History of Remote Sensing: Apollo 9 Multispectral Images

The first multispectral photography from space happened during the famous 1968 Apollo 9 mission. Scientists mounted four Hasselblad cameras in a holder such that they all aimed at the same target point when an astronaut triggered their shutters simultaneously. Below are three filtered b & w photos of southern California around San Diego, which the astronauts took in the green, red, photo IR bands, and a (false) color IR picture.

A six-camera multispectral system flew on the Skylab spacecraft, which several crews occupied between May 1973 and February 1974. The photos they took helped show the value of multispectral photography to discipline scientists , particularly geologists, hydrologists, agronomists, foresters, and those concerned with environmental monitoring and land use and cover assessment.
