Water on Mars!

"There is water on Mars." Double sharp (talk) 04:05, 30 September 2012 (UTC)

Croatian writer Giancarlo Kravar: Water on Mars! Discovered by NASA rover Curiosity. After a seven-week mission to Mars, Curiosity sent photos that reliably prove that on the planet used to bring water. Scientists estimate that the Curiosity even discovered a network of ancient riverbeds. Croatian daily Večernji list published a photo showing that the Martian surface once the river flowed.78.2.86.100 (talk) 03:12, 30 September 2012 (UTC)

Isn't this 15th or 20th time water (or past water) has been discovered on Mars? --Volcanopele (talk) 03:22, 30 September 2012 (UTC)

The Water on Mars article gives a large number of past findings of past water on Mars. Finding present water on Mars would be much more interesting. Double sharp (talk) 04:05, 30 September 2012 (UTC)

what is the company name of mars? — Preceding unsigned comment added by 108.249.142.62 (talk) 22:15, 12 October 2012 (UTC)

Mars, Incorporated of course. --RacerX¹¹ Talk to me^{Stalk me} 22:25, 12 October 2012 (UTC)

Edit request on 18 October 2012

Mars was created by penguins in the early 1940s because of all the Eskimo raptors that hunted them. Too many penguin were dying because of the Eskimo raptors that the realized there has to be someplace new and safer. The penguins did what they could to fight off the Eskimo raptors while they thought of how to solve their problems. Many penguins were dying but the remaining survivors built a rocket made out of ice footballs. Barren2134 (talk) 05:35, 18 October 2012 (UTC)

 Not done: Do you have any reliable sources to support this claim? Please note that many terrestrial observations have detected Mars before the early 1940s. Double sharp (talk) 05:47, 18 October 2012 (UTC)

Please Convert

All the atmospheric pressure data in the atmosphere section is given in kPA. Since this is an encyclopedia, we need English measurements so that it is meaningful and comprehensible to the layman. Someone needs to convert these pressures into PSI, ditto for the thicknesses of the ice sheets (need to be converted to feet/yards.) and add the standard customary figures to the metric ones.198.229.211.94 (talk) 04:38, 29 October 2012 (UTC)

The article as written meets the WP standard form for scientific articles. See WP:UNIT. DanHobley (talk) 13:24, 29 October 2012 (UTC)

Temperature

This sentence has been around for a long time: "The summer temperatures in the south can reach up to 30 °C (54.0 °F) warmer than the equivalent summer temperatures in the north". I have tried to edit it but my edits are rejected. To be clear, 30 Celsius is 86 F. Not 54. The 54 is a typo. — Preceding unsigned comment added by Marleymanbob (talk • contribs) 16:48, 02 November 2012 (UTC)

Thirty degrees warmer isn't the same as just 30 degrees. The sentence isn't expressing a temperature but rather a temperature differential. Think about it this way: the difference between 0 degrees centrigrade and 30 degrees centigrade is 30 degrees. Convert those figures to Fahrenheit and you get 32 and 86—a difference of 54 degrees. Rivertorch (talk) 17:18, 2 November 2012 (UTC)

Converting a temperature difference on Mars to °F is inherently confusing and pointless. Why don't we just put it in K? Dicklyon (talk) 17:59, 2 November 2012 (UTC)

That occurred to me, too, but I suspect that most readers would need to go to kelvin for it to be meaningful to them. I suppose we might express the difference as 30 K and then put both 30° C and 54.0° F in parentheses. Rivertorch (talk) 18:52, 2 November 2012 (UTC)

Guys, bear in mind WP:UNITS. General policy says we should generally only be using standard scientific units. I'd say that's K. Fahrenheit definitely not needed in this context. DanHobley (talk) 19:48, 2 November 2012 (UTC)

Hmm . . . yes. It should have occurred to me that the MOS says something relevant about this. I was thinking in terms of providing content that readers like me with nonscientific backgrounds might be able to decipher without consulting a second article. There are other subject areas where my attitude would be Let 'em go to the other article and learn something new, and I suppose there's no reason to be inconsistent now that the shoe is on the other foot. By all means, let it be kelvins and kelvins alone. Rivertorch (talk) 23:04, 2 November 2012 (UTC)

Request for edit - temperature values are have incorrect conversions

The summer temperatures in the south can reach up to 30 °C (54.0 °F) warmer than the equivalent summer temperatures in the north.[134]

30°C is 86°F and 54°F is 12.2°C. I would guess that the 12.2°C/54°F is the correct value, but I cannot access the article referenced in the foot note Smoidel (talk) 16:32, 4 November 2012 (UTC) S Moidel 11-4-12

No, that's incorrect. Please read the preceding section. I believe the question has been resolved. Rivertorch (talk) 17:01, 4 November 2012 (UTC)

Yes Rivertorch, the statement is expessing a difference in temperature, which as also pointed out above is indeed confusing. So the coversion is correct, but on a side note, what about the statement itself? Can anyone confirm that there is that big of difference between the two hemispheres?--RacerX¹¹ Talk to me^{Stalk me} 17:11, 4 November 2012 (UTC)

Confirm it how? Do we need another source? Rivertorch (talk) 17:22, 4 November 2012 (UTC)

Maybe I used the wrong wording. I may be just repeatedly overlooking it but where in Goodman source does it state the difference between the northern and southern summer highs? --RacerX¹¹ Talk to me^{Stalk me} 17:49, 4 November 2012 (UTC)

Nevermind, just found it. sorry. --RacerX¹¹ Talk to me^{Stalk me} 17:54, 4 November 2012 (UTC)

A subpage really should be linked for that ref. Sorry, I saw that the other day and had forgotten. It needs to be checked whether the other instance(s) that use the same refname are supported by the same or different pages. If they all refer to that page, then the citation url can simply be fixed. Otherwise, it would mean different refnames (i.e., different citations). If I have a spare moment I'll check it, but not today. Rivertorch (talk) 19:00, 4 November 2012 (UTC)

INTERNAL STRUCTURE

This fails to mention the hydrogen in the Martian interior. The December 1, 2012 issue of Earth and Planetary Science Letters will publish the finding of scientists Conel Alexander and Jianhua Wang, who studied Martian metorites. It is important that the Wiki page on the internal structure of Mars reflect that Earth and Mars formed from similar sources and that they have chondritic meteorites as their sources of water. — Preceding unsigned comment added by 35.0.87.254 (talk • contribs) 4 December 2012

Not done for now: This is not an absolute "no" response to your request, but you need to provide the following:

• The exact text you want placed into the article
• If possible, an internet location where the proposed source can be found

If the subject of this edit is controversial, there also needs to be a consensus among multiple editors that the proposed edit is acceptable. —KuyaBriBri^Talk 23:20, 4 December 2012 (UTC)

"Martian" vs. "martian"

The term "Martian" is (correctly) capitalized in most locations in the article, but the incorrect version "martian" appears. Please fix, thank you.

Fixed, thanks. Materialscientist (talk) 03:18, 16 December 2012 (UTC)

Dead link

The ref with this url has a dead lnk: http://mpfwww.jpl.nasa.gov/mgs/newsroom/20050920a.html -- FutureTrillionaire (talk) 05:35, 8 January 2013 (UTC)

I can't find it. What ref is it currently (or what text does it follow)? Rivertorch (talk) 08:10, 8 January 2013 (UTC)

I found it, "Orbiter's Long Life Helps Scientists Track Changes on Mars", currently ref 22. This should be the updated link, but I find it rather vague to state that the southern ice cap "have been receding" based on a source which claims that CO2 deposites near the south pole was receding for a period of three years (which is now appr ten years ago).
