&lt;br /&gt;
==Explanation==&lt;br /&gt;
{{incomplete|Needs citations.}}&lt;br /&gt;
&lt;br /&gt;
This comic is talking about the robotic science platform {{w|Opportunity (rover)|''Opportunity''}}. On January 25, 2004, the ''Opportunity'' rover landed on the surface of {{w|Mars}} for the purpose of gathering data about the surface of Mars.&lt;br /&gt;
&lt;br /&gt;
Also sent to Mars on the same date was another Martian rover, {{w|Spirit (rover)|''Spirit''}}. Unfortunately, this became stuck and a sand storm covered its solar panels. On March 22, 2010, it is thought that ''Spirit'''s batteries finally ran out, marking the end of its mission. This was memorably covered in [[695: Spirit]], in which the ''Spirit'' rover is portrayed as sentient.&lt;br /&gt;
&lt;br /&gt;
In 2015, the Opportunity rover is still alive and moving, amazing the scientists at ground control.&lt;br /&gt;
&lt;br /&gt;
However, in 2023, Opportunity has apparently become so powerful that it has become dangerous, presumably cannibalizing or destroying the {{w|Mars 2020|rover sent in 2020}}.  Cueball and Megan note it even continues to operate without its original battery, suggesting it has developed a new power source.  This evolution is similar to the stories of {{w|HAL 9000}} (from {{w|2001: A Space Odyssey (film)|''2001: A Space Odyssey''}}) and {{w|List of Star Trek characters (T–Z)#V'Ger|V'Ger}} (from ''{{w|Star Trek: The Motion Picture}}''), both of which became sentient and dangerous.&lt;br /&gt;
&lt;br /&gt;
By 2450, humans have colonised and terraformed Mars. “Everything the light touches” is a reference to what {{w|List of The Lion King characters#Mufasa|Mufasa}} says in ''{{w|The Lion King}}''. (Mufasa's son Simba then asks &amp;quot;What about that shadowy place?&amp;quot; and Mufasa tells him “That is beyond our borders. You must never go there”.) What this all implies is the ''Opportunity'' has dominated half of the planet.&lt;br /&gt;
&lt;br /&gt;
The title text refers to the first words of the first astronauts on the surface of Mars. At first, the astronaut copies the first words of Neil Armstrong on the Moon (&amp;quot;That's one small step for [a] man, one giant leap for mankind&amp;quot;) but it is interrupted by the ''Opportunity'' rover. Onboard the rover uses a drill for sampling rocks, but here it uses it to attack the astronaut.&lt;br /&gt;

2010:&lt;br /&gt;
Ponytail (at a computer): After six years, Spirit is down, but Opportunity is still going strong. &lt;br /&gt;
&lt;br /&gt;
Hair Bun: Tough little rover!&lt;br /&gt;
&lt;br /&gt;
2015: &lt;br /&gt;
Opportunity:&lt;br /&gt;
Eleven years, wow!&lt;br /&gt;
Wasn't the original mission 90 days?&lt;br /&gt;
This is starting to get weird.&lt;br /&gt;
&lt;br /&gt;
2023:&lt;br /&gt;
Cueball: The battery is totally disconnected! How can it still be moving?&lt;br /&gt;
Megan: Given what it did to the Mars 2020 rover, we may never know. &lt;br /&gt;
&lt;br /&gt;
2450, Tereaformed Mars, Mars Imperial Capital:&lt;br /&gt;
Cueball and Megan are standing on a Martian cliff near a sci-fi city. &lt;br /&gt;
&lt;br /&gt;
Cueball: Everything the light touches is our kingdom. &lt;br /&gt;
Megan (pointing to some distant mountains): What's that dark area?&lt;br /&gt;
Cueball: That is Opportunity's half of the planet. We must never go there. &lt;br /&gt;
