Talk:Mars

Add mention of distance from Sun and amount of sunlight to first paragraph at top

Within in the article: Climate on Mars "The planet is 1.52 times as far from the Sun as Earth, resulting in just 43% of the amount of sunlight.[140][141]"

I think this is basic information that should be added to the end of the first intro paragraph at the top as well.

It could be restated in somewhat simpler form with a link to the Astronomical unit and Solar irradiance article:

Mars is about 1.5 times as far from the Sun as Earth is and receives 43% of the amount of sunlight. 24.143.105.91 (talk) 17:06, 28 July 2025 (UTC)

That's what the infobox is for. Remsense 🌈 论 02:51, 1 August 2025 (UTC)

Typo under Renewed Exploration?

Seems like theres a typo in the first paragraph under Renewed Exploration. "Until 1997 and after Viking 1 shut down in 1982, Mars was only visited by three unsuccessful probes, two flying passt without contact (Phobos 1, 1988; Mars Observer, 1993) and one (Phobos 2, 1989) malfunctioning in orbit before reaching its destination Phobos." Past seems to be misspelled. 160.3.200.88 (talk) 18:01, 14 September 2025 (UTC)

Inner core conundrum

So, currently there seem to be two different conclusions in the literature as to the presence of an inner core on Mars. Recently, this paper was published which suggests the existence of a solid inner core from seismic data. The problem is, the previous conclusion (and the one used in the diagram on this very page) was drawn from this paper, which claims the exact opposite. Neither group has acknowledged the other or their respective conclusions as far as I can tell, so my question is how should we proceed with this matter? The recent paper also contradicts the tentative detection of a molten silicate layer. Xiphosura^Talk∞Edits 07:21, 23 November 2025 (UTC)

Incorrect "literal" quotation

Change:

"if water vapor or oxygen occur in the atmosphere of Mars it is in quantities too small to be detected by spectroscopes then available"

to:

"if water vapor or oxygen occur in the atmosphere of Mars it is in quantities too small to have been detected by spectroscopes then available"

That is the correct quote from the original source.

Time of Perihelion Outdated

I am pretty sure the last perihelion was on the 26th of March, 2026, not in 2022 AerospaceloverVC-25A (talk) 22:34, 18 April 2026 (UTC)
