You have to take into account that the scene is set on a terraformed
Earth's moon - with only one sixth of Earth's gravity, the atmosphere is
much less compressed towards the surface than on Earth (for example: on
Saturn's moon Titan, where gravity is slightly lower than on Earth's
moon, the atmosphere reaches as high as almost 1,000 kms above the
surface, and clouds hover at altitudes between 15 and 40 kms), so that
the tropopause (upper limit for clouds) will be much higher than on Earth.

Did you think of polar stratospheric clouds or of noctilucent clouds?
