuits were white in colour to reflect a lot of this radiant energy away. The designers knew what they were doing, and weren’t working on ignorant misunderstandings of basic science.

There's an excellent documentary on Netflix currently about Flat Earth, definitely worth a watch.

Behind the Curve.

Really gives excellent explanation to people's reasoning behind this new anti-intellectual, anti-science movement

I've only seen some clips of that one. Specifically, the clips where they conduct experiments (proper ones) to determine the shape of the Earth and find themselves in the awkward situation of proving conclusively that the Earth is a globe. So instead of learning from their experiments, they start thinking about how they can dismiss them.

Try watching some videos by people who actually read up on it pal, Like Scott manley, Vintage space or Curious droid. Because this is shit in comparison

 

[Burndown]

Just think the extent of secrecy that would have to exist around the world to hide something like Flat Earth. The thousands of people that work for NASA, the thousands of people that work for privately funded space programs around the world, all governments, anyone that has ever been to the poles, anyone that has been on a flight traversing the southern hemisphere etc etc etc

Anyone who believes flat earth - just take a moment and comprehend the impossibility of all of those people keeping this hush hush.

But most importantly, on the off chance you're right and all these people are successfully keeping this a secret - for what and who's benefit?

Yes that’s it. It’s very cleverly interspersed with psychologists and scientists explaining the reasons why people believe in mental stuff like this but it’s also a really interesting tale of the belief’s self appointed leaders. 100% watch it though, it’s really well done. Makes you really feel for some of the people who believe in it

True, hard to decide. It makes a good debate over a pint. Far better to debate two very positive things, rather than who is the least useless out of Corbyn & May.
