Looks Like OU Senior Member Avalon Has DONE IT! New Video!

Here is something I have never seen mentioned.  Since the moon has no atmosphere (just a vacuum)
WHY aren't the space suits PUFFED UP as hard as a FOOTBALL?  Nobody has ever pointed that out!

Like everything related to Apollo, another engineering marvel with an interesting beginning, spacesuits:

Tinman,

Have a look at this jpg:

From the Wiki page: https://en.wikipedia.org/wiki/Lunar_Roving_Vehicle

"The LRVs experienced some minor problems. The rear fender extension on the Apollo 16 LRV was lost during the mission's second extra-vehicular activity (EVA) at station 8 when John Young bumped into it while going to assist Charles Duke. The dust thrown up from the wheel covered the crew, the console, and the communications equipment. High battery temperatures and resulting high power consumption ensued. No repair attempt was mentioned.

The fender extension on the Apollo 17 LRV broke when accidentally bumped by Eugene Cernan with a hammer handle. Cernan and Schmitt taped the extension back in place, but due to the dusty surfaces, the tape did not adhere and the extension was lost after about one hour of driving, causing the astronauts to be covered with dust. For their second EVA, a replacement "fender" was made with some EVA maps, duct tape, and a pair of clamps from inside the Lunar Module that were nominally intended for the moveable overhead light. This repair was later undone so that the clamps could be taken inside for the return launch. The maps were brought back to Earth and are now on display at the National Air and Space Museum. The abrasion from the dust is evident on some portions of the makeshift fender."

Cool video showing how the rover was constructed:

The rovers, like every other aspect of Apollo, were engineering marvels.

Imagine breaking down further than your life support would sustain a walk back to the LEM.

I know exactly how the wheels were designed and built,as i have been studying this subject for some years now.

What you need to understand PW,is that i was a true believer in the moon mission's. But since i have been in the FE community,things have changed. We are taught to (when extraordinary claims are made) look and analyze everything very carefully --by people like your self. When you do this with the information supplied by NASA in regards to the moon mission's,then you start to see things that do not add up. By the way you are going about things here,i would say that you are one of those that need to believe in the moon landing's,and all common sense and analysis on your behalf is set aside.

This wheel design would gather up the lunar soil and then throw it out on the trailing edge.  When stopped, the soil captured inside the mesh would settle to the bottom of the wheel.  When first starting out or when moving very slowly the rover would indeed leave tracks.  Most times, however, these wheels picked up and threw out so much soil they tended to cover their tracks.

Really.
If we go about this the scientific way,then that reasoning is flawed beyond belief. We know that the lunar surface on the light side of the moon is consistent as far as the soil go's,as there is no other environmental impact's that could cause differing soil consistencies. We also know that the rovers are close to the same area around the lunar lander,which further confirms the consistencies of the lunar surface.

Now we come to the pictures below from NASA,and in these pictures we see no such wheel track consistencies. We see the reasoning you put forth as to the !!no wheel tracks!! claim is very inconsistent with the supplied data by NASA. Using the same means of investigation as we do here,as in studying the supplied data,we can clearly see that there is something amiss here,and that that supplied data tells us without doubt that the claim is false. When we look at the pictures below,we can accurately assume that the rover track's were made at different speed's in the different pictures. Some where the rover was slowing to a halt,and some where the rover was moving at a decent speed. So from all this information,we can conclude that the reasoning you supplied as to why there is no track's is incorrect.

The rovers, like every other aspect of Apollo, were engineering marvels.

The only reason they are considered to be !!engineering marvels!!,was because they were associated with the moon mission's. Other than that,they are nothing special,and given the over rated price tag on them,i (and many others here) could build twice the machine on half the budget.

We know the soil/dirt/dust (what ever you like to call it) on the moon would be as dry as a pub with no beer,as we all know's what happens to water when placed in a total vacuum. NASA says the temperatures on the moon's surface also reach over 200*F in sun light. NASA also used a dry sandy environment like the desert dunes to test there lunar rover model's,as they believed that this would closely represent the lunar surface. So let's take a look at the picture below once again. Look at how well the lunar soil holds itself together,so as to leave perfect footprints and wheel track's-->have you ever seen dry sand that will do this?. Foot prints with vertical walls of dry soil that dose not collapse.
Looking at the below picture,and many others,it would seem that the soil is moist-or would have to be moist to hold the imprints made. A great experiment would be to see if you can make a perfect footprint in very dry soil/sand/dust.

@ PW

So now we take even a closer look at the lunar rover wheels.
We know the lunar surface is dry dusty like soil due to not only the vacuum,but also described as such by the astronaut's them self.

So looking at the blown up picture below(compliments of NASA them self),can you explain as to why the !!dry dusty soil!! is sticking to all parts of the rovers wheels . Use your known science to explain this,and also carry out your own experiments to see if you can get dry dust/soil to stick to both the vertical and under side of a wheel.-->Remember,dry dust/soil,that is void of any moisture contents at all.

Tinman,

Apparently you "need" to believe that NASA did not go the moon.

First it was the radiation, then it was the absence of rover tracks, then it is why the tracks are there when maneuvering with its 4 wheel steering, going slow, or traversing possibly different soil types, then it was why do the sharper, non-weathered particles of the lunar dust in a vacuum and less gravity clump differently than rounded, weathered dust particles here on Earth with its atmosphere and greater gravity, then it was why do those very fine dust particles clump to possibly lubricant contaminated wheels.  The list will just go on and on, it never ends.  It is a silly game I do not wish to play. 

Yes, I believe man went to the moon,  I do not "need" to believe man went to the moon, I do so based on the evidence, the science and the engineering accomplished..  It was a tremendous accomplishment that required a huge amount of science, engineering, personnel, and guts to pull off.  The science and engineering required for everything related to human spaceflight was, and is, just amazing.

For you to say that you could build twice the machine on half the budget says a lot about your "beliefs".  I have always enjoyed your experimentation and willingness to share, but do you seriously believe yourself to be qualified to design, engineer, and test a human spaceflight rated lunar rover?  Anything rated for human spaceflight operating in the environment of space and on the lunar surface requires a great deal of science, engineering, and testing.  Although there are modern components available to ease the task, you would need a team of engineers just to design your rover, and suitable clean rooms, shake and bake and vacuum facilities to build, test, and certify it.     

The rover was much more than just a glorified Earth bound electric dune buggy or sand rail...
