During the broadcast of the Artemis 2 mission flight and the live stream with the astronauts, a jar of Nutella suddenly appeared on camera.
They say it was accidental, not an ad. Either way, that jar could easily sell at auction (the first Nutella in history to have smelled the Moon).
P.S. Orbital advertising isn't new, by the way. Pepsi was the first to do it in 1985. And in 1991, Coca-Cola sent a special can to the ISS — the one Sergei Krikalev used to drink soda in space for the first time in history. But that's a story for another time. There's also the infamous shot of a Starbucks cup accidentally making it into Game of Thrones.
