Upon Orion's return from space, he appeared in a series of videos posted to Sesame Street’s Facebook pages on July 9, 2015. He and Ernie sit on the stoop of 123 Sesame Street with a metal NASA briefcase containing Rubber Duckie. Ernie is pleased to be reunited with him and paraphrases Star Trek: "he's been where no duckie has been before!" Arnold also brings back an Earth-orbited cookie to Cookie Monster that he promptly eats, and returns Grover's Super Grover cape, tying it around his neck.
Sometime in Q2 or Q3 2018, Arnold recorded an Elmotivation video from space which was posted on Sesame Street's social media feeds on October 13, 2018. Arnold appeared on the International Space Station with the crew of ISS Expedition 56: Andrew Feustel and Serena Auñón-Chancellor of NASA, Oleg Artemyev and Sergey Prokopyev of Roscosmos, and Alexander Gerst of the European Space Agency.
