Certain problem areas of current scientific and military interest lend themselves particularly well to investigation from Discoverer satellite orbits. These areas have been chosen for investigation with Lockheed Missiles and Space Division instruments in the first alternate payload. Data on the species, fluxes, energies, angular distributions, and time dependences of the nuclear radiations in the polar regions of the earth, for example, are necessary for a better understanding of the origins of such radiations and their effect on satellite performance. Also, more detailed knowledge of the primary cosmic radiation can lead to a better understanding of the nature and location of the sources of this radiation, its composition, and interaction with matter. The particular properties of the Discoverer satellite that make it unique for the measurement of polar and cosmic radiation are the following polar orbit low altitude of orbit attitude control feature and recoverability of portion of the payload.
