Mars Water
Thanks FieryIce. and Norval. I came across this picture the other day and it had me thinking. I still think I am on the right track. http://www.msss.com/mars_images/moc/publicresults/2005/11/S12-00015p.gif Craterchains may find this interesting too if he has not seen it already. The marks I see on t...

Hi Just had a look at FieryIce's- last post and the reference to Newton Crater. http://antwrp.gsfc.nasa.gov/apod/ap000626.html Great picture. Just have a close look at rocks which protrude on the face of the feature and which way the sheltered debris tails point. There is evidence of down flow in th...

Hi Happy new year folks I have had a look at another posting by Aqua and a further post by Craterchains and I hope you both dont mind if I post the link by Craterchains http://www.msss.com/mars_images/moc/2005/10/27/index.html This particular picture is very interesting although it may not be of muc...

Hi Harry Does anyone drink that stuff :wink: I had a look at a couple of interesting sites last night about Saturns moons- I knew of Promethius and its thieving qualities but did not know about Ensiladus and its atmosphere-lean. I am not sure of the orientation of its "Tail" but I presume ...

Hi Nice pictures. Nice to know Craterchains and Fieryice are on a similar frequency. Thanks for the polar picture posting Harry. The polar ice almost seems to have a circumpolar flow mmmmmmmm. This is an interesting link to Noachin pit craters and a boulder deposit in one of the pits Top right hand ...

Hi Norval and FieryIce your posts are interesting. Do I understand you suggesting there may be a abrasive action of coarse sand particles that has and is making the observed damage and that it may be a presently ongoing process.- I suppose it could account for upward flow in some cases mmmm I still ...

Hi My best guess would be to look to the Hellas impact basin as the cause for the planet wide vaporization of any water that was there. The lower gravity on Mars would then add to the effect of Loss to space. Yes the impact which created the Hellas crater is most impressive and you may be correct. P...

Hi The link was interesting re water found Dan. I suppose it still lines up with being the remainder of the water after most had been taken. Consider the process of the water being removed from the spike and ending up as an elongated shape which at some point would break and leave elongated sections...

Hi A bit of a flurry of answers there- thanks for the replies and thanks for the photos Norval I will have a study of these. Could I just take a line from Dan >This does explain where all the water came from, quite conveniently. It >also does explain, why no water on Mars now. We only haven't figure...

Hi Folks Just a thought re a couple of lines about how recent water flow on Mars and temperature and pressure. I am still hanging on to my initial theory and adding a little more. If most of the water was taken by a gravity source and the remaining water reset--found its levels- the rivulets on the ...

Hi When you look at pictures of mars please keep the upward flow in mind. Note the main damage seems to be in an upward direction southfacing outcrops with tails going upwards the northern plains "Resurfaced" Eliptical orbit Main high flow damage between 30 and 70 degrees South If water di...

Hi agaid S Bilderback I seem to have missed one of your posts- I am sorry. I am not sure you are bringing up the same picture as me but http://mars.jpl.nasa.gov/mgs/msss/camera/images/june2000/newton/newton_figure2_5.4.jpg This should show part of a crater rim with rivulet markings going down from b...

Hi S Bilderback Thanks for the post. I do see your point in the post but please consider http://www.enchantedlearning.com/subjects/astronomy/planets/mars/ Mars---- Its orbit is very elliptical; Mars has the highest orbital eccentricity of any planet in our Solar System except Pluto. Also please cons...

Hi Norval
Interesting thought. It is said the water movement on Mars looks recent and I presume you may be refering to the same gravity source with a much milder effect on Earth.

Hi Doum. Just lost a post-- I will try again. Yes you could be right-- but considering some of the tidal streams on earth with speed and height it is still worth considering. The tidal bulge in the northern hemisphere would have been large and deep and not so rounded at its peak due to the exponenti...

http://mars.jpl.nasa.gov/mgs/msss/camera/images/june2000/newton/newton_figure2_5.4.jpg This would seem to be a good picture to illustrate my point. To the right the terrain features perhaps show a large uphill flow causing some impressive errosion-- Look at the shape of the terrain above almost all ...

Hi Norval You caught me out a little here re pictures and links because I have not thought about this for a year but here is part of an article and a link re Mars. >>>The channels are also inclined downstream, which is typical of ice flows that can push up inclines. Such gouge marks are unlikely to ...

Hi I suppose this subject has been well and truly thrashed but this may not have been considered. Imagine Mars as a well covered planet with lots of water-- earth like possibly. An approaching scource of gravity begins to have large tidal effects which become greater and greater as the gravity scour...
