{{incomplete|Made By a GUY WITH ONIONS IN HIS ROOM, HE ISN'T CYRING... . Do NOT delete this tag too soon.}}&lt;br /&gt;
&lt;br /&gt;
This comic is a paean to the {{w|Opportunity (rover)|Opportunity rover}}, and its nearly 15 year mission in which it sent back publicly available photos and research from Mars to Earth. The evening prior to this comic uploading (Feb 12, 2019), Nasa's JPL sent their [https://arstechnica.com/science/2019/02/opportunity-did-not-answer-nasas-final-call-and-its-now-gone-to-us/ final data request] to the rover, in hopes that it would respond. When it did not, the rover was declared to be officially lost.&lt;br /&gt;
&lt;br /&gt;
The comic starts with White Hat, looking at some people taking photographs and lamenting the fact that they're taking pictures all the time, saying &amp;quot;Kids these days...&amp;quot;, a common complaint of younger people by their elders.This is actually a straw-person argument, as White Hat is lamenting that the younger generation look at the world through their camera phones and thus don't experience it directly, and believe that they lose some of the joy of the event in the process - [[1314: Photos|an opinion he has expressed previously]].  &lt;br /&gt;
&lt;br /&gt;
To this Randall appears to counter that sharing and showing to others is an exciting part of the joy, an opinion which he has been sharing since before this comic{{Citation needed}}. He then proceeds to say that the Oppurtunity of exploring a completely new world is an exciting part of the exploration,and expresses joy in the fact that MER-B Opportunity was able to share its experiences in its 15-year, 45-kilometer journey on Mars with the entirety of humanity.&lt;br /&gt;
&lt;br /&gt;
The comic ends by thanking Rover (and NASA) for allowing the general public the incredible experiences it had on Mars in its 15 Earth-year lifetime , to receive the pictures and data, while traversing along hostile terrain for us.The last panel shows some &amp;quot;followers&amp;quot; which represents everyone on Earth listening to the words from Rover as it transmits the incredible experiences it had on Mars in its 15 Earth-year lifetime. Note, perhaps the reference to &amp;quot;dust devil&amp;quot; suggests these may have been the last such descriptions as that may refer to the deadly global dust storm that likely killed the Rover and ended the mission.&lt;br /&gt;
&lt;br /&gt;
The title text shows gratitude for the rover, which brought everyone on Earth, including Randall along in its journey by sending images of the journey to Earth.&lt;br /&gt;
&lt;br /&gt;
The Opportunity rover also appeared in [[1504: Opportunity]], while its twin rover Spirit also had a dedicated comic in [[695: Spirit]]&lt;br /&gt;

&lt;div&gt;&amp;quot;Wall (bathroom)&amp;quot; might be a reference to the Spaceballs movie. President Skroob is using the bathroom when he gets a video call from one of his officers. &amp;quot;Ahh! I told you never to call me on this wall! This is an unlisted wall!&amp;quot; [[Special:Contributions/172.68.54.112|172.68.54.112]] 16:31, 13 March 2017 (UTC)&lt;br /&gt;
:Or &amp;quot;Wall (bathroom)&amp;quot; is just a pun on &amp;quot;Wall (Unix)&amp;quot;. That would explain why only these two have disambiguation, and not &amp;quot;Telegram&amp;quot; or &amp;quot;Peach&amp;quot;. See also how both Walls are next to each other.

::Just curious - has Randall ever directly referenced explainxkcd? I know that he relies on us in minor ways, and I'm sure he reads explain, but I can't recall any actual references.

To whom are the individuals unique to some sets talking to?  eg those in Apache Request logs, and wall (unix) and wall (bathroom)?   I suppose there is no reason to assume anyone is receiving their messages.......[[Special:Contributions/108.162.241.160|108.162.241.160]] 18:37, 13 March 2017 (UTC)&lt;br /&gt;
:I'd assume that the diagram is the ways Randall communicates with people. So the person in the Apache Logs circle would be the only person he is able to reach using this method. Likely meaning that for the really big circles (like email), a person outside the circle doesn't necessarily mean they don't use email; just that Randall doesn't have their address. --(bah, I can't remember my username on here.

&lt;br /&gt;
This seems related to #1254, and maybe #1789 as well. Randall really has a problem with his friends' bizarre methods of communicating.[[Special:Contributions/172.68.132.5|172.68.132.5]] 18:44, 13 March 2017 (UTC)&lt;br /&gt;

;Related comics &lt;br /&gt;
I've created this new section at the bottom of the explain section. Those references don't explain much but moving it to a trivia section would move this out of sight for the reader. Since many writers like to find such references this chapter groups them all together. Any suggestions? --[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 19:04, 13 March 2017 (UTC)&lt;br /&gt;

::I like this and have also found [[1305: Undocumented Feature]] and the one where Randall made such a feature. Someone else included those mentioned above.

;Transcript&lt;br /&gt;
I'm thinking it may be best to do the transcript by listing each person and the circles in which they are present, possibly condensing people in identical circles with the number in parentheses. [[Special:Contributions/162.158.246.82|162.158.246.82]] 22:23, 13 March 2017 (UTC)&lt;br /&gt;
:I'm also thinking about this. But the persons are some sticky figures like Cueball and so on; the character itself is unimportant... Important are all the &amp;quot;Chat Systems&amp;quot; and their connections together.

::::I like the list of intersections, but that is part of the explanations. Have for the moment created a new section below the table.
