A radio altimeter could be used to index the height at which each picture was taken. The camera system, developed by the Eastman Kodak Company for the Air Force, would be available within the year. The alternative approach of using direct television appeared less attractive because the resolution of the television system was at least an order of magnitude lower than the comparable photographic system. Because of the difficulty in placing an instrument package in a close lunar orbit, photographs taken by a vehicle orbiting the moon, including those taken of the far side and recorded on magnetic tape for later transmission, would probably have low resolution owing to the distance from the lunar surface. On June 12, Rosen described a new television system which could be used for early attempts at lunar photography. The system, which would be available within a year, would relay pictures comparable to that of the Eastman Kodak camera system.
