This is Ground Control to Major Tom
You've really made the grade
And
the papers want to know whose shirts you wear
Now it's time to leave the
capsule if you dare
This is Major Tom to Ground Control
I'm stepping
through the door
And I'm floating in a most peculiar way
And the stars
look very different today
For here
Am I sitting in a tin can
Far
above the world
Planet Earth is blue
And there's nothing I can
do

Look-up, that is the altitude of the ISS orbit, which
appears not so far
away in the video.
Google seems to know it as a factoid as 370 km (230 mi).
That's about 30 times the long haul altitude for commercial
jet aircraft,
given to be 40,000 ft.
As far as actual looking up, to see spacecraft in the
night
sky, NASA has a web resource
here.

This is not really what the Earth at night "looks like" to an astronaut.
It's what the Earth looks like to an astronaut's camera, set for a long exposure
time and enhanced to show light sources the astronaut can't see due to the
limited latency of his retina. Or Earth through a telescope that amplifies the
light intensity to the point where the astronaut can see it - and that is
unlikely since the slightest daylight limb in the field of view would blind him
instantly.
The actual Earth to an astronaut doesn't look anything like this
observing directly with his naked eye. His view is no better than ours. [ Reply to This | Parent | # ]
