What kind of "extraordinary feats" are you looking for? Jumping high? They did that. Armstrong jumped up from the ground to the third step of the LM
ladder. That's about 5 to 6 feet. He also stated that there was a tendancy to tip over backwards (due to the PLSS on the back) and decided that it
wasn't worth risking ones life. An astronaut on a different mission (I forget which one at the moment) did some free standing jumps. He got up to
about 4 feet, but again, due to the PLSS on his back which affects ones center of mass. He tipped over and landed on his back. He was very lucky that
no damage happened to his PLSS.
Also, astronauts weighed more than 180lbs. With a fully loaded space suit they were about 300lbs which is about 50lbs on the Moon. And don't forget
that they still have 300lbs of mass
regardless of the amount of gravity. And when you're comparing how high some one jumps on Earth to that of
the astronauts on the Moon. Are you comparing it to some one wearing the same space suit on Earth? It would only be fair, since those suits are heavy,
bulky and stiff.
With 1/6th gravity, the dust plumes should have gone some 60 feet high and floated off behind for a considerable distance, but they’re less
than 10 feet high and hit the surface almost immediately! And dust ‘waves’ produced in the wake of the buggy can only be produced in an
environment having an atmosphere!
What leads you to believe that the plumes should have been 60 feet high? What calculations lead you to that conclusion?
The fact that the dust returned to the ground shows that there is indeed no atmosphere (or not enough of one) to affect the particles of dust. If
there were an atmosphere, the dust would have remained suspended in it, like it would on Earth. But it all falls with no atmospheric resistance. The
dust "waves" have nothing to do with an atmosphere. They're caused by the rover bouncing up and down as it drives over the bumpy surface.
You can clearly see that the rover is bouncing as it's moving and the tires kick up more dust when they dig into the ground more, creating "waves".
Have you ever witnessed a car driving down a dirt road? The dust clouds and billows and remains suspended in the air for a while. It looks nothing
like what's shown in the video of the Rover.
It would have been impossible to have a water cooled space suit on the Moon, when outside temperature was already at boiling point of water,
there would be no where for the heat to dissipate. But water cooled suits are a viable proposition in an environment where atmosphere is
Wow... where to begin...
When you say the outside temperature is already at the boiling point of water. What are you referring to exactly? Surely not the vacuum of space,
which has no temperature. Were you referring to the surface
temperature Moon? If so, how does surface effect the water cooled suits?
The water cooled suits worked by sublimation. The water in the suit is allowed to seep through a pourus metal plate into the vacuum of space, where it
freezes onto some coils of tubing. Water that's pumped through the coils is cooled by the ice and the ice sublimates (going directly from a solid to
a gas) into the vacuum of space, taking the heat away with it.
This method of cooling is a space standard. To deny that the Apollo water cooling system doesn't work. You'd also have to be denying that Russian
space suits, the MIR space station, the Space Shuttle and any other vehicle that uses this cooling method, ever worked.
Anyway, my time is limited, I'll leave it at that for now.
