# Sunset: Landsat 8 in its 705 km orbit, 1.4 s before the straight line to the
|
|
# Sun's center touches the ground. Its sunlight crosses the lowest 25 km of the
|
|
# atmosphere edge on: at lighting L1, 7.2 % of the Sun's red light reaches it,
|
|
# 4.8 % of its green and 4.4 % of its blue, and it is lit orange-pink. The solar
|
|
# array faces halfway between the Sun and the camera, an inspector 170 m away
|
|
# looking 45 degrees across the Sun's direction at Earth's limb, where the
|
|
# twilight glows orange under blue. At lighting L0, without the atmosphere, 71 %
|
|
# of the Sun is above Earth's bare edge, and the satellite saturates at this
|
|
# exposure. Generated by scripts/make-example-scenes.py; the model comes from
|
|
# scripts/fetch-models.sh.
