[[Cueball]]'s reply, "NASA's good at orbital injections", is a pun on "orbital injection", also called {{w|orbital insertion}}, which is the adjustment of a spacecraft’s momentum that puts it into a stable orbit around a planet, moon, or other celestial body. Space agencies like NASA do this routinely on spaceflight missions. Getting an injection of a COVID-19 vaccine while in orbit aboard the ISS could also be called orbital injection, hence the pun. | [[Cueball]]'s reply, "NASA's good at orbital injections", is a pun on "orbital injection", also called {{w|orbital insertion}}, which is the adjustment of a spacecraft’s momentum that puts it into a stable orbit around a planet, moon, or other celestial body.

| − | The title text refers to the fact that, because the ISS orbits the Earth every 90 minutes, the people aboard it experience a day in that time, seeing a sunrise and sunset and crossing the International Date Line on the ground. | + | The title text refers to the fact that, because the ISS orbits the Earth every 90 minutes, the people aboard it experience a day in that time, seeing a sunrise and sunset and crossing the International Date Line on the ground. If one were to take this fact in the most ruthlessly advantageous sense, or else adopt the non-terrestrial rotation as your standard, it would mean 90 minutes on the ISS are equivalent to a day on the ground, making the people on board due for the second dose of the {{w|Pfizer vaccine}} (normally 21 days) or the {{w|Moderna vaccine}} (normally 28 days) after 31.5 or 42 hours, respectively, which [[Randall]] rounds to 30 or 40 hours. Incidentally, ISS clocks operate on {{w|UTC}}, the successor to {{w|GMT}}, rather than 'track' local time of the territories it passes above. |
