# A box-wing satellite 7000 km from Earth's center (about 620 km up), seen from 60 m
|
|
# with Earth's limb behind it.
|
|
#
|
|
# The camera looks 63.7 degrees from straight down. At this altitude the limb is
|
|
# 65.7 degrees from straight down, so it crosses the image about 2 degrees (320 px)
|
|
# above the center, with Earth below and space above. Image up is the local vertical.
|
|
#
|
|
# The satellite is turned so the camera sees it along its (+1, +1, +1) body diagonal,
|
|
# an isometric view of the +X (array side), +Y and +Z faces, with +Z toward image up.
|
|
# The Sun is placed to light those three faces and the Earth near the limb.
