One
of the most useful results of the Space Race was the development of
satellite photography. Originally for reconnaissance, satellite imaging
is now primarily a commercial enterprise. Orbiting around 400km above
the Earth, Landsat and SPOT satellites produce images around 30km wide,
with details 10 to 20 metres across. The latest generation of satellites
have a narrower view, but resolve objects just one metre wide. From
orbits around 900km, weather satellites view a 1000km wide swath, resolving
details about 1km across. Out at around 36,000km are geostationary weather
satellites. These orbit once per day, appearing above the same point
on Earth, and capture the whole disc of the planet at once.
