Outdated sources

[edit]

In the future, when quoting primary sources, please verify they are current theories or models. Not because they have been published it has to be included (example: Flat Earth model). In this particular subject, a wave of speculations were proposed and published, and the latest research all points at cold geyser-like or jet-like systems. Most old theories were discarded on basis of thermal imaging. Note that current geophysical models deal with the most likely geyser mechanisms, of which there is no consensus yet. I know the Hungarians propose the thingie is alive, so it is listed apart. If you come across new papers citing a phenomenon different than geyser/jet/outflow/eruption/plumes, etc., please go ahead and post it here or intregrate it to the article.

Geysers on Triton

[edit]

There are similar markings in the southern subpolar region of Triton [50° and 57°S] (observed by the the Voyager 2 probe in 1989) which are ascribed to geysers powered by subsurface vaporization of nitrogen. It would be useful to compare and contrast these with the ones on Mars.--Tediouspedant (talk) 14:09, 23 October 2009 (UTC)[reply]

I read that both models are similar but I have not read anything about the ones in Triton. The ones in Mars happen on ice no thicker than 1 meter and use solar energy to sublimate the ice. The ones in Triton seem powered by powerful geological processes as the plumes are several kilometers high. I think writting a short section comparing them would be interesting, especially if the mechanism are thought to be similar. Cheers, BatteryIncluded (talk) 20:09, 23 October 2009 (UTC)[reply]

Are there any actual observations of the Martian 'geysers' themselves?

[edit]

WP seems to have a habit of making 'hypothetical' / 'theoretical' things sound far too 'settled' for comfort.

There seems to be a lot of speculation going on in the literature as to how the dark spots form and how the dark fans form. The literature seems caught up in the current 'geyser' model.

Do we have any actual DIRECT evidence of this (visual confirmation, etc.), or is it all strictly hypothetical at this point? If so, that should maybe be made more clear in the article.

I assume a geyser is probably too small a feature for even HiRISE to successfully image at sufficient resolution? So, I'm not holding out much hope on that score...

There seem to be a few problems with the geyser model & the "spiders." For one, is there any specific reason for the formation of filamentary channels in the terrain? As opposed to say big circular pits or some other morphology? We know that frost layers come and go in other regions and that dark spots and fans form on and around areas where NO spiders are seen. Why aren't spiders/geysers seen in THOSE regions? Do we see 'spiders'/'geysers' in the northern latitudes as well? If not, why not? Why do 'spiders' / 'geysers' only occur in specific areas of the southern latitudes? One assumes the same laws of physics / chemistry apply in both hemispheres...

Is there anything in the literature WRT problems with the geyser model? Perhaps that should be included for balance, if so? 'Open questions,' 'unsolved contradictions,' etc. 50.53.113.32 (talk) 04:26, 4 December 2012 (UTC)[reply]

All your answers are in the article. Including:
  • From the introduction: "There is no direct data on these features other than images taken in the visible and infrared spectra."
  • "Time-lapsed imagery performed by NASA confirms the apparent ejection of dark material following the radial growth of spider channels in the ice.[8] Time-lapsed imaging of a single area of interest also shows that small dark spots generally indicate the position of spider features not yet visible; it also shows that spots expand significantly, including dark fans emanating from some of the spots, which increase in prominence and develop clear directionality indicative of wind action."

Requested move 31 August 2017

[edit]
The following is a closed discussion of a requested move. Please do not modify it. Subsequent comments should be made in a new section on the talk page. Editors desiring to contest the closing decision should consider a move review. No further edits should be made to this section.

The result of the move request was: moved to alternate proposals. Andrewa (talk) 01:20, 24 September 2017 (UTC)[reply]


WP:NATURAL disambiguation is preferred to parenthetical, so the forms used in the articles' ledes are better choices here. I would also support Geysers on Mars and Gullies on Mars, or Geysers of Mars and Gullies of Mars. --BDD (talk) 15:01, 31 August 2017 (UTC) --Relisting. Steel1943 (talk) 16:52, 7 September 2017 (UTC)[reply]

Also support third option Geysers on Mars and Martian geyser below, or Geysers on Mars and Martian gully

The above discussion is preserved as an archive of a requested move. Please do not modify it. Subsequent comments should be made in a new section on this talk page or in a move review. No further edits should be made to this section.
