Just before a SpaceX capsule docked with the International Space Station (ISS) so two astronauts who found themselves in space unexpectedly for nine months could prepare to return to Earth, an 'alien' was spotted on board on NASA's live feed.

SpaceX's Crew Dragon 10 astronauts Anne McClain, Nichole Ayers, Takuya Onishi and Kirill Peskov were the fortunate few to witness first-hand the moment as they arrived at the ISS in order to relieve Crew-9 from their observational duties in the black expanse of space.
