  ABSTRACT_TEXT       = "The Near Earth Asteroid Rendezvous (NEAR)            
Command and Data Handling (C&DH) system is designed to manage complex         
operations and to collect data when the spacecraft is out of contact          
with ground control. During ground contacts, the C&DH system accepts          
uplink commands and memory loads that describe a time-ordered set of          
events to follow, and it transmits previously recorded data back to           
the ground station. This article describes the overall C&DH system,           
gives details on each of the components, and tells how the system was         
tested prior to spacecraft integration. Solid-state data recorders and        
flight computers are also discussed."
