Re: I See Twisted Ropes
O Michael Goodspeed! (is how EU people should say OMG!)
i have seen some EU things in my time but that is either one of the most amazing, or, even more proof and evidence for water on Mars ...
any more on where and what?

Re: I See Twisted Ropes
Here are some anaglyph close-ups of the crater. Cyan/blue 3D glasses required. I tried to use the gray-scale images but the depressions kept becoming mounds in my mind. If anyone wants to check the large gray-scale, look here -- WARNING 206 megabyte image:

Top center near the crater wall.
Close-up 2
Fulgurites embedded in the crater cliff edges; polygonal formations cut into the rock; fractal scaling; etc. Electrical scarring evidence.

I noticed a twisted rope effect on New Horizon's images of Pluto ...zoom in on the areas running south from the "Icy Mountains" ...

Gravity on Mars
Does anyone have any info, or links, relating to the measured versus predicted gravity on Mars.
Given that gravity in the current model relies on mass, i am wondering if there is a discrepancy between prediction and measurements by the various landers (if they had such a sensor on board). And if so, by what percentage they two were different.
Thx in advance - Trevor

Re: Gravity on Mars
I do not think there would be much discrepancy, the charge effects become greater the smaller the body, i think mainstream is accurate about the gravity on Mars.
I searched and i think MRO did some measurements but about gravity anomalies > http://www.hou.usra.edu/meetings/lpsc2014/pdf/2479.pdf
not much data...

Daniel

Re: Gravity on Mars
Thanks Daniel.
Thx for the link.
You're right, there isn't a lot of data on the subject.

Re: Gravity on Mars
Should be very easy to test gravity on Mars since it's a downward push. Transport a bathroom scale to Mars with a known weight on top and compare the difference. Much more complicated than that but that's the concept.

Phobos & Deimos orbits identify the strength of gravity on Mars.

Re: Gravity on Mars
Perhaps, but I don't think gravity is the only force that determines orbital path. Electromagnetism must play, at minimum, a repulsive role, but also, it likely plays an attractive role as well.Aardwolf wrote:Phobos & Deimos orbits identify the strength of gravity on Mars.
Thus the need for measurement

Re: Gravity on Mars
The smaller the body the bigger role E/M plays.
Gravity influence diminishes with radius getting smaller
So yes Phobos and Deimos have their orbits also thanks to electrical interactions.

Daniel

Re: Gravity on Mars
Their densities calculate so low, that it is speculated that they are porous, or hollow.Aardwolf wrote:Phobos & Deimos orbits identify the strength of gravity on Mars.
My speculation is that there is something missing from their gravity calculations.
Looking for a reference, I found
From Space.com info page on Phobos
Ah, here we go... from the ESA info page on Deimos.The moon is so small that a 150-pound person standing on its surface would weigh only two ounces.
Mass: 1.0659 x 10^16 kg
Density: 1.872 g/cm^3
Density is 1.7 gm/cm^3Despite remote sensing investigation by Mars Express, Mars Reconnaissance Observer and Mars Global Surveyor, the composition of Deimos has not been resolved. The composition is a key indicator in the search for the origins of Deimos and Phobos. Data from the Mars Express OMEGA spectrometer suggest that Deimos has a primitive composition. Like Phobos, Deimos is thought to be quite porous.
Mass: 1.5 × 1015 kg
ESA page didn't have the density.

Re: Gravity on Mars
I agree the density calculations and mass as the unique driver of gravity is questionable, but the OP query was merely asking if gravity had been measured and it has using its moons. The mass of the moons are irrelevant with respect to measuring Mars gravity.comingfrom wrote:Their densities calculate so low, that it is speculated that they are porous, or hollow.Aardwolf wrote:Phobos & Deimos orbits identify the strength of gravity on Mars.

Intersecting Channels near Olympica Fossae

I beg to differ.

Their explanation:What caused this array of various channels and intersecting pits?

Re: Mars - miscellaneous anomalies
crater on Mars while viewed on google maps (link >here<), unsure of its name, but it is found near the southern pole. my googling skills havent been up to finding a mainstream explanation

A "Carrington Event" hits Mars; "Steve" again

I hope the links work. If it doesn't then just go to Spaceweather.com and noodle around for it. You'll see it.

The other day "Steve" was sighted again. Same phenomenon complete with the twisted elements, and this time NASA even measured the increase in electrical activity. Do ya suppose it might be a Birkeland current? Of course it is. Maybe it needs to have a poster attached for NASA to get the message.
