2012 Speculation - detection of organics ?
editDeleted speculation on organics finding. NASA Plays Down Mars Speculation BatteryIncluded (talk) 15:23, 30 November 2012 (UTC)
media hype and the exact organics
edit[pp1] It was planned to use a fine grained sand most likely a dune to to clean out contamination from the sample scoop and the inlet system of Chemin and SAM. Rocknest was chosen to be this sand. X Scoops were taken and discarged. the following Y scoopes were analyses by the two rover internal instruments Chemnmin and SAM.
[pp2] On October 17, 2012 at Rocknest, the first X-ray diffraction analysis of Martian soil was performed. The results revealed the presence of several minerals, including feldspar, pyroxenes and olivine, and suggested that the Martian soil in the sample was similar to the weathered basaltic soils of Hawaiian volcanoes. The sample used is composed of dust distributed from global dust storms and local fine sand. So far, the materials Curiosity has analyzed are consistent with the initial ideas of deposits in Gale Crater recording a transition through time form a wet to dry environment.[78]
[pp3] In the following days 3 measurements with the SAM instrument were done. The relative complex nature of the instrument and data analysis delayed the publication of first results in the weekly press conferences. Rumors were fueled by an interview of the project scientist John Grotzinger and later by an interview of the director of JPL Charles Elachi.
[pp4] On November 22, 2012, the Curiosity rover analyzed a rock named "Rocknest 3" with the APXS and then resumed traveling toward "Point Lake" overlook on its way to Glenelg Intrique. On December 3, 2012, NASA reported that Curiosity performed its first extensive soil analysis, revealing the presence of water molecules, sulfur and chlorine in the Martian soil. The presence of perchlorates in the sample seems highly likely also the presence of sulfate and sulfide is likely because sulfur dioxide and hydrogen sulfide were detected. Small amounts of chloromethane dichloromethane and trichloromethane have been found. The source of the carbon in the mentioned molecules is unclear until now. Contamination of the instrument, organics in the sample and inorganic carbon like carbonates could be possible sources.
Should we change it to more like that?

- OK - added last sentences of noted [pp4] above to article (w/ some mods and wls & refs adds) re exact organics detected as follows =>

Spectral Analysis (SAM)
editOne EGA-plot is labeled as "Spectral Analysis (SAM)". Most people working with that type of plots avoid the spectrum word and use th word plot to avoid the question on "Where is the wavelength axis?" --Stone (talk) 20:06, 27 April 2014 (UTC)

cruise phase problem?
editShould the center of navigation problem written in "The Right Kind Of Crazy" be included? If so, what kind of links or citations should we add? I couldn't find a PDF version of the book online. Weijia Yu (talk) 12:36, 23 January 2017 (UTC)

editShould planned future events be covered here, or where ? eg. Here is planned route : Curiosity's Proposed Path up Mount Sharp NASA May 2019 - Rod57 (talk) 09:49, 22 July 2020 (UTC)
Reorganizing Subheadings
editCurrently, the timeline is organized with yearly subheadings, i.e:
2012
[2012 events here]
2013
[2013 events here]
2014
[2014 events here]
...and so on.
The MSL mission can be broken up into a Prime Mission (2012-September 2014)(link to verify end of mission), First Extended Mission (Sep. 2014-Sep. 2016)(link to verify end of mission), Second Extended Mission (Sep. 2016-Oct. 2019) (link to verify end of mission), Third Extended Mission (Oct. 2019-Apr. 2022)(link to verify end of mission), and now the Fourth Extended Mission (Apr. 2022-Present).
I think it would be better for this article to be organized according to these missions rather than the year. Missions will be more thematically cohesive than years. Also, since this rover gets less attention these days, each of the yearly subheadings in later years is a stub.
Since this is a major structural change, I figured I should seek consensus first. (While major, it is an easy change - since I know the dates each mission started, all currently-written text would be preserved and just the locations/names of the headings would change)
AlliterativeAnchovies (talk) 17:46, 28 April 2022 (UTC)
- It did not make sense to me for us to have a heading for every year now, given that each heading in recent years contained very little information. Thus, I have re-grouped the page to be based around the extended missions instead. These can be grouped around a theme, so it makes sense to do so as well.
- Given that I proposed this change a year ago, and there were no complaints then, I hope this will be alright now.

Major changes to improve quality
editI am about to make several large edits to this article. They include the following changes:
1) Removing the build up of images, justified by MOS:IMAGELOC and MOS:PERTINENCE. Many of these images are really cool! But they are often ill-formatted and do not make sense in a "timeline" page. I am erring on the side of removing 'too many' images rather than too few.
2) Removing the tendency, especially later in the mission, for most paragraphs to be of the form "In Month XXth, Year, this happened". The content itself in these paragraphs will not be removed (unless it is irrelevant), but it will all be compressed into a more sensible format.
3) Removing the gallery. A timeline page does not need a gallery.
These changes are inspired by the effort of @User:Warrenmck, who drove similar changes in the Perseverance article. (Pinging you because you may be interested in these changes! I aim to drive similar reform on this page as you instituted for Perseverance, so if I've deviated from the spirit of the reform then do let me know.)
Given my experience on the previous change I proposed to this page, in which nobody participated, and the fact that this page does not seem to be actively updated, I am not going to wait around for a consensus on these changes. If you disagree, feel free to make your opinions known and we can work it out :) AlliterativeAnchovies (talk) 14:07, 2 September 2024 (UTC)
- I have left the "Self-Portrait" section of what was once the gallery intact. It needs to be reformatted, but given that the self portraits are portrayed in a timeline-like way, and could be used to understand the decay (or lack thereof) in Curiosity's condition over time, I feel as if it is a reasonable element to keep in.
