The outline for this article is now in place. All that's needed now is NASA to release more details on the mission so they can be filled in here.

Mission is still a go

I was concerned about the viability of the MAVEN project in the lights of the new colaboration agreement with NASA

Mars Joint Exploration Initiative
, however, I received e-mail confirmation from the highest possible source that it is still a go: "MAVEN is still a go, and it's on track for a 2013 launch. The joint initiative between NASA and ESA is looking at future missions beginning in 2016, that is, beyond MAVEN. I've received assurances from the highest levels at NASA that we are not being reconsidered as part of the joint effort and that we are not at risk due to the budget problems of other missions." --

Other proposals

More information about the other proposals is needed in the article. Why was MAVEN chosen and what were the characteristics of the other proposals? Cogiati (talk) 12:38, 5 August 2011 (UTC)[reply]

The article is about MAVEN, not the selection process. Besides I doubt there was an official discussion on the reason for their choice, there isn't usually. ChiZeroOne (talk) 13:38, 5 August 2011 (UTC)[reply]

Requested move (2013)

The following discussion is an archived discussion of the proposal. Please do not modify it. Subsequent comments should be made in a new section on the talk page. No further edits should be made to this section.

The result of the discussion was that the article should be named MAVEN (non-admin closure, unanimous result) --W. D. Graham 09:31, 22 May 2013 (UTC)[reply]

(but for the record, support

Support MAVEN as it looks like the most common use of that capitalisation. Neutral on Maven (spacecraft) vs Mars Atmosphere and Volatile Evoltion, oppose Mars Atmosphere and Volatile EvolutioN - it looks ridiculous and I'm sure there's a guideline against that kind of formatting somewhere in the MOS. --W. D. Graham 13:04, 9 May 2013 (UTC)[reply]
  • Please note that an improper technical request resulted in reverting to MAVEN after this RM had opened. So far we're good on this, but please make sure you explicitly state which name you favor, rather than just support or oppose. Apologies for the confusion. --BDD (talk) 22:09, 9 May 2013 (UTC)[reply]

Size of space craft

The article says "The orbiter has a cubical shape of about 0.20 m3 (7.1 cu ft), with two solar arrays holding the magnetometers on both ends.". This can't be correct? Berulfsen (talk) 21:04, 10 November 2013 (UTC)[reply]

 Done - Thanks for the heads up. It is 2.3 m x 2.3 m x 2 m high. [1]. -

Launch Window?

The side box says the planned launch date/time is 1:28, but the text says the launch window starts at 1:47... One of these is wrong, no? Tim-mnm (talk) 04:51, 14 November 2013 (UTC)[reply]

The 1:47 pm quote is an outdated time from September. I deleted it. Thank you, -

Apsis name for Mars

Periaeron or Periareion? Apoaeron or Apoareion? Wentu (talk) 15:19, 19 November 2013 (UTC)[reply]

I changed it to "areion", which seems to be the most common term. Interestingly, Aeron is apparently a Celtic god of battle. Muad (talk) 03:51, 21 November 2013 (UTC)[reply]

These terms are not used by NASA or the MAVEN team which instead use the generic terms periapsis and apoapsis. See http://lasp.colorado.edu/home/maven/science/science-orbit/ for an example. In fact, these object-specific terms seem to almost entirely exist only here on Wikipedia. It seems like they are part of the Infobox format so I'm not sure how to generically address this issue. Any help is welcome. Thanks. Jespley (talk) 19:39, 7 November 2018 (UTC) I figured out how to get the infobox to update so I've made the change I suggested. Jespley (talk) 16:35, 1 August 2019 (UTC)[reply]

NASA, NASA missions and other space agencies commonly use "apogee", "aphelion" and "apojove", for orbits around the Earth, Sun and Jupiter. A few people within the Cassini project insisted on "apokrone", but they were a small minority of the people involved. In all other cases, I've seen "apoapsis" used by those in the field.

Italicized title?

If MAVEN is a space probe, then should this article title be italicized like

Reason for the name

So where did the N in the acronym come from? The name is actually "Mars Atmosphere and Volatile EvolutioN Mission", with an apparently gratuitous final capital letter. (Mission FaceBook page) Clearly somebody wanted the acronym to spell a word, this word, maven, which is a loan from Yiddish. But I haven't found any authoritative mention of that, so I'm reluctant to add more to the article than the cap-N spelling and the reference. Can anyone fill that gap? Thnidu (talk) 01:22, 28 September 2014 (UTC)[reply]

checkY Found it and added it to ¶2 of § History. The source? The project's own Twitter feed! --Thnidu (talk) 06:16, 7 March 2015 (UTC)[reply]

Orbit

In reading the article, I am confused as to the state of the orbit. The infobox says that the orbital period is 4.5 hours, the included image shows a highly elliptical orbit of 35 hours with a later planned maneuver into a 4.5 hour orbit, and the article does not indicate when and if that maneuver has taken place. The article just says that the spacecraft entered orbit around mars. Another section indicates that the highly elliptical orbit of the spacecraft will limit its usefulness as a relay for operating landers on the surface. Can someone with more information clarify the status in the article? Neil916 (Talk) 16:48, 6 October 2014 (UTC)[reply]

I will take a look. I know that the science phase will be at a low altitude, and then it will be brought higher to function for many years as a communication relay satellite. Cheers,

A compact disc with haikus and messages

I entered a poem and received a certificate from the MAVEN mission. The CD containing messages from hundreds of people and hundreds of haikus written about Mars. I'd like to see a blurb about that in the Wiki article, since the CD is real(and kinda cool). Our words on MARS!

Surface radiation levels

I have deleted the last paragraph in the lede section because it was an exact duplicate of the last paragraph in § Results. Such detailed information does not belong in the lede section anyway, which is supposed to summarize, not repeat, the contents of the rest of the article.

Water loss - evaporation or sublimation?

In the section on atmospheric loss, it states "Mars loses water into its thin atmosphere by evaporation."

Surely at the temperatures on the surface and in the thin atmosphere of Mars, most of the water on the surface and sub surface will be ice. It will therefore deplete from the planet to the atmosphere by sublimation?

I have heard that there may be some melting of sub surface water ice in sunshine, but water ice easily sublimes in low temperatures and pressures. It is noticeable on cold low humidity days on earth that patches of ice can shrink without melting, e.g. icy road surfaces can become dry and bare of ice.
