 Anyone wishing to download files, personal mail from anywhere in the world, or news bulletins could request the information be "broadcast" to all under the footprint of the spacecraft, or directed specifically to that ground station.This broadcast protocol differs from terrestrial packet radio communications, but allows a greater number of ground stations access to the spacecraft's resources during the limited time of a pass.A total of 10 megabytes of static RAM was used for message storage and a RAM disk.
