The Gateway to Astronaut Photography of Earth

(NASA Crew Earth Observations)


















"We catch a glimpse of a huge swirl of clouds out the window over the middle of the Pacific Ocean, or the boot of Italy jutting down into the Mediterranean, or the brilliant blue coral reefs of the Caribbean strutting their beauty before the stars. And...we experienced those uniquely human qualities: awe, curiosity, wonder, joy, amazement." (Russell L. Schweickart, Apollo Astronaut ("The Home Planet")






Photographing the Earth from the International Space Station

Metadata: EXPO field

EXPO stands for exposure and indicates the film exposure quality. Possible values are "N" (normal), "U" (under-exposed), "O" (over-exposed), "F" (out of focus).

The qualitative nature of this field leads to subjectiveness in the data. There is no distinction between extreme or slightly underexposed/overexposed.

This field is not being cataloged beginning with STS093 (July 1999).
