If you are here asking: "Is this a science meme?"
Probably, yes. We use the Dawkins definition of meme: a replicating idea, not just an image macro with a fact on it. A good post here doesn't need to teach you something. It needs to make you ask something: who, what, where, when, and especially why or how.
Science isn't a filing cabinet of facts, it's a conversation. For example, a photo of an eel or other localized wildlife counts because most people never see one, and wonder is the first step of inquiry. A car meme counts if it makes you curious about what's under the bonnet. If you want to talk about something you noticed in the world, chances are someone else wants to talk about it too.
We moderate for vibe, not category. Pruning is light, especially where a post creates interesting discussion. Experimenting is encouraged.
See the pinned paper on Shitposting as Public Pedagogy if you want the academic case for why this works.

Fun fact: Columbia, pictured with the white tank, was the heaviest shuttle and was not modified to have the airlock necessary to dock with the ISS because the performance losses compared to the other shuttles made it difficult to use for ISS operations.
But didn't it have ejection seats at one point?
IIRC the original Shuttle design called for an ejection mechanism around the entire cockpit. During STS-1 and I believe STS-2, which was also Colombia, there were extra emergency mechanisms present, but I don’t think the seats themselves ejected through the roof like a fighter pilot’s would. For the most part though these were useless as they could not be used above 30,000 feet or something like that so it could only be used during the first minute or two of the flight.
Several of the safety mechanisms and other things that were going to be part of the original design that had not already been scrapped for weight (like jet engines for powered decent) were scrapped for weight when the DOD stepped in and offered NASA extra money for the Shuttle if the Shuttle could hit very specific, higher and less fuel efficient, orbits. This came from an offhand comment that Jimmy Carter made, and then had to make good on the threats and implications of.
