Since there is no dialogue, the astronauts' names are not stated in the film itself. However, Ferguson has confirmed their names to be "Owen Wei" and "Wallace Marino".
Jupiter & Europa's production was extensively documented on Milo Ferguson's TikTok account, which is also how the film found most of its audience.
The flag and emblem found throughout the film is called "The Phoenix". As Ferguson states in one TikTok, "The red symbolizes sacrifice and contrasts with the icy blue of Europa, the inner circle represents Europa and what is known, and the outer circle represents Jupiter and what isn't yet known."
