Last week Nasa announced that Siding Spring will cause auroras in the Martian atmosphere. Quoting: BG-Fan
Several weeks ago McCanney said the same thing on his radio program
James Dimwit McCanney also said that ISON is bigger than Mars (was it?) and would change the orbit of Mars (did it?).
This seems to be an unprecedented statement from Nasa. No where in the history of their commentary of comets has this ever been stated. In fact, when Hally passed close to Earth in 1910 no such phenomenon was reported or even speculated. Quoting: BG-Fan
Earth went through the tail of Halley's Comet - it was never supposed to come in contact with its coma. In fact Halley was 22 million kilometers away at closest approach.
And yes according to standard theory they rely a great deal on magnetism while almost completely ignoring electrical conditions all together. So given that Mars basically has no magnetosphere, it makes the Martian aurora claim all the more fantastical from standard theory, doesn't it? Quoting: BG-Fan
Did you read the NASA article? Or do you just parrot the ThunderDolts?
"Unlike Earth, which has a global magnetic field that shields our entire planet, Mars has a patchwork of "magnetic umbrellas" that sprout out of the surface in hundreds of places all around the planet. If Martian auroras occur, they would appear in the canopies of these magnetic umbrellas.

Easy to research things - why don't you do it before you make a fool of yourself?
Uh-oh McCanney hot button. All hands on deck.
Looks like Nasa is parroting McCanney.
Yes, I read the article and posted about it on another thread last week. Got a great laugh out of the "magic umbrella" theory....lol
Still doesn't explain how a coma of gas and ice (per standard theory) will light up the atmosphere.
Where in that article does it say how these auroras will be "sparked"?
Here's another one for you all to chew on. I had mentioned the possibility of water falling on Mars from SS's tail on Astro's thread about SS a while back. I'm sure you remember.
Here's some tidbits from an article 3 days ago that speaks to the Mars orbiters and what they will be doing around the 19th of October.
"Oct 19 18:47-20:16: 2 CRISM and 4 HiRISE scans of the nucleus with CTX riding along. The comet will be roughly 300,000 kilometers away, so the images will have lower resolution than the close-approach ones by a factor of about two. The MCS and MARCI observations that follow the comet imaging are the ones most likely to show effects of the coma's interaction with Mars' atmosphere. These might include heating of the middle atmosphere due to dust flying into it. In response to that heating, the atmosphere should inflate, causing vertical motion within the atmosphere. And the increased amount of dust in the middle atmosphere could seed clouds that weren't there before.

Hmmm ... not sure exactly what they mean by dust could seed clouds that weren't there before. How does dust seed a cloud that isn't there?? Where did the clouds come from that they say the dust will seed? A little confusing and ambiguous, but perhaps alluding to a possible rain event (standard theory style??). In this case they got rather awkwardly out in front of McCanney, again. Don't know how else to say it.
I know recently (this year) NASA has said that water can enter Earths atmosphere in dust particles.
"Could Space Dust have Delivered Life’s Ingredients to Earth?
Feb. 6, 2014
"For the first time, scientists have detected water molecules on the surface of interplanetary dust particles. The water forms in tiny bubbles when solar wind irradiates and damages the dust grains floating through space."
"Previous research had shown that space dust also contains organic carbon—another key ingredient for life. Taken together, these findings raise the intriguing possibility that dust trickling down from space could have seeded life’s building blocks on our own planet—and potentially elsewhere."

FYI .... for future reference if you see no quotes then it's my words.
