Cow on Mars?![edit]

Hmmmmm... I don't think this is a picture of Mars... —Preceding unsigned comment added by 192.220.139.80 (talkcontribs) 22:31, 14 July 2005

OK, while I was typing this, the picture of a cow was replaced... —Preceding unsigned comment added by 192.220.139.80 (talkcontribs) 22:32, 14 July 2005

Source?[edit]

The following is listed in the entry "....shook the scientific community." Is there a source for this? Specifics concerning this aren't mentioned at all. Pgrote 20:26, 16 November 2006 (UTC)

I rewrote the sentence a bit to make it more Wikipedia-ish. Van der Hoorn (talk) 22:53, 13 February 2009 (UTC)

Where is it now?[edit]

Where is this probe now? Helocentric orbit or what? —Preceding unsigned comment added by 67.121.234.90 (talkcontribs) 03:15, 8 April 2006

I don't know exactly where, but it's in a exterior Heliocentric orbit. Most planetary probes are in heliocentric orbit initially, then have to adjust their trajectories to orbit or land. CFLeon 06:30, 25 August 2006 (UTC)
Added it to the article. Van der Hoorn (talk) 14:55, 12 February 2009 (UTC)

Intelligent life hopes[edit]

I'm a bit sceptical about the sentence: Images of craters and measurements of a thin atmosphere, indicating a relatively inactive planet exposed to the harshness of space, generally dissipated hopes of finding intelligent life on mars. Was there really any serious hope of finding 'intelligent' life on Mars just before the M4 probe? (As opposed to just the hope of finding 'complex' life such as plants and invertebrates). Ashmoo 01:08, 14 July 2006 (UTC)

Also the shook the science community' from the intro seems more appropriate for a pop-science article rather than an encyclopedia. The data gathered from M4 was well within the range of expected outcomes wasn't it? Ashmoo 01:29, 14 July 2006 (UTC)

This article is lean on sources. I vote for removing '..shook the science community' unless there is something backing this statement up. Maybe the hopes-statement should be removed too. (Although I think this sentence may be true: it doesn't mention the scientific community and in the general poblic maybe many stil had hope before the M4 probe) Pukkie 09:48, 14 July 2006 (UTC)
Agreed. Unless there's some evidence that the scientific community, as opposed to the science fiction community - really expected there to be life on Mars at the the time, this is a statement that needs to be backed up with a citation or removed. And Mars needs to be capitalized in the life on mars line. --Don Sowell 23:02, 14 July 2006 (UTC)

Added content based on before mentioned references. Van der Hoorn (talk) 11:58, 13 February 2009 (UTC)

Recontact[edit]

The page doesn't really address the 1967 recontact, only mentions the final lost of contact. Can someone put up some info about this? CFLeon 06:33, 25 August 2006 (UTC)

Midcourse correction accuracy[edit]

The article states the pitch/roll change was completed to "better than 1% accuracy". Shouldn't it read "better than 99% accuracy" or "better than 1% error" instead? Eridane (talk) 19:32, 29 January 2010 (UTC) I agree. The reference cited is a NASA document that includes the same error. Wikipedia's generally accepted policy is that we can't perform any original research, so we're left with having discerning readers figure this out on their own, or just read our comments!Raryel (talk) 15:48, 13 November 2011 (UTC)

Copy Edit Needed[edit]

The article needs a good copy edit. Should probably be a high prioity to-do. Schaffman (talk) 14:57, 18 April 2011 (UTC)
