Giant Cross Seen In Curiosity Image

[The Matrix Traveller]

Wiring longevity doesnt matter if its in a soundstage right next to the control room. If something busts loose, they can make a quick fix while the live feed is "down".

What to look for if there are problems is, any change in wiretie positioning or wire harness locations before and after repairs are done in secret. Check all the imagery and see if any harnesses or wiring in general has moved or become different in appearance.

Any difference in appearance on the rover between scenes, will prove theres been human hands upon it, and seeing how there are no repair shops on Mars..itll give the evidence necesary to know its all a sham.

I wonder if we can discover this Scenario ? Far out, if this is found then What ?

Found even more information regarding external wiring and external surfaces and materials.

http://descanso.jpl.nasa.gov/SciTechBook/series3/04Chapter3SCDesign.pdf

Pages 46 through 49 deal with external wiring.  Still have not found anything dealing with the environment affect on the wiring externally.

Thanks again for all your efforts...

Neither have I.  Absolutely No discussion at all ! Very Strange. Perhaps it never came to mind ?

After some hours of searching last night, from a design and manufacturing perspective, what I see
in the Photos is shocking to say the very least.

Esp. when we have Wireless technology, often used today in the case of Wireless key boards,
Wireless Routers, Wireless Printers, Wireless headphones, Microphones, and the Wireless mouse etc.

Gets rid of unwanted Cables so the external wiring around our desk is kept to a minimum !

We don't see external wiring all over our PC, Laptop, Mac, or ipod, phones, TV's etc. etc.

Rockets and Aircraft don't have External Harnesses or Looms. All is kept inside the aircraft or Rocket.

Cars and other Transport keep most of their wiring inside as well.

I seriously wonder if their Standards comply with or meet ISO Standards of safety and Manufacture.

Does anyone have a reasonable explanation for why robots that operate outdoors in a potentially dusty and extreme, partly unknown, environment?  I can hold up my hands and say that I don't.

Bizarre.  It does reinforce the feeling that it is a big stage show.

If anyone can explain it, please do.  Would you really build a vehicle with robotic arms to operate in a desert like environment like that?

[ArMaP]

So write NASA and ask them why they left them exposed like amateurs and what material they used

Done.

I hope I am as lucky as in other occasions and that I get an answer.

Here's a link to a pdf file that gives some insight on the effects of solar radiation on different materials
here on earth.

Good read for others there mikeybandb...

This is generally known within Manufacturing, when using these materials.

Could have an accelerated problem with this on Mars.

So very, very Strange why wiring is external and Not shielded (kept internally) out of this environment not to mention dust contamination around hydraulics, electric solenoids and actuators etc..   

We need to know far more, about the Mars environment, regarding Solar radiation and Cosmic radiation.
We also need to know more, about radiation regarding the natural terrain on Mars i.e. what radioactivity is present in natural terrain raw deposits etc.

What is the make up of Mars's Magnetic fields?
Is there an ozone layer (need O2 to be converted to O3) if there were, it would be very insignificant if in fact Ozone is present in its Atmosphere.

The energy in UV, is usually reduced through the Manufacture of Ozone in our upper atmosphere.

Ozone can't be "store" in the atmosphere !  It has to be manufactured on sight, in this case in 03 being produced predominantly through the exposure of O2 by U.V.
Some (little) is also produced through electrical discharge.

It is this natural process which reduces the energy levels of U.V. Radiation on the way to the Earth's surface.

(If polymers come in contact with Ozone depending on the levels above 15 pts/million, degradation of many polymers can become very rapid.
(Unwanted Ozone is also produced on the surface of the earth, through the impact of industrial practices.))

So I suspect the impact of U.V. on Mars could be at least the same as on Earth as Mars is further from the Sun, if not higher lacking protection from UV, so the insulation on wiring esp. involving degradation of polymers could, I suspect be a problem, as many materials contain oxides.

So why expose insulation of wiring unnecessarily ? Esp. to this harsh environment involving Radiation and dust !

It involves more construction to have wiring exposed in this way.

What is the affect of these harsh conditions, on "through panel Grommets" etc. to prevent chafing of wiring insulation and possible electrical short-outs.

The flexing of insulation (involving polymers) under these conditions, i.e around joints in robotics and turrets etc could also present a serious threat to their missions.

I found this page of "CABLE AND HARNESS GENERAL REQUIREMENTS".

It looks like that's an old site, replaced by the NASA Electronic Parts and Packaging (NEPP) Program.

I also found this, so it looks like the wiring uses "DUNMORE Corporation's high-performance thin films".

I haven't got an answer to my email yet.

Re. http://www.bus-ex.com/article/dunmore-protects-mars-rover-curiosity

NASA's Jet Propulsion Laboratory used a special reinforced tape created by DUNMORE to insulate all of the wiring inside the Mars rover. The insulating tape ensures the electrical currents from the rover's different systems don't interfere with each other and impede the rover's operation.

DUNMORE created the tape by combining DuPont™ Kapton® polyimide film with a 3M adhesive and fiberglass reinforcement layer. TheDUNMORE tape is the only multi-layer insulation (MLI) product on the Mars Rover.

ensures the electrical currents from the rover's different systems don't interfere with each

Ah sounds like "Shielded" cable.

But the cable on the Outside, appears to be non-shielded looking at the photos !

3M is an old and well established Company, who manufacture in their product range, adhesive tape with fiber reinforcing.

Have used Tons in the past, (no longer have records, re. weight) of these products in Manufacturing.

polyimide film...
http://www.3m.com/product/information/Polyimide-Film-Electrical-Tape.html

http://www.kaptontape.com/

Commonly used in Solenoid, actuators and transformer Manufacture etc. etc. nothing special.   

And the "external" wiring ? (Not mentioned)

Why have External wiring in the first ? (built in "Product Redundancy" technology ?    )

And just costs more to manufacture !

But that probably doesn't matter when using Taxpayers $$$$$$   

How many vehicles on Earth, TV's, Computers iphones, ipods and other electrical products are covered in external wiring ?

We have advanced, to using "Wireless" accessories today... 

[mikeybandb]

This is interesting...

I don't trust wireless.

Also, could it be possible that wireless would be more likely to be affected by radiation?

Good point. This is why we need to know and understand more about the "environment" of Mars, and Not take anything for granted !
