message: Somebody already made a reference to the Mars rock in Adirondack disambiguation page. So I went ahead and created the Adirondack (Mars) page taking content from the Adirondack section of MER-A (with slight modification). Obviously, now there's redundancy. Can I remove the Adirondack section from the MER-A page? - Kums 19:58, 14 Oct 2004 (UTC)
replies: text: Ok. I removed the section. The reason for this is 1)The MER-A Page is getting lengthy. 2) Adirondack has its own page. -- Kums 04:27, 31 Oct 2004 (UTC)

It's obviously a space ship. How else would the Martians be able to abduct people? They tried to hide it under the sand but didn't do a very good job, did they. :=)

replies: text: LOL. I first thought the Rover was losing pieces, but other images show it is the  raised central mark left by the grinding tool, before the dust is brushed away. The rock was particularly smooth and left a smooth disc-like impression, unlike the earlier samples which were porous and granular.-Wikibob 13:58, 2004 Mar 15 (UTC)
You're right it is an artifact of the rover's investigations. But I think what we're actually seeing is compressed sand rather than ground rock (prompted by your comment I went back to look at other images and I found some similar but less ambiguous pictures. The semi-circular footprint is left by an instrument that looks at soil chemistry (I forget the name), then imaged so that the physical properties of the soil/sand can be inferred from the way it is pressed down...

message: I noticed links to RAT on the MER-B article, which yesterday went to a disambiguation page that didn't have Rock Abrasion Tool listed. I added it, fixed up the links on the MER-A and MER-B articles, and wrote a Rock Abrasion Tool stub. I know that the RAT is covered on the Mars Exploration Rover article, but that article is getting very long and Wikipedia is now warning against expanding it and in favor of splitting it into multiple articles.
I just thought that those who contribute this content should know this. You might want to tear down my stub and link back to the MER article, or the MER article folks might want to start setting up separate articles for instrumentation and etc. I leave it to others.

:It might be running out of space due to all the pictures on it. And the same could be happening here. Maybe if each of those items was covered with its own article, then the pictures could be re-routed to those new articles. For example: my post on Pot of Gold Rock. If enough is known about this particular rock, then it could get its own article much like Adirondack did. Riffsyphon1024 05:42, 26 Jan 2005 (UTC)

message: "First color photograph", etc. is clearly stating that Spirit is taking color photos.
This is not true in the stict sense.  The color images are constructed by taking
photos of the same thing using different filters.   Note that the filters are not
the same as the RBG pigments in the human eye thus the color is not exactly
what a human would see. Also one would hope the lighting does not change too much in the time it takes to take the photos: usually three (six if one takes photos with both left and right cameras).
It would be more accurate to say, the "first color image released" or "first color image generated." MichaelSH 01:55, 21 July 2006 (UTC)
replies: text: You raise good points, but at the same time you don't want to obscure that the Pancam is a multispectral instrument.  Perhaps "first color image generated from rover data"?  Eluchil404 02:21, 21 July 2006 (UTC)

message: Something is not right in the part where it state the power produced is 700 watts per day. Power is the measument of energy transfer per unit time (1 watt = 1 joule per second) and saying 700 watts per day implies a the power output changes by 700W per day, every day. The power output should be measured in watts alone, or the total energy produced per day could be measured in watt-hours. 700W sounds like a lot for a small solar panel like that to produce, especially on Mars, so maybe it should read watt-hours. Inductiveload 02:24, 10 August 2007 (UTC)
replies: text: Watt hours is the unit usually used by the rover team.  700wh may be what the arrays are rated for though I haven't heard of them producing more than about 650 in actual martian conditions.  At the moment, however, the ongoing dust storm has limited output to much less--under 200wh at the lowest.  Eluchil404 20:07, 10 August 2007 (UTC)

text: The idea of differentiating vehicles being held "down" on a surface by the gravity of the astronomical body is logical enough.

message: The use of 'yards' may indicate meters in source data. A journey described in the article as '400 yards' to a crater that is '150 yards' across, was probably originally reported by scientists as 400 meters and 150 meters. I assume that modern NASA source data is metric by default. My impression is that now it is only the media (including NASA's own press officers) that persist in making it hard to work out whether source data is metric or non-metric.
This issue happens in multiple space articles. But there are multiple Wikiprojects for space articles. Does anybody have a suggestion as to which Wikiproject is the most likely to address this issue? Lightmouse (talk) 14:23, 4 January 2008 (UTC)
replies: text: While scientists generally work in meters, NASA press releases are often in yards.  We should probably report whatever our cited sources do.  One could also convert, but with round numbers conversions give weird results.  Eluchil404 (talk) 22:59, 4 January 2008 (UTC)
replies: text: Indeed. The NASA press office makes things difficult. I cannot find any source for the 'yard' values given. There are respectable sources with meter values. I think the converted yard values should be replaced with original metric values but I do not know that much about the subject. Lightmouse (talk) 11:16, 5 January 2008 (UTC)

message: As a visitor with no knowledge of (but a sudden curiosity in) this mission, I've found it next to impossible to discover 1) where the rover is now 2) what it has done recently.  I assume via vandalism, the years 2006 and 2008 seem to be used interchangeable (see Low Ridge Haven, Home Plate, etc). Could someone who follows this patrol the dates, assign earth dates to each Sol date (as is done in some places but not others), and give some idea of what the timeline is/has been, perhaps in a section lead? I know it's annoying to have strangers come and tell you what to do, but this is an article which is both very high profile and which follows events that on a day-to-day basis are quite obscure to us non-experts.

message: It is noted in the intro that when the rover became stuck, it had operated 21.6x its planned mission duration.  For the introduction I should think that should be sufficient, such that noting that contact efforts continued until 24.6x mission duration and mission was not declared terminated until 25.2x mission duration is excessive detail.  I would think it would be too much to declare mission duration for a large number of things the rover did when it was operating and communicating, never mind when it was not.  It was fully functional for more than 20x planned duration.  Good for Spirit.

Personally I find is to be the better choice.  Though the contact was lost with the rover and it is no longer active.

message: A Martian year is 686 Earth days as opposed to our year of 365 Earth days.  I know some of these you may think "well it should be obvious" but nothing is obvious when it comes to folks reading an encyclopedia page.  People just aren't used to converting time units which here on Earth are constants for all intents and purposes, but once you step off of Earth are not.  It's like the distinction between Newton's laws of gravity and Einstein's - Newton works for most everyday stuff, but when we're talking about being on Mars, we need the more specific explanations, including timekeeping on Mars but not only using "sols" for days.
The following bits are ambiguously stated in length to an amateur:
:On May 1, 2009 (5 years, 3 months, 27 Earth days after landing; 21.6 times the planned mission duration)
This is confusing - are only the days in Earth units?  If the entire timeframe is Earth units, it should say that before spitting out the numbers: "In earth time units: 5 years, 3 months, 27 days"
:Towards the middle of the six-year mission (a mission that was supposed to last only 90 days)
Again, Earth years or Mars years?
I'm not trying to start an argument or be picky, but kids (who may indeed possibly find themselves translating Earth time to Mars time on their way there) read this article and clarity should be maintained.--Varkman (talk) 10:12, 7 January 2016 (UTC)
