The first multispectral photography done from space was on the famous 1968 Apollo 9 manned mission. Four Hasselblad cameras were mounted in a holder such that they all aimed at the same target point when their shutters were triggered simultaneously. Below are three filtered b & w photos of southern California around San Diego were taken in the green,

red,

and photo IR bands;

the fourth was a (false) color IR picture.

A 6-camera multispectral system was flown on the Skylab spacecraft occupied by several crews between May 1973 and February 1974. The value of multispectral photography was quickly recognized by discipline scientists, particularly geologists, hydrologists, agronomists, foresters, and those concerned with environmental monitoring and land use/cover assessment.
