Explanation:
Launched last month, NASA's
Landsat 7 spacecraft
now orbits planet Earth.
Looking down from an altitude of 700 km,
Landsat 7 can map
the planet's surface in visible and infrared
bands and
resolve features 30 meters across or smaller.
For example,
this striking engineering test image is
a natural-looking color composite of 3 different
visible wavelength bands.
It nicely shows details of urban areas around San Francisco,
California, USA,
nestled in the surrounding terrain (north is up).
Flowing blue-green
colors track the spring runoff from
the Sierras to the west and neighboring mountains into
the bay and out into the Pacific ocean.
Landsat 7 is
currently performing well in its check out phase
and controllers are preparing the satellite for
regular operations.
