This scene shows a group of people hiking across the icy plains of Jupiter's moon Europa. Jupiter itself as well as another moon - Io - is seen beyond the horizon. The scene takes place on the night side of Europa so the landscape is lit entirely by reflected sunlight off Jupiter (and to a small extent off Io). The shot is designed to look as if it would have been filmed from a moving vehicle and with a very long lens so that the bulk of Jupiter fills the entire field of view, like a huge wall in the background.
The inspiration for this shot comes from this amazing photo
from January 1, 2001, taken by the Cassini spacecraft as it flew by Jupiter on its way to Saturn. It shows the moon Io passing in front of Jupiter and ever since I first saw it, I have tried to imagine what it would feel like to be standing on the night side of that moon, looking up at huge Jupiter, glowing in the sky. Now, this photo is also taken with a very long lens, so Jupiter, although huge, would not appear anything like this to a human standing on the moon.
For a person standing on Io, Jupiter would take up about 20 degrees of the sky, that is 38 times the size in the sky of our Moon as seen from Earth. That must still be an impressive sight. And from Europa, which is in an orbit further out from Io, and where this particular shot takes place, Jupiter would take up nearly 12 degrees of the sky, about 24 times larger than our Moon appears to us from Earth.
The ground in this shot is all CG with a mapping of different ice textures merged with colors from satellite photos of Europa, like this
, presumably taken by NASAs Galileo spacecraft. For Jupiter I used the highest resolution texture I could find, an assembly (of what I presume is photos from NASAs Cassini or Galileo spacecrafts) made by John Van Vliet for the virtual space simulator Celestia
. For Io, I used a tweaked version of this photo
taken by NASAs Galileo spacecraft.
