What was the orbital radius of the Elysium toroid?
When the first group of 3 ships sent by Spider were traveling towards Elysium, the movie cut to Defense Secretary Delacourt at a party at her home. She left the party and went to the command center. Once she had arrived, there was an announcement that said the distance was 15,000 Kilometers, and at the same moment, it flashed to a read out of
ETA 12:43.999 seconds
Later when Kruger was traveling to Eylisium, he spoke to her briefly before departure, and she said:
See you in 19 minutes.
Spider left shortly thereafter in one of his own ships, and arrived shortly after Kruger (suggesting the two craft were about equivalent in acceleration/speed).
So it should, I suspect, be possible to work out the total distance based upon that.
- I had originally thought that as they were cutting from the first 3 ships still accelerating, to when someone moments later said they were approaching Elysium that the movie had made a goof, and the ships should be decelerating at the time. Given they were still 15 minutes away suggests not, and the 'approaching' did not mean 'close' but simply 'on a trajectory towards'.
- The ships apparently had some sort of inertial dampener to counteract the effects of acceleration, as again while the 3 ships were still accelerating, the movie cut to a view inside one of the ships and showed objects floating around the cabin. (Oh, those Earthbounds, you can dress them up in a false bar-code but you can't take them anywhere without them littering the dang ship..)
