1. STS028-093-096 – A portion of the film carried aboard the Space Shuttle each mission
is sensitive to color infrared (CIR) light. Healthy vegetation strongly
reflects near-infrared light, and, therefore, registers a strong response on
CIR film. Here, healthy vegetation in the Scottsbluff area is depicted in red.
Images such as this are useful for mapping agricultural land cover and, when
compared to similar images from other times, land-cover change. (Aug. 10, 1989)

2. STS059-219-022 – A band of snow blankets the area west of Holdrege
(the town is visible at highway intersections) and south of the Platte
River in south central Nebraska. This detailed, near-vertical photo reveals
patterns of agricultural land cover, transportation, and drainage. Numerous
round-shaped fields, irrigated with center-pivots, dot the landscape.

3. STS059-090-065 – The ability of astronauts to image the Earth at
any oblique angle, thus capturing regional views, makes Space Shuttle
photography unique in space-based sensoring. Centered on the Sand Hills,
this photo depicts all of western and southwestern Nebraska, as well as
parts of South Dakota and Colorado. Visible at upper left is the
Earth's curvature, or limb, and our planet's thin, blue atmosphere.
The round, dark land mass nearby is the Black Hills of South Dakota.
Several water bodies along the Platte Valley are apparent, including Lake
McConaughy and Sutherland Reservoir near center. East of North Platte,
which can be seen near the confluence of the North and South Platte Rivers,
are two bands of snow, one north and one south of the Platte River Valley.
