It’s been a standard thing for NASA to take group photos of every crew it launches into space. Aside from the purpose of documentation, these photos are usually used for promotional posters for the expeditions.
Once in a while, however, astronauts would go bored with the ho-hum, generic squad poses and would opt for more creative posters filled with pop culture references.
Thank God NASA approved such an idea, ’cause the results are simply hilarious.
