"Scientists sent radio signals to the lander on Mars, and instructed the lander to send back signals. Scientists then found that the time signals needed to make a round trip match the prediction of Gravitational Time Dilation."
Well, time dilation due to (rather feeble) gravity field of Mars will be many orders of magnitude smaller than delay due to uncertainty of Earth-Mars distance, delays in electronics which processes received signal and sends echo back, and even slight variations of signal propagation thru the solar wind.
If I am wrong, I would like to read about this experiment. Any URLs?
Sorry if this sounds like an obvious question but it just occured to me that the photos would have to have been transmitted electronically, meaning the photos could never have been film, right? The picture at the top of the article (with the rock left of centre) is of amazing quality for a digital camera of 1975. I never even knew they had them back then! -- Matt0401 11:49, 27 September 2006 (UTC)
I don't think "First panoramic view by Viking 1 from the surface of Mars" should be the largest image presented on the page, but rather be in the thumbnail gallery section. Altough it was historically significant, it is not otherwise a very remarkable image. For one, the sun angle makes for low constrast, making it hard to see features and texture. We should seek out a better main image. —The preceding unsigned comment was added by Tablizer ( talk • contribs) 04:25:07, August 19, 2007 (UTC).
I miss in the article references to Viking biology experiments, perhaps the most interesting part of the mission, at least for laymen like me. I remember clearly reading that the first reports indicated life-like activity and, later, this activity was attributed to effects of materials similar to earth clays. This deserves some explanation, I think.-- Ciroa 04:33, 3 September 2007 (UTC)
Was this the first landing of a man made spacecraft on Mars? The wording on the matter is somewhat ambiguous. —Preceding unsigned comment added by 70.48.128.21 ( talk) 04:05, 19 February 2008 (UTC)
As I understand it, Viking 1 operated on the surface of Mars for 2245 Sols. The Spirit Rover would have surpassed that on April 29th, 2010. However, as it is currently in(at best), a hibernation mode, it's unclear whether it did break the record. However, the Opportunity Rover has, according to JPL, now surpassed 2250 sols, (and is communicating regularly)which would mean Opportunity has clearly beaten Viking, with Spirit possibly having done so as well. When and how should this complicated situation be added to the wiki? ArrowQuivershaft ( talk) 03:05, 31 May 2010 (UTC)
Opportunity has reached 2450 sols as of May 2011
The spanish version of this article says that on 1982-11-13 a software update failed due to human error and that as a result the Viking 1 became non-operational. Has anyone hear this before? Alessio.aguirre ( talk) 16:27, 7 April 2011 (UTC)

"This first color image has since been lost or misplaced," (comma instead of period). This statement was added by an anonymous user: edited by 58.108.199.225 at 04:14, 3 June 2009.
There is no citation and in fact the first color image has since been added to the article and is easily available from many NASA websites as well as the official NASA archives.
There is some controversy about the sky color of the first color image. When the image was originally received the sky was incorrectly adjusted to appear blue, with a room full of reporters watching. A future image included a color calibration chart mounted on the lander and the first image was then readjusted to show the correct reddish sky color. While this is a somewhat interesting story that might be a nice addition to the Wikipedia article, I could not easily find adequate citations so I did not include it.
The sky color of Mars is a somewhat popular conspiracy theory but the first color image has not been lost or misplaced. That exact statement appears on several Mars Sky Color conspiracy sites and was probably added as "evidence" of a cover up. If the statement is added again, it should include a citation. — Preceding unsigned comment added by Kona Earth ( talk • contribs) 18:13, 22 November 2012 (UTC)
Hello fellow Wikipedians,
I have just added archive links to one external link on
Viking 1. Please take a moment to review
my edit. If necessary, add {{

Ok, so here the first picture (of unknown width) was apparently transmitted live in just 4 minutes, and the second full width one took a further 7.
However the general Viking Project page says the pictures are made of 9150 vertical scans of 512 pixels, at 5 lines per second... Which adds up to 1830 seconds, or just over half an hour, to my calculations.
Maybe it was meant to be 915 scans (so about 3 minutes), but that would make for some pretty wide pixels in such a panoramic photo wouldn't it? Especially if it was relatively short in the vertical dimension...
What's the truth of it? 88.151.211.42 ( talk) 00:45, 4 December 2015 (UTC)
The German band 'Tritonus' [2] had a song dedicated to the landing name 'Mars Dectecion' on their 1976 album 'Between The Universes'. In the summer of 1976, Hawkwind performed a song called 'Vikings on Mars' that later became 'Uncle Sam's on Mars' in the album PXR5. AMCKen ( talk) 06:12, 26 December 2015 (UTC)

Viking 1 is "the first spacecraft to land successfully on Mars and perform its mission"??
Seriously?
If this is the only article somebody reads about Mars exploration, he will be 100% positive that Viking 1 was "the first spacecraft to land successfully on Mars." But the "first spacecraft to land successfully on Mars" was NOT Viking 1, but the Soviet Mars 3, according to Wikipedia itself! See /info/en/?search=Mars_3
What's this? Lumping two distinctly separate events together to distort the truth?
Why am I not surprised? Because Wikipedia has a long time ago turned into a politically biased, ultra-left propaganda machine. — Preceding unsigned comment added by 45.72.224.212 ( talk) 06:39, 30 November 2018 (UTC)
