:I've added an explanation for the title text but am unsure of the "engineering standpoint". Maybe someone with knowledge in the area can elaborate on that. Is landing inherently more difficult than launching?[[Special:Contributions/162.158.88.128|162.158.88.128]] 08:42, 19 March 2019 (UTC) | :I've added an explanation for the title text but am unsure of the "engineering standpoint".

Probably about how the engineers wanted to test what they could do before they could actually do it. (Oh,and Luna 2 impacted at 22 km/s) 20:10, 18 March 2019 (GMT) | Probably about how the engineers wanted to test what they could do before they could actually do it.

:::Hilarious how some people might actually believe this, but Explainxkcd isn't a place for people to shitpost. If you see things like this in an explanation just revert it immediately.

:The actual sad part is it probably isn’t a joke. At least it’s a long and drawn out poorly constructed one. People are idiots, and flat earthers can be real. This person isn’t making fun of them. Not in a helpful way at the very least. [[User:Netherin5|Netherin5]] ([[User talk:Netherin5|talk]]) 14:00, 19 March 2019 (UTC) | :The actual sad part is it probably isn’t a joke.

Not sure how to tan on mobile (feel free to do so and delete this tidbit if you want to) but: The throwing a frag filled with flags is symbolic of the standard human explorer tactic. Basically, we tend to shoot first whenever we go to a new place and then promptly place a claim, whether the preexisting landscape has been claimed or not. For instance, the Native Americans. Like, all of them. The tile text, on the other hand, represents attempts to find a solution to half a problem or maybe representing the aforementioned claims bit. But I could be reading into this too much [[Special:Contributions/172.69.46.58|172.69.46.58]] 17:22, 18 March 2019 (UTC) | Not sure how to tan on mobile (feel free to do so and delete this tidbit if you want to) but: The throwing a frag filled with flags is symbolic of the standard human explorer tactic.

:That impact speed still sounds ridiculously high, Escape velocity to break free of earth orbit is, IIRC, 11.186 km/s (roughly 40K kmph or 25K mph), and it takes a massive rocket to achieve that. Most of a trans-lunar flight is unpowered using either momentum built up by the initial launch thrust or the gravitational pull of the moon itself. I find it hard to believe that impact speed, even allowing for gravitation influence of the moon itself, could result in an impact at almost 2X the speed needed to get away from Earth in the first place.[[User:RAGBRAIvet|RAGBRAIvet]] ([[User talk:RAGBRAIvet|talk]]) 07:24, 19 March 2019 (UTC) | :That impact speed still sounds ridiculously high, Escape velocity to break free of earth orbit is, IIRC, 11.186 km/s (roughly 40K kmph or 25K mph), and it takes a massive rocket to achieve that.

::22 km/s seems to be wrong. Wikipedia along with a few quick google searches put the impact speed at around 3 - 3.3 km/s. To me (far from an expert) that appears more realistic but still fast enough to cause significant damage. Whether things are literally vaporized at those speeds I leave for others to determine.[[Special:Contributions/162.158.94.2|162.158.94.2]] 11:31, 19 March 2019 (UTC) | ::22 km/s seems to be wrong.

: Or (as I suddenly realized) maybe you are asking to navigate from [[2124]] to [[2125]]. The "next>" button also worked fine as of this comment. --[[Special:Contributions/103.22.200.210|103.22.200.210]] 01:45, 19 March 2019 (UTC) | : Or (as I suddenly realized) maybe you are asking to navigate from [[2124]] to [[2125]].

:: The "NEXT>" button from [[2124]] was missing for most of the day, but looks like someone eventually fixed it.
